Scattered showers and thunderstorms developed along a surface trough draped across the southern Texas Panhandle during the afternoon hours of the 12th. These thunderstorms moved very slowly and stayed over one area for a prolonged period of time. This slow movement coupled with unseasonably high Precipitable Water values of 1.4 inches lead to periods of heavy rain across the southern Texas Panhandle. In the most intense downpours, visibility was greatly limited which made traveling on local roadway extremely difficult and dangerous. The surface trough which provided the focus for thunderstorm development moved south of the Texas Panhandle by 6 PM CST which lead to the dissipation of precipitation across the panhandle.
