A blast of wintry weather rakes Minnesota the rest of this week. First, snow. Next, wind. Then another shot of subzero cold.

The forecast models are grabbing hold of a stronger system as it rolls through Minnesota. Expect snow and wind to be vigorous at times through Wednesday. Wind gusts to 50 mph and blowing snow will cause whiteout conditions across parts of western and southern Minnesota at times Wednesday.

Check out NOAA’s NAM 3 km resolution afternoon (18Z) forecast model run. You can see the coverage and intensity of snowfall increase overnight. By Wednesday morning, bands of heavy snow and high winds will rake most of Minnesota. Travel conditions will deteriorate rapidly overnight and be dangerous by Wednesday morning.
