A winter weather advisory will go into effect this evening in anticipation of 2-4 inches of snow expected to fall in Lake and McHenry counties Monday morning.
The National Weather Service (NWS) said the winter weather advisory will go into effect at midnight tonight and expire at 12 p.m. Monday.
The advisory covers Lake, McHenry, Boone, Winnebago, Ogle, Lee, DeKalb and Kane counties.
Snow is expected to spread across the area late Sunday evening into Monday morning.
The NWS said wet snowfall rates up to one inch per hour are possible between midnight and 3 a.m.
After a lull in precipitation intensity and a transition to some freezing drizzle, accumulating snow is expected again pre-dawn through mid-morning.
Total snow accumulations of 2-4 inches are possible, the NWS said in the advisory.
The NWS said drivers should plan on slippery and hazardous road conditions that will impact the Monday morning commute.
The snow is expected just two days after the northern Illinois area saw temperatures reach 70 degrees on Saturday.
