The path drawn at its surveyed width of 125 yards (0.07 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

This tornado produced some minor tree damage, shingle damage to a home and some tin scattered about. The tornado continued to move north-northeast and crossed the state line into Clark County Kansas. Monetary damages were estimated.

The wider storm

Thunderstorms developed during the afternoon ahead of a dry line that was located near the Texas panhandle and Oklahoma border. The thunderstorms quickly became supercells as they moved toward southwest Kansas. Very large hail was the initial threat, although a significant tornado threat became apparent as they neared the Kansas border. Three tornadoes were reported with the thunderstorms, with two of them doing significant damage. The tornadic thunderstorms moved northeast by nightfall, with other less severe thunderstorms developing farther south. Monetary damages were estimated.

Began near Buffalo (36.9503, -99.6923).
