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

This tornado moved out of Cleveland County crossing Pottawatomie Road just southeast of 89th Street/Memorial Road. The tornado moved east-northeast producing tree damage, roof damage to a home and flipping an RV as it approached Interstate 40. The tornado continued to produce tree and power pole damage moving east and northeast before dissipating after crossing State Highway 270 just north of Garretts Lake Road.

The wider storm

A powerful storm system, with highly anomalous magnitudes of wind shear and moisture for late February, impacted the forecast area on the evening of the 26th. A broken line of severe thunderstorms developed across the eastern Texas Panhandle/far western Oklahoma and quickly swept through much of the forecast area. Widespread wind damage, including gusts near 90 mph, along with a record number of tornadoes (13) for February occurred. Several reports of large hail were also received. Behind the line of thunderstorms, a tight pressure gradient and strong westerly low-level jet allowed widespread 50-60 mph winds gusts to continue through the late evening hours.

Began near Dale (35.3750, -97.1420).
