Winter storm warnings in Wisconsin; accumulating snow in SE Minnesota

Major storm to dump heavy snow Tuesday night across much of Wisconsin

Talk about a close call.

A major wintry storm will dump heavy snow across much of Wisconsin and produce accumulations in southeastern Minnesota Tuesday night.

The system is a panhandle hook-type storm. It winds up in the Texas and Oklahoma Panhandle region and spins across southern Lake Michigan Wednesday.

The National Oceanic and Atmospheric Administration’s Global Forecast System model shows the snow shield intensifying across Wisconsin and clipping southeastern Minnesota Tuesday night into Wednesday:

Snowfall totals will likely reach 12 inches with this system across much of central and eastern Wisconsin. The heaviest snowfall will likely fall in northeastern Wisconsin around Green Bay.

A cooler spell early next week gives way to what could be the warmest temperature so far this year for Minnesota around the weekend of April 13-14. NOAA’s Global Forecast System model is cranking out highs in the mid to upper 70s that weekend.
