This tornado developed west of Miami, to the south of Highway 59 and east of the S 510 Road, where large tree limbs were snapped. The tornado moved east-northeast over open country to the north of Highway 59, and then northeast across Miami where it damaged numerous homes and businesses, uprooted trees, and snapped power poles. The tornado dissipated before reaching Highway 69A on the northeast side of town to the south of the E 70 Road. It was observed by multiple people. Based on the damage, maximum estimated wind in the tornado was 85 to 95 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.
