EF1 tornado in Nowata County, Oklahoma

This tornado developed east of Lenapah where large tree limbs were snapped on the N 4150 Road, and moved north-northeast uprooting trees and snapping large tree limbs. It was observed by multiple people. Based on the damage, maximum estimated wind in the tornado was 90 to 100 mph.

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.
