Thursday severe weather risk; cool and mostly dry this weekend

Weekend lows in the 30s for northern Minnesota

A low-pressure system and an approaching warm front will spread areas of thunderstorms across much of Minnesota and western Wisconsin Thursday afternoon and evening.

A few severe thunderstorms will be possible. Some spots could see an isolated severe thunderstorm in the early afternoon. More numerous severe thunderstorms are possible later Thursday afternoon and Thursday evening.

The National Weather Service Storm Prediction Center shows an enhanced risk of severe weather Thursday afternoon and evening in southeastern Minnesota and parts of southwestern Wisconsin, with a slight risk of severe weather elsewhere in southern Minnesota and through the Twin Cities metro area and into west-central Wisconsin:
