The northwest suburbs saw plenty of damage as the storms snapped tree limbs.
In Carpentersville, the storm sent a huge tree falling onto a home.
One of the branches went through the roof of Romero Olvera's home. No one was hurt.
"It was almost like a freight train coming though, and I heard a lot of lightning strikes, then I heard a big bang and it was this tree falling," said Olvera. "We're just lucky enough it didn't hit any further into the house."
Barbara McCollum in Marengo says she had planned to cut off a huge limb that had fallen, but now she doesn't have to.
"I was standing out by my window looking out, watching the storm, and, big branch on my mom's tree fell in my driveway," she said.
