The latest round of severe winter weather in Chicago was causing problems at the city’s airports Sunday morning, before temperatures are expected to nosedive overnight into Monday.
More than 160 flights had been proactively cancelled at O’Hare International Airport as of 7:45 a.m. on Sunday due to snowy conditions, according to the city’s Department of Aviation. At least 70 flights have been cancelled at Midway Airport.
Before snowfall stops around noon today, between 2 and 5 inches will have fallen across most Chicago area counties, according to the National Weather Service.
The Chicago Department of Streets and Sanitation deployed 200 snow plows and salt spreaders this morning to clean up main routes in the city, according to department spokeswoman Molly Poppe.
Wind gusts of up to 40 mph this evening could make for “near-blizzard conditions” at times, the weather service said.
After Sunday, temperatures are not expected to reach positive values until Wednesday. The forecasted high is 0 degrees for both Monday and Tuesday.
A wind chill advisory goes into effect at 3 a.m. Monday and lasts until Wednesday morning, with wind chill values plummetting as low as 45 degrees below zero.
On Friday, Metra was already warning commuters of likely delays starting Monday due to the frigid temperatures, according to a service alert posted on the transit agency’s website.
“We will make every reasonable effort to provide a timely and comfortable commute. However, trains are likely to be delayed,” the alert said.
