Residents in the Chicago area took shelter and kept a watchful eye on ominous skies for hours Wednesday as tornadoes whipped through the area.
The National Weather Service confirmed numerous tornadoes moved through the area about 7 p.m, prompting a tornado warning for Cook County and tornado watch for surrounding counties.
Warnings were lifted by 7:45 p.m., though residents were advised to stay indoors and monitor weather reports for much of the evening.
A tornado touched down near O’Hare International Airport around 7 p.m., the weather service confirmed. The tornado was “touching the ground intermittently” and moving east, according to a tweet from the weather service. Cook County was under a tornado warning after a tornado was confirmed east of South Elgin, the agency said.

Sirens warning of tornadoes were heard in various parts of the city Wednesday evening, and weather alerts lit up phone screens.
Flights were grounded at Midway and O’Hare airports. Normal fight operations resumed at Midway about 7:45 p.m. with departure delays of at least 15 minutes. Flights at O’Hare also resumed about 8 p.m., with ongoing delays.
A tornado watch was in place for DeKalb, DuPage, Grundy, Kane, Kankakee, La Salle, McHenry and Will counties until 10 p.m. A tornado watch means a tornado is possible; it is less severe than a tornado warning, which indicates that a tornado has been spotted or is expected by the weather service.
The main areas at risk of tornadoes were between Interstate 80 north toward the Wisconsin/Illinois state line, according to the weather service.
The hail and winds expected in the area could be severe enough to damage cars and buildings and down fences and trees.
Three years ago, a tornado with winds peaking at 110 mph ripped through the Rogers Park neighborhood on the North Side, leaving behind damaged buildings, downed trees and power outages. No major injuries were reported despite the heavy damage.
On a scale of 0-5, the severe weather threat was categorized as a 3 by the weather service early Wednesday evening.
The city’s Emergency Management Department will be prepared with flood mitigation equipment and coordinate with the departments of Streets and Sanitation, Transportation and Water Management, according to a release from Mayor Brandon Johnson’s office.
City officials request that residents refrain from using extra water for showers, laundry or household chores to ease pressure on the city’s wastewater system. Residents can report a backup of water in their homes or businesses by calling 311 or going to 311.chicago.gov to report water in basements, standing water in streets and viaduct flooding.
Jake Petr, a meteorologist with the weather service, said rainfall at O’Hare Airport totaled .7 inches as of 4:30 p.m. At Midway Airport, 1.1.7 inches was recorded.
One of the highest totals for the day in the area was in Romeoville, at 2.63 inches, Petr said.
