This tornado stripped siding off of two walls at the Portillo's at Ramblewood Dr. and Barrington Rd. while also causing some tree damage and blowing around light debris along its track. Tree damage also continued east of Barrington Rd. into Hanover Park, though witness accounts and the broadening nature of a predominantly southwest to northeast oriented damage field suggest that this damage was caused by strong southwesterly straight-line winds of up to 75 mph that descended to ground level right as the tornado was lifting.

After the first tornado in the O'Hare area lifted, a second EF-0 tornado touched down within the confines of O'Hare Airport just south of the I-90 overpass over Touhy Ave. The tornado initially caused minor roofing and fascia damage to buildings and warehouses on the far north side of the airport. Minor tree damage also occurred in this area, and a parked car was impaled by debris that was thrown by the tornado. The tornado then tracked east across I-90 and into Rosemont, where it blew over a light pole and ticket booths in the Allstate Arena parking lot and caused damage to trees and signs along Mannheim Rd. Video footage taken in Rosemont showed the tornado (which did not necessarily have a fully condensed cloud-to-ground funnel at all times) track into a residential area on the southeast side of Des Plaines, where it produced a concentrated area of tree damage, caused minor roofing and fascia damage to some houses, and caused a few power poles to lean. The tornado may have lost contact with the ground as it crossed the Des Plaines River, but it eventually touched down again in Park Ridge, where it produced tree damage in a neighborhood east of Maine South High School before lifting for good.
