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

An EF0 tornado with maximum winds 70 to 80 mph briefly touched down around 645 am in northeast Coffee County. Aamage was noted along Swann and Rock Roads. The damage path was around 1 mile long and 50 yds wide.

The wider storm

During the early morning hours on Wednesday, April 27th, twelve tornadoes occurred across Middle Tennessee. Seven of these were EF0 tornadoes and five of these were EF1 tornadoes. Numerous thunderstorm wind damage events, along with several flash flooding events, occurred across the mid state also. This severe weather outbreak was the result of a very unstable airmass across Middle Tennessee ahead of a strong frontal system, with a warm front positioned near the Tennessee/Alabama border. As this frontal system pushed across the area through the remainder of the morning through the early evening hours, several thunderstorm wind and flash flood events also occurred as additional severe thunderstorms developed.

Began near Ragsdale (35.5267, -85.9974).
