CHICAGO — Flight cancelations are reported at Chicago airports as much of Illinois gets snow as part of a storm hitting the Midwest and beyond.

The National Weather Service says a weather system will be rolling through the Chicago area until sunset on Monday. Forecasters say 3 to 6 inches of snow is expected.

A Lake Effect Snow Warning goes into effect at 7 p.m. tonight until 4 p.m. Tuesday.

Snow started Sunday. Snow in the Chicago area and elsewhere is leading to more than 500 cancelations at Chicago’s O’Hare and Midway airports.

The last time Chicago received any significant snowfall was in mid-December, when there was a little more than 5 inches of snow on Dec. 11 and 3.5 inches of snow days later.

Since the first of the year, what rare flurries the city has seen have added up to less than an inch of snow.
