Cooler air will settle into Chicago Thursday and Friday in comparison to unseasonably hot weather Tuesday and Wednesday. The weekend outlook will mostly benefit outdoor plans in the area.
The recent heat will diminish across Chicagoland Thursday into Friday in wake of cold front that passed through the city early Wednesday. Despite the cooldown, it will remain mild for the middle of May. Highs will average in the mid- to upper 70s, but it will be cooler along the lakefront.
A disturbance will bring plenty of clouds along with a shower or thunderstorm on Friday to the city. There may be a lingering shower in the area on Saturday, but a mixture of clouds and sun along with dry weather will dominate much of the upcoming weekend.
Vendors and visitors to the Green Festival at the Navy Pier should prepare for a brief shower or two on Saturday; however, mostly dry and warm weather will be around for the balance of the weekend. Participants in the Walk Now for Autism Speaks at Soldier Field on Saturday can expect temperatures in the 60s to start the walk before the afternoon high reaches the upper 70s; a passing shower cannot be ruled out.
