Locally Severe Storms to Rattle Michigan, Illinois, Wisconsin

Locally severe thunderstorms will affect areas across northern Illinois, Wisconsin, Michigan and central Ontario into Friday night.

While not every location will be hit with a thunderstorm, a few communities can be hit hard with damaging wind gusts, large hail, frequent lightning strikes and flash flooding.

Some cities that can be impacted by downed trees, sporadic power outages and travel delays include Chicago and Rockford, Ill.; Milwaukee, Madison and Green Bay, Wis.; Grand Rapids, Alpena and Flint, Mich.; and Sudbury, Ontario.

Spotty, wind-driven downpours can affect motorists along stretches of I-43, I-75, I-90 and I-94.

The storms will be moving along at a swift pace and could catch some people off guard who may be on the lakes or on the roads.

Labor Day Weekend: Warmth, Storms

Keep an eye out for rapidly changing weather conditions. Seek shelter indoors as storms approach and never drive through flooded roadways.

During early Saturday, the storms can reach other cities including Indianapolis, Detroit, Toledo, Ohio, and London, Ontario.

The storms are occurring on the northeastern edge of a large dome of heat anchored over the central Plains.

Additional storms are likely through Sunday, before a push of cooler and drier air settles southeastward over the region during Labor Day and Tuesday.
