Wildfire Smoke, Hot Weather To Start Week In Illinois Before Big Change Is Coming

ILLINOIS — The week will start warm, and once again will have hazy skies due to smoke from Canadian wildfires, according to the National Weather Service.

After Tuesday, the weather will change as a cold front moves across the area.

"A cold front will bring showers and some storms across the area Tuesday night, with cooler conditions and periods of rain expected on Wednesday," the weather service said.

Monday will have a high of 86, and the smoke from wildfires will produce hazy skies through Monday night. Tuesday will be windy, with a high of 88.

Storms are possible Tuesday night, and again on Wednesday. A few storms could be strong with locally heavy rain Tuesday night into Wednesday, the weather service said.

Wednesday will be the coolest day of the week, with temps in the 60s north of Interstate 80, and in the 70s south of I-80, according to the weather service.

The chance of rain begins Wednesday night, and chances will continue through both Thursday and Friday. Thursday will have a high of 77, and Friday a high of 78, according to the weather service.
