Chicago Forecast

Heat Advisory Remains in Effect for Northern Illinois, Northwest Indiana

A view from the 360 Chicago observation deck

It’s a hot and humid day in the Chicago area, with heat indices already exceeding 100 degrees in many locations.

Due to that oppressive heat, the National Weather Service has issued a heat advisory for the Chicagoland area that will remain in effect until 10 p.m.

The heat also sparked a thunderstorm that rapidly developed and spawned a severe thunderstorm warning for parts of Ogle and DeKalb counties early Saturday afternoon. The warning was canceled after the storm's intensity faded, however.

High temperatures are rising into the mid-90s across the region, with the humidity boosting heat indices well into above 100 degrees in some locations, according to current forecast models.

Things are expected to mostly remain dry for the rest of the day, but that could change on Sunday, as a chance of showers and thunderstorms will creep into the forecast. Some of those thunderstorms could be strong-to-severe thanks to the intense heat and humidity, according to forecasts.

Temperatures will cool very slightly on Sunday, dropping into the low-90s in most locations around the area.

More cooling will take place on Monday, as temperatures are expected to dip back into the 80s for most locations. A chance of rain will return to the mix on Tuesday and Wednesday, with temperatures sticking around the mid-to-upper 80s mark for most of the work week.
