CHICAGO - A clash of air masses on Wednesday will result in the threat of severe storms from Milwaukee and Chicago westward to Denver and the eastern Rockies. The Storm Prediction Center has placed large parts of Illinois, Wisconsin, and Colorado under a "slight" risk of severe storms - a Level 2 out of 5 on its severe storm scale.

The Chicago area has felt less of an impact from the Trump administration’s National Weather Service cuts than offices in the Quad Cities and downstate Lincoln.

A Chicago flash flood warning went out Tuesday night as the city experienced some of its heaviest rain since 2023. More than 4 inches fell in less than 90 minutes on the West Side.

CHICAGO (WLS) -- There is a chance of severe weather Wednesday afternoon. Wednesday will be very hot and humid, with highs in the low 90s. Between about 3 and 8 p.m., strong to severe storms are possible, ABC7 Chicago meteorologist Larry Mowry said.

In parts of Chicago, flash flood alerts rang Tuesday, warning of dangerous conditions as cars were stranded and submerged on highways and water rescues were conducted, but how much rain actually fell across the region and how fast did it all happen?

Wednesday will be another hot and humid day with highs in the lower 90s. Showers and storms are expected to move in during the afternoon and evening, some of which may become severe. The greatest risk with any strong to severe storms on Wednesday will be damaging wind gusts and heavy rain.

Chicago weather remains unsettled heading into the weekend, with the possibility of more severe storms Friday that could produce tornadoes and flooding. One to five inches of rain fell across the Chicago area Thursday night into Friday, with the heaviest rain falling west of the city. There was significant flooding in Rockford, Illinois.

Early Friday morning, torrential rain fell across Cook County. Multiple crashes were reported on Chicago roads and highways and thousands were left without power across the Chicago area.
