Multiple Rounds Of Storms Possible This Week For Chicago Area

The Chicago area could see multiple rounds of storms through Wednesday. A hazardous weather outlook has been issued for northeast and north central Illinois and northwest Indiana as storms are in the forecast Sunday evening, according to the National Weather Service. But the bulk of those storms, which could produce gusty winds and small hail, should be east of Interstate 57.

But rain and storms will continue as the work week gets underway. Late on Monday afternoon and evening, widespread measurable rainfall is expected. The Chicago area will remain in a "busy pattern with multiple chances of storms" possible through Wednesday, according to the National Weather Service.

Meanwhile, many in the Chicago area will be powering up their air conditioners, if they haven't already, in the week ahead. Hot and humid temps returned in recent days and weather officials are predicting that very warm weather pattern could continue through late September.
