According to ABC7 meteorologist Tracy Butler, 70 mph winds were reported at O'Hare at around 1:30 a.m.
The wind is to blame for a crumbled wall at an airport hangar. Bricks were tossed into the parking lot. There were no injuries.
Grazyna Demonte lives in the 2800-block of Craig Drive, which was hit hard by sheets of rain and strong wind.
"It started between 12:30 and lasted until 2:30," said Demonte.
The storm also knocked out power in the Des Plaines, Park Ridge and Rosemont areas, where you could see darkened traffic and railroad crossing signs.
"The storm, I mean the wind was just whipping everywhere," said Des Plaines resident Joe Catalano. "It sounded like hail, but I didn't see any hail."
