The path drawn at its surveyed width of 900 yards (0.51 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 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 tornado formed approximately 2.3 miles east of Rocky Hill near Goldenrod Lane and tracked northeast for approximately 1.1 miles before crossing into western Barren County. The tornado continued approximately 9 miles into Barren County before crossing into southern Hart County. The tornado traveled approximately 7 more miles into Hart County before dissipating near Red Buck Estes Road at approximately 0154 CST. In Hart County, the tornado continued along US 31W through downtown Horse Cave. Here the damage was rated EF1 with small roof damage, large limbs being snapped, and walls blown out of some older tobacco warehouses. Once reaching Dawson Knob the tornado weakened and likely converged with the supercell moving into Hardyville. Due to the knob terrain in this area, there are spots of weaker damage found, however on the down-sloping side, the tornado strengthened rapidly. This pattern was found twice in this damage path.

The wider storm

Strong southern winds brought warm temperatures and plenty of moisture into an environment of strong wind shear ahead of an advancing cold front. This resulted in unusually warm temperatures for a December day and the ingredients to produce a historic tornado outbreak and flash flooding. This included multiple long track tornadoes. Central Kentucky saw 18 tornadoes that injured 96 and killed 18. An additional death occurred in a flash flood.

Began near Horse Cave (37.1520, -85.9410).
