Tornado in Washington County, Oklahoma

This is the first segment of a two-segment tornado. In Washington County, the tornado produced no known damage as it occurred over open country that was inaccessible by road. It was observed by multiple people. The tornado crossed into Rogers County north of the E 350 Road.

Strong to severe thunderstorms developed across eastern Oklahoma during the early afternoon hours of the 30th, to the east of a stationary frontal boundary that was located across north-central Oklahoma into northwest Texas. Moderately strong instability combined with strong wind shear resulted in the development of supercell thunderstorms, which produced multiple tornadoes, including two strong tornadoes, large hail up to half dollar size, and damaging winds. Locally heavy rainfall also occurred across portions of northeastern Oklahoma, which resulted in flash flooding.
