A frigid and dry week ahead

Daytime highs will generally range from around 10 below to 5 above zero in northeast Minnesota and northwest Wisconsin on Monday, Tuesday and Wednesday while overnight lows will be in the teens, 20s and 30s below zero.

No widespread snows in our area this week, although there could be a few flurries at times, but that would be about it. Models diverge significantly starting later this week with the Canadian and Euro models going with a much snowier pattern in our area while the GFS model remains very dry.

  • Low of -24 F at the Duluth Airport on Sunday, February 7, 2021, this is the first -20 or colder temperature in Duluth since February 13, 2020, and this morning’s low of -24 degrees is the coldest temperature in Duluth since January 31, 2019 when the low reached -31 F.
  • No new record lows reported in the Northland Sunday morning (February 7, 2021) and it doesn’t look like will set any new record cold high temps for February 7 either, although all 5 climate stations in the Northland (Duluth, International Falls, Hibbing, Brainerd and Ashland) look to have a top 5 coldest high temperature on record today (February 7, 2021)

Widespread frigid temperatures across Alaska, Canada and into northern parts of the US today, pretty incredible how large of an area has subzero temperatures this afternoon.

-Wind Chill Warning in effect until Noon Tuesday including the cities of International Falls, Bigfork, Grand Rapids, Hibbing, Ely, Two Harbors, Isabella, Silver Bay and Grand Marais. Wind chills as low as 45 below zero.

The Great Lakes are acting as a heat/moisture source again today, and with a ton of arctic air moving over the still relatively ice-free lakes, we’re seeing widespread lake clouds and snow showers today for west or west-northwest favored snowbelts. Also of note are some mid/high level clouds streaming east out of western/southern Minnesota this afternoon (yellow outlined area on map) Should these clouds pass over and then linger in the Northland this may help keep temps ‘slightly’ warmer tonight compared to what we saw Sunday morning, but either way you slice it, another bitterly cold night is ahead, and even more likely if skies remain generally clear tonight.

GFS model continues to bring a lobe of the Polar Vortex (upper level low) on a southeast track into northern Minnesota and northern Wisconsin late this week/weekend (~February 12-14) however, there is quite a bit of uncertainty showing up in model guidance beginning later this week, as some models show the upper low setting up farther to the west, which then leads to slightly warmer temps for our area, and a potentially snowier weather pattern across the upper Midwest and in the Northland. Stay tuned.

12z GFS model 500mb forecast valid February 12-14, 2021.
