A short-lived, but intense heat spell with highs of 102 to 108 came to an abrupt end late this evening as active northwest flow overspread the region. Isolated, high-based supercell thunderstorms erupted first near the U.S. Highway 83 corridor from Childress south to Aspermont, with even more intense supercells occurring later over the western South Plains. Some of these storms produced giant hail of 3 to 4 inches in diameter causing severe damage to crops, buildings and vehicles. Cities hit especially hard included Childress, Amherst, Littlefield, and Anton where combined property damages may exceed $10 million with regional agricultural losses approaching $50 million.  Toward midnight CST, individual storms grew more linear over the southern South Plains before exiting southeast of the region before daybreak on July 1st.

Reported by: Trained Spotter

An intense, slow-moving supercell tracked slowly southeast along and near U.S. Highway 84 causing significant damage along its 28-mile path, particularly in Amherst and Littlefield. Wind driven hail as large as softballs devastated home siding, shattered windows, punctured roofs in homes, and severely damaged vehicles.  An estimated 1500 homes and buildings in Amherst and Littlefield sustained moderate to severe hail damage, with many rural homes and outbuildings also affected. Financially, the greatest losses were dealt to approximately 50,000 acres of corn, cotton and sorghum.  Those crops that avoided the worst hail succumbed to torrential rains, flooding and wash outs.  Total crop losses are estimated at approximately $20 million. Many farmers were determined to replant with 90-day corn or sorghum.

This is the continuation path of the devastating supercell that moved slowly southeast along U.S. Highway 84 from Lamb County. Wind-driven hail as large as baseballs shattered home windows, destroyed siding, punctured roofs, heavily damaged vehicles, wiped out crops, and stripped trees across far northeast Hockley County.  The mayor of Anton described the hail damage as the worst he had ever seen in decades of living on the Texas South Plains and declared a state of disaster. The American Red Cross said 100% of the roughly 400 homes in Anton sustained serious damage, with each home requiring on average $6,000 of repairs.  One resident of Anton was bruised by the large hail and cut by broken glass as he attempted to cover up shattered windows during the storm.  About 8,000 acres of crops in extreme northeast Hockley County were a total loss from the hail, torrential rainfall and flooding that ensued.

This is the continuation path of the devastating supercell that affected Lamb and far northeast Hockley Counties. Wind-driven hail up to the size of tennis balls devastated area crops and caused moderate to heavy damage to about 100 rural homes in far northwest Lubbock County, generally northwest to just northeast of Shallowater. The heaviest toll was inflicted to roughly 40,000 acres of cotton, sorghum and corn which became a total loss after heavy rains and flooding eroded the young plants.  Fortunately, the supercell storm dissipated northwest of Lubbock in response to a line of storms developing immediately to its southeast.
