Tornado in Mayes County, Oklahoma

Multiple people observed a tornado over Lake Hudson. NWS Tulsa surveyed the area on the east side of the lake and found no damage, so the tornado was believed to have developed and dissipated over the lake.

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.
