Another 1-2" This Evening (storm totals from 6-10", a few spots may pick up 12")

Winter Wonderland. How did expected snowfall amounts double in the span of 24 hours? Every storm is different, and this one was especially fickle, for a number of reasons. Usually a thick layer of cold air needs to be in place for a major snowfall. We didn't have that with this storm, temperatures aloft fairly close to freezing this morning. But the upward motion, the vertical velocities associated with this storm are unusually intense. Not only does this create moderate to heavy snow, but strong upward motion cools the column of air overhead, preventing a changeover to ice or rain, which would keep final amounts down. Saturday morning is still looked like the axis of heaviest snow would set up from near Alexandria and Willmar to Little Falls, Brainerd and the North Shore of Lake Superior. By afternoon models were shifting that axis from southwest-northeast, to a more west-east configuration, stretching from Willmar to the Twin Cities to Baldwin, WI. Yes, every weather scenario is fluid - this one surprised me a little. I realize the snow is a hardship, a bummer for many people. All it takes is one good fall on ice to ruin your winter (or worse). I get it. But you live in Minnesota - where snow is part of the landscape (some winters). If you don't like it, be patient - this too shall melt (although no time soon, certainly not before Christmas). No big thaws looking out 2 weeks. If you happen to like snow - congratulations. We all just won Minnesota's Snow Lotto.

For once.

* I expect another 1", maybe 2" in a few spots before the snow finally starts to taper off later this evening. Hopefully MnDOT will have roads in decent shape for the Monday morning commute, but with temperatures falling into single digits late expect a layer of glare ice under all that new snow. Yes, it will still be a slow commute tomorrow.

** thanks to my friend Heidi Rusch for the photo above, taken in front of her house in Minnetonka. Yes, it really is beautiful out there right now, with snow sticking (to everything - including my dog).

Snowfall Totals. Over 7" in Minneapolis, nearly 11" in Hugo and over 9" at Hutchinson as of 4:30 pm. The latest observed snowfall amounts are here, courtesy of the National Weather Service.

Updated Snowfall Reports. Click here to see an interactive map from the Twin Cities NWS with the latest snow totals - I'm seeing a lot of 9"+ reports around Minneapolis and St. Paul and the suburbs, a few reports over 10".

Snowy Resources. Here we go. The snow will pile up fairly rapidly today, coming in waves from west to east. I've included a few links so you can see the latest snowfall reports, Doppler radar images and road conditions. Be careful out there - conditions on area highways will go downhill as the day goes on; a potential for near-blizzard (white-out) conditions over central and southwestern Minnesota by afternoon as winds kick in behind this intensifying storm. Snow lovers will be in heaven. Commuters? Not so much.

Here's the latest on the Blizzard Warning, which is getting uncomfortably close to the Twin Cities, from the NWS:

...MAJOR WINTER STORM WILL CONTINUE TO IMPACT THE AREA THROUGH
THIS EVENING...

...BLIZZARD CONDITIONS EXPECTED ACROSS WESTERN MINNESOTA THIS
AFTERNOON AND EVENING...

.A BLIZZARD WARNING REMAINS IN EFFECT FOR MUCH OF WEST CENTRAL

CONSIDERABLE BLOWING AND DRIFTING SNOW WILL RESULT IN WHITEOUT
CONDITIONS MAKING TRAVEL NEARLY IMPOSSIBLE BY THIS AFTERNOON.
AREAS OF BLOWING AND DRIFTING SNOW ARE ALSO EXPECTED FARTHER
EAST...BUT LIGHTER WINDS PRECLUDE THE ISSUANCE OF A BLIZZARD

Latest Radar. NWS Doppler at 5:09 pm shows snow slowly tapering over southern Minnesota, another 1-2" possible in and around the metro before winding up as flurries after 7 or 8 pm. A few spots will be boasting a cool foot. For the latest radar image from Ham Weather click here.

Very Plowable. This storm may be crippling for parts of central and west central Minnesota, the result of near-blizzard conditions later today as winds increase. Metro? Plowable indeed, with anywhere from 5-10" of snow by 4 pm. The WSI RPM guidance above is from the 15z run, hinting at the best chance of 10" amounts on the east side of the MSP metro area, Taylors Falls to Stillwater and Hastings. Either way you look at it: a respectable pile of white. Model guidance above courtesy of WSI.
