The path drawn at its surveyed width of 100 yards (0.06 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

This weak tornado tracked across rural farm country between Wingo and Cuba. Mainly trees and large tree branches were down. There was damage to a few barns and a chicken house. 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 Wingo (36.6200, -88.7200).
