UPDATE: The severe thunderstorm warnings and watches issued Sunday night have since been canceled.

Multiple weather alerts were issued across portions of the Chicago area on Sunday evening, as storms moved toward the region, bringing the possibility of damaging hail and fierce wind gusts.

A severe thunderstorm watch was issued for LaSalle, Grundy, Kankakee, Kendall and Will counties in Illinois, as well as Newton and Jasper counties in Indiana until midnight. Additional severe thunderstorm warnings were issued earlier Sunday evening, but had since been canceled.

According to the Storm Prediction Center, most of northern Illinois is at a “marginal” risk of severe weather on Sunday night, as is most of northwestern Indiana.

New guidance from NWS suggests that a narrow band of thunderstorms could potentially develop in areas to the west and south of Chicago, impacting DeKalb, LaSalle, Kendall, Grundy, Will and Kankakee counties, as well as the southern portion of Cook County.

The storms are expected to trudge slowly across the region, moving to the east at around 30 miles per hour, according to forecast models.

More rain could potentially impact the area on Monday, though it could be scattered in nature. Temperatures will also be cooler, with highs dropping into the 60s.

Those will likely rebound into the 70s by Wednesday, according to extended forecast models.
