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

A weak tornado touched down along Valley Springs Drive south of Ridge Road causing trees to fall in a convergent pattern to the east northeast. The tornado moved northeast causing trees to be uprooted, twisted and snapped. Several homes in the track sustained minor roof and siding damage. The greatest damage was located along Ridge Road between Dittmer Ridge Road and Sylvan Place. The tornado lifted near Cedar Tree Drive with only minor tree damage noted. Overall, the tornado was rated EF0 with a path length of 2.63 miles and max path width of 80 yards.
