Storm Summary for November 20-21, 2024

Winter Weather Expected Over Most of Lower Michigan Friday!

The National Weather Service offices across the western Great Lakes have all issued Winter Weather Advisories for this snowfall event that is expected to continue, even over Iowa into northern Illinois and Wisconsin into early Friday afternoon and over Lower Michigan into the early evening of Friday.

The following slides will show you the details of this event that is expected to bring up to 10″ of snow in about 12 hours to some locations in western Great Lakes. It will likely be the heaviest snowfall over most of the area since mid February.

Snow Expected over Wisconsin and Michigan late Thursday into Friday.

A narrow band of snowfall greater than 6″ in 12 hours is expected about 100 miles north of the track of the surface low. That would be near or just north of I-96 in Michigan. Snowfall rates in the heaviest snow area will be high enough to accumulate during the daytime, even in late March.
