During the third week of September, an unusually moist and unsettled pattern overspread much of West Texas. The majority of this moisture was sourced from the remnants of Pacific Hurricane Odile and contributed to multiple waves of slow-moving showers and thunderstorms punctuated by periods of flooding. The most extensive flooding was noted during the morning and afternoon of the 18th from the northern South Plains into portions of the western Rolling Plains where several inches of rain fell in the span of mere hours. By late morning on the 18th, TxDOT reported that numerous roads had flooded sections and in some cases temporary road closures were required due to standing water and thick mud. Although not as widespread, additional flooding was noted on the 20th and 21st generally from Terry County east to Garza County. Radar derived precipitation indicated as much as 10 inches of rain fell across southeast Terry County on the 20th. In total, much of the South Plains saw widespread 2 to 4 inch rainfall this week with the lightest amounts of one half inch or less confined to portions of Hall and Childress Counties.
The heavy rainfall was of significant benefit to many area lakes and reservoirs. Lake Alan Henry saw a 9-foot rise to its highest level recorded since November 2012. White River Lake's smaller watershed still managed to push its water level to the highest seen there since early 2013. Unfortunately, the cool and wet weather was detrimental to the regional cotton crop as projected yields were reduced by at least a half a million bales; however, the improved deep soil moisture raised prospects for winter wheat planting in the months ahead.
Although rainfall as great as 15.26 inches fell in nearby Borden County, below are some official five-day rainfall totals from the NWS Lubbock forecast area from September 17th through the 21st. Except where noted, all amounts are from Texas Tech University West Texas Mesonet stations.
