When Snow Will Stop, Timing For Heaviest Snowfall In Illinois

ILLINOIS — After a snowy weekend, more snow is expected Monday through Tuesday evening, bringing 8 to 13 inches to Cook County and 5 to 9 inches in parts of Will, DuPage and Kendall counties — on top of the snow the area has gotten since the end of January.

A winter storm warning remains in effect for Cook County through noon Tuesday, with 8 to 13 inches of snow possible — and even more in some areas — along with dangerous travel, low visibility and wind chills near minus 20 degrees. During the heaviest snow, "travel will be very difficult to impossible," with the worst conditions late Monday afternoon through Tuesday morning, the National Weather Service said.

For DuPage, Kendall, northern and southern Will counties, a winter storm warning is in effect until 9 a.m. Tuesday, with a wind chill advisory in effect through noon Monday.

If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency. Use caution while traveling outside. Wear appropriate clothing, a hat and gloves.

And while a warmup is coming, wind chills of minus 10 to minus 20 degrees are expected through Tuesday. Temperatures will rise into the mid-20s by Thursday, according to the National Weather Service. By next week, we could see temperatures in the mid-30s.

So when we can expect the heaviest snow? It depends on where you live. According to the National Weather Service, here's what the timing looks like:

• Northeast Illinois near the lake (including Chicago): Heavy snow, possibly 1 to 2 inches per hour, starting around noon Monday and lasting into Tuesday morning, tapering off by late morning. Lake effect snow will continue through Tuesday night.
• South and east of I-55/I-57: Steady snow through Monday morning, with heavier snow by afternoon. Snow should taper off overnight and stop by mid-morning Tuesday.
• North and west of I-55: Possible dry periods Monday morning through afternoon, with snow starting back up after 6 p.m. and becoming steady until around midnight before tapering off again. Snow should stop by 7 a.m. Tuesday.
