Snow on the way late Sunday into Monday – Winter Weather Advisory issued for parts of the Northland

Winter Weather Advisory has been issued for parts of east-central Minnesota and all of northwest Wisconsin for Sunday night and Monday.

Some cities included in the advisory are: Walker, Brainerd, Hill City, Aitkin, Hinckley, Moose Lake, Cloquet, Duluth, Superior, Bayfield, Ashland, Grantsburg, Minong, Shell Lake and Hayward.

Travel could be difficult due to the snow. Plan on slippery road conditions including for the Monday morning commute.

Here’s my preliminary snowfall forecast for Sunday night and Monday.

*A swath of 4 to 6 inches of snow in east-central Minnesota and northwest Wisconsin including the cities of Brainerd, Aitkin, Sandstone, Duluth, Two Harbors, Superior Bayfield, Ashland, Grantsburg and Hayward.

*2 to 4 inches of snow farther north, including Grand Rapids, Hibbing and Grand Marais.

*Snowfall amounts taper off to 1-2″ from Bigfork to Ely, and to less than an inch for International Falls.

Radar forecast valid from Noon Sunday to 7 PM Monday per 18z NAM-WRF model.

Snow spreads east/northeast into most of the Northland from late Sunday afternoon through Sunday evening with snow overnight. Snow tapers off from west to east during the day Monday.

Note: Lake enhanced snow is possible late Sunday night into Monday along the South Shore of Lake Superior with winds out of the north/northeast. There is a chance that some lake enhanced snow also occurs farther west into the Twin Ports for a few hours Sunday night/early Monday morning if winds become more NE than N.


One thing which will fuel our next snow event will be this temperature contrast which will be in place on Sunday.

…Weather Summary…

Strong warm air advection is well underway this afternoon with 4 PM 850mb temperatures of +2 to +6C over most of the Northland, unfortunately with so much snow on the ground and extensive cloudiness today highs were held in check, close to normal to slightly above normal for early December with temps in the mid 20s to around 30 degrees, but if there was less snow and more sun today, highs probably would have climbed well into the 40s.

Mostly cloudy skies will be found over the Northland tonight and Sunday. A cold front will drop SE out of the Northern Plains which may cause some patchy light mixed precipitation in parts of the Northland tonight and Sunday. Some patchy fog is also possible through Sunday morning.

It’ll be a mild night tonight with lows in the 20s and 30s, and will have a wide range in high temps on Sunday, ranging from the single digits and teens near the Borderland to the 30s in eastern Minnesota and northwest Wisconsin.

South winds tonight will shift to the north on Sunday with wind speeds of 10 to around 20 mph.

Snow is expected to spread E-NE into the Northland Sunday night due to an area of low pressure which is forecast to move east out of the Western High Plains. Snow should continue into Monday, but is forecast to end from W-E through the day.

Computer models are in good agreement with Sunday night’s system, but we could still see some changes in snowfall totals and where the axis of greatest snow amounts set up over the next 24 hours. Stay tuned.

After this early week snow event, cold arctic air pours into the upper Midwest with a frigid airmass over us for Tuesday, Wednesday and Thursday. High temps in the single digits below to single digits above zero with lows in the teens, 20s and 30s below are looking quite likely over the Northland during the middle of next week. Dangerously cold wind chills are also possible, ranging from around 30 below to 45 below.

Temperatures are forecast to modify later next week so this blast of bitter cold air shouldn’t stick around very long the way it looks now.
