Winter Weather Advisory in effect: 1-5 inches of snow on the way

CHICAGO -- A Winter Weather Advisory is now in effect for a large portion of Chicagoland until midnight Friday.

Illinois counties include Cook, DeKalb, DuPage, Grundy, Iroquois, Kane, Kankakee, Kendall, LaSalle, Lee, Ogle and Will.

Indiana counties include Jasper, Lake, La Porte, Newton and Porter.

The afternoon commute could be a problem.

1 to 5 inches of snow will cause increasingly difficult and hazardous driving conditions to develop across much of the Chicago area, the snow beginning Friday afternoon and continuing until later Friday evening. Highways will be snow-covered , slippery and traffic will be slowed considerably during the afternoon/evening commute.

A wide band of accumulating snow is forecast to spread into the Chicago area from the west – reaching westernmost portions of the area late morning, eventually covering the remainder of the area into northwest Indiana by mid-afternoon. Two to five-inches of snow are expected with heaviest snowfall generally in the vicinity and south of Interstate-80. Snowfall should decrease as you go north with only 1 to 2-inches expected in counties adjacent to the Illinois-Wisconsin border.
