On June 2, 2009, the Quad Cities National Weather Service dispatched a post storm damage assessment survey team to investigate storm damage that occurred north of Freeport, IL near Orangeville. There were several areas along the path of storm damage. A cluster of storm damage in the center of the path was consistent with a brief, weak tornado.
1. Farm equipment blown over in the field, laying to the south. Caused by downburst winds.
