The episode as NWS SJT wrote it up.
A strong cap on the afternoon and the evening of the 23rd prevented thunderstorm development. However, as the dryline pushed east during the late afternoon and evening it helped to initiate an isolated supercell thunderstorm near Big Springs. This thunderstorm tracked east along Interstate 20 through Colorado City, Roscoe and Sweetwater before veering north towards central Jones County. This thunderstorm produced several weak tornadoes along its path including hail to the size of baseballs.
