What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 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 tornado from a QLCS (quasi-linear convective system) storm developed in northeast Norman about a half mile northwest of 24th Avenue NE and Rock Creek Road, and moved generally northeast into southwest Oklahoma City dissipating northwest of SE 164th Street and Anderson Road. The damage was most intense from a half mile south to about a half mile east of the intersection of 36th Avenue NE and Franklin Road where the tornado produced roof damage to two barns, and damaged the soffit to a carport at a home. Otherwise, the tornado produced damage primarily to trees along the path.

The wider storm

A dryline and strong upper trough combined to produce numerous thunderstorms during the evening and overnight period of the 26th into the 27th. Storms produced isolated extreme wind gusts early in the event, with sporadic wind damage and a tornado then reported in central Oklahoma.

Began near Norman (35.2580, -97.4130).
