Weather officials expect snow in portions of Cook, DuPage and Lake counties and issued a winter weather advisory Thursday morning.
Officials said about 6 p.m., snow is expected to accumulate near the I-290 corridor from 2 to 4 inches, and 4 to 7 inches near the Wisconsin border.
The snowfall is expected to be the heaviest around 8 p.m. Thursday until 2 a.m. Friday. Snow rates were expected to peak near 1 inch per hour early Thursday evening, officials said.
The heavy wet snow is expected to make shoveling hazardous for some, officials warned.
A persistent storm on the West Coast created an Atmospheric River bringing moisture into the northern/central plains and the Great Lakes and Appalachians, officials said. More rain is expected on the West Coast.
A hazardous weather outlook was issued Thursday morning for portions of north central and northeast Illinois, and northwest Indiana. An elevated snow risk is expected in those areas, especially north of I-80. Officials said several inches of “sloppy” and wet snow is expected to accumulate with the highest totals near Wisconsin.
Current temperatures at O’Hare Airport were overcast at 37 degrees and at Midway Airport it was the same.
