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 EF-0 tornado touched down along Rock Springs Road south of Chenault Lane, heavily damaging a barn and blowing down numerous trees. The tornado then moved east across Lauderdale Lane and Homer Scott Road, continuing to blow down trees. Turning more southeast and entering Trousdale County, the tornado damaged several homes and blew down dozens of trees along Highway 231, Templow Road, Bass Road, Walnut Grove Road, and Gore Lane. Total path length of 5.05 miles.

The wider storm

A QLCS (Quasi-linear Convective System) moved across Middle Tennessee during the early morning hours of May 4, 2021. This line of thunderstorms spawned a total of 14 EF-0 tornadoes throughout Middle Tennessee, at least 4 of which were captured on video by local residents. In addition to the tornadoes, significant straight-line wind damage also affected many other areas of Middle Tennessee, and was just as damaging as the tornadoes in many cases. Thankfully, no injuries or deaths were reported.

Special thanks goes to Middle Tennessee emergency management, tSpotter coordinators, and the public for their assistance and helpful information with these difficult and lengthy storm surveys.

Began near Castalian Spgs (36.4226, -86.3137).
