The National Weather Service says snow amounting to one to two inches is possible starting early Sunday morning in the Chicagoland area.

The National Weather Service (NWS) issued a hazardous weather outlook early Saturday morning for northeast and north-central Illinois.

The outlook includes Lake, McHenry, Cook, Winnebago, Boone, Ogle, Lee, DeKalb, Kane, DuPage, LaSalle, Kendall, Grundy, Kankakee, Livingston, Iroquois, Ford and Will counties.

The outlook said snow would develop across the area after midnight Saturday.

Snow-covered roads will result in slippery travel conditions on Sunday morning, the NWS said. A higher risk will be on elevated or untreated surfaces.

The snow will persist “well into Sunday” with the highest rates from 4 a.m. to 10 a.m. Light snow could persist into the evening.

The NWS said the total snowfall could amount to around one to two inches.
