CHICAGO, ILLINOIS — A significant and potentially high-impact spring storm is expected to move across the Midwest Sunday through Monday, bringing a sharp divide in weather hazards across Illinois, Wisconsin, Michigan, Indiana, and surrounding states.
Forecast guidance shows a strengthening low-pressure system tracking through the region, creating a classic spring setup: heavy snow and possible blizzard conditions to the north of the storm track, with strong to severe thunderstorms in the warm sector to the south.
Heavy Snow and Blizzard Potential North of Chicago
Colder air wrapping around the northwest side of the low will support a swath of heavy snowfall across portions of:
- Eastern Iowa
- Northern Illinois
- Much of Wisconsin
- The Upper Peninsula of Michigan
- Northern Lower Michigan
Communities including Duluth, Minneapolis, Green Bay, Hancock, Iron Mountain, and Sault Ste. Marie are positioned within the heavier snow axis.
Forecast signals show a high probability of 12 inches or more across parts of Wisconsin and the Upper Peninsula of Michigan. As the system strengthens, increasing wind speeds could combine with heavy snow to produce blizzard conditions, particularly across northern Wisconsin and the U.P., where open terrain may allow blowing and drifting snow to significantly reduce visibility…
