The path drawn at its surveyed width of 50 yards (0.03 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

A brief touchdown occurred. The roof of a long metal farm building was lifted across a farm house. Two vehicles parked in a building were heavily damaged. Large tree limbs were down. Peak winds were estimated near 75 mph.

The wider storm

Thunderstorms gradually intensified along and ahead of a cold front from Arkansas into western Kentucky. The storms occurred in a moist and strongly sheared environment, resulting in a combination of line segments and supercells which evolved into a quasi-linear convective system. There were isolated tornadoes, along with a couple small swaths of damaging winds.

Began near Heath (37.0889, -88.8091).
