Quiet & Lukewarm

"Modis" High Resolution NASA "Terra" Satellite Image. This low-orbit (250 mile above the ground) satellite image was taken late Monday. Click here to go directly to the NASA site, where you can see extremely high resolution data, including the massive smoke plume from the wildfires raging just north & east of downtown Los Angeles and Burbank. For the record you can also see incredibly high-resolution imagery of Minnesota.


Remind me not to complain about frost reports in late August. Suddenly the premature frost up north - and the nagging moderate to severe drought conditions - even the random, unpredicted tornado that skipped across South Minneapolis ALL OF IT seems fairly insignificant compared to the epic fires gripping southern California, and the borderline Category 5 hurricane bearing down on Cabo San Lucas (where I'm supposed to be fishing for marlin in exactly 3 months).

Come to think of it, Minnesota sees a large volume of whine-worthy weather, no question: frost in late August makes for great watercooler babble, the cold does last an awful long time at this latitude, and no, there is nothing more irritating than seeing fresh snow fall on a freshly mowed (green) lawn in late April or May. Annoying? Yes. Cataclysmic - Apocalyptic? No. Most of the time nature is irritable, not demonic enough to actually kill you, just annoy you half to death.

Can you imagine tracking a 400 foot tall wall of flames advancing across the map, plumes of smoke, fire and ash that produce hellish "tornadoes" of flame? One minute: blue sky, palm trees. The next minute: horizontal winds blowing ash and flaming cinders, screeching fire trucks, screams of people trying to evacuate. The fires gripping the Los Angeles are not the classic Santa Ana fires triggered by air howling down the canyons toward the Pacific. This is the result of an extended drought, too much fuel/brush burning, and no good way to stop the flames in time. What firefighters and homeowners really need is a decent size tropical storm or hurricane to quench the flames. That's where Jimena may come in: monstrous, borderline Category 5 hurricane Jimena now steamrolling north, toward Cabo San Lucas. After roughing up the picturesque Mexican fishing village by midweek the soggy remains of this (weakening) hurricane are forecast to spread north, right up Baja Mexico, and it's conceivable that moisture leftover from this tropical system could spark some badly-needed rains across southern California by the weekend. Stranger things have happened.

NHC Projected Path of Jimena. Monday sustained winds were 155 mph, just 1 mph away from a Category 5 super-hurricane. The storm is expected to track to the north/northwest, giving a glancing blow to Cabo San Lucas Tuesday (the city will be on the rough side of the storm, vulnerable to a storm surge of 5-15 feet above normal high tide). The main circulation over Baja California, Jimena should weaken as the week goes on, possibly holding together long enough to spark heavy rain for the Phoenix area by early next week.

In stark contrast to the raging fires, surging seas and horizontal rains in the forecast from southern California on south to Cabo - Minnesota's weather looks downright tame this week, dry, seasonably warm, no drama - nothing severe, fine weather for the Minnesota State Fair (and the start of school across the state). If anything it may be a little warm and stuffy in some of those classrooms, the mercury closing in on 80 in time for the Labor Day weekend. Any showers and storms should slosh off just south/west of Minnesota this week - I don't see any significant chance of getting wet until sometime Sunday or Monday (Labor Day). The GFS computer model is hinting at a cool frontal passage on Labor Day, maybe a couple hours of PM showers and T-storms. At least it should be warm enough for the lake or pool - one last crazy splash. Daytime highs approach 80 by the weekend, not exactly Dog Day material, but warm enough. The way this "summer" is going, I no longer take 80 for granted.

Could it be that 80 is the new 90?

Sorry - I think I got a little too much sun yesterday.

Frosty rumors up north

Graphic courtesy of the Twin Cities National Weather Service.


* Suburbs waking up to the 30s for the first time since May 16! I know, it's way too early to be tossing around the F-word. Frost in late August? Keep in mind that "meteorological summer", marking what is historically the warmest 90 days of the year - think of this as REAL summer, goes from June 1 to September 1. As far as the atmosphere is concerned true autumn really kicks off tomorrow. Gazing at the mercury in my back yard thermometer - no, better yet trying to FIND the mercury in my back yard thermometer this morning that's not hard to believe!

No, this doesn't (necessarily) mean a shorter autumn, an earlier winter, a more severe winter, or that health care reform will become the law of the land. It is what it is - a fluke, an aberration, another odd little weather gyration. We've been seeing a lot of those lately, haven't we?

No, it's not your imagination.

* 27 F. at Embarrass, MN Sunday morning - coldest in the state (possibly the coldest anywhere in the lower 48 states!) 32 degree low at International Falls, Ely, Silver Bay and Crane Lake.

* 36 F. reported Sunday morning at Little Falls and Benson, 35 at Hayward, Wisconsin.

* Frost advisory in effect north/east of Lake Mille Lacs during the early morning hours. Combination of dry, Canadian air, clear skies and diminishing winds should create ideal conditions for a rare, late-summer frost for parts of northeastern MN and northern Wisconsin.

* Monday morning record low of 40 degrees in the Twin Cities in danger of being broken.

* St. Cloud record for August 31: 33 F. set in 1974

* 62 degree "high" at Eau Claire, WI Saturday - sets a record for the coolest August 29 on record.

* 68 degree high at MSP Sunday, 69 in St. Cloud.

* Dry week shaping up - showers/T-storms remain just south and west of Minnesota through the period.

* It's early but right now next Saturday appears to be the best outdoor day of the Labor Day weekend. Scattered showers and T-storms likely Sunday and Monday, not a steady rain, but a few hours of showers possible each day.

* Highs mostly in the mid to upper 70s every day this week, near 80 by the weekend (with higher humidity levels).

Paul's Outlook


Today: Frosty start north/east of Lake Mille Lacs. Plenty of sun, a bit milder. Winds: S 5-10. High: 74

Tonight: Mostly clear, still cool. Low: 49

Tuesday: Warm sun, hard to concentrate. High: 76

Wednesday: Dim sun through high clouds, showers/storms should stay south/west of the area. High: 75

Thursday: Mostly sunny, still dry. High: 77

Friday: Great start to the holiday weekend - generous sunshine. High: near 80

Saturday: Partly cloudy, possibly the nicest outdoor day. High: 78

Sunday: More clouds, a few scattered showers/T-storms. High: 76

Monday (Labor Day): Intervals of sun, sticky, a few more showers/storms. High: 77

Sweatshirt on a Stick

I know - it's a little cool for late August. I won't have to recite the windchill reading; suffice to say you may want to grab a light jacket or sweatshirt before heading out the door this weekend. A crisp, Canadian breeze will make it a bit harder to find the mercury in your backyard thermometer, daytime highs stuck in the 60s across much of Minnesota - computer models hinting at some 50-degree highs over far eastern MN and Wisconsin later today.

Sunday still appears to be the nicer day of the weekend, less wind (as high pressure drifts directly over our heads) and more sunshine - fewer instability cumulus clouds puffing up during the PM hours, afternoon highs well up into the 60s. Given a choice in the matter I would plan my State Fair Adventure for Sunday.

WRF/NMM Temperatures for 7 pm this evening. It gets milder the farther west you travel across Minnesota - check out the big swirl of 50-degree readings over Wisconsin and far eastern Minnesota.

Frost Update. Try not to panic. Just seeing the F-word in August is enough to send a small percentage of Minnesotans into convulsive, screaming fits. "Frost in late August - what does that mean for October?" I guess I'm not shocked, we've had a tentative summer, July and August running cooler than average - fewer 90 degree days, not nearly as many sweaty, sticky, 70-degree dew point days (which I'm just fine with, btw). The WRF/NMM model is still hinting at some 30-degree lows Sunday morning, mainly north, toward Sandstone and Hinckley, and just south/east, toward Hastings, Cannon Falls and Northfield. I'm a little more inclined to believe that some of the coldest nooks and crannies of northeastern MN, near Embarrass, Tower and Ely, could wake up to an isolated frost. Right now this does NOT look like a widespread frost (or killing freeze of 3-5+ hours below 28, capable of killing off all annuals). I think we'll have a bit too much of a breeze and residual cloud cover for that.

Forecast temperatures for 7 am Sunday morning. The epicenter of the cold air appears to be just south/east of the Twin Cities.

Danny, where are you? This morning's satellite image shows a very disorganized tropical storm Danny being swept northward, absorbed into an area of low pressure which will soak much of the mid Atlantic states and New England. But Danny proved to be something of a tropical disappointment. The computer models were (all) wrong. They predicted Danny would strengthen into a hurricane and remain just offshore. It never happened, the result of too much wind shear aloft or ocean water temperatures not as warm as predicted? Again, it's worth repeating: NHC, the National Hurricane Center, does a MUCH better job predicting the track of tropical storms and hurricanes than they do with intensity, by an order of magnitude it's easier to predict where a specific storm will go, then whether it will be a tropical storm, a category 1 or a category 4 storm.

Enough distractions, back to Minnesota weather. Dry weather prevails next week, in fact I don't see much of any chance of showers or T-storms until the Labor Day weekend (of course!) Could have predicted that 6 months ago, right? Temperatures will remain close to average for late August/early September, with highs in the mid to upper 70s, although the GFS model is hinting at 80+ by next weekend, maybe well into the 80s for Labor Day Monday (with a few rough T-storms around). Stay tuned.

Paul's Outlook for Greater St. Cloud

Today: Morning sun, PM clouds, a cool wind. Winds: N/NW 10-20. High: 64

Tonight: Clearing, chilly for late August. Isolated, patchy frost possible from near Mille Lacs northward to Embarrass and Tower. Low: 39 (probably no frost within 50 miles of St. Cloud)

Sunday: Bright sun, lighter winds. High: 68

Monday: Sunny and beautiful. High: 74

Tuesday: Warm sunshine, still dry. High: 76

Wednesday: Partly cloudy, showers probably pass south/west. High: 77

Thursday: Mix of clouds and sunshine. High: 75

Friday: Promising start to the holiday weekend. Plenty of sun. High: 78

Saturday: Partly sunny, more humid. Slight chance of thunder. High: near 80

Sunday: Sticky with intervals of sun, warmer. T-storms most likely far north. High: 82

Monday (Labor Day): Still warm for early September. Hazy sun, humid with a few strong T-storms nearby. High: 85

News of a little weekend frost

7 am temperatures predicted for Sunday morning, showing a large area of 30s from Lake Mille Lacs to Taylor's Falls, northward to Duluth, Tower and Embarrass, where a rare, late-August frost can't be ruled out. Chilly weather extends as far south as Iowa, where more 30s can't be ruled out. The "urban heat island" (more industry, concrete/asphalt) should keep temperatures in the Twin Cities metro area no cooler than 40-43 degrees.

I was debating one more mad dash up to the cabin on Pelican Lake, one more chance to check out "Elvis" at Breezy Point (I swear it really might be the real Elvis swooning out there on the dock). But the more I look at the weather maps the more inclined I am to stay put, loiter here in the metro, maybe check out the State Fair while it's cool, comfortable, more like late September.

Yes, I'll say it again: if you like your State Fair strolls cool and pleasant, with just a hint of an autumnal bite in the air, a dash of crisp, crackling and cool, you'll enjoy this upcoming weekend. You may even need a light jacket or sweatshirt - morning temperatures will hold in the 50s, reluctantly reaching the 60s by afternoon. It still looks like Sunday will be the nicer day of the weekend with more sun and less wind, high temperatures peaking in the mid to upper 60s.

We will see a nice warming trend next week, temperatures recovering to near 80 by midweek, even a chance of some low 80s for Labor Day weekend. Long-range guidance would have you believe we'll see a run of 80s, even a few 90s (!) the second full week of September. I know - very odd. With the exception of a fleeting shower later today, again next Wednesday, it's a basically dry forecast for the next 7-10 days. If you need an extended dry spell for yard work, field work, construction, painting - whatever - take advantage of this relatively quiet spell. No downpours, no freakish EF0 tornadoes hovering over downtown - yes, I think we've seen our excitement for the month.

Sunday F-F-Frost? I know, it's way too early. We're barely two months past the Summer Solstice! How 'bout a little mercy? Well, I'm afraid we have many of the ingredients necessary for a late August frost - a fresh transfusion of dry, Canadian air, a bubble of high pressure directly above Minnesota, resulting in little or no wind at ground-level by Sunday morning.

Some of the coldest nooks and crannies of northern Minnesota (and northwest Wisconsin) could experience a brief frost - from Tower to Sandstone, Hinckley and Hayward, WI. I want to stress that MOST of the us will not see a frost, but I have a feeling that some of the coldest nooks and crannies up north are going to come within 2-3 degrees of freezing Sunday morning. That said, by late afternoon those same towns will be more than 30 degrees warmer, with highs in the 60s. Good grief - we just careen, ricochet, from one extreme to the next.

The arrival of this surge of sweatshirt-worthy Canadian chill will set off more clouds today, especially by afternoon, and a fleeting shower is possible, but instability and moisture is marginal for any thundershower activity. If you're heading out to the State Fair I wouldn't worry too much - just make sure you can duck into a building (preferably one with heart-healthy food) if the sky opens up for 30 minutes or so.

WRF/NMM Model showing predicted rainfall later today, from 1 pm to 7 pm. A southbound cool front will spark a few instability showers, even a clap of thunder - nothing terribly heavy or severe is expected right now.

Drought Monitor, latest update. Conditions are improving with our recent heavy/regular rains. Last week 14.4% of Minnesota was suffering through a moderate drought. Now that number is down to 7.5% of the state. The region of extreme drought that was showing up north/east of St. Paul, in Chisago county, has disappeared, thanks to recent downpours. Even so, half the state is still too dry, and I don't see any significant rain looking out the next week to 10 days.

Rainfall Statistics for August

Twin Cities: 6.35" (2.9" wetter than average) Temperatures for the month running half a degree cooler than average


St. Cloud: 5.08" (1.77 wetter than average). Temperatures for the month running .7 degrees cooler than average

Paul's Outlook for greater St. Cloud

Today: Mostly cloudy with a passing shower or sprinkle, turning breezy and cooler. Winds: NW 10-15. High: 67

Tonight: Gradual clearing, bordering on chilly. Low: 47

Saturday: Feels like late September. More clouds than sun, cool breeze. Winds: N 10-20. High: 65

Saturday night: Clear with near-record cold. Patchy frost possible from Lake Mille Lacs to the Brainerd lakes area. Low: 38

Sunday: Bright sun, light winds, temperatures recover quickly. High: 68

Monday: Sunny and milder. High: 75

Tuesday: Warm sun, feels like summer again. High: 78

Wednesday: Sun fades behind increasing clouds, chance of a shower. High: 77

Thursday: Mix of clouds and sun. High: 76

Warming into the upper 70s/low 80s for the Labor Day weekend with a very slight risk of widely scattered T-storms. Right now MOST of the holiday weekend looks dry, warm and lake-worthy.


"The two cities were separated only by a thin well-bridged river; their tails curling over the banks met and mingled, and at the juncture, under the jealous eye of each, lay, every fall, the State Fair. Because of its advantageous position, and because of the agricultural eminence of the state, the fair was one of the most magnificent in America. There were immense exhibits of grain, livestock and farming machinery; there were horse races and automobile races and, lately, aeroplanes that really left the ground; there was a tumultuous Midway with Coney Island thrillers to whirl you through space..."

- From A Night at the Fair, by F. Scott Fitzgerald, 1921.


Minnesota State Fair Statistics
(thanks to Pete Boulay at the MN State Climate Office)

Hottest: August 24, 2003: 97 F.

Coldest: September 1, 1974: 36 F.

Wettest: 1977 (9.48" rain reported during the length of the fair)

Closest tornado: June 14, 1981. The "Har Mar Tornado" passed 1 mile north of the fairgrounds.

Strongest winds: August 20, 1904 (wind gusted to 110 mph. at the St. Paul Weather Bureau before the anemometer blew away! Winds would have been comparable at the state fairgrounds).

A Spectacular Fair Opener

Flame-on-a-Stick. O.K. This is the ONLY thing I haven't tried at the Minnesota State Fair. Hey, how did that guy get my favorite sport coat?

Better than fair. There's something to be said for getting a jump on the Minnesota State Fair, especially when the forecast is as promising as it is today. The weather should be close to idea, temperatures rising through the 70s (peaking at 77 around 4 pm). Factor in a light puff of a northeasterly breeze (under 8 mph) and dew points in the mid 50s and you have a PERFECT day for strolling, pointing, people-watching and heart-healthy food-on-a-stick. If you head out today you will NOT be disappointed.

I saw this on TwitPic last night. These must be Conan's writers, snapping pictures of the amazing white chocolate bust shipped in by the Minnesota State Fair. I'm getting hungry. You?




Here we are, focused on "Danny", a tropical storm on its way toward becoming a minimal hurricane. Then again, the term "minimal hurricane" sounds a bit odd. ANY hurricane is a pretty big deal, for the record. Danny is still rather disorganized (see the satellite image below) but as the center, the core of the storm passes over the warm waters of the Gulf Stream rapid strengthening is likely. Danny will probably become a Category 1 hurricane by Friday, threatening the eastern seaboard and much of New England by Saturday as it races right up the coast. It will be a close call, a strong Bermuda high forcing Danny to take a westerly track, much farther west than Bill did last week. Danny may impact 60-80 million Americans living from the Outer Banks of North Carolina northward to the Chesapeake Bay, Washington D.C., Baltimore, Philadelphia, New York City, and a huge swath of New England from coastal Connecticut to Boston and Cape Cod may be impacted by at least tropical storm-force winds of 40 mph+. My hunch is that Danny will make a mess of travel weekend travel plans from Cape Hateras, North Carolina to Portland, Maine. If you're heading in that direction you'll want to stay up on the very latest forecast.

WRF/NMM Forecast for 1 pm Saturday, showing the center of Hurricane Danny just east of Ocean City, Maryland, racing north at 30-40 mph.

Thor, the Blizzard! Naming blizzards and major winter storms? Don't laugh. The Grand Forks Herald newspaper named major winter storms after famous local politicians and hockey stars in the 1970s! They're no longer doing this, but the whole idea was to a). make storms easier to remember, and b). sell newspapers! Not a bad little gimmick. Think it would work today, in Minnesota? Somehow I think it would end badly...

More art than science. NHC (National Hurricane Center) meteorologists have a lot of challenges in front of them, the track of a given hurricane, and the expected intensity. They use scores of computer models, focusing on a handful that tend to work best in a tropical environment. History shows that forecasters consistently do a much better job predicting the track of a hurricane than the expected intensity, with depends on a myriad of factors, including wind shear aloft and ocean water temperatures below. That's where the "art" comes in. The biggest fear, what keeps meteorologists up at night? This scenario: a minimal, Category 1 hurricane approaches the coast. Being a "minor" storm most coastal residents decide to ride out the storm - stay put. But the next morning meteorologists are shocked to discover that the hurricane has exploded into a Category 4 storm, a BEAST, with sustained winds of 140 mph and gusts to 165! Millions of coastal residents are threatened, but now there's just not enough time for all of them to reach safety before landfall. This, truly, is the nightmare scenario, and it almost happened, in 1991. More on that in tomorrow's weather column (thanks for tuning in, btw!)


Projected path of "Danny", expected to become a hurricane by 8 pm Friday before racing right up the east coast. For the very latest information on Danny from the NHC, the National Hurricane Center, click here.

Weather Headlines

* Go while the 'gettin is good! Today: nicest day of the next 3 days. Light winds, low humidity, ample sunshine.

* Friday puddles. Next cool front arrives with a couple hours of showers tomorrow, latest NAM model prints out .13" of rain (best chance PM hours).

* Saturday sweatshirts? If you're heading out to the fair early Saturday you may need a light jacket or sweatshirt, temperatures will be in the 50s much of the morning, reaching mid/upper 60s by late afternoon. Saturday is the coolest day in sight.

* Sunday smiles. As the center of high pressure drifts right over Minnesota Sunday winds will ease, with enough sun for low 70s. Sunday still appears to be the nicer day of the weekend.

* Sweating out Labor Day. Long-range GFS guidance is hinting (strongly) at 80s returning the end of next week and the first weekend of September. If you like your state fairs hot and sweaty, you'll find plenty of like about the Labor Day weekend.

Paul's Outlook for greater St. Cloud

Today: Plenty of sunshine, low humidity, light winds. Winds: W/SW 5-15. High: 78

Tonight: Partly cloudy, showers far northern MN. Low: 55

Friday: Clouds increase, few showers likely by afternoon. Cooler. High: 72

Saturday: More clouds than sun, cooler than average. High: 67

Sunday: Bright sun, less wind - nicer day of the weekend. High: 71

Monday: Sunny and mild. High: 73

Tuesday: Warm sun, closer to "average". High: 75

Wednesday: Mix of clouds and sunshine, warming up nicely. High: 76

Too much of a good (sunny) thing...


Yesterday I recorded my 4:00+ shows for sctimes.com, smiling, pointing, explaining, with what appeared to be a giant FLY on my left cheek. I'm happy to report it was not a persistent bug or giant tick, I'm happy to report. It was a wound, the aftermath of a biopsy performed on my face Monday. Men can be especially stubborn, no doubt - for weeks my dear wife has been imploring me to visit my friendly dermatologist - she was worried about a persistent red blotch, a pimple-like imperfection that didn't seem to want to go away. I know, TMI....sorry about that. The only reason I mention this is, well, twofold:

a). to defend my personal hygiene habits, and more importantly...

b). encourage you to take the sun seriously, especially if you're fair-skinned, work outside, or have a history of skin cancer in your family. Get into the habit of putting on (a little) sunscreen EVERY day!

Melanoma is no laughing matter. I'll know the results of my biopsy Monday, when I go in to get my stitches out. At that time I may work up the nerve to ask Dr. Wire why the stitches he put in are BLUE. I'm walking around with what looks like blue fishing line sticking out of my left cheek.


Tuesday got off to a dark, thundery start, mainly south of St. Cloud - over the southern third of Minnesota: swarms of showers and thunderstorms tracked from west to east. While St. Cloud only picked up .10" of rain MSP International Airport saw .53". The new Drought Monitor comes out tomorrow and I expect to see significant improvement statewide. Chances are we won't have any extreme drought, maybe no severe drought either - but I have a hunch moderate drought will hang on over parts of central and east central Minnesota. That said, there is NO QUESTION we are heading in the right direction; the worst of the drought is now behind us, and if this seasonably warm, thundery pattern hangs on another 1-2 months we may just recharge soil moisture and be in pretty good shape for 2010.

Doppler Radar Rainfall Estimates. The approach of a cooler front set off heavy showers and thunderstorms early Tuesday, the heaviest rains staying south of the Minnesota River, where some 1"+ amounts were reported. St. Cloud reported .10" of rain, but .53" fell at MSP International in Richfield, .67" at Eden Prairie, but only .26" fell at St. Paul and .28" at Crystal.

Today looks amazing. Go ahead and run a 3 hour errand for the boss, accidentally-on-purpose get lost driving back to the office. It should be one of the nicest days of summer with bright sun, light winds, low humidity. In a word: spectacular. Thursday should be nearly as nice with highs approaching 80, weather almost perfect for Day 1 of the Great Minnesota Get Together. Can you believe it's State Fair time? How the heck did THAT happen? The approach of a cooler front will set off more patchy mid and high level clouds Friday - by Saturday daytime highs hold in the 60s, with some nighttime lows dipping into the 40s up north. DEFINITELY take a jacket or sweatshirt up north. You'll thank yourself.

WRF/NMM Computer Prediction for Friday evening at 7 pm. Temperatures should be in the 70-74 range from St. Cloud to the Twin Cities, but check out the 50-degree readings over the MN Arrowhead. We'll get a taste of late September this weekend, but cool air will be fleeting - more warmth returns next week, in time for a very warm, sticky (thundery) Labor Day weekend.

After a chilly start early next week temperatures will quickly warm up next week, back into the 80s the latter half of next week - I wouldn't be shocked to see a 90 degree day in about a week or so. The best chance of showers/T-storms? Thursday night into Friday morning, but somewhat drier weather should return for the first weekend of September with highs in the 80s, a few degrees above average.

* No rain in the forecast for at least 8 days. Perfect stretch of weather for yardwork, fieldwork, construction. If you need an extended spell of dry weather take advantage of this!

* Warm weather hangs on into Thursday, cooler on Friday as winds shift to the north. Few rain showers brush MN Arrowhead Friday as cooler air arrives.

* Cool weekend at the MN State Fair with highs in the mid 60s (partly cloudy skies both days). Nighttime lows dip into the 40s, even in the metro area! If you like the State Fair cool & comfortable definitely plan on going THIS weekend.

* Warming up next week as winds swing around to the southwest, more 80s likely by the middle of next week.

* Growing thunder threat by Friday of next week.

* Labor Day Weather? Partly sunny, more humidity Saturday, Sunday and Monday, September 4-6, with widely scattered T-storms, highs in the 80s each day. It should feel more like the 4th of July than a classic Labor Day!

It's That Time of Year Again

Yep, it's about that time again... Itchy eyes, runny nose. I can almost time the Minnesota State Fair by my allergies. It never fails. I seem to always walk around the Fair looking like someone blew pepper in my face. It's terrible. Though, I'm not sure what's worse. Having a bad case of hay fever or overeating at the Fair... and we all know how that feels! We've all done it. I just seem to do it every year. So this year, maybe I'll lay off the corn on the cob... HMM, nope can't do that, it's too good. Well then, maybe it'll be the Pronto Pup... nope gotta have that. Bucket 'O' Fries - Geez, that's good too! See what I mean. It's hard not to walk away not bloated. I'm sure I'll find myself leaving the Fair again this year, muttering, I'll never do that again.


A Look Ahead

I'm not impressed by the forecast this weekend for the Twin Cities (MN State Fair in Falcon Heights): It appears to be breezy and cool with a spotty shower or two possible for Saturday. Sunday looks brighter and slightly warmer at this point, though, nothing like how I remember the Fair in recent years (hot and sticky).
(Side - I'll pull up some past State Fair weather data and share it tomorrow, stay tuned!)

In Other Weather News

Weather Headlines over the weekend included heavy surf along the East Coast from Hurricane Bill, which proved to be deadly along the Maine coastline. Unfortunately 2 lost their lives as a large wave washed them out to sea while they were spectating. Mother nature can be quite a spectacle, but there’s something to be said about the power of nature… we should always respect it.

The weather maps are fairly quiet around the nation today. Noteworthy storms may fire up across high plains this afternoon, but should only affect a tiny percentage of the people within the General T-Storm Risk issued by the Storm Prediction Center and if anything develops, it will only last a short while. Here’s the latest Watches and Warnings from SPC: www.spc.noaa.gov

One last note - Wildfires have been raging in Athens Greece, prompting massive evacuations for certain areas of the city. Reports on Sunday stated that these were the worst wildfires in the area since 2007, when 70 people were killed. Take a look at this amazing (high resolution satellite NOAA image from 22,500 miles above the earth’s surface):athens-smokeI’ve added red dots (the larger one depicts Athens) to show where the fires are and I’ve added yellow lines to define the smoke plumes.

Betting on a warm, quiet, drama-free week

Hurricane Bill, during headier times last week, when the storm was a "category 3" affair with sustained winds near 135 mph. Notice the fact that even last week, when the storm was "healthier", the cloud bands around the calm eye are not perfectly symmetric - they're skewed to the east/right side of the storm, the result of considerable wind shear aloft, which may be another sign of El Nino, a warming of Pacific Ocean water now well underway. That would tend to mean a reduced hurricane risk for the USA in the weeks ahead. Hurricane season peaks on September 11, by the way. That's the date a hurricane is most likely to strike the east coast of the U.S.
Minnesota State Data. Click here to go right to this NWS site, which is a great place to find specific climate data, warning information, or future forecast specifics, for any corner of the state!

So much data, so little wisdom. Is it just me or are you gagging on information, but finding it harder than ever to determine what it really means, where is the analysis, perspective, the background I need to make sense of all this craziness? Growing up, a child of the 70s, none of us could have anticipated the Internet Age, with it's seemingly infinite choices, information-on-demand, Google and Wikipedia, and a million other useful digital destinations at the tip of our fingers. Today it seems we're drowning in a roiling, raging sea of links, blogs, YouTube video clips, overwhelmed with texting, e-mail, voice mail, snail mail, increasingly paranoid about whether we're Twittering appropriately or updating our Facebook often enough. All this while playing News Director. Now WE get to choose what our news stream looks like, when and where we consume the information we think we care about.

In 1974 it was a lot tougher trying to solve the weather riddle. We could watch the local TV weather report, sure, and there were maybe 3-4 reliable sources of forecasts on the radio. That, and a weather map in the newspaper. To see the raw weather maps I would drive 20 miles to a local community college for a look at the LFM, the Limited Fine Mesh computer model, the one and ONLY computer model we had to base our forecasts on. Today there are scores of weather models; some work better than others in certain scenarios. The truth remains: the most accurate weather forecasts over time, rely on a mix of man and machine. Computer models are great, but meteorologists still have to step in and decipher the raw computer output, and try to determine when the computer is full of bunk and better ignored.

Today forecast accuracy improves roughly 1%/year, the 3-5 forecast accuracy is as good as the 48 hour forecast was in 1975. The amount of warning for an average tornado has more than doubled since then, from 6 to nearly 15 minutes. Now weather satellites document and scrutinize every hurricane wobble - giving coastal residents an average of 2-4 DAYS to get to higher ground. I'd like to believe that our technology has improved to the point where the Armistice Day Blizzard would not claim 80 Minnesota lives ever again; next time we'd KNOW that temperatures would fall from the 60s into the teens in a matter of hours.

Today's would-be meteorologist, weather-enthusiast, geek, fanatic (!) has a staggering wealth of data to choose from. Everyone has become their own armchair meteorologist, right? Everyone has a pretty good basic concept of radar and what a satellite image is. Farmer and pilots have always been skilled weather prognosticators, but I acknowledge that ALL Minnesotans are, by nature - by necessity - weatherwise beyond their years. We live an age of INSTANT-ON. Tell me NOW. Don't make me wait! That's why newspapers and magazines are folding and local TV stations are gutting shows and firing staff - far fewer people are watching the news; people are getting news on their own schedule, tailored for what they care about. "I don't need no 'stinkin News Director telling me what's leading the news - I will decide what leads MY news!

It's all about technology, taking advantage of this always-on, interactive, personalized platform. It's no longer a SPEECH. No, now it's a CONVERSATION. People, all of us, want to be a part of the process, we want our voice to be heard. Don't ram stuff down our throats - talk TO us, talk WITH us, not AT US! That's the refrain, and now the democratization of information with Apple Apps, e-mails bringing my favorite topics to me 24/7, podcasts that automatically update while I'm sleeping, favorite bookmarks from sources I trust. It's funny, TV stations are rerunning their news on their web sites, even specific stories, allowing people to comment. Two to three years from now that's going to be so outdated, a relic of the 90s. It reminds me a little of the late 1940s, when TV was overtaking radio as the #1 source of entertainment and information. At first clueless TV executives slapped favorite radio shows onto TV and patted themselves on the back. Then, a few years later, some brainiac had an idea. "Hey, let's take full advantage of this new medium and create shows with MOVING PICTURES as well as audio!" Fast forward to Archie Bunker and Simon Cowell.

I don't pretend to have the answers, but we are all in a very difficult, transformational period, where one era is ending, a new one beginning, and the transition from one to the other is hardly seamless and without pain. It's been wrenching. But something better is coming, a new always-on, interactive, personalized system that will allow you to watch whatever you want to see, on any device you want to watch it - hopefully with only the commercial messages you want to see, stuff that you're potentially interested in. Everything will be On-Demand, tailored for you. Instead of warning 80 counties in Minnesota of a tornado, just the handful of neighborhoods actually in the path will see an (optional) message warning them of a twister.

The idea of everyone watching the same thing, at the same time, is on it's last legs. With the exception of sporting events, Olympics, Superbowls, etc everyone will have their own personal streams, always updating, always customized, taking full advantage of high-speed Internet spectrum. I honestly believe that's where we're going. Later this year Apple will release a new tablet that will be another big step on the way to personalized news/advertising. It's going to be a wild ride, no question. We're placing some big bets with WeatherNation and Singular Logic (our attempt to reinvent advertising by allowing YOU to choose the categories of ads you're willing to watch to keep content free). You shouldn't have to watch Cialis ads unless you WANT to, unless you NEED to. The age of One-Size-Fits-All is so 1983. It's about to get very, very interesting out there...

I have to laugh. Rupert Murdoch honestly believes he can charge consumers to read his newspapers, and he's trying to get other newspaper publishers to do the same thing: set up pay walls around his news stories currently sloshing around the Internet. Call me crazy, but I think it's a little like trying to put the toothpaste back into the tube. Good luck with that. I'm betting (along with some very smart people I'm working with) that the vast majority of Americans and people worldwide will NOT want to pay for news/information, no matter how good it is, now that they've been getting it for free for so long. I think there's a much better chance of paying for all this news, entertainment and information by personalizing the news and the commercial messages to reflect each consumer. No more one-size-fits-all. Time will tell, but that old adage, "may you live in interesting times" rings true. Does it ever. Remember, this recession/media implosion is a threat, and an opportunity.

Hope you soaked up a wondrous Sunday; the mercury peaked at 78 in St. Cloud, but I saw 81 at Redwood Falls, Benson and Faribault, 84 at Canby. Today should be a few degrees warmer as a south/southwest wind continues to blow

El Uh Oh. The equatorial Pacific is warming - what can POSSIBLY go wrong? This is the latest sea surface temperature graphic, showing water temperatures as much as 2-4 degrees (F) warmer than average off the coast of Central America and Ecuador. Approximately 2 out of 3 El Nino patterns result in a "split flow" later in the winter, one that whips up more storms from southern California across the southern USA, but a milder, more westerly wind flow for much of the nation. Based on El Nino alone I'd be tempted to predict a milder upcoming winter.

But it's not that simple. The sun is still (amazingly) quiet - no sunspots - and for some reason that seems to coincide with temporary temperature dips here on Planet Earth. The fact that there's no end to this quiet solar cycle would push me in the direction of an average, or colder than average winter. Bottom line: too early. To be fair to you (and myself) more data has to arrive. It's like judging a play from the first two acts.

Premature.

Weather Headlines

Can I lose the sweatshirt? Yes. A dry, seasonably warm week is on tap, the result of west to southwest jet stream steering winds 4-6 miles overhead. Daytime highs should flirt with 80 just about every day this week. Not too shabby considering the average high right now is 79.

Will I have to water the lawn? Yes. Probably. There is a slight chance of a passing shower or T-shower late Monday night or Tuesday morning ahead of a weak cool front. That's pretty much it for the entire week!

Weather Drama? No. This week should be tornado-free, no torrential rains, no wailing sirens, no red-faced meteorologists ("how - exactly - do you miss a tornado RIGHT OVER DOWNTOWN MINNEAPOLIS?")

Weekend Prognosis: Bet on Saturday. There should be enough sun for upper 70s to near 80. Clouds thicken Sunday with a growing chance of showers/storms.

A Fair Start? Yes, the weather will be fine for Day 1 of the fair on Thursday. Expect generous sunshine with a high around 80, dew points in the low to mid 50s will make it feel very comfortable!
Is it safe to look out into next week yet? Probably not, but here goes: cooler the first half of next week, highs in the 70s, even some 60s up north, but warming back up into the 80s, maybe even 90 degrees by Labor Day weekend, the first weekend of September.

Paul's Outlook for Greater St. Cloud

Today: Warm sunshine, windy, very nice - distractingly nice. Winds: South 15-30, gusty. High: 83

Tonight: Clouds increase, chance of a shower or T-shower towards daybreak. Low: 60

Tuesday: Sun reappears, a few degrees cooler (with less wind). High: 77

Wednesday: Mostly sunny and pleasant. High: near 80

Thursday: (Day 1 of the MN State Fair). Plenty of sun, warmer than average. High: 82

Friday: Partly cloudy, a bit more haze and humidity. High: 79

Saturday: Probably the nicer day of the weekend, mix of clouds and sun, dry. High: 78

Sunday: Unsettled, more clouds, few showers, possible thunder. High: 74

Monday: Breezy and noticeably cooler with a leftover shower possible. High: 71

Sunday lives up to its name

Weather Perfection. THAT'S what I'm talking about! I took this shot yesterday, a tired Saturday sun illuminating jet contrails which had spread out into high, thin cirrus clouds about 25,000 to 30,000 feet above the ground. It turns out we are having a subtle impact on weather every day. Jet contrails over busy airport corridors can keep afternoon temperatures 1-3 degrees cooler during the day, and a couple degrees warmer at night than they would be otherwise.

Saturday's high in St. Cloud: 74 degrees.


Enhanced IR Satellite. Hurricane Bill sweeps north, brushing Cape Cod and coastal New England with gale force winds and 10-15 foot seas. High pressure centered over eastern Iowa will turn Minnesota's winds around more to the south/southwest today, temperatures should be 5-6 degrees warmer than yesterday with a little more humidity in the air, but all in all another amazingly fine late August day!

Pure unmitigated weather bliss. Translation: really, really nice. I'm still dazed and amazed, smiling uncontrollably, hyperventilating after what may have been the most amazing Saturday of summer. Check that, yesterday may have been the best day of summer: virtually no wind, crisp humidity levels, unlimited visibility, lukewarm temperatures, even the mosquitoes seemed to back off out of respect for a postcard-perfect day - the result of a ridge of high pressure overhead: a dome of drying, sinking, slowly warming air directly above our (grateful) heads.

WRF/NMM (NAM) Model Prediction for 1 pm temperatures today. Note readings at or above 80 over roughly the western half of Minnesota. The farther west you go, the stronger the (southerly) breeze and the better the odds of cracking the 80 degree mark.

We're waking up to some 40s Sunday morning, a touch of fog in a few river valleys, an omen of what's to come in the weeks ahead. Temperatures will warm rapidly today as winds pick up from the south, reaching the 10-15 mph. range this afternoon as the mercury flirts with the 80 degree mark. Today's warming trend spills over into Monday with highs in the low to mid 80s, a dew point reaching the low 60s, meaning more noticeable levels of humidity in the air (expect a few complaints). An eastbound cool front sparks a spirited round of showers and T-storms Tuesday, followed by drier, sunnier weather by midweek.


The Great Minnesota Get Together. It's baaaack, the Minnesota State Fair, kicks off Thursday of this week (how did THAT happen?) If you hope to get out sooner rather than later you may just be in luck, weatherwise. Computer guidance is hinting at near-perfect weather for Thursday's grand opening: plenty of sun, highs from 80-82 with a comfortable dew point in the mid to upper 50s...probably dry. No stinking hot weather is in sight, in fact it may cool down noticeably early next week, highs in the 70s, even some 60s by Monday or Tuesday of next week. It's early, but Saturday appears to be the nicer, drier, warmer day of the weekend for the fair, or one more mad dash up to the cabin. The chance of showers/T-storms will increase during the day Sunday, one week from today.

Today's Outlook for the greater St. Cloud area

Today: Mostly sunny, breezy and warm - a fine summer day. Winds: South 10-15. High: 80

Tonight: Clear to party cloudy. Low: 58

Monday: Hazy sun, warmer - still dry. High: 83

Tuesday: Unsettled with a good chance of showers, few T-storms. High: 79

Wednesday: Sunshine most of the day, very pleasant. High: 81

Thursday: Mostly sunny, not too many complaints. High: 82

Friday: Partly cloudy, seasonably mild. High: 79

Saturday: Probably the sunnier, drier, nicer day of the weekend - fading sunshine. High: 78

Sunday: More clouds, showers and T-storms arrive. High: 74

A high pressure weekend


After a week of pure weather drama - soaking rains, fickle tornadoes, uncomfortably cool and gusty fronts sweeping out of Canada - it's nice to be able to kick back and predict a high-pressure weekend. Not high pressure as in stress, mind you. We're talking a bubble of high pressure, a bubble of mild, dry, clockwise rotating air - sinking and warming as it descends. This fair-weather-maker will linger into Monday morning, keeping skies sunny, dry and increasingly warm. 80 is possible Sunday afternoon, but likely Monday, out ahead of a weak cool front which may spark a fleeting shower or sprinkle by Monday afternoon.

WRF/NAM Model Output for 1 pm Sunday. Temperatures by midday Sunday should be flirting with 80 over roughly the western half of Minnesota, winds increasing from the southwest at 10-20 mph.

Weekend Weather Headlines

Precipitation: Dry both days, virtually no chance of rain.

Winds. Saturday: NE 5-15. Sunday: SE 5-15.

Rainfall: none expected.

Dew point: upper 40s Saturday, mid to upper 50s Sunday, the more humid day of the weekend.

4 Panel "NAM" Model Output for the weekend. A ridge of high pressure draped over Minnesota and Wisconsin will keep skies sunny, winds light, right through midday Monday. Meanwhile check out the eastern seaboard - Hurricane Bill will swipe Cape Cod and Martha's Vineyard by Sunday. President Obama and family is tentatively scheduled to vacation on Martha's Vineyard this weekend - my hunch is that Air Force One may remove the President, as a safety precaution, before the brunt of the storm passes just east of the Vineyard on Sunday. Although winds probably won't exceed 30 mph, surf as high as 10-15' is expected, bad news for vacationers arriving by ferry.

Putting a Real Dent in the Drought of '09. Check out the estimated rainfall amounts for the entire week (from August 14 - 21). The dark green regions picked up more than 4" of rain, roughly a 5-6 week allocation of precipitation. You can see a small region of 8"+ rainfall north of Taylor's Falls, the biggest soaking this past week was 30-60 miles north/east of St. Paul, ironically falling on the part of Minnesota suffering from "Extreme" drought conditions. Go figure.

Paul's Outlook for greater St. Cloud

Today: Mostly sunny and beautiful with light winds. Winds: NE 5-10. High: 74

Tonight: Clear and cool. Low: 49

Sunday: Bright sun, a bit more wind and humidity, warmer too. Winds: SE 10-15. High: near 80

Monday: Warm sun, feels like the Dog Days. High: 83

Tuesday: Clouds increase, growing risk of showers and T-storms. High: near 80

Wednesday: Sunny, turning breezy, cooler and less humid. High: 77

Thursday: Mostly sunny and very nice. High: 78

Friday: Sun fading behind increasing clouds. High: near 80

A (favorable) Change in the Weather


A Presidential Encounter with Bill? No, not that Bill. Mr. Clinton won't be anywhere near Martha's Vineyard this upcoming weekend, when the first family is scheduled to spend some quality vacation time on this small, exclusive island, accessible by ferry only, roughly 2 hours south of Boston. The only problem? A category 3-4 hurricane by the name of "Bill" is forecast to pass just 150-200 miles east of Cape Cod, Massachusetts over the weekend, perilously close to Martha's Vineyard. Talk about lousy timing. My hunch, gut (nausea?) is that the vacation may be called off due to the hurricane threat. We'll see (check below for the Sunday morning computer forecast and you'll have a better idea why I suspect the Obamas may be hanging out in D.C. this weekend).


A Change in the Weather. No kidding! July we couldn't buy a shower (or a warm front). Now it won't stop raining! So far, during the first 20 days of August, the Twin Cities metro area has been swamped with 5.7" of rain. That's 3" more than usual for the first 20 days of August! If this keeps up the drought may be drawing to a close sooner than anyone thought.

Thursday Rainfall Amounts

Twin Cities: .52"

St. Cloud: .34"

Duluth: .66"

Grand Marais: .97"

Alexandria: .71"

Rochester: .03"


Drought Monitor as of August 18, Wednesday, at 7 am. Keep in mind the VAST majority of the rain came after 7 am Wednesday. Many neighborhoods have picked up 2-3" of rain since then. I have no doubt that most of the metro is still in a moderate drought, but my hunch is that next week's Drought Monitor may ease the severe/extreme drought conditions most severe north/east of St. Paul. Some of these counties have been inundated by 4-7" of rain since Wednesday!

Doppler Radar Rainfall Estimates for Wednesday. Note the 4-6" amounts north/east of the metro in Chisago and Isanti Counties, and another region of very substantial rains from near Willmar westward to Milan.




EF0 Tornado that hit South Minneapolis at 2 pm Wednesday afternoon, captured on an iPhone by Kristin Clark from WeatherNation. The video sequence was taken from Kristin's 7th floor Uptown balcony overlooking the Minneapolis skyline. Even in this still image you can see the lowering, rotating wall cloud.


Check out this video from a security camera at east Lake and 4th Street. The pond at the center of the screen temporarily drains (!) and a tree in the upper right lands on a van. Watch carefully and you'll see an EF0 tornado pass right in front. Anyone walking in THAT parking lot would have had quite a story to tell!

Here is the latest damage update from the local National Weather Service office, confirming weak tornadoes in south Minneapolis and North Branch. Then again, the term "weak tornado" is something of an oxymoron, right up there with "jumbo shrimp", "airline food", and "Senate Intelligence Committee". It makes no sense. ANY tornado is a pretty big deal, an EF0 twister still capable of wind speeds anywhere from 65 to 95 mph. Thank God these were small tornadoes, or the death toll could have very significant, touching down in densely populated areas.

Tornado Factoid #1: Hennepin County has seen 8 large, violent tornadoes (F3 to F5 strength) since 1951, according to the National Weather Service and the MN State Climatology Office.

Tornado Factoid #2: Tom Clark, who took the video of the tornado on his daughter (Kristin's) iPhone Wednesday was also in the process of installing a home weather instrument from La Crosse Technology (a little housewarming gift for Kristin from yours truly). Tom had just finished getting this thing mounted on the wall when the tornado formed less than 1/2 mile away. At 1:58 pm the barometric pressure bottomed out at 29.57" of mercury, just as the tornado was forming nearby.

4 Panel (NAM) Weather Model through 7 am Saturday morning. The same storm that whipped up Wednesday's crazy tornado buffet and Thursday's foul, wind-whipped showers, will finally get an eastward nudge over the weekend. By Saturday morning high pressure is forecast to be sunning itself over Nebraska, setting the stage for an increasingly sunny and warm weekend for Minnesota.

Today won't win any awards for splendor or ambiance - any sun will quickly give way to scrappy, low-hanging clouds leaking light showers and afternoon sprinkles. Winds will blow from the northwest at 20 mph, it will be choppy on area lakes, afternoon "highs" stuck in the mid to upper 60s. But fear not. Under the heading "Good Timing" the storm that has tormented us with unpredictable tornadoes, but lavished us with wondrous, well-timed, SOAKING, million dollar rains will finally get out of Dodge, tracking east toward New England, setting the stage for an increasingly sunny, warm and pleasant weekend. Sunday still looks like the best day to be out on the lake with highs topping 80 under a sunny sky. But the entire weekend looks memorable, dry, with less wind - classic, beautiful late August weather for Minnesota and Wisconsin. Very few complaints are anticipated. A shower may drift into town Monday, followed by slight cooling next week, but no weather drama is shaping up. At least I hope not. Not sure my heart can take too many more weeks like this one!

GFS Computer Forecast for Sunday morning at 7 am. Check out "Bill", Hurricane Bill, just east of Cape Cod and Martha's Vineyard, where rumor has it the First Family will be trying to escape for a little relaxation and family time. At the very least the Obamas will probably experience moderate to heavy rain from some of the outer bands of Bill, gusts over 40 mph, and waves greater than 10-15 feet coming ashore near their vacation pad at "Blue Heron Farm" near Chilmark, which supposedly rents out for $50,000/week. I wonder if they bought insurance for their vacation?

Paul's Outlook for St. Cloud and vicinity

Today: Mostly cloudy, windy, still cooler than average. A few passing showers and sprinkles are likely, best chance around midday. Some late afternoon/evening clearing is likely. Winds: NW 15-25. High: 67

Tonight: Gradual clearing - cool. Low: 51

Saturday: Plenty of sun, dry - less wind. Winds: NW 5-15. High: 73

Sunday: Nicer day for the lake or pool. Bright sun, light winds. Winds: SW 5-10. High: 81

Monday: Sun gives way to increasing clouds, slight chance of a shower. High: 82

Tuesday: A mix of clouds and sun, still pleasant. High: 78

Wednesday: Plenty of sun, slightly cooler, but close to average for late August. High: 75

Thursday: Partly cloudy and warm. High: 78


The National Weather Service has put together a great page, summarizing meteorological conditions at the time of the tornadoes. Click here to see what they've put together.
