May 29 Severe Thunderstorm Event Summary...Isolated to scattered thunderstorms erupted east of a southwest-to-northwest oriented frontal boundary that was stationary over the central South Plains of west Texas during the mid afternoon hours on Memorial Day. Although the storms were initially non-severe, several outflow boundaries surged west from the convection and intersected the frontal boundary over Lubbock and Lynn Counties. As instability increased during the late afternoon hours, strongly towering cumulus clouds stretched pre-existing spin in the low levels of the atmosphere near the boundary interactions and resulted in at least three non-supercellular tornadoes. One tornado was highly-visible in southeastern Lubbock. The tornadoes were weak (F0), and no damage was reported by local authorities.The thunderstorms continued to intensify over the eastern South Plains during the late afternoon and early evening hours. Several storms eventually became severe with large hail up to the size of quarters and wind gusts up to 64 MPH.
