What happened

The episode as NWS MAF wrote it up.

A complex of strong to severe thunderstorms tracked from the Texas south plains into the northeastern Permian Basin during the late evening of the 6th. The southern storm of the linear complex was an intense high precipitation supercell. This storm produced a swath of very large and damaging hail. Thunderstorms and heavy rainfall also resulted in flash flooding in Snyder.

A high precipitation supercell moved slowly southeast across northern Dawson County during the late evening of the 6th. This storm resulted in a large swath of damaging hail ranging in size from quarters to baseballs. Most of the damage was restricted to cotton crops from the Lynn/Dawson county line near Grandview. A survey by the Dawson County Agricultural Extension Agent concluded that over 5,000 acres of cotton were lost. The storm weakened before crossing U.S. Highway 87 at Arvana where it produced only pea size hail.
