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

NWS Storm Survey Teams found an area of straight line winds of 70 to 75 mph, beginning at the Hunting Creek subdivision off of Cave Mill Road. Along Cave Mill Road fences were blown down, minor shingle damage to homes occurred, and many pine and cedar trees were snapped and topped.

At the intersection of Curtis and Cave Mill Rd, there was a change in the damage pattern. The damage became more concentrated with gutters, shingles, roof, and soffit damage. Trees were snapped and uprooted facing to the north, northeast, and east southeasterly direction. Clear evidence was found of a weak tornado that formed with winds estimated between 80 and 85 mph. The tornado was slightly elevated off the ground and was very intermittent.

The tornado lifted just before the Marriott TownePlace Suites on Cave Mill Rd, and then there was sporadic straight-wind damage all the way to Ashton Parc Apartments off of Shive Lane. Thornton Furniture had the most damage from the straight-line winds with roofing and facade damage.

The wider storm

During New Year's Eve into New Year's Day, active weather was observed across Kentucky as several waves of low pressure moved along a frontal boundary that was stalled across the region. This resulted in multiple rounds of widespread precipitation, and rainfall amounts of 2 to 4 inches with locally higher amounts observed across the area. As the boundary lifted north as a warm front New Year's Day, strong to severe storms were able to develop within the warm sector ahead of an approaching cold front, with multiple tornadoes and scattered straight-line wind damage being observed.

Began near Greenwood (36.9430, -86.4450).
