A muggy Saturday with scattered thunderstorms

It'll feel very summery this Saturday in central and southern Minnesota, with dew point temperatures in the upper 50s to lower 60s and high temps in the upper 80s to around 90 degrees.

Scattered thunderstorms are expected Saturday afternoon and evening over eastern Minnesota and into Wisconsin, and some of those thunderstorms could become severe.

The Storm Prediction Center of the National Weather Service shows a slight risk of severe weather Saturday and Saturday night for northeastern and southeastern Minnesota, as well as western Wisconsin.

The remainder of eastern Minnesota, including the Twin Cities metro area, is in the marginal risk category:
