Friday was deemed an AccuWeather Alert Day due to the potential severity of storms.
The storms Friday night brought down trees, hitting cars on the North Side and toppling onto houses in the suburbs.
A homeowner in northwest suburban Park Ridge found part of a tree on his home.
"Right after the rain started coming down real hard, I was sitting in the living room. I heard a loud crash and saw these branches hitting the windows and half of a tree now sitting on my house," said resident Jeff Walters.
Gusty winds ripped down power lines in Sleepy Hollow, while lightning struck a house in Wilmette. Bricks crumbled to the ground, but there are no reports of any injuries.
"I was in the basement on a phone call and our kids were playing video games and all of a sudden, we heard a big loud boom" said homeowner Ben Currie.
Wilmette Fire Department Battalion Chief Ryan Menzies said the lighting "blew out the backside of the chimney."
"It also looks like it struck the tree a little bit in the back," Menzies said.
