The path drawn at its surveyed width of 75 yards (0.04 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

At least four barns lost portions of their tin roofs and/or walls. Several trees were uprooted or lost limbs. A narrow strip of wheat was blown down. The tornado began on the south side of Hopkinsville and ended several miles southeast of the center of Hopkinsville. Peak winds were estimated near 85 mph.

The wider storm

Clusters of storms, followed by a bowing line of thunderstorms, organized and accelerated east-northeastward during the overnight and wee morning hours. Several tornadoes accompanied mesovortices along the bowing line of storms. In addition, a particularly strong microburst was associated with the line. Finally, the occurrence of multiple thunderstorms resulted in localized flash flooding in the Pennyrile region. A mid-level shortwave trough moved east across the southern Plains. A belt of stronger southwesterly 500 mb winds spread northeast ahead of the trough into southeast Missouri and Arkansas. Instability was sufficient for a round of severe thunderstorms to occur.

Began near Casky (36.8190, -87.4680).
