Plowable Snowfall on Tuesday - Numbing Start to December

27 F. high temperature yesterday in St. Cloud.
36 F. average high on November 20.
28 F. high on November 20, 2015.

November 21, 2001: Record highs are set in west and north central Minnesota, ranging from the upper fifties to lower sixties. Redwood Falls set their high with 68 degrees Fahrenheit and Little Falls had a high of 65 degrees.
November 21, 1980: On this date, around 28 thousand Canadian geese spent their nights on Silver Lake in Rochester.



Trending Colder, Stormier and Snowier

Job security. Hey, if the weather didn't change every once in a while I wouldn't have a business, and we wouldn't have anything to chat about. Murphy's little know 4th corollary states that "storms, given a choice, PREFER to come on major holidays."

Uncanny but true. For the same reason it rains (hard) on Saturdays and thunders during outdoor wedding ceremonies. Mother Nature has a wicked sense of humor.

No problems today, but a long fetch of moisture from the Gulf of Mexico squeezes out a few inches of wet, slushy snow Tuesday - mixing with sleet and freezing rain.

Surface temperatures should be close to 32F, so freeways may be wet/slushy, but this could be a plowable pile of sloppy snow from the Twin Cities on north by Tuesday night.

Flurries give way to slow clearing Wednesday with a dry sky for Thanksgiving Day. We may wake up to flurries Friday morning but I don't see major drama on the highways. Light snow may slush up a few roads Sunday, but models hint at a major storm the middle of next week; a mix changing to snow.

Old Man Winter is back and possibly making up for lost time.

ECMWF Snowfall Prediction. The "Euro" looks even more impressive with closer to 6-7" for much of the metro by Wednesday night. I wouldn't rule this out, but I still suspect a fair amount of melting-on-contact with surface temperatures at or just above 32F Tuesday midday and afternoon.

Big Model Spread. When the models are tightly grouped, solutions closely aligned, our confidence levels rise. Models predict anywhere from 2 to  5" of snow by Wednesday in the Twin Cities. Source: Iowa State.

Predicted Snowfall by Midday Saturday. Residents of the south can only gawk in wonder, but the snowfall treadmill is picking up in speed and intensity from the higher elevations of the Pacific Northwest to the Upper Midwest and New England, where the most impressive (10-18") amounts will pile up in the coming days.

Tracking Tuesday's Sloppy Mix. NOAA's forecast precipitation type product hints at a mix of snow, sleet, even some rain for the south metro and southern Minnesota. But much of Tuesday's precipitation may fall as wet snow, especially over the north metro. No problems on the highways today. Source: AerisWeather.

Boating Season Is Over. I hate to break it to you, but I think that's pretty much it for fishing and golfing for the next few months. ECMWF guidance shows daytime highs above freezing into early next week, which may help to keep freeways wet and slushy vs. icy. MSP Meteogram: WeatherBell.

Cold Start To December. A broad, closed area of low pressure temporarily stalled over southern Canada will rotate cold air into the USA during late November and the first week of December. Not exactly Nanook, but colder than average over the northern half of the USA.

What La Nina? I'm not buying it (yet) but NOAA's Climate Forecast System (CFSv2) model is still predicting a warmer than average December for much of the west and Upper Midwest;  colder from New England to the Gulf Coast. Source: WeatherBell.

January: Warm Anomaly Increases. The size and intensity of the (predicted) warm temperature anomaly increases in January, according to NOAA's CFSv2 climate model. It may be wishful thinking, but just  staring at the +12F temperature departure for the Dakotas and Minnesota is warming me up.

February Temperature Anomaly - Wow. Again, buyer beware - climate models are interesting to look at, sometimes they're even right. I'm looking at the trends month to month. In spite of a (weak) La Nina cool phase in the Pacific temperatures are forecast to run significantly warmer than average i n February, especially across the Upper Midwest. Interesting data point - check back in a few months to see if it verifies.



U.S. Launches Revolutionary Weather Satellite. The Washington Post has more clarity and background on what makes GOES-R a massive step forward for the science of meteorology: "...The “camera” instrument on GOES-R — called the Advanced — doubles the resolution of the current NOAA satellites. It can scan the whole hemisphere in five minutes, and if there’s a particularly dangerous weather pattern approaching, forecasters can scan a smaller region over the United States every 30 seconds. Sudden bursts of lightning could mean thunderstorms are becoming severe. So, GOES-R has a lightning mapper to continuously monitor and transmit all of the lightning strikes across North America and the surrounding oceans..."

What's It Like To Fly Into The Eye of a Hurricane? Here's an excerpt of a fascinating chronology of a Hurricane Hunter flight into "Matthew", courtesy of NOAA AOML: "...We started bouncing up and down at a much faster rate, much like a very intense wooden roller coaster, as I tried to contain my stomach from getting too upset. As we pounded through the eyewall and made it into the eye, what I saw and experienced was truly breathtaking; thick white clouds above and below as far as the eye could see as blue skies and ocean attempted to pierce through, the turbulence experienced just moments prior was quickly winding down, and a sense of calmness surrounded us as we entered the eye of Hurricane Matthew. I was so taken aback by the magnitude of what I was seeing that I almost forgot to do my job and immediately started taking pictures and videos of the eye..."

Beaver Creek World Cup Races Canceled Due To Lack of Snow. The Denver Post reports: "Men’s World Cup ski races set for Beaver Creek Dec. 2-4 have been cancelled because unseasonably warm temperatures delayed snow-making efforts. Organizers made the announcement Thursday even as the high country was being pounded by a snowstorm that caused Interstate 70 to be closed at times. “Although we have now seen a positive change in the weather and forecast, there is not enough time between today and the first training runs to prepare and fine-tune a full downhill course and finish area,” said Doug Lovell, chief operating officer of Beaver Creek resort..."

The Heat Is On. It's been the warmest year on record, to date, for the Carolinas; 4th warmest since 1872 for Minnesota and New York; 6th warmest for Colorado and Wisconsin. It was also a record warm start to November for much of the USA, reports WXshift: "...And the warmth is continuing into November. According to the Southeast Regional Climate Center, several locations in the Northern Plains, Northern Rockies, and West Coast are having their warmest November on record so far. This includes cities as diverse Milwaukee; Bismarck, N.D.; Rapid City, S.D.; Salt Lake City; Boise, Idaho; Seattle; Los Angeles, and San Diego. Many locations had long-held records fall this week. On Nov. 16 alone, Oklahoma saw its latest 90°F reading (the previous record had been Nov. 8), Lincoln, Neb., had its latest 80°F day on record, and Fort Collins, Colo., hit 79°F, tying its all-time record high for November. On the same day, the temperature in Reno, Nev., fell below freezing for the first time this season -- that was the latest first freeze of the fall on record. The previous record was Nov. 4..."

102 Million Dead California Trees "Unprecedented In Our Modern History" Officials Say. Here's the intro to a sobering story at the L.A. Times: "The number of dead trees in California’s drought-stricken forests has risen dramatically to more than 102 million in what officials described as an unparalleled ecological disaster that heightens the danger of massive wildfires and damaging erosion. Officials said they were alarmed by the increase in dead trees, which they estimated to have risen by 36 million since the government’s last survey in May. The U.S. Forest Service, which performs such surveys of forest land, said Friday that 62 million trees have died this year alone..."

Earthquakes: Reckoning With The Big One in California - And It Just Got Bigger. Here's a good summary of a recent study at The Wall Street Journal: "...For years, scientists believed the mighty San Andreas—the 800-mile-long fault running the length of California where the Pacific and North American plates meet—could only rupture in isolated sections. But a recent study by federal, state and academic researchers showed that much of the fault could unzip all at once, unleashing a rare, singular catastrophe. Now, insurers have used that research to come up with a new analysis of the damage that could be caused by statewide break of the San Andreas..."

A Golden Age For Television Series - But Can It Last? Here's a snippet of an interesting story at The Washington Post: "...But the wild spending is stoking fears about whether or when TV’s financial bubble might burst. The glut of scripted dramas and comedies has dramatically boosted budgets, but it has not solved the industry’s most dire dilemma: The lack of a functioning business model for a new TV era. “The overall television ecosystem can’t sustain this,” said Eric Schrier, president of original programming for FX Networks, home of Emmy winners such as “The Americans” and “The People v. O.J. Simpson: American Crime Story.” “There are networks [investing] in original programming and scripted TV that are trying to justify their existence by being in that business,” Schrier added. “And as the consumer can’t consume all this content, the strong will survive and the weak will not be able to exist...”

We Really Need To Figure Out How To Stop a Killer Asteroid, Scientists Say. Here's a clip from The Washington Post: "...NASA has discovered some 17,000 potentially hazardous near-Earth objects, but none of them is projected to come close to Earth in the next hundred years. No human that we know of has been killed by a meteorite or the effects of an impact, and the likelihood that this could happen to any of us is very, very slim. The chance of an impact big enough to destroy our planet is even smaller. Remember that Earth has suffered only one mass extinction-inducing impact that we know of in its 4.6 billion-year history, and even that asteroid didn't end life entirely. Our planet is pretty resilient. Still, plenty of researchers don't want to simply wait around and see what happens..."

Quit Social Media, Your Career May Depend On It. Are we distracting ourselves to death? Here's an excerpt from an interesting essay at The New York Times: "...The idea that if you engage in enough of this low-value activity, it will somehow add up to something of high value in your career is the same dubious alchemy that forms the core of most snake oil and flimflam in business. Professional success is hard, but it’s not complicated. The foundation to achievement and fulfillment, almost without exception, requires that you hone a useful craft and then apply it to things that people care about. This is a philosophy perhaps best summarized by the advice Steve Martin used to give aspiring entertainers: “Be so good they can’t ignore you.” If you do that, the rest will work itself out, regardless of the size of your Instagram following..."

How Social Media Broke Democracy. We are lost in our social media news consumption bubbles, and this makes it harder to empathize with others? Here's an excerpt of a thought-provoking essay from Tobias Rose-Stockwell at Medium: "...Facebook has stated that their mission is to make the world a more open and connected place. And they have, by anyone’s measure, connected more humans than any company in history. With this success, they have also created a tool that has allowed us to become more insulated in our own ideological bubbles than we ever have been before. Because of this lack of pluralism, we are systematically losing our ability to empathize. This is what we now see in the wider world — from Brexit to Trump to hyper-nationalistic movements worldwide. People globally no longer have the same incentives to find a shared understanding. This is not just dissatisfaction with globalization or the status quo. This is how we are changing our society by not seeing each other..."

Dancing in a Hurricane. Thomas Friedman explains our collective angst and paranoia in an Op-Ed at The New York Times: "...So no wonder many in the West feel unmoored. The two things that anchored them in the world — their community and their job — are feeling destabilized. They go to the grocery store and someone there speaks to them in a different language or is wearing a head covering. They go into the men’s room and there is someone next to them who looks to be of a different gender. They go to work and there’s now a robot sitting next to them who seems to be studying their job. I celebrate this diversity of people and ideas — but for many others they’ve come faster than they can adapt..." (Image: GE Reports)

Climate Stories

The Rockefeller Family Fund vs. Exxon.  Here's an excerpt of a long, fascinating and troubling story at The New York Review of Books: "Earlier this year our organization, the Rockefeller Family Fund (RFF), announced that it would divest its holdings in fossil fuel companies. We mean to do this gradually, but in a public statement we singled out ExxonMobil for immediate divestment because of its “morally reprehensible conduct.”1 For over a quarter-century the company tried to deceive policymakers and the public about the realities of climate change, protecting its profits at the cost of immense damage to life on this planet. Our criticism carries a certain historical irony. John D. Rockefeller founded Standard Oil, and ExxonMobil is Standard Oil’s largest direct descendant. In a sense we were turning against the company where most of the Rockefeller family’s wealth was created..."

America's TV Meteorologists: Symptoms of Climate Change Are Rampant, Undeniable. Here's an excerpt of an Op-Ed I wrote for the Washington Post's Capital Weather Gang: "...One snapshot in time doesn’t prove anything, but string these snapshots together into a longer-running movie and you start to see the outline of something larger in play. Imagine your favorite college football team running out onto the field, but all the players have a case of the flu. They suited up, but now they’re slow, groggy and sluggish, running the wrong routes, more prone to confusion and injury. Our atmosphere and oceans have a mild case of the flu — and symptoms are now showing up in the weather. I interviewed 11 of America’s premiere broadcast TV meteorologists, to hear their thoughts and stories of how a rapidly changing climate is affecting local weather patterns..."
