Accumulating snow is expected across the Chicago area Sunday and Sunday night with heaviest amounts of two to four inches along and west of Interstate-39 as well as counties adjacent to the Illinois-Wisconsin state line, where a Winter Weather Advisory is in effect.
One to three inches of snow is forecast for the remainder of the Chicago area. Snow will be steady and accumulate some on less-traveled roads, while main highways will be more apt to be in better shape. If planning travel, be prepared to take a little longer and watch for slick spots.
A Winter Weather Advisory continues until 6 a.m. Monday in Lake County, where an additional one to three inches of snow accumulations are possible tonight. There’s also an advisory in effect until 12a.m. in Kankakee, Iroquois, Newton and Jasper counties, with very light accumulations there, and in McHenry, DeKalb and La Salle counties with one to two inch accumulations is expected this evening.
Plan on slick roads, parking lots and sidewalks, as well all lower visibility in these areas. Travel could be difficult.
Later tonight into Monday morning northeast winds off Lake Michigan will enhance snow accumulation in southeast Wisconsin and primarily Lake and McHenry Counties – possibly Cook County, Illinois.
