A storm system emerging from the Four Corners region, in combination with a southward sagging cold front, served as triggers for thunderstorm develop across the southern High Plains Wednesday afternoon (15 May). Although moisture levels were not particularly juicy, at least by May standards, it was sufficient to supply weak to modest instability that fueled several rounds of strong to severe thunderstorm through the evening and overnight hours.

The initial thunderstorm development occurred along a frontal boundary that extended from southwest Oklahoma into the northwestern South Plains and southeast New Mexico, as well as over the higher terrain of New Mexico and southeast Colorado. The most robust updraft cores generated pockets of hail, including hail as large as golf balls on the southwest side of Plainview.

The warm/hot conditions, with highs in the upper 80s and lower 90s, and modest moisture levels led to high-based thunderstorms. These storms were proficient at generating strong to severe wind gusts, thanks, in part, to the deep and relatively dry sub-cloud layer ripe for evaporative cooling. Many locations recorded wind gust of 40 to 50+ mph as the storms approached and moved through, with several wind gusts near and above 60 mph measured. A peak wind gust of 78 mph was measured by the West Texas Mesonet site on the south side of Plainview at 4:32 pm.
 
High-based thunderstorm and dusty outflow (dust foot) approaching Lubbock from the west at 7:10 pm on Wednesday evening (15 May 2024).

The wind kicked up dust on the leading edge of the advancing rain-cooled air, and also helped to spark additional thunderstorms as the activity propagated eastward. After a relative lull in storm coverage and intensity late evening, additional rounds of strong thunderstorms moved across the northern South and Rolling Plains through early Thursday morning.

Despite the limited moisture, the rain gradually moistened the sub-cloud layer, and where storms repeatedly tracked, they dropped significant rainfall. The heaviest rainfall, near and above an inch, was focused in an east-to-west swath from north of Morton to Plainview and Ralls to near Paducah, with an additional pocket east of Silverton.

The following day, Thursday (16 May) brought additional rounds of thunderstorms to the south-central United States. The heaviest and most widespread rain targeted regions well downstate, over a good chunk of the center and southeast part of Texas, where they were already battling flooding in spots. Closer to home, a complex of thunderstorms rolled out of southeast New Mexico during the late afternoon, and across a large portion of the South Plains through early evening.

The heaviest rain Thursday afternoon and evening targeted the southern and western South Plains, though most locations saw at least a little additional rainfall and gusty outflow winds. Several spots did experience wind gusts to severe levels, measured as high as 68 mph at the West Texas Mesonet station north of Plains, where they also had nearly 2/3 inch of rainfall. The Denver City COOP measured an impressive 1.52 inches, surpassing their entire rainfall for the year up to that point (1.25 inches of rain fell in Denver City from January 1st through May 15th)!

The heavier rain clipped the north side of Lubbock on the 15th, including the official reporting site at the Lubbock Airport, which measured 1.51 inches. This rain boosted the year-to-date rainfall to 5.50 inches, which is a little over a half inch of normal. Unfortunately, the south side of Lubbock didn't see as much rain on the 15th, generally only recording a tenth or two, though they did record healthier totals, closer to a half inch, on the 16th.
