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 developed in Bethel Acres near Bethel Road south of Clear Pond Road, and moved north-northwest dissipating northwest of the intersection of Bethel Road and Lake Road. At least one home and two mobile homes were damaged, including one mobile home that was partially pushed over. This was the sixteenth tornado of the outbreak.

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 Dale (35.3140, -97.0170).
