A series of three supercell thunderstorms impacted the central South Plains of west Texas during the late afternoon and evening hours of the 19th. The initial storm erupted near the intersection of a dryline and warm front over Hockley and Lubbock Counties shortly before 17:00 CST.  This storm quickly became supercellular, and produced large hail and a brief tornado as it tracked east-northeastward over southern Hale and Floyd Counties.  Additional supercells developed near the same surface features through the evening hours.  One storm produced a swath of damaging hail over portions of Lubbock County, including near Shallowater where very large hail up to the size of baseballs was reported.
