From late on the 14th through the early morning hours on the 15th, severe thunderstorms brought torrential rainfall, large hail, and several swaths of severe winds. Thunderstorms were initially isolated to widely scattered on the evening of the 14th. Sufficient vertical wind shear allowed some of the storms to rotate becoming supercells and tracking southeastward. The most intense storm developed in the southwest Texas Panhandle and tracked down US Highway 84 through Lubbock (Lubbock County). This storm produced golf ball size hail in Earth (Lamb County), 60 mph winds near Amherst (Lamb County) and wind damage in Anton (Hockley County). This same supercell went on to produce several observed severe wind gusts across central Lubbock County and damage on the campus of Texas Tech University. Following the evening supercell, a large complex of thunderstorm moved out of eastern New Mexico and across much of the South Plains and Rolling Plains through the early morning of the 15th. This complex of thunderstorms generated very intense winds as it approached and moved across Lubbock (Lubbock County) and Slaton (Lubbock County). A peak gust of 78 mph was measured by the Texas Tech University West Texas mesonet site in Slaton shortly after the storms produced wind gusts up to 69 mph within the city of Lubbock. The severe winds downed numerous large limbs and trees and damaged several roofs in and around Lubbock as they raced through. This large area of thunderstorms produced torrential rainfall as it moved through. The heaviest rain from this event was also focused where the strongest wind occurred, from Lubbock through Slaton and southwest Crosby County. Much of the rain fell in less than a half hour which led to extensive runoff and flooding. The runoff was directed down the North Fork Double Mountain Fork of the Brazos River downstream of Lubbock. Even well after the rain concluded many low spots and drainages were inundated with water and several roads were closed.
