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

Some tree damage with several power lines down. Two farmsteads were struck causing damage to several barns and feed bins.

The wider storm

Strong to severe thunderstorms ignited across portions of central, south-central and east-central Kansas during the afternoon and evening hours on the 20th, along and north of a warm front. The thunderstorms became supercellular as they moved north of the warm front, producing a handful of tornadoes across portions of Barton, McPherson and Marion counties. Severe straight-line winds also slammed the community of McPherson, producing some damage across town.

Began near Durham (38.4905, -97.3578).
