EF1 tornado in Adair County, Oklahoma

This is the second segment of a two segment tornado. The tornado moved east-northeast into Adair County south of the E 830 Road, uprooting trees as it crossed the 4610 Road. The tornado dissipated after crossing the 834 Road, where trees were uprooted. Based on this damage, maximum estimated wind in this segment of the tornado was 95 to 105 mph.

Severe thunderstorms developed over central Oklahoma along and ahead of a dry line during the afternoon of the 19th, as an upper level disturbance approached the Southern Plains. These thunderstorms moved northeast off the dry line and across portions of eastern Oklahoma during the mid afternoon and evening hours. The atmosphere east of the dry line across eastern Oklahoma became very unstable during the afternoon and evening, and this instability combined with strong deep-layer and low-level wind shear, resulted in the development of a few supercell thunderstorms and a severe squall line. Multiple tornadoes, large hail slightly larger than golf ball size, and damaging wind gusts occurred with these thunderstorms across eastern Oklahoma. Locally heavy rainfall also produced some localized flash flooding.
