Chicago, Illinois – Scattered thunderstorms threaten evening plans in Chicago Tuesday, with more rounds of heavy rain possible through Saturday, as storm chances stay elevated across northern Illinois. Highs will climb into the mid-80s, keeping humidity levels uncomfortable for much of the region.
According to the National Weather Service Chicago, the first round of storms is most likely from late Tuesday afternoon into the evening, with a 30-50% chance of downpours and lightning. A second window opens on Wednesday, especially near Lake Michigan, where cooler air may temper temperatures but not rain chances. Thursday brings a brief break, though skies will stay partly cloudy and highs will hold in the low to mid-80s.
Travelers should be alert for rapidly changing weather, especially during the Friday evening commute, when the risk of storms climbs again—reaching 40% in the city and higher in western suburbs. Gusty winds and isolated street flooding are possible. Drivers should slow down during heavy rain and keep headlights on. Outdoor events could be interrupted, so keep alternate plans in mind and charge devices in case of power outages.
Storm chances continue into Saturday before conditions start to clear. More updates and alerts are possible if storm severity increases.
