The National Weather Service has issued an excessive heat warning for Friday for much of southern Minnesota, including the Twin Cities, Rochester, Mankato, Albert Lea, Austin, Winona and Red Wing.

"High temperatures in the mid- to upper 90s will combine with high humidity to yield dangerous heat indices on Friday," the Weather Service reported. "Peak heat indices in the 100 to 110 range appear possible."

The warning also includes parts of western Wisconsin, including La Crosse, Hudson and Eau Claire, and portions of northern Iowa. It's in effect from late Friday morning through Friday night.

An excessive heat watch remains in effect for Friday for areas to the north and west of the warning, including St. Cloud, Willmar and Cambridge, Minn.

A heat advisory — for conditions somewhat less warm than the warning area — is in effect for Friday for parts of southwestern Minnesota, including Worthington and Marshall.

There will be a chance of thunderstorms — some possibly strong — across much of the state on Thursday night, Friday and through the weekend.
