An isolated thunderstorm developed over northwestern Oklahoma shortly before midnight of the 16th in response to a moderately unstable environment and an upper level trough. The thunderstorm back built to the northwest and entered the Texas Panhandle shortly after midnight. Other thunderstorms developed south of this thunderstorm and began moving to the south. Precipitable Water values on the upper air sounding in Amarillo, Texas (Potter County) showed near average values for this time of year. However, the thunderstorms began training over the same area over an extended period of time. This allowed for moderate precipitation accumulations across the eastern Texas Panhandle. Storm total accumulation radar estimations showed that the eastern Texas Panhandle received between 1.5 inches to near 7 inches of precipitation over a 10 hour period. Ground truth could not be ascertained to verify the higher end rain totals, but the highest total verified was over 4 and a half inches. Precipitation ended shortly after 8 am as the upper level trough moved over coastal Texas.
