The path drawn at its surveyed width of 40 yards (0.02 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

An EF0 tornado touched down along Highway 464 near Almo and travelled to the northeast before lifting. Several trees and limbs were downed. One large oak tree was uprooted. Minor damage was done to siding on a home. There was one eyewitness to the tornado. Peak winds were estimated near 80 mph.

The wider storm

Scattered thunderstorms increased along an axis from central Arkansas into southeast Missouri and southern Illinois, then moved east across western Kentucky. These storms moved through a region of marginal instability, but deep-layer vertical wind shear was sufficient for isolated severe storms. The complex of storms contained very heavy rainfall that resulted in localized flash flooding.
