Big Weather Change Coming To Chicago Area This Weekend
CHICAGO, ILLINOIS — Residents across the Chicago area will notice a major weather change beginning this weekend, as summer-like highs in the 80s give way to cooler-than-average conditions in the 70s, bringing what some may call an early taste of fall.

According to the National Weather Service, Thursday and Friday will remain comfortable, with highs around 79–81°F under mostly sunny skies. While the overall pattern will be dry, forecasters say a few sprinkles or even an isolated storm could develop late Friday into Saturday, especially south and east of Interstate 55.
Saturday’s forecast calls for highs near 81°F, with partly sunny skies and breezy west winds gusting up to 20 mph.
Sunday Brings Noticeable Drop
