An active round of severe thunderstorms impacted the west Texas South Plains during the late afternoon and evening of the 6th and continued into the early morning of the 7th.
Convection originated along a dryline near the Texas and New Mexico border, as well as near a pre-existing weak frontal boundary stretched west-to-east over the southwestern South Plains.
Many of the thunderstorms were supercellular in nature and produced a variety of severe weather hazards, however, splitting and low precipitation modes domininated. While these storm structures helped to limited the overall tornado threat, instances of large hail were widespread. A cluster of low precipitation supercells produced hail up to four and a half inches in diameter over portions of Lamb County. Reports of damage from very large hail also were received in the Lubbock vicinity (Lubbock County).
A supercell that interacted with the pre-existing surface boundary over the southwestern South Plains did produce a brief and weak tornado that was observed by a research meteorologist. The tornado remained in open country and resulted in no damage.
