A storm and trailing cold front will continue to slowly move through the Gulf Coast and Southeast U.S. through this weekend with widespread rain showers and isolated thunderstorms. A fast-moving clipper storm may bring several inches of snow to the north-central Plains, Midwest, eastern Great Lakes, and Northeast regions this weekend. Read More >

Accumulating snow will spread across northern Illinois late this evening and overnight. A narrow band of locally heavier snow is expected to develop roughly around the I-88 corridor, where snowfall rates may exceed 1 inch per hour for several hours. Closer to the Wisconsin line and especially south of I-80, snowfall rates will quickly diminish. Most of the accumulating snow is expected to taper off by around sunrise.
Here is an approximate timeline of when accumulating snow is expected to begin tonight. Note rain/freezing rain may mix in with snow across portions of Livingston, Ford, Iroquois, Kankakee, and Benton Counties overnight, but temperatures are expected to be near 31-33 degrees, limiting icing impacts.
Our period of wintry weather will continue through next week with several chances for precipitation including rain and snow. While temperatures will start off on the chilly side, they do look to moderate towards the middle of next week.
