A widespread but fairly short duration snow event is on the way for Monday night-Tuesday morning which could impact the Tuesday morning commute.
Here’s my snowfall forecast for Monday night-Tuesday.
*Highest totals of 3 to 6 inches along the North Shore including Two Harbors, Silver Bay, Isabella and Grand Marais.
*1 to 3 inch totals for the rest of the Northland.
A weak system will pass south of our area tonight, this system could bring a quick shot of light snow to parts of eastern Minnesota and northwest Wisconsin later this evening into early Monday morning, but snowfall totals should remain around an inch or less. Note: Snowfall totals of a half inch or less are possible in Duluth later tonight.
A stronger but quick moving system will affect the Northland Monday night into Tuesday bringing a period of widespread snow to the area. This snow will taper off from SW-NE on Tuesday.
Radar forecast below valid from 7 PM Sunday to 3 PM Tuesday.

Here’s a look at tonight’s system moving E/NE out of Nebraska per Goes-16 water vapor imagery. Most of the snow with this one stays south of the Twin Ports tonight.

Cold, arctic air bottled up over western Canada and the Northern Rockies with a large area of warmer than normal temperatures covering the southern/eastern US will lead to an active weather pattern across the Plains and Great Lakes this week as several low pressure systems track along the temperature gradient between the arctic air to the NW and the warmer air to the SE.

Low pressure moving east out of the Rockies could bring a widespread snow event to the Northland from Friday into Saturday, January 17-18.
So far model guidance has been in good agreement on the track of this system with potential for 4-6 inch or greater snow totals in northeast Minnesota and northwest Wisconsin late this week, but with this system still a few days away, the track of it could change which could decrease snow amounts in our area. Stay tuned.
