The Texas Panhandle was firmly locked in northwest flow aloft on the 7th. This type of weather pattern favors the development of precipitation across the Panhandle as it allows weak shortwave troughs to dive southeastward from the Continental Divide into the Southern Plains. The large scale lift provided by one such shortwave during the afternoon hours of the 7th coupled with marginal elevated instability to develop scattered thunderstorms across the northern Texas Panhandle. Initially these storms were near stationary due to weak mid-level steering winds. However, elevated instability values were high enough to produce an isolated severe thunderstorm. As the 6 PM CST hour approached, scattered thunderstorms began moving to the southeast as the shortwave approached and steering flow strengthened. Discrete thunderstorms across the eastern half of the Texas Panhandle increased in intensity while moving to the southeast as they moved into areas of slightly higher instability values. These thunderstorms produced varying sizes of hail and heavy rain before diminishing around the 7 PM CST hour. Discrete thunderstorms over the western half of the Texas Panhandle began merging into a line while moving to the south-southeast. Once congealed into a linear structure, these thunderstorms moved across the western half of the Texas Panhandle producing damaging wind gusts and heavy rain. These thunderstorms quickly diminished after 10 PM CST as the upper level shortwave which initiated these storms moved into central Texas.
