A winter weather advisory has been issued for much of the Chicagoland area, including Lake and McHenry counties, as 2-5 inches of snow is expected to fall this evening into Sunday.

The National Weather Service (NWS) issued the advisory around 9:30 a.m. Saturday.

The advisory covers Lake, Kane, McHenry, DuPage, Kankakee, Cook, Will, Newton, Jasper, Winnebago, Boone, Ogle, Lee, DeKalb, LaSalle, Kendall and Grundy counties.

The winter weather advisory will go into effect from 9 p.m. Saturday and expire Sunday morning.

A period of accumulating snow is expected to develop late Saturday and continue through daybreak Sunday, the NWS said.

Most areas are expected to see at least an inch of snow accumulation.

Total snow accumulations could range from 2-5 inches, the NWS said in the advisory.

The areas that will receive higher snowfall are likely to be along and between the Interstate 90 and Interstate 80 corridors.

Untreated surfaces will become snow-covered and slippery as this snow arrives, the NWS warned. “Plan on slippery road conditions and sharply reduced visibilities with the heaviest snow.”
