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 is the second segment of a six-segment tornado. (The first, third, and fifth segments occurred in Franklin County in the Tulsa County Warning Area.) The tornado moved out of Franklin County east-northeast of Branch and entered Logan County 2.17 miles west-northwest of Ratcliff. The tornado clipped a small corner of Logan County, snapping and uprooting trees. The tornado then exited Logan County 1.86 miles northwest of Ratcliff and moved back into Franklin County south-southeast of Peter Pender.
