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 formed southwest of the community of McKey, and moved southeast initially, before turning to the northeast and dissipating northwest of Sallisaw. The tornado uprooted trees, and snapped large tree limbs along its path. Based on this damage, maximum estimated wind in the tornado was 90 to 95 mph.

The wider storm

Strong to severe thunderstorms developed during the evening of the 5th over southeast Colorado, southwest Kansas, and the western Oklahoma Panhandle. The storms moved southeast through the early morning hours of the 6th, evolving into a well-organized squall line by the time they moved into eastern Oklahoma. The line of strong to severe thunderstorms produced several tornadoes and damaging wind across eastern Oklahoma.

Began near Mc Key (35.4831, -94.8753).
