What EF3 means. On the Enhanced Fujita scale, EF3 is severe damage: whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, consistent with estimated gusts of 136–165 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

The twelfth tornado of the outbreak developed about 2 miles south-southeast of Pink. This tornado was very slow, moving only 0.6 mile in 5 minutes near the intersection of Okay Road and Willow View Road. A metal truss electric transmission tower collapsed in the tornado and is the source of the EF3 rating. The tornado also damaged at least two homes and numerous trees.

The wider storm

Broad troughing was present aloft across the Western US during the afternoon/evening of the 19th. An area of surface low-pressure slowly deepened and moved towards north-central Kansas, with dryline extending from central Kansas through western-north Texas by the late afternoon hours. A well-timed lead upper wave, combined with broken insolation, led to the development of a few supercell thunderstorms across central Oklahoma. Multiple instances of large to very large (>2 inches) hail, along with 18 tornadoes, occurred across central Oklahoma.

Began near Pink (35.2290, -97.1110).
