Light fluffy snow lingers in parts of the Northland tonight; more snow possible later this week followed by arctic air

  • January 2021 will end with an average monthly temp of ~7 degrees warmer than normal at Duluth, while precip for the month was ~0.40″ below normal. Snowfall this month was well below normal by ~10″. A complete climate report for the Northland for January 2021 will be issued on Monday.
  • Only 12 days with a subzero temperature so far this winter in Duluth. The normal from December 1 to January 31 is 24 subzero days, and the normal for the entire winter from December thru February is 35 subzero days. We have some work to do in February.
  • Some light snow and flurries will continue in parts of northeast Minnesota and northwest Wisconsin tonight but accumulations should be under an inch.
  • Dry weather is expected in our area Monday and Tuesday as temperatures will be above seasonal normals as we kick off February!

…Snow chances later this week…

Our next shot for some snow in the Northland comes later in the week (Wednesday night-early Friday time frame) at the moment this doesn’t look like it will be a major snow event for our area since the trough approaching from the west looks fairly progressive, but should this system slow down and dig more to the west/south, that would open up the possibility for a more significant snow event impacting parts of the Northland later this week.

…A blast of bitterly cold air possible next weekend…

Computer models are starting to come into agreement in showing what could be a shot of frigid arctic air for many of us around the February 6 thru 9 time frame.

High temperatures only in the single digits and teens below, with overnight lows in the teens, 20s and 30s below are possible over much of the Northland around February 6-9.

Shown below is the 500mb height anomaly forecast valid from February 6-8, 2021 per 12z European computer model.
