What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

A tornado with estimated peak winds of 110 mph touched down just east of Ashley Road about halfway between Sherrill Road and Whitewillow Road. The tornado moved east northeast producing sporadic tree damage until it crossed County Line Road and moved into Will County, just south of Mound Road.
