Here’s my updated preliminary snowfall accumulation map for Wednesday night and Thursday – Additional adjustments in snowfall totals are possible during the next 24 hours.
Note: Most of the snow in northern Minnesota should fall Wednesday night/Thursday morning while the snow in northwest Wisconsin, Twin Ports, North Shore and eastern Minnesota occurs on Thursday.

…Latest on the system for Wednesday night and Thursday…
-Computer models continue to show significant changes from run to run (every 6 hours) Makes this forecast a lower than average confidence forecast.
-One thing the computer models do agree on is that there is going to be two main areas of accumulating snowfall with potential for 3 to possibly 6 inches of snow underneath these bands.
-The first area of snow is expected to impact portions of west central and northern Minnesota Wednesday night into Thursday morning.
-The second area of snow could impact portions of south central Minnesota into west central and northern Wisconsin — It’s this second area of snow that has the least confidence due to uncertainty on where it sets up, and this has been very evident per the last few model runs which keep shifting this band west and east.
