EF1 tornado in Sequoyah County, Oklahoma

This is the second segment of a two segment tornado. The tornado moved into Sequoyah County west of Gore, and continued to move east-northeast across the north side of Gore. It uprooted trees, snapped large tree limbs, and damaged outbuildings until it dissipated north of the E 1000 Road and east of the S 4469 Road. It produced a tornadic debris signature from the KSRX WSR-88D. Based on this damage, maximum estimated wind in this segment of the tornado was 90 to 100 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.
