NWS said survey crews confirmed an EF-1 tornado in Lansing and EF-1 tornado damage across Country Club Hills, Hazel Crest, Harvey, and Homewood.
The Lansing tornado appeared to lift just east of the Illinois-Indiana state line in Munster, NWS said. That tornado produced peak winds near 110 mph.
NWS also confirmed an EF-0 tornado in Glen Ellyn and an EF-0 tornado in Orland Park.
The Glen Ellyn tornado produced peak winds near 80 mph.

NWS investigated video footage showing a possible tornado touchdown near Watseka, Illinois in Iroquois County. NWS was unable to confirm contact with the ground, so it is being categorized as a funnel cloud.
Surveyors remained in the field on Tuesday afternoon. They are looking at damage in several areas, including Glenwood and Markham, and it may take some time to complete those surveys.
Meanwhile, hundreds of thousands of people lost power during the storms.

A ComEd spokesperson said crews were working extended hours and expected to restore power to about 80% of affected customers by the end of the night.
Across the south suburbs, homes and buildings sustained significant damage. At a University Park apartment building, part of the roof was torn away by the storm.
The damage left residents displaced in communities, including Homewood, Lansing, and Hazel Crest.
Shelter opens as storms knock out power for south suburban residents
A community center in Steger has been transformed into a Red Cross shelter for residents across the south suburbs affected by damaging storms that left many displaced or without electricity for hours.
As communities worked to recover, local organizations, volunteers and businesses stepped in to provide assistance to those impacted by Monday's storms.
Crews with E&R Towing delivered pallets of water and food to residents, including seniors living at a retirement facility in Homewood that lost power during the storm.
"We've had drivers come in, put in double hours to fill the trucks up," said Ben Charlton of E&R Towing.
Community activist Early Walker said volunteers quickly organized relief efforts as outages spread throughout the area.
"We've got tons of power outages throughout the community, so we just decided to go into action," Walker said.
Residents at the Homewood senior facility expressed concerns about enduring high temperatures and losing food without electricity.
"What are we going to do with all this heat and no lights? Our food is spoiling," said resident Dollnetta Jordan, 82.
Tunisia Gilliard, whose mother lives at the facility, said the building should have emergency backup power.
"This is a senior building. It's a lot of medically fragile residents. So, they should definitely have generators," Gilliard said.
Public works crews across the region continued cleanup efforts, clearing debris and reopening roads.
"We're just trying to get at it, you know, cleaning everything, opening the roads for emergency vehicles, and the coolest bit about it all, as we were driving around, opening things up, just the neighborly love. Everyone was out helping each other," said Joshua Burman, Homewood's public works director.

Roofs ripped from buildings, man rescued from home after tornado hits Lansing
Lansing sustained significant damage, particularly near Wildwood and 192nd Place.
Bill Simon said he and his son made it to the basement just in time before the storm intensified.
"It was like, I swear it was like 'The Wizard of Oz.' It was like spinning and it was... I never saw anything like it. It was like a cyclone," Simon said.
"The whole house started just to vibrate, like a giant was shaking the house. And I heard all the glass blow out," he added.
Deniz Sidkey said he and his wife were home when the storm struck. Sidkey, who said he has stage 4 cancer, credited a stranger with helping them escape after they became trapped inside.
"It was unbelievable, 'cause some guy I don't even know helped me get out of there. You know, he climbed into the house. The door opened finally, 'cause I, we couldn't open the door, me and the wife. Mm. So crazy," Sidkey said.
Rob Griffin said the force of the storm knocked him down and ripped open his home.
"I felt pushed. I bumped into the wall, and I'm thinking like, 'Who pushed me?' But I looked back, and all I seen was dark. And it, I fell on the ground, closed my eyes, and everything started happening that quick," Griffin said.
Griffin and his fiancée said they are grateful no one was injured, but residents continue to cope with the emotional toll of the destruction.
"I mean, to just see your home, you, somewhere that you called your sanctuary, you don't have it no more. And I'm always in my bedroom, and the whole roof just... I could've been in that bed, and that's all I, in my head I'm saying like, 'I could've been in the bed.' The whole roof collapsed. So, it, it's, it's hard," Lansing resident Lawonna King said.
As residents begin the recovery process, many are left confronting not only extensive property damage but also the trauma of narrowly escaping harm during the storm.
Several people suffered injuries in Lansing, but officials say no one was seriously hurt.
"I grew up in this neighborhood," Lansing Mayor Brian Hardy said. "I've been in Lansing almost 60 years. I've never seen any kind of devastation like this. It breaks my heart. But again, I'm going to have to just go back to thank the Lord that no one was seriously hurt."
Parts of Hazel Crest left unrecognizable
Robert Redmond said he was at work when the storm hit his Hazel Crest home. His mother and two young children were inside and took shelter in the basement.
Standing in front of the damaged home, Redmond pointed to the destruction and said, "That's my bed, literally where it fell in."
He said his daughter called him in a panic during the storm.
"My daughter was really frantic talking about how it's a tornado and everything is gone. The house is gone. The roof is gone. My son was really scared," Redmond said.
Parts of Hazel Crest were difficult to recognize after the storm. Most of the townhomes in one damaged complex are uninhabitable.
Village of Hazel Crest spokeswoman Nakita Cloud urged residents not to remain in unsafe buildings.
"Do not try to stay in a unit that is not safe. The American Red Cross has placement in Steger. I know it's a little bit of a hike but they have shelter there," Cloud said.
An apartment complex was also heavily damaged.
Chopper7 over storm damage in Hazel Crest
Daylight truly reveals the devastation. A lot of the village is almost unrecognizable as block after block is littered with debris from the severe weather.
Most of the townhomes in one complex have been left uninhabitable.
"The roofs are gone. All the brick molding is off from the front of the back. The windows are blown out, of course has water damage inside," said a man who said he's the property manager for a few of the properties.
A steady stream of the curious came to see the damage for themselves. Laura Taylor came over to see how she could help even though she said a tree fell on her house Monday night.
"The damage was in the back," Taylor said. "I was still able to stay in the house overnight, but I'm gonna get out to a hotel because, doesn't know when the lights are gonna be back on."
Meanwhile, some area officials are urging people to stay in their homes if they can until fallen trees and downed power lines are secured.
It's little comfort to Redmond, who just needs some help.
"A lot of things are coming out of pocket right now, and you're trying to rebuild and an emergency situation. So we can find help, will accept it," Redmond said. "If we can't, we'll do what everybody does and continue to move forward."
Hazel Crest postponed the Hazelnut Festival, which was set to take place this weekend, due to storm cleanup. Village officials are is asking for it to be a village-wide day of clean up after the storms.
Toppled trees impact traffic amid cleanup in Glen Ellyn
Tornado damage blocks streets in Glen Ellyn as neighbors rally to help
And more than 24 hours after a tornado struck Glen Ellyn, several streets remained impassable as crews and residents continued cleanup efforts in hard-hit neighborhoods.
On Forest Avenue, many of the area's century-old oak and maple trees were toppled by the storm. A number of trees fell onto homes, and some houses were covered with tarps as residents worked to address roof damage. One street remained blocked by a tree that had snapped in half and fallen onto power lines.
The neighborhood was filled with the sounds of generators, chainsaws and contractors working as recovery efforts continued. Power outages also persisted in the area.
Residents said they sheltered in their basements as the tornado moved through and emerged to find widespread damage throughout the neighborhood.
"I've been here for a long time, and I'm very attached to the neighborhood, so it really does make me very sad but also very grateful that nobody was hurt," said Kathy Cornell, a Glen Ellyn resident.
Doug Bober described the destruction left behind by the storm.
"The amount of damage that came through just at that one particular time in such a short moment was crazy. I've never seen so many trees on top of houses," Bober said.
Despite the damage, residents said the storm brought neighbors together.
"I've met more neighbors in the past night or day than I ever thought I would," Michelle Bober said. "The community has just really come together to support each other. We got a text at 6am. What's your coffee order? What can we do to help you guys out? So it's really been cool to see the community come together and rally."
Tree removal remained ongoing, and village officials said that as of the morning, about 1,800 customers in Glen Ellyn were without power. Officials said they hoped 80% of those customers would have electricity restored by tomorrow afternoon.
As recovery efforts continued, neighbors shared generators, refrigerator space and extension cords, helping one another navigate the aftermath of the storm.
Storm damage cleanup expected to take days in Orland Park
Storms topple 60-foot trees, knock out power in Orland Park
Cleanup is expected to take several days, and possibly weeks, in parts of Orland Park after powerful storms that spawned an EF-0 tornado moved through the area Monday afternoon, damaging homes, vehicles and trees and leaving some residents without power.
One homeowner said trees more than 60 feet tall fell onto his home, shaking the foundation during the storm.
Video recorded by a neighbor on Huntington Court, just north of 151st Street, showed pouring rain and strong winds as conditions intensified.
Homeowner Zach Schaults said his family sought shelter after seeing storm damage begin to unfold.
"As soon as I saw a branch knock the door off of my shed, we all ran into the bathroom and then we just started hearing thumps and bumps all over the roof, and a big crash," Schaults said.
Schaults said they remained sheltered for about 20 minutes as the storm passed.
"I told my sister and brother, you know, put on your shoes and your boots and get in the bathroom because we're in the middle of a tornado. I couldn't confirm that, but that's my instinct," he said.
After the storm, Schaults found a large tree branch had fallen onto his house. Across the neighborhood, residents reported damage that included trees falling onto cars, homes and yards.
"When things cleared up around, I don't know, three or 4 o'clock, we went outside and it was disaster," said Orland Park resident Ron Spielman.
Spielman, who has lived in the neighborhood for 55 years, said his son and a friend were using chainsaws to remove damaged trees. A generator was powering his home because electricity remained out in parts of the neighborhood.
Village of Orland Park crews were working to clear roads and remove hazardous hanging branches.
Storm damage was also reported elsewhere in the south suburbs. In Tinley Park, the new i80 Sports Dome was left flattened. In Frankfort, the roof over the fuel pumps at the Speedway at Laraway and Center roads was torn off, and crews were removing sections of sheet metal.
Tim Falardeau, owner of Vic Roofing, said he experienced intense conditions during the storm while checking on friends in Orland Park.
"The sirens just kept going off left and right, and then all of a sudden we had a strong howling wind, like a growling in a way," Falardeau said.
Falardeau said one home he inspected appeared to have sustained about $45,000 in damage.
"People always say you hear a tornado - it sounds like a freight train coming through. I understand what they mean now, because that's definitely what it sounded like over here," he said.
Meanwhile, village officials said curbside chipper service will begin Wednesday and continue through Aug. 5 for residents clearing brush and storm debris from their properties.
