Snow caused low visibility and covered the roadways in Lake County Wednesday afternoon, with numerous crashes on Interstate 94, including one that shut down the interstate near Wadsworth.

The National Weather Service (NWS) issued a winter storm advisory for Lake, McHenry, Boone, Winnebago, DuPage, Cook, Will, Kane, DeKalb, Ogle, Lee, LaSalle, Kendall, Grundy and Livingston counties.

The weather service warned residents about mixed precipitation, including snow, expected in the northern Illinois area on Wednesday into Thursday.

The advisory said total snow accumulations of three to six inches, with the highest being in far northern Illinois, was anticipated.

Forecasts charts from the NWS initially showed on Tuesday an 81% chance of six inches or more of snow in Waukegan and a 73% chance of six inches or more of snow in Chicago but those estimates were scaled back.
