A winter storm is still on track to deliver heavy snow to portions of North Dakota, Minnesota and Wisconsin Saturday evening into Sunday and Sunday night. I suspect that some roads will be impassable on Sunday due to the heavy snow and strong winds.

Forecast models agree that this weekend’s winter storm will hit northern Minnesota the hardest. The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential precipitation pattern from 6 p.m. Saturday through 11 p.m. on Sunday:

NOAA’s High-Resolution Rapid-Refresh (HRRR) model shows a similar precipitation pattern:

Notice the tight spacing of the isobars Sunday and Sunday night, indicating very strong winds.

Snow totals from Saturday evening through Sunday evening are expected to be in the 6 to 10 inch range in much of northwestern Minnesota:

North-central and northeastern Minnesota will probably see many 8  to 12 inch totals from late Saturday night through Sunday and into Monday, with more than a foot of snow close to Lake Superior:

Central Minnesota will tally some 4 to 6 inch amounts overnight into early Sunday.  

Periods of snow are possible Saturday evening and overnight Saturday night in the Twin Cities metro area. The north metro, including Anoka County, could see an inch or two by Sunday morning. Lighter amounts are expected in the south metro. The metro area could also see a few light snow showers and sprinkles on Sunday.
