Blizzard warnings are in effect from much of western, central, and southern Minnesota. The western Twin Cities is included in the blizzard warning zone. That’s a fairly rare event.
Winter storm warnings include the greater Twin Cities area northward through northeast Minnesota.
Rain changed to snow just before noon in the southwest Twin Cities.
Storm winds up
The storm is still on track, cranking up high winds and heavy snow across Minnesota. NOAA’s NAM 3 km resolution model shows the progression of heavy snow bands from Mankato through the Twin Cities to Duluth and the North Shore.

The heaviest snow bands will fall between 2 p.m. and 7 p.m. Wednesday. Snowfall rates could reach 1 to 2 inches per hour.
Snowfall totals
Most forecast models still crank out the heaviest snowfall zone from Mankato through the Twin Cities to the North Shore. A consensus suggests snowfall totals between 6 and 12 inches in and around this zone. There could be some locally higher totals.

Here’s NOAA’s NAM model from the morning (12Z) run Wednesday.
High winds
Wind gusts could reach 60 mph in open areas of western Minnesota. I expect gusts over 50 mph in the Twin Cities late this afternoon and evening. temperatures will plunge into the teens and single digits by this evening. That may produce “flash-freeze” conditions as precipitation freezes rapidly on roads and walkways.

The combination of high winds and heavy snow will make travel difficult to impossible this afternoon and evening in much of Minnesota.
