Weekend forecast: Cooler and much less humid

Rain chance Sunday evening northwest

Before I get to the weekend forecast, I’ll mention the thunderstorm chances this evening and overnight. Some strong to severe thunderstorms could spread across parts of central and southern Minnesota and portions of Wisconsin this Thursday evening and overnight Thursday night. Our thunderstorm chance in the Twin Cities metro area is mainly after 11 p.m. and into Friday morning.

The NWS Storm Prediction Center shows an enhanced risk (beige-shaded) of severe weather this Thursday evening and overnight Thursday night for southwestern Minnesota and parts of west-central Minnesota:

There’s a slight risk (shaded yellow) of severe thunderstorms elsewhere in southern and central Minnesota and parts of western Wisconsin. Slight risk indicates that scattered severe thunderstorms are possible, while enhanced risk means that numerous severe thunderstorms are possible:

Some areas could also receive heavy rainfall amounts overnight and early Friday.

Stay sky aware this evening, and have a way to receive severe weather warnings this evening and overnight.
