12z RGEM model. One thing that is helping to produce our snow is this large temperature gradient that is in place. Here’s the temperature forecast for Tuesday morning.
Note: Winter Weather Advisory remains in effect through Noon Tuesday for all of northeast Minnesota and northwest Wisconsin. Main precipitation type in northeast Minnesota will be snow, but in parts of northwest Wisconsin there could be a mix of snow, freezing rain, freezing drizzle or sleet tonight and Tuesday morning with a light glaze of ice accumulation possible especially around the Hayward Lakes area, possibly as far north as Ashland.

Link to Road Conditions
Pattern hasn’t changed at all today with a trough over the Rockies and a ridge over the southeast U.S. The upper Midwest remains in a moist SW flow aloft with waves of energy ejecting northeast out of the Rockies trough. A strong baroclinic zone remained in place today with late afternoon 850mb temperatures ranging from -20C in western North Dakota to +12C in central Missouri — Surface temperatures range from 5 above in western North Dakota to 65 degrees in central Missouri at 3 PM today.
An intense area of frontogenesis helped to produce an area of snow today which impacted parts of northwest Wisconsin back toward Duluth and a small part of far eastern Minnesota with snowfall amounts of 3 to around 9 inches reported under this band today with the highest totals impacting portions of northwest Wisconsin.
Snow will persist over the Northland tonight as another wave ejects northeast out of the Plains which will enhance the lift over our area, this system will move quickly through our area though so the snow should taper off from southwest-northeast during the day Tuesday.
In addition to the snow, there could be some sleet, freezing rain or freezing drizzle tonight mostly over portions of northwest Wisconsin.
Note: Will get a break from this wintry weather Tuesday night through Thursday morning with quite a bit of sunshine expected on Wednesday.
Lows tonight will range from around zero in far northern Minnesota to the teens in eastern Minnesota and northwest Wisconsin. Highs Tuesday will be in the single digits and teens. Portions of the Northland could go subzero Wednesday morning, with highs Wednesday in the upper teens to middle 20s.
Snow could return to the Northland later this week during the Thursday evening-Friday time frame.
