What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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

The tornado touched down 5 miles southwest of Middletown, on the west side of Swope School Road, just north of intersection with Highway A. In this location, several trees and tree branches were blown down. The tornado moved to the southeast, crossing Highway A and then as it crossed Trinity Church Road, several large tree limbs were snapped off and blocked the road. The tornado continued to the southeast for almost two more miles with additional minor tree damage before lifting and dissipating near the intersection of Nagel Road and Poppy Road, about 4 miles south southwest of Middletown. Overall the tornado was rated EF0 with a path length of 2.54 miles and a max path width of 40 yards. No deaths or injuries were reported.
