"Most of the severe weather was actually reported up around Wisconsin. As the storms moved to the south and east, it looks like it's starting to diminish a little bit, although we still have some pretty good storms," said ABC7 meteorologist Jerry Taft said around 6 p.m.
The storm was expected to strike Monday evening, but the cold and wind will stick around -- for a few days.
The major drop in temperature is expected Monday evening, with temperatures falling into the 60s. That cold will stick around Tuesday, when it's possible Chicago will see a record low-- around 40-degrees -- overnight Tuesday into Wednesday.
