Let the Melt Begin. Mid-Winter Rain This Weekend

Winter Weather Advisory Until 6am Tuesday
The same storm system responsible for major icing conditions across the central part of the country this weekend will continue to clip the southeastern part of the state through early Tuesday morning. A light ice glaze of ice and up to a slushy 1" of snow will be possible. 
...WINTER WEATHER ADVISORY REMAINS IN EFFECT UNTIL 6 AM CST TUESDAY...
* FREEZING RAIN AND SLEET INTO THIS EVENING WITH A CHANGEOVER TO SNOW DURING THE LATE EVENING. LIGHT FREEZING DRIZZLE POSSIBLE LATE IN THE NIGHT.
* ICE ACCUMULATIONS OF A GLAZE ARE EXPECTED ALONG WITH WET SNOW ACCUMULATIONS OF UP TO 1 INCH.
* LOOK FOR REDUCED VISIBILITIES AT TIMES.
* PLAN ON SLIPPERY ROAD CONDITIONS.
Simulated Radar
Here's the simulated radar through midday Tuesday, which shows a period of freezing rain and drizzle changing over to a wintry mix and snow through the night before moving out of the region by AM Tuesday. Travel conditions through the night will be poor across southeastern MN and into western WI as this wintry mix moves through.
Snow & Ice Potential
Here's the ice and snow potential thru the overnight hours as the storm system pushes through the southeastern part of the state. A light glaze of ice and up to 1" of snow may be possible, which could create difficult driving conditions through early Tuesday morning.
Visible Satellite Loop Monday
The same storm system that brought a crippling ice event over the Central U.S. over the weekend and early week time frame also brought clouds and areas of freezing rain across far southern MN and Wisconsin. Note that much of northern Minnesota stayed sunny as the storm just clipped our area.

Great Lakes Ships Arrive For Winter Layup
Thanks to the @NWSDuluth for capturing this image from the Lake Superior Maritime Visitor Center webcam, which shows the Roger Blough arriving early Monday morning as one of the last few ships to arrive in the Duluth port this season. The Paul R. Tregurtha arrives Monday after and is the last ship of the season to pass under the Aerial Lift Bridge this season as the Soo Locks  in Sault Ste. Marie Mich., close on Friday and won't reopen until March 25th.
 
Visible Satellite Sunday, January 15th
Sunday was an incredibly nice day across the Upper Midwest and Great Lakes region with mild temperatures and plenty of sun. Clear skies allowed for a fairly decent view of of the Great Lakes. Note the lack of ice cover across the Great Lakes and also note the snow cover on the ground across the region.
 
Great Lakes Ice Coverage
According to NOAA's GLERL, the Great Lakes ice coverage as of January 15th, 2017 was nearly 10%. Interestingly, at this time in 2015, nearly 34%

Let the Melt Begin. Mid-Winter Rain This Weekend
Not sure about you, but I actually like Winter. I am not a big fan of the face-numbing cold, but I like the snow! Give me a bunch of snow (minus the rotten commutes) and I would be a happy camper.
With that said, I feel a bit cheated. We've had a few bouts of snow and cold weather, but we've also had these weird warm spells. This has led to more wintry wintry mixed precipitation and rain events rather than just good old fashioned snow! What gives? If you thought thunderstorms and 1 inch rainfall tallies on Christmas Day was weird, well, the weirdness continues.
Weather maps look more March- like heading into the second half of January as the mercury tops 40 degrees later this week. Stillwater is host to Hockey Day in Minnesota this Saturday. The current forecast calls for a high temperature in the low/mid 40s with light rain. Come on man! Mother Nature should know better not to mess with Minnesota's outdoor hockey plans.
In meantime, enjoy the fact that we have feeling back in our extremities. We'll see what Feb. cooks up.

Weather Outlook For Tuesday
High temperatures on Tuesday will once again be warmer than average, but we really start to settle into our warm spell starting Tuesday. Note that much of the region, including the Twin Cities will likely warm into the low to mid 30s. This will begin the several day melting process. 
Weather Outlook For Tuesday
Winds will be very light on Tuesday and will also start turning more westerly/southwesterly late in the day. Later in the week, they will become more southerly, which will help to move temperatures up into the 40s!
 
Weather Outlook For Tuesday
After a cloudier day across southern MN on Monday, clouds will linger across southeastern MN through the day. Much of the rest of the state will break out into sunshine, which will continue to build into the region through Wednesday. 
 
Extended Temperature Outlook for Minneapolis
Here's the temperature outlook through January 25th, which shows a VERY mild trend heading into the week ahead with highs in the 30s and even 40s by next weekend! With several days above freezing, our snow pack will likely take a big hit... we may also have a fog concerns with melting snow and added moisture in the lower levels of the atmosphere.

___________________________________________________________________________________
6 to 10 Day Temperature Outlook
According to NOAA's CPC, the 8 to 14 day temperature outlook suggests warmer than average temperatures continuing across much of the Upper Midwest from January 26th to January 30th. With that said, extended models are suggesting temperatures returning to near normal levels by the end of the month. Looking ahead, there doesn't appear to be any major cold snaps brewing over the next couple of weeks.

Iowa Plow Cams
Did you know that IowaDOT equips their plow trucks with webcams? A network a frequently updating plowcams is a wonderful resource to see what conditions are like across the state. This was the view from near Waukon, IA from early Monday morning where travel was not advised, where freezing rain left area roadways covered in ice.

Major Ice Event Central US Wraps Up
Thanks to the National Weather Service out of Dodge City and Wichita, KS  for the pictures below, which shows the icing that took place there through the weekend. This was a crippling event for some folks in the Central Plains with widespread power outages and even some fatalities. Note that just 1/4" of ice can add 500 lbs. of weight to a span of power lines... this additional weight is what causes trees and power lines to come down. Many locations will be cleaning up and fixing power issues over the next several days if not weeks.

Ice Accumulations

Here's a look at the ice accumulations across the region from Saturday into Sunday. Note that there were two reports of 1" ice accumulations; one in Oklahoma and one in Nebraska!

 
Icing Potential Continues
The same storm system that caused all the issues in the Central U.S. this weekend will continue to create icing issues across parts of the Great Lakes and Northeast through midweek. Some spots across the Northern New England States will actually see a changover to snow, where up to 6" of snow maybe possible through Wednesday.

Icing Potential
Here's the icing potential  through midweek, which suggests light ice accumulations across parts of the Northeast. Although there won't be as much ice as what the Central U.S. saw this weekend, there will still be enough icing to create issues on area roads.

National Snow Coverage
According to NOAA's NOHRSC, the national snow coverage was nearly 50% as of Monday, January 16th. The images below compare the national snow cover from January 16th 2017 vs 2016. At this time last year, 43% of the nation was covered in snow. With temperatures expected to be as warm as they will be over the next several days, I expect a major snow melt across the eastern half of the nation over the next couple of weeks.
 

________________________________________________________________________

Highs From Average Thursday

Take a look at how much warmer than average much of the nation will be on Thursday. Just about everyone from the Front Range of the Rockies to the Eastern Seaboard will be at least 10F to near 20F above average!

National Temp Outlook
Take a look at the temperature anomaly through Tuesday, January 24th. Note that the Eastern half of the country looks to stay warmer than average through the entire time period. Late January appears to host colder than average weather across the western half of the country.  
 
Temperature Outlook
Here's the 8 to 14 day temperature outlook, which takes us into the end of January. Note that warmer than average temperatures continue across the Eastern U.S., while cold than average temperatures will move into the Western U.S.

Southern Severe Storms

Strong to severe storms were reported across parts of Texas on Sunday and Monday, including a few tornadoes. The red dots near Dallas, Waco and Houston were confirmed tornado reports that caused some damage.

Simulate Radar
Heres' the simulated radar from Tuesday to AM Wednesday, which shows ongoing showers and storms across parts of the Southern U.S.. There may even be a few isolated strong to severe storms near the Coastal Bend of Texas on Tuesday afternoon with gusty winds and an isolated, brief tornado being the main threat
 
 Severe Storm Threats
As the storm system slowly moves northeast through the Central U.S., strong to severe storms will also develop on the southern flank of this storm system. Below is the severe storm outlook for Tuesday. Note that there is a MARGINAL Risk of severe weather across the Coastal Bend of Texas, where gusty winds and an isolated tornado is possible.

_____________________________________________________________________________
Big Alaska Storm
Thanks to @NWSJuneau for sharing this satellite loop of the strong storm system impacting parts of southeast Alaska with strong winds, heavy rain and high elevation snowfall.
 
National Weather Outlook
Here's the national weather outlook through the middle part of the week, which shows the large storm system responsible for major icing the Central U.S. over the weekend finally moving out of the country by Wednesday. The trailing cold front will turn stationary across the Southern U.S. with lingering showers and storms and locally heavy rainfall. The next Pacific storm will move into the Western U.S. with widespread wintry weather and heavy rain along the coast. 
 
  Winter Weather Headlines
Winter weather headlines have been posted across parts of the Western U.S. in advance of another surge of Pacific moisture that will impact the region through midweek. Some locations will see sleet and ice, while other may see up to 12" of snow in the higher elevations.

7 Day Precipitation Forecast
According to NOAA's PC, the 7 day precipitation forecast suggests widespread 2" to 4"+ rainfall amounts across the Southern U.S.. Also note the heavy moisture moving back into the West U.S., especially along the West Coast. Some 6" to 12"+ liquid tallies can't be ruled out from northern California to western Oregon and western Washington. There may even be some 2" to 4" tallies across parts of southern California through early next week.
Snowfall Potential
The extended forecast calls for additional heavy moisture in the Western U.S. with heavy snow in the high elevations. Note that widespread heavy snow looks to fall from the Cascades to the Sierra Nevada Range to parts of the Rockies. The additional heavy snow in the Sierra Nevada Range is wonderful news for the upcoming water supply during the summer months for parts of California.

"Japan’s Biggest Coral Reef Devastated by Bleaching"
Almost three-quarters of Japan’s biggest coral reef has died, according to a report that blames its demise on rising sea temperatures caused by global warming. The Japanese environment ministry said that 70 percent of the Sekisei lagoon in Okinawa had been killed by a phenomenon known as bleaching. Bleaching occurs when unusually warm water causes coral to expel the algae living in their tissues, causing the coral to turn completely white. Unless water temperatures quickly return to normal, the coral eventually dies from lack of nutrition. The plight of the reef, located in Japan’s southernmost reaches, has become “extremely serious” in recent years, according to the ministry, whose survey of 35 locations in the lagoon last November and December found that 70.1% percent of the coral had died.

"Man Captures Northern Lights At 35,000 Feet After Finding Himself Sitting Alone On Flight"
With more and more of us flying on budget airlines, the idea of having space to spread out seems a little alien. Even extending your legs below the knee can prove troublesome. But now one man has shown the full potential of having a little more room to breathe, as he used an empty flight to set up his tripod and camera in the window seat and capture the Northern Lights.

Wintry Mix Monday Night. Very Mild Second Half of January

Wintry Mix Moves In Late Monday - AM Tuesday
The same storm system that brought significant icing across the Central U.S. over the weekend, will move into southern Minnesota late Monday - AM Tuesday. A wintry mix of freezing rain and snow will lead to difficult driving conditions Monday and AM Tuesday. The Winter Storm Watch that was in effect for parts of the region has been canceled due to the system not being quite as impressive as it looked before. With that said, up to 0.2" ice and up to 3" of snow may be possible in some locations as the storm pushes through. Here's an excerpt from the NWS Twin Cities regarding the system: 
"A wintry mix of freezing rain and snow will lead to slick roads and hazardous travel conditions Monday afternoon through Monday night. After that, it's a January thaw!"
Winter Weather Advisory
...A WINTRY MIX OF PRECIPITATION FOR FAR SOUTHERN MINNESOTA MONDAY AND MONDAY NIGHT...
A WINTER WEATHER ADVISORY HAS BEEN ISSUED FOR FAR SOUTHERN MINNESOTA FOR MONDAY AND MONDAY NIGHT. THE ADVISORY AREA IS ALONG AND SOUTH OF A LINE FROM ST. JAMES TO OWATONNA. THIS INCLUDES THE INTERSTATE 90 CORRIDOR. LIGHT FREEZING RAIN...SLEET AND SNOW WILL SPREAD INTO FAR SOUTHERN MINNESOTA MONDAY MORNING AND CONTINUE THROUGH MONDAY EVENING BEFORE DIMINISHING. ICE ACCUMULATIONS UP TO A TENTH OF AN INCH ARE POSSIBLE WITH SNOW ACCUMULATIONS UP TO 2 INCHES. THIS WILL LIKELY LEAD TO SLIPPERY TRAVEL CONDITIONS AND MOTORISTS ARE URGED TO SLOW DOWN AND ALLOW EXTRA TRAVEL TIME.
THE WINTER STORM WATCH FOR EAST CENTRAL AND SOUTH CENTRAL MINNESOTA HAS BEEN CANCELED.
...WINTER WEATHER ADVISORY IN EFFECT FROM 6 AM MONDAY TO 6 AM CST TUESDAY...
THE NATIONAL WEATHER SERVICE IN TWIN CITIES/CHANHASSEN HAS ISSUED A WINTER WEATHER ADVISORY FOR A WINTRY MIX OF SNOW...SLEET AND FREEZING RAIN...WHICH IS IN EFFECT FROM 6 AM MONDAY TO 6 AM CST TUESDAY. THE WINTER STORM WATCH IS NO LONGER IN EFFECT.
* SNOW...SLEET AND FREEZING RAIN ARE POSSIBLE FROM MONDAY MORNING THROUGH LATE MONDAY NIGHT.
* TIMING...THE WINTRY MIX WILL SPREAD INTO MONDAY MORNING BETWEEN 6 AM AND 9 AM.
* TOTAL WET SNOW ACCUMULATIONS OF UP TO 2 INCHES AND ICE ACCUMULATIONS UP TO A TENTH OF AN INCH ARE POSSIBLE.
* SIGNIFICANT REDUCTIONS IN VISIBILITY ARE POSSIBLE.
* THE ICE COULD RESULT IN DIFFICULT TRAVEL CONDITIONS ON MONDAY.
Simulated Radar
Here's the simulated radar as our next storm system surges north into the Upper Midwest Monday through AM Tuesday. Unfortunately, this is another storm that will bring a multitude of different precipitation types to the area with a mixture of rain, freezing rain, sleet and snow. Freezing rain will be a major travel concern where some locations could see up to 0.2' ice across parts of southern MN. There may also be some slushy snow accumulations (1" to 3") on the colder side of the storm as it lifts northeast through the early week time frame.

Wintry Mix Monday Night. January Thaw Begins
WOW! What a weekend! While some flock to sunny beaches in Mexico or Hawaii at this time of year, others flourish in the wintry Minnesota landscape. Whether you took to the trails or hit the pond, I hope you enjoyed it. Unfortunately, weather conditions sour for outdoor activities this week.
A devastating ice event will wrap up in the Central U.S. early this week. Widespread half to near three-quarter inch ice tallies have left parts of Kansas, Oklahoma and Nebraska in a real mess. That same storm grazes southern Minnesota with a light wintry mix late Monday into early Tuesday. An icy, slushy coating may be possible across parts of southern Minnesota just in time for the Tuesday morning commute.
After that, temperatures warm to well above average levels with highs in the 40s by the end of the week. Extended forecasts keep us at above average temps through much of the second half of the month. Our dwindling snow pack will likely become crusty over the next few days.
My kids will once again have a reason to blame me for the weather.

Snowfall & Ice Potential
As our next system approaches from the South on Monday and will be with us through early Tuesday. Snowfall accumulations look fairly light and slushy. There may be a narrow band of 1" to 2" with a few isolated 3" tallies. Unfortunately, this may also be accompanied by some icing (0.1" to 0.2")


Extended Temperature Outlook for Minneapolis
Here's the temperature outlook through January 23rd, which shows a VERY mild trend heading into the week ahead with highs in the 30s and even 40s by next weekend! With several days above freezing, our snow pack will likely take a big hit... we may also have a fog concerns with melting snow and added moisture in the lower levels of the atmosphere.

6 to 10 Day Temperature Outlook
According to NOAA's CPC, the 8 to 14 day temperature outlook suggests warmer than average temperatures continuing across much of the Upper Midwest from January 25th to January 29th. With that said, extended models are suggesting temperatures returning to near normal levels by the end of the month. Looking ahead, there doesn't appear to be any major cold snaps brewing over the next couple of weeks.

Highs From Average Thursday

Take a look at how much warmer than average much of the nation will be on Thursday. Just about everyone from the Front Range of the Rockies to the Eastern Seaboard will be at least 10F to near 20F above average!

Major Ice Event Central US
Thanks to the National Weather Service out of Dodge City and Wichita, KS  for the pictures below, which shows the icing that took place there through the weekend. This has been a crippling event for some folks in the Central Plains with widespread power outages and even some fatalities. Note that just 1/4" of ice can add 500 lbs. of weight to a span of power lines... this additional weight is what causes trees and power lines to come down. 

Ice Accumulations

Here's a look at the ice accumulations across the region from Saturday into Sunday. Note that there were two reports of 1" ice accumulations; one in Oklahoma and one in Nebraska!

 
Major Ice Event Central US
Take a look at all the winter weather headlines across the country and note the deep purple coloring from Kansas to Nebraska and Iowa. Those are Ice Storm warnings, where widespread 1/2" to 3/4" of ice or more could accumulate, which will continue to cause major travel impacts and even power outages. 
Icing Potential
Here's the icing potential in Kansas through Tuesday, which suggests more widespread 1/4" to 1/2" ice accumulations. This will cause more major travel issues and power outages. Kansas and Nebraksa will continue to see some of the worst icing this system has to offer, but widespread 1/4" to near 1/2" amounts across parts of northern Missouri and Iowa will still create major issues.
Simulate Radar
Heres' the simulated radar from AM Monday to PM Tuesday, which shows icy rains tapering across the Central Plains, while scattered showers and isolated strong storms continue across the Southern U.S. through early next week. 
 
Severe Storm Threats
As the storm system slowly moves northeast through the Central U.S., strong to severe storms will also develop on the southern flank of this storm system. Below are the severe storm outlooks for Monday and Tuesday. Note that a MARGINAL Risk of severe weather has been issued across parts of Lower Mississippi Valley for the potential of large hail and wind damage.


_____________________________________________________________________________
National Weather Outlook
Here's the national weather outlook through the middle part of the week, which shows the large storm system in the Central U.S. responsible for major icing concerns in the middle part of the country. The ice event will wrap up early in the week, but it will also bring widely scattered showers and storms to the Southern U.S. with isolated strong to severe storms and heavy rainfall. Also note the heavier moisture returning to the Pacific Northwest.
 
7 Day Precipitation Forecast
According to NOAA's PC, the 7 day precipitation forecast suggests widespread 1" to 3"+ rainfall amounts across the Southern U.S.. Also note the heavy moisture moving back into the West U.S., especially along the West Coast. Some 6" to 12"+ liquid tallies can't be ruled out from northern California to western Oregon and western Washington. There may even be some 1" to 2" tallies across parts of southern California through next weekend.
Snowfall Potential
The extended forecast calls for additional heavy moisture in the Western U.S. with heavy snow in the high elevations. Note that widespread heavy snow looks to fall from the Cascades to the Sierra Nevada Range to parts of the Rockies. The additional heavy snow in the Sierra Nevada Range is wonderful news for the upcoming water supply during the summer months for parts of California.

Sierra Snow
Take a look at the beautiful snow covered landscape from Yosemite National Park. This webcam from Half Dome shows how how incredibly beautiful the park can be in the winter when snow is present!
California Snow Comparison
California has been a significant drought over the last several years, but has made some improvements thanks to recent heavy precipitation. Take a look at the snow depth comparison from January 14th, 2014 vs 2017. Currently, FEET of snow is on the ground vs the very little snow pack that was on the ground in 2014 and in 2015.

"Climate change shows in shrinking Antarctic snows"
"Vast icy rock peaks tower above Argentina's Carlini research base in Antarctica. But scientists who have worked here for decades say the glaciers are less icy than they once were. For international experts stationed at the base, the frozen southern continent is a good gauge of climate change. "When I used to come to Antarctica in the 1990s, it never used to rain," said Rodolfo Sanchez, director of the Argentine Antarctic Institute (IAA). "Now it rains regularly—instead of snowing," he told AFP during an Argentine government visit to King George Island, off the tip of the western Antarctic peninsula. Scientists monitoring conditions at the base say the average temperature here has increased by 2.5 degrees Celsius (4.5 degrees Fahrenheit) over the past century."

"Beginning of the End of CA Drought, But What’s Next?"
"After a week of being walloped by major storms that have dumped copious rain and snow on the state, California is finally emerging from a deep, years-long drought. Ski resorts in the Sierra Nevada mountains are flush with snow, while key reservoirs have filled back up. On Thursday, the U.S. Drought Monitor erased all drought in Northern California from the map and dialed back the severity over the southern half of the state. There are, of course, still major deficits in groundwater levels that could take decades to replace and lingering ecological impacts, several experts said, but they agreed the situation had much improved. “I think overall we’ve gotten through this drought amazingly well,” Jay Lund, a water resources analyst at the University of California, Davis, said. One key concern going forward is how global warming may alter California’s notoriously boom-or-bust climate: Does it mean more, and more intense, drought? Will it strengthen the storms that bring the state most of its water? The current view is that it could mean both, effectively amping up the already wild variation the state experiences, though there is still uncertainty about some of the potential impacts of warming."

"Climate Change Is the World’s Biggest Risk, in 3 Charts"
The rise of the machines isn’t the biggest threat to humanity. It’s climate change, extreme weather and other environmental factors. The World Economic Forum surveyed 750 experts on what the most likely and impactful risks facing humanity are in 2017. In a report released Thursday, they ranked extreme weather as the most likely risk and the second-most impactful, trailing only the use of weapons of mass destruction. Climate change is responsible for driving an increase in the likelihood and intensity of extreme weather events, notably heat waves. Failing to adapt to or mitigate climate change and a host of other climate-connected risks including water and food crises and involuntary migration also rank in the top 10.
