A weak mid-level trough of low pressure coupled with moderately unstable conditions across the Texas Panhandle during the evening hours of the 8th to bring severe weather. The Texas Panhandle saw both discrete thunderstorms and a line of thunderstorms over the course of a few hours. Discrete thunderstorms initiated during the early evening hours near Lubbock, where a cold front which had moved through the Panhandle the previous day had become stationary. These discrete thunderstorms moved to the north and entered the southeastern portion of the Texas Panhandle. During this same time frame, scattered thunderstorms over eastern New Mexico were slowly merging into a linear structure. Shortly after 6 PM CST, the broken line entered the western most portion of the Texas Panhandle as the discrete thunderstorms moved into over the eastern edge of the Caprock Escarpment. By 7 PM CST, the broken line of thunderstorms began producing severe level wind gusts while a discrete thunderstorm over Hutchinson County produced hail up to the size of golf balls. The line moved quickly across the Texas Panhandle reaching the central point of the panhandle around 9 PM CST. By this point discrete thunderstorms had transitioned from hail producers to heavy rain producers. The line of thunderstorms remained a severe gust producer as it moved across the panhandle. By 10 PM CST, the line moved into an area of lower instability and the effects of the nocturnal inversion became evident as the line began breaking apart.  By this point, what remained of the former line of thunderstorms transitioned to a heavy rain producer.
