A new winter weather advisory has been issued for much of the Chicagoland area as another 2-3 inches of snow is expected to fall during the Monday morning commute.

The National Weather Service (NWS) issued the advisory Sunday afternoon.

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

The winter weather advisory will go into effect from 3 a.m. Monday and expire at 12 p.m. on Monday.

Light snow is expected to develop late Sunday evening across northwest Illinois and spread across all of the area by early Monday morning.

Untreated surfaces will become snow-covered and slippery.

The snow will continue through the Monday morning commute, the NWS said.

“Plan on slippery road conditions. The hazardous conditions will impact the morning commute,” the advisory said.
