A persistent upper level trough over the western United States allowed for another day of convective development across the South Plains of West Texas. Although strong large scale lift was not anticipated on the afternoon of the 24th, widespread severe thunderstorms developed under a very moist and unstable atmosphere. A quasi-stationary warm front began to move northward during the morning hours with a dryline mixing into the South Plains from the west. Very high surface dew points in the warm sector allowed mixed layer instabilities to climb to values greater than 3000 J/kg. Thunderstorms easily blossomed under these conditions and produced widespread hail up to the size of golf balls, in particular, across Lubbock County. The presence of the quasi-stationary front and dryline allowed thunderstorms to train over many areas. The most devastating flooding was observed in Crosby County where numerous roads became flooded and impassable. Flooding was also extreme in Lubbock County where many vehicles became stranded in flood waters on the south side of the city of Lubbock. Late in the evening, a home of a NWS cooperative weather observer became partially inundated by flood waters due to training of thunderstorms. One thunderstorm took on supercell characteristics while moving across Motley County. Although no tornadoes were observed, several severe wind gusts were reported by the Texas Tech University West Texas mesonet and a NSSL mobile mesonet. These winds also caused numerous power poles and trees to be downed in Roaring Springs.
