Numerous slow-moving thunderstorms erupted this afternoon in the southern Texas Panhandle along a weak cold front, before spreading south through the South Plains and Rolling Plains throughout the evening. Some of these storms redeveloped over the same areas, most notably in central Swisher County where Tulia and the nearby Middle Tule Creek experienced flash flooding from over four inches of rain in less than one hour. In Hockley County, a favorable merger of outflow boundaries supported a rotating thunderstorm that produced a swath of damaging winds and flash flooding. In addition to damaging several power poles and a Texas Tech University West Texas Mesonet, this storm produced incredible rainfall rates measured as great as 0.69 inches in 5 minutes, or 8.28 inches per hour.
