CHICAGO — The National Weather Service has issued a Winter Storm Warning for McHenry County. It will remain in effect until noon Wednesday.

Winter Weather Advisories and Winter Storm Warnings remain for several Chicago-area counties including DuPage, Cook, Lee, Lake, Kankakee, Kane, Will, Grundy, Kendall, LaSalle, DeKalb

A wintry mix of snow, ice and freezing rain is blanketing the Chicago area and will carry through to Wednesday morning.

Some schools are closing early Tuesday due to the weather. Check for the latest.

The wintry mix will create ice and treacherous conditions on outdoor surfaces, including untreated roads. Precipitation will change to rain overnight in the south suburbs.  A mix will continue in the city, and snow dominates north and west suburbs.

Precipitation will gradually change over to snow in all areas toward Wednesday morning. Total expected snowfall is 3 inches to 6 inches in the far North and Northwest. One inch to 3 inches are expected in the city — especially on the North Side tapering to a dusting or less south.
