EF1 tornado in Palo Pinto County, Texas

Using radar imagery in combination with eyewitness accounts (videos and pictures), a confirmed EF1 tornado formed over Possum Kingdom Lake around 3:12 PM CDT. The tornado then tracked onshore near Upper Burma Rd, where trees sustained such damage as snapped trunks and large broken branches. As it crossed the peninsula, roof damage to single family homes and nearby small metal buildings was observed, consistent with 95 mph winds. The tornado then tracked back over the lake before causing more sporadic damage on the northeast shore of Possum Kingdom Lake. The tornado lifted at 3:26 PM CDT just northwest of Stoney End Ln. The maximum estimated winds were 95 mph.

A strong shortwave trough aided in the development of scattered to numerous thunderstorms during the late morning, afternoon, and evening hours of March 21. Thunderstorms initially fired along a dryline, many of which became severe, and some of which produced strong tornadoes. A total of 17 tornadoes were confirmed by storm survey teams, the strongest of which was the EF-3 Jacksboro tornado. One death occurred in a tornado in Grayson County near the Red River.
