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

A brief tornado developed over open country. No damage resulted from the tornado.

These storms moved east across the region producing damaging wind, large hail and flash flooding. Another round of severe thunderstorms moved into eastern Oklahoma from the west during the late afternoon and evening hours producing damaging wind and flash flooding.
