"A rare storm packing 100 mph winds and with power similar to an inland hurricane swept across the Midwest on Monday, blowing over trees, flipping vehicles, causing widespread property damage and leaving hundreds of thousands without power as it moved through Chicago and into Indiana and Michigan.
The storm, known as a derecho, lasted several hours as it tore from eastern Nebraska across Iowa and parts of Wisconsin and Illinois, had the wind speed of a major hurricane, and likely caused more widespread damage than a normal tornado, said Patrick Marsh, science support chief at the National Weather Service's Storm Prediction Center in Norman, Oklahoma.
In northern Illinois, the National Weather Service reported a wind gust of 92 mph near Dixon, about 100 miles west of Chicago, and the storm left downed trees and power lines that blocked roadways in Chicago and its suburbs. After leaving Chicago, the most potent part of the storm system moved over north central Indiana by late afternoon."
