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

Several sheds experienced roof damage and/or wall collapse. The tornado tracked along a nearly five-mile path between Trenton and Allensville, ending at Highway 102. Peak winds were estimated near 85 mph.

The wider storm

A strong cold front moved through the region, preceded by numerous thunderstorms during the evening hours on December 5th and into the early morning on the 6th. Large hail, a few tornadoes, and an isolated damaging wind event accompanied the strongest storms. There were four tornadoes that touched down in the Tennessee border counties of western Kentucky. A loose clustering of storms and embedded supercells caused most of the severe weather in the evening. Overnight, the severe weather was mostly in the form of a convective line with embedded mesoscale circulations. The severe storm environment was characterized by weak instability but very strong wind shear.

Began near North Zion (36.7400, -87.1700).
