CHICAGO — Several counties across the Chicago area are under Winter Storm Warnings and Advisories through Tuesday, as heavy snow has torn through the Chicago area.

A Winter Storm Warning and Winter Weather Advisory will be in effect until 9 a.m. Tuesday.

The heaviest “system” snow on the order of 4 to 8-inches will be mainly east of I-57 and I-294, tapering off to the west over our area with amounts ranging from 1 to 3-inches well to the west of the Fox River Valley. The lake-effect snow showers will greatly impact counties along the Lake Michigan shoreline where 3 to 6-inches additional snow could fall (see pictorial below prepared by the Chicago National Weather Service).

Heavy snowfall moved in for Monday’s evening commute and is expected to continue into Tuesday.

Parts of Cook County is estimated to get between 8 to 12 inches of snow by Tuesday.

Dangerous wind chills in the -15 to -25-degree range will continue Monday morning, with a Wind Chill Advisory in effect area-wide. The very cold Arctic air mass centered over south-central Canada and the northern plains will continue to dominate here with single-digit daytime highs and zero to sub-zero nighttime lows. If outside bundle-up and protect bare skin from frostbite that could develop in a matter of minutes.

Snow fall totals as of Monday at 9 p.m.

Low visibility and messy conditions are reported across area roadways. Take it slow if you do have to travel and allow extra time. Currently, the worst of it on the roads is in Northwest Indiana.

The snow storm is also causing flight cancellations and delays at both O’Hare and Midway airports. Check the status of your flight here.

Warming centers in Chicago will remain open as temperatures in the city and across the region linger well below freezing.
