The end of August brought several rounds of thunderstorms to the South Plains region, beginning on the Sunday afternoon and evening (28 August). Hot temperatures, peaking in the 90s and lower triple digits, in combination with an influx of moisture, fueled widely scattered thunderstorm development Sunday afternoon. The storms that formed were particularly electric, producing proficient cloud to ground lightning, gusty winds and localized heavy rain. |

One storm was particularly intense as it moved over Tahoka, dumping a load of rain and producing strong outflow winds. The lightning and wind knocked out power to many in and around Tahoka, while the quick 2 to 4 inches of rain that fell produced extensive street flooding. |

The following day (Monday, 29 August) brought more widespread and intense thunderstorms, triggered in part by an upper level disturbance approached via the southern Rockies. Greater instability than the previous day led to rapid thunderstorm development Monday afternoon across the southwest Texas Panhandle and northwestern South Plains. This activity quickly grew into a line as it accelerated south and southeastward through the evening hours. Along the leading edge of the line, intense winds lofted a wall of dust (known as a haboob), dropping the visibility to near zero for a short time in many spots. Unfortunately, the haboob did contribute to several vehicle wrecks, including a two fatality accident near Roscoe, Texas. | |||||

The strongest wind gusts, from 45 to 60+ mph, swept southward across the Caprock through early Monday evening, before shifting down into the Permian Basin and Big Country. A peak wind gust of 73 mph was measured by the West Texas Mesonet site 6 miles south-southwest of Anton. Lagging the wind, many spots experienced a period of heavy rain, followed by prolonged light to moderate rain through the late evening hours. | |||||

The already rich moisture levels continued to improve through the final two days of August, adding even more "fuel" for potential showers and thunderstorms. Indeed, this "fuel" was tapped by a slow-moving upper level low that took shape over Far West Texas, resulting in additional rounds of heavy rain. | |||||

The showers and thunderstorms that developed on August 30th (Tuesday) were less intense than the previous day in terms of amounts of lightning and strength of the wind gusts they generated, but they did produce torrential downpours as they moved westward across the South Plains and Rolling Plains. The tropical-like downpours resulted in excessive runoff and created pockets of flooding Tuesday afternoon and evening before diminish after sunset. | |||||

The upper level storm system became nearly stationary, centered close to El Paso (see the below animation), which allowed extremely humid air to continue to be pumped up into West Texas on Wednesday (31 August). The near record moisture levels, along with the nearby upper level low and weak daytime heating, initiated another round of westward-moving showers and thunderstorms that dumped additional torrential rain in spots Wednesday afternoon. | |||||

One relatively small shower that developed over Lubbock early Wednesday afternoon unloaded 0.50 to 1.50+ inches of rain in a matter of minutes, creating widespread street flooding. | |||||
Ominous clouds over Lubbock just after 1 pm on Wednesday afternoon (31 August). The shower dropped a quick inch or more of rain over parts of Lubbock in the matter of minutes. | |||||
The torrential rain wasn't confined to Lubbock, but affected a good portion of the South Plains and Rolling Plains, with more isolated downpours across the southern Texas Panhandle. Instantaneous rainfall rates as high as 4-6+ inches an hour were common with the strongest cores. Thankfully, most of the activity moved steadily westward, but they were still able to 1 to 2+ inches in many spots before ending. | |||||

In addition to causing flooding in and around Lubbock, Brownfield and Post, a couple of the tropical showers generated brief funnel clouds, as seen in the below image on the left. These "tropical-type funnels" did no known damage, but did further enhance the already ominous skies. | |||||

The below map displays the measured rainfall over this wet late-August stretch. Rain totals of 1 to 3+ inches were common, except across the southeast and southwest Texas Panhandle and a few spots in the Rolling Plains, where rain was generally lighter. A number of locations across the South Plains into the western Rolling Plains recorded over 3 inches, including an impressive 4.45 inches in Tahoka and 4.77 inches at White River Lake. Although excessive at times, the rain helped mitigate the ongoing drought. | |||||
