What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 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 130 mph touched down along Bungalow Road, east of Gun Club Road producing sporadic tree damage. The tornado moved east northeast along the Illinois River and just before it crossed into Will County, the tornado expanded in size and was likely at its maximum path width of 325 yards as it was crossing into Will County between Lauren Drive and Old Kerry Grove Road. Several trees and utility poles were blown down in this area.
