The tornado clock, which applies to Kenosha County, will end at 22:00, according to the National Weather Service. This watch was released as a cool front bounces off the Chicago area late Wednesday and overnight, and while storms are raging along that front, it remains unclear if any will strengthen beyond severe limits. Any thunderstorms could potentially cause catastrophic winds, hail and even isolated tornadoes, according to NWS and the NBC 5 Storm team. The front is expected to reach DeKalb County at 10 p.m. hour, and will continue to move northeast as midnight approaches. Temperatures are still expected to be on the toaster on Thursday, but lower temperatures are expected to eventually prevail in the area until Friday, although highs are still likely to remain in the 1980s in most locations. Stay tuned to the NBC 5 app and the NBC 5 Storm team for all the latest details.
