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 began along Big Woods Rd where several trees were snapped and proceeded east northeastward resulting in additional tree damage and damaged multiple chicken houses along Jupiter Rd before it reached the city of Mendenhall. Several trees and utility lines were downed throughout the city, some fell on homes. Power poles were snapped. A shed was pushed over along Dixie Ave, the roofs were peeled from some buildings in the downtown area, and one roof was lofted into power lines along W Jackson Ave. The brick facade of a downtown church was blown down. East of the city, the tornado continued across US 49, Eugie Palmer Rd, Poplar Springs Rd, and Ponder Mason Rd, before it lifted around Everett Church Rd. Along the path there were multiple distinct focused damage areas, suggesting this might have been a series of smaller tornadoes, which resulted in damage over a somewhat wider area. The maximum wind speed was 105 mph.

The wider storm

On December 28th, an outbreak of severe weather took place. Initially, a few isolated supercells storms developed and produced some tornadoes. As this occurred, a line of storms also developed and eventually pushed eastward across our region. Widespread damaging winds occurred with the line along with numerous tornadoes. This particular convective system was extremely efficient at producing tornadoes. This resulted in a record number of tornadoes for the month of December. The total across our forecast area was 43. The previous December record was 24 back in 2022.

Began near Merit (31.9382, -89.9617).
