Some light snow and mixed precip possible at times late tonight-Wednesday evening; chilly lake wind the next few days

Chances for some snow, rain, patchy sleet and freezing rain are in the forecast across the Northland beginning later tonight and lasting through Wednesday evening. No major accumulations of snow or ice are expected with little impact to travel, but it’s possible we could see a narrow band or two of heavier precipitation develop between late tonight and Wednesday afternoon, and if this occurs, then there is a chance for a quick 1-3″ of snow where-ever these bands set up, but model guidance is all over the place as to where these bands of heavier precipitation will set up, if they develop at all.

Simulated radar valid from 7 PM this evening to 7 PM Wednesday.

There’s a large area of warm temperatures (70+ degrees) extending from Alberta and Saskatchewan, SE through much of the Northern and Central Plains today, but this warmth won’t make it into the Northland as it gets pushed S-SE thanks in part to a developing NE flow off Lake Superior.
