The path drawn at its surveyed width of 100 yards (0.06 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

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 National Weather Service conducted a storm survey across Simpson County. The tornado began just southwest of Lake Spring Road where a couple of trees were snapped or uprooted and a large 24 x 36 barn experienced extensive roof panel damage.

The tornado threw metal sheeting from the barn in various directions with much of it suspended up in the trees. There were a couple twisted trees on both sides of Highway 31W. Maximum winds at this location were 75 mph with a width of 75 yards. The tornado lifted on the northeast side of the highway.
