CHICAGO — The area is dealing with a sharp drop in temperatures Saturday night after a storm hit Chicago at exactly the wrong time to start the weekend.
After Friday night's snow and sleet, west wind gusts at 45 mph will cause any wet snow and slush to rapidly freeze.
Wind chills will be between -10 and -20 Saturday night for the area and over -20 degrees in most of the area by Sunday morning.
Snow began falling across the area around 4 p.m. Friday, just as the evening commute was getting underway. A Winter Weather Advisory expired at 6 a.m. Saturday.
Snow fell fast for several hours, accumulating in several areas.
Hundreds of flights were canceled at both O'Hare and Midway airports. The weather caused O'Hare to put a Traffic Management Program in effect for about two hours. Passengers are urged to check with their airlines.
The Kennedy is a MESS!! We’re on our way back to the WGN-TV studios from McHenry and it’s taking 2.5+ hours. It’s normally an hour drive 🤦🏻♀️ pic.twitter.com/vlm8WRy4HL
