After highs in the 70s Thursday afternoon, Chicago is in for a cool down throughout the weekend.
Friday afternoon will bring a high of only 50 degrees with scattered clouds, before dropping down to the high 30s at night.
Saturday may creep down into the high 40s with even more clouds. The nighttime will bring temperatures to the high 30s.
Both days will be breezy, so those spending time outdoors should consider a light jacket. Precipitation is unlikely.
Thunderstorms will move into the Chicago area later this week, and the threat for storms will remain into the weekend.
Minneapolis will have sunshine and slightly below-average temperatures continue on Wednesday before pop-up storms move into the region on Thursday and Friday.
