The path drawn at its surveyed width of 50 yards (0.03 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

A third tornado from a QLCS (quasi-linear convective system) storm system that affected the Oklahoma City area developed over Forest Park near Northeast 36th Street and Bryant Avenue, and moved northeast into northeast Oklahoma City dissipating northwest of Northeast 63rd Street and Midwest Boulevard. The damage observed was generally broken tree branches and limbs.

The wider storm

A warm front lifted north during the afternoon and evening of the 12th, with a couple supercells developing along it across southwest OK. Large hail, strong winds, and numerous tornadoes were reported with these storms as they moved northeastward. Later, a line of severe storms moved into far western OK along a cold front, with strong winds and hail reported with these storms.

Began near Forest Park (35.5080, -97.4595).
