At least three tornadoes battered communities outside Chicago on Thursday, leveling homes and ripping down trees and power poles, while storms grounded flights for some and knocked out power for hundreds of thousands in the Midwest and Northeast.
As a large column of air descended on Merrillville, Indiana, a town about 33 miles (53 kilometers) southeast of Chicago, the city’s police warned residents to take cover. By the evening, downed trees and power lines blocked the streets, homes were torn up and part of a high school's roof was ripped off.
Meanwhile, emergency crews were in the nearby manufacturing and farm city of Streator, Illinois, as the community reeled from tornado damage. A reunification center for displaced residents was set up in its city hall and the Red Cross opened a shelter.
Streator Mayor Tara Bedei said there were no reported deaths. “We are incredibly grateful for the safety of our residents and the quick action of emergency personnel,” she said in a statement.
Strong storms delayed or halted flights at airports in some cities, including Chicago, Philadelphia and New York on Thursday. Parts of the Northeast and mid-Atlantic also strained under high heat and humidity.
The tornadoes came after severe storms swept through the Midwest Wednesday, knocking out power, damaging buildings and canceling flights.
In Des Moines, Iowa, a 54-year-old man died at a homeless encampment in a park after being hit by a tree that “broke apart and fell during strong storms,” police said in a statement. The man was found critically injured Thursday morning and died at the scene, authorities said. There were no immediate reports of other deaths or injuries from the storms.
Tornado warnings were also in place in Chicago and in parts of Indiana and Michigan Thursday, according to the National Weather Service. In Chicago, a series finale between the White Sox and the Atlanta Braves was postponed due to rain.
Jennifer Hall was in her garage in Elkhart, Indiana, as the winds and rain picked up Thursday evening. Suddenly, she said, she heard a loud crash and discovered a tree limb had gone through the roof of her rental home. She used buckets to catch the rain coming in from the hole.
“I’m just nervous because it’s just been one thing after another,” said Hall, explaining she just had surgery and her husband is out of town.
Shane Tipton stepped out of his truck in Unionville, Missouri, Wednesday afternoon to find a twister bearing down, said his daughter, Kylie Rouse. He rushed to get his 87-year-old dad out of his mobile home.
They made it back to the truck, drove just far enough away and watched as the tornado obliterated the home. Shattered cabinets, furniture and appliances littered the ground. Clothes hung in trees. They believe they lost one of their hunting dogs, who has been missing since it struck.
“Everything's destroyed,” Rouse told The Associated Press in a phone interview Thursday. “It was scattered clear for miles. If my grandpa would have been in there, there's no way that he would be alive.”
Residents of Springfield, Illinois, believe a tornado touched down in their area late Wednesday. Two buildings at the Animal Protective League shelter in Springfield were heavily damaged, but none of the nearly 150 cats and 28 dogs housed there were injured, said Deana Corbin, the group's executive director.
“It pretty much wiped out our shelter facility, took the roofs off both of our buildings,” Corbin said. “It’s a miracle. We were so blessed to not have any injuries of either people or animals.”
The community pitched in to take in all the cats and dogs temporarily, including a local animal control center, veterinarians and residents, she said.
Damage also was reported at Abraham Lincoln Capital Airport in Springfield.
Weather service meteorologist Frank Pereira said the system that produced the storms, including high winds and hail, was moving eastward Thursday, fueled by cool air from Canada clashing with warm, humid air from the South.
Potentially dangerous heat and high humidity arrived Thursday and was expected to continue Friday for a swath of the East Coast from the mid-Atlantic to the Northeast, where daily high record temperatures could be broken in numerous places, the weather service said. Temperatures in the mid-90s Fahrenheit (mid-30s Celsius) were expected, but with the humidity it could feel like 100 degrees Fahrenheit (38 degrees Celsius) or more, the service said.
Philadelphia declared a heat health emergency for Thursday and Friday, activating cooling centers, home visits by field teams, outreach to people experiencing homelessness and other services. New York City officials were also urging residents to take precautions, including drinking plenty of water and finding a cool place to stay if they do not have air conditioning.
At various points Wednesday and Thursday, ground stops were issued at Chicago's O’Hare International and Midway International airports, and at John F. Kennedy International Airport in New York.
The Pittsburgh International Airport experienced a temporary power outage after a storm produced an “extraordinary” power surge, the airport said.
More than 1,000 flights going into and out of Chicago had been delayed or canceled, according to FlightAware, a flight tracking website.
Commonwealth Edison Company, which provides electric service across northern Illinois, said the storms had downed poles and wires. On X, it wrote that it expected “80% restoration” by late Saturday.
This story was first published June 11. It was updated on June 12 to correct that police said a man in Des Moines hit by a fallen tree was found Thursday, not Wednesday.
