EF1 tornado in Washington County, Oklahoma

This is the second segment of a two-segment tornado. After crossing into Washington County, it moved just north of east, and dissipated east of Highway 75 and south of the 2500 Road. The tornado damaged outbuildings, uprooted trees, and blew down power poles. Based on this damage, maximum estimated wind in this segment of the tornado was 95 to 105 mph.

Severe thunderstorms developed along a dry line over central and western Oklahoma during the afternoon of the 1st, as a strong upper level disturbance translated into the Southern Plains. The storms moved through eastern Oklahoma during the late afternoon and evening hours. Moderately strong instability combined with strong deep layer shear to support the development of some supercell thunderstorms, which produced several tornadoes, and damaging wind gusts. The storms evolved into a squall line that also produced damaging wind gusts during the late evening.
