If you have outdoor plans Friday afternoon into Friday evening, stay weather-aware.
Northwestern Minnesota was already seeing areas of rain with a few embedded thunderstorms at midday. Thunderstorm coverage is expected to expand into more of Minnesota and also into parts of western Wisconsin as we go through the afternoon and evening hours. Some severe weather will be possible, especially late Friday afternoon into Friday evening.
The Storm Prediction Center of the National Weather Service shows a slight risk (shaded yellow, level 2 out of 5) of severe weather Friday afternoon into Friday night in portions of Minnesota and Wisconsin:
Slight risk means that scattered severe thunderstorms are possible. Isolated severe thunderstorms are possible in the darker-green shaded areas.
