CHICAGO — Winter weather bearing down on Chicago has caused nearly 500 flights to be canceled and snarled traffic on the Dan Ryan Expressway after a semitrailer overturned near 83rd Street Saturday morning, causing southbound lanes to close for much of the day.
More than 370 flights have been canceled at O'Hare International Airport, and more than 105 at Midway Airport, city officials said.
A winter storm warning for Cook County remained in effect until 6 p.m., and meteorologists predict as much as 8 more inches of snow will fall on the area by this evening. Meteorologists predict a high of 29 Saturday, with the temperature dipping to 6 degrees overnight.
The city's full fleet of 287 snow plows is on the streets, tackling first main routes and Lake Shore Drive before moving to side streets, said Molly Poppe, Department of Streets and Sanitation spokeswoman.
While February is off to a snowy start, the National Weather Service said January's snowfall totals were the third-highest on record since 1884 with 33.7 inches.
