Update: Bloomington 15″! Snowfall range 10″ to 20″ by Monday

Update 9:20pm:

UM Climate Guru and MPR colleague Dr. Mark Seeley sends word that we will likely break the all time state record for snowfall for February 20th!

With 15 inches of new snow at Bloomington, and much more to come I think it is safe to bet we will break the all-time state record for snowfall on February 20th ……that dates back to 1952 at Marshall when they received 16 inches. Observer at Hutchinson must be over 85 inches on the season so far…..

Mark

Thanks Mark… (I think!)

Latest MSP radar loop shows southern edge of snowfall lifting north toward the metro.

One of two things may happen by midnight.

1) The back edge of precip shuts off snowfall (at least temporarily) as it moves into the metro.

2) The northward progress of the back edge stops as the snow axis reaches the “pivot point” of the storm. If that happens the snow bands could stall right over the metro, especially the northern metro.

Either scenario may fit with the idea of snow tapering off a bit after midnight. Precip has already ended for now in much of southern Minnesota.

Latest snowfall totals here.

The latest “Minnesota Snow Blitz” has been a little finicky, but is delivering on the promise of a wind driven heavy snowfall “event.”

The storm was a little slow getting started, and produced some spotty snowfall coverage early. Since then, the storm has ramped up to full fury.

**Based on the storm’s progression I am sticking to my forecast of 10″ to 20″ storm total snowfall in the heavy snow band, which I expect to run from the Minnesota River Valley through the south metro to near Red Wing.

-Snowfall has now reached 10″ in some areas form the south metro to the Minnesota River.

Montevideo 10.5″

St. Peter 10″

Mankato 10″

Bloomington & Burnsville now 10″ to 13″

-The storm’s “deformation zone” is stretching out from east to west near the metro, and I still expect another 12 to 18 hours of accumulating snowfall, through noon Monday. The storm is about halfway over in many areas!

-The heaviest snowfall rates should come between now and midnight, as bands of heavy snowfall push up from southern Minnesota ahead of the storms upper air center, or “vorticity max.”

Modles still cranking out a 10″ to 18″ total snowfall range at MSP Airport.

-Howling winds will create blizzard conditions in much of southwest and west central Minnesota. Wind gusts over 60mph have been recorded in South Dakota!

Blizzard and winter storm warnings remain in effect into Monday!

Some people say never to tell Minnesotans not to drive; I am not one of those. Given the wind and intense snowfall rates and blowing snow it would be foolish to attempt travel tonight. There have literally been hundreds of accidents today, and dozens of injuries. Do not attempt travel tonight unless it absolutely urgent.

    Is there a reason burnsville is ending up in the high end of totals in most of the storms this year? Metorological or geographical? Or is it because I don’t own a good snowblower?

  • Aman

    I wonder if March going to be worse. Is March truly the snowiest month or is it just a local myth? Do you know which month holds that distinction in terms of average total volume and which for most days snowed (frequency)?
