What the National Weather Service wrote
The Washington-Slaugherville tornado, the sixth of the outbreak, formed on the east edge of Washington and moved east and northeast crossing Interstate 35, and then crossing the Canadian River into Cleveland County due west of Slaugherville. In McClain County, a few homes suffered roof damage, and numerous trees along the path were damaged.
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 Washington (35.0580, -97.4760).
