The morning rain and cloud cover limited instability in the atmosphere, allowing this afternoon's severe weather threat to be lowered, ABC7 meteorologist Larry Mowry said.
Up to an inch of rain is expected as the system of rain and embedded thunderstorms moves through, Mowry said.
The rainfall was welcome along the Wisconsin border, where parts of Lake and McHenry counties are experiencing moderate drought conditions.
Following the passage of the cold front, temperatures will crash into the 30s overnight. A Wind Advisory has been issued for Thursday, with gusts up to 50 mph forecast.
