The weather service is expecting snow in parts of Cook, DuPage and Lake counties and has issued a winter weather information Thursday morning.

Officials said 2 to 4 inches of snow was expected to accumulate near the I-290 corridor and 4 to 7 inches near the Wisconsin border by about 6 p.m.

The heaviest snowfall is expected between 8:00 PM Thursday and 2:00 AM Friday. Snowfall rates are expected to peak at about 1 inch per hour Thursday evening, officials said.

Heavy sleet is expected to make shoveling dangerous for some, officials warned.

A persistent storm on the west coast created Atmospheric river bringing moisture to the northern/central Plains and the Great Lakes and Appalachians, officials said. More precipitation is expected on the west coast.

A dangerous weather forecast was issued Thursday morning for parts of north-central and northeast Illinois and northwest Indiana. Increased snowfall is expected in these areas, especially north of I-80. Several inches of “sloppy” and sleet are expected to accumulate, with the heaviest amounts near Wisconsin, officials said.
