-Lake County (IN) The first round of snow is expected to come through the Chicagoland area through the weekend followed by more snow Monday. Light snow is expected Sunday and could leave up to 3 inches of precipitation, especially along the Wisconsin line, before Monday's main event. The heaviest snow is expected late Monday afternoon through the evening, ABC7 Chicago Meteorologist Greg Dutra said Sunday. Dutra said the worst commute will be Monday evening but heavy snow could linger into the early Tuesday commute as well. He also suggests shoveling a couple times, as the snow will be wet and heavy.
