7 Inches Of Snow Before -40 Wind Chill Moves In To IL

A week full of wintry weather is ahead of us, starting with some heavy snow on Sunday night into Monday. The National Weather Service has issued a winter weather advisory which is in effect from 9 p.m. Sunday until 6 p.m. Monday for Kane, DuPage, Cook, Kendall, Grundy and Will counties.

The NWS said heavy snow and blowing snow will begin Sunday night and continue into Monday. Total snow accumulations of 3 to 7 inches are possible.

The snow could impact the Monday morning commute, and could make travel very difficult. Generally, the farther north you live, the more snow you'll receive, with most of the Chicago suburbs falling in the 4 to 7 inch or 3 to 5 inch range.

After the snow on Monday, possibly historic cold will move into the area. The high for Tuesday during the day is 3 degrees, according to the NWS. Temps will then drop to -20 on Tuesday night with wind chills of at least -40. Wednesday will be even colder, with highs of -10 degrees during the day with wind chill values of -30. Thursday will be the last day of the cold snap, with a high near 2 degrees.
