Thunderstorm chances

There will be plenty of rain-free hours at any given location in Minnesota and western Wisconsin this weekend. Many areas will also see some thunderstorms at times, with severe weather possible.

Scattered thunderstorms could move into northwestern Minnesota Saturday afternoon, then spread to the east and southeast Saturday evening and overnight Saturday night.

The National Weather Service Storm Prediction Center shows a slight risk of severe weather (shaded yellow) in far northwestern Minnesota Saturday and Saturday night:

Slight risk means that scattered severe thunderstorms are possible.

The dark-green shaded area in the remainder of northwestern Minnesota plus west-central Minnesota is in a marginal risk of severe weather Saturday afternoon through Saturday night, which means that an isolated severe thunderstorm is possible. The severe weather outlook will be updated later Friday and also Saturday.

An advancing cool front and upper-level disturbance will combine to ignite more numerous thunderstorms over Minnesota and parts of western Wisconsin Sunday afternoon and evening.

The severe weather outlook for Sunday shows a slight risk (shaded yellow) of severe weather spread over much of Minnesota:
