NOAA recorded where this tornado touched down but not where it lifted, so it appears as a point. 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

Brief tornado reported by KWTV and a Spotter Network storm chaser.

The wider storm

A dryline was located from western Kansas through the Texas Panhandle during the afternoon, with a moist, unstable airmass in place over Oklahoma as a shortwave trough approached. Numerous thunderstorms developed during the mid- to late-afternoon hours over much of western and central Oklahoma, with some displaying supercell characteristics at times. Widespread large hail was reported, some significant, along with isolated damaging winds.

Began near Minco (35.2691, -97.8899).
