Lake effect/ lake enhanced snow could become a concern this afternoon-tonight into northern IL & southeastern WI, this includes portions of the Milwaukee & Chicago suburbs. Locally impressive snowfall amounts of 5-9” could occur! This would make travel very hazardous with low visibility & slick conditions locally. #weather #snow #chicago #Milwaukee #heavysnow #forecasting #ILwx #WIwx

Cold air is rapidly coming into the eastern US as the upper-level trough arrives. Portions of the Midwest are 40°+ colder than at this time yesterday! This cold air will continue to move east over the next couple of days. #weather #cold #winter #INwx #ILwx #OHwx #USwx #forecast
