A very moist and unstable atmosphere developed on the 13th ahead of an approaching upper level short wave. Virga showers had developed out ahead of this upper level feature during the morning and early afternoon. This caused a severe wind gust to 65 mph from a heat burst at the Texas Tech University West Texas mesonet site near Graham (Garza County). When thunderstorms developed in the late afternoon, the initial activity was somewhat disorganized. But these initial storms were intense enough to produce pockets of hail as large as ping pong ball size. Eventually the scattered thunderstorms amalgamated into a line and accelerated eastward through the Rolling Plains and into western North Texas during the late evening hours. Several reports of small hail, strong to severe wind gusts and very heavy rainfall were received as the line moved through.
