Damaging storms swept through the Midwest, knocking out power to hundreds of thousands of customers and causing more than a thousand flight delays or cancellations at Chicago airports.

The National Weather Service issued tornado warnings Wednesday across Illinois, Kansas, northern Missouri and southern Iowa, while severe thunderstorm watches were in place for parts of the Great Lakes.

Storms moved into the Chicago area on Wednesday afternoon, downing trees and damaging some buildings.

The two major Chicago airports, Chicago O’Hare International Airport and Chicago Midway International Airport, temporarily put all flights on hold in the evening due to thunderstorms. A similar ground stop was issued at John F. Kennedy International Airport in New York due to thunderstorms.

By Wednesday evening, more than 1,000 flights going into and out of Chicago had been delayed or canceled, according to FlightAware, a flight tracking website.

Strong winds blew part of the roof off an apartment building in the Chicago area, forcing residents to leave, according to NBC 5 Chicago. Elsewhere, barns collapsed in Wisconsin, buildings were crushed in rural northern Missouri and some large trees and power lines were downed in other areas across the Midwest, photos and video online showed.

More than 264,000 customers had no electricity in Illinois, the majority in Cook County, and nearly 140,000 were without power in Michigan, according to poweroutage.com. There were also outages in Kansas, Wisconsin, Iowa, Indiana and Ohio.

Commonwealth Edison Company, which provides electric service across northern Illinois, said the storms had downed poles and wires.

“We know this is challenging and will restore service as safely and quickly as conditions allow,” the company said in a post on X.
