A bit cooler Sunday; lots of 70s this coming week

Saturday night thunderstorm chances in southern Minnesota

The Saturday afternoon high temp was 79 degrees at Minneapolis-St. Paul International Airport. That was a bit above our average Sept. 11 Twin Cities high of 75 degrees. We’ll be a bit cooler on Sunday.

Saturday night rain and thunder chances

Scattered showers will spread across parts of northern and central Minnesota Saturday evening and overnight Saturday night.

Some scattered showers and thunderstorms will spread across portions of southern Minnesota and into parts of Wisconsin late Saturday evening and overnight Saturday night. A shower or thunderstorm could also clip the southern part of the Twin Cities metro area overnight Saturday night.
