The episode as NWS LUB wrote it up.
Early on the seventh a cold front moved through the region bringing cooler temperatures to the area. This front then retreated back northward as a warm from during the daytime. Strong instability south of the front and a weak short wave trough aloft contributed to scattered thunderstorms from late afternoon through the evening. One of these storms developed a wet microburst as it moved across Terry County. A vineyard to the northwest of Brownfield (Terry County) sustained damage from this wet microburst. A center pivot irrigation system was destroyed and some crops were damaged.

Area Forecast Discussion National Weather Service Lubbock TX 654 PM CDT Mon Aug 7 2023 ...New AVIATION... .SHORT TERM... (This evening through Tuesday) Issued at 250 PM CDT Mon Aug 7 2023 The passing of the cold front early this morning gave way to cooler temperatures and moisture today. Aloft there is a west-northwest flow with an embedded shortwave moving out of the Southern Rockies. Satellite imagery is showing convective development occurring in New Mexico currently with this area of lift. The convection is expected to grow as it moves east through New Mexico and into our area. MLCAPES will be around 1500-2000 J/kg. Deep-layer shear should be improving as stronger mid-level winds arrive on the southern flank of a belt of 40-50kt winds at 500 mb centered over the panhandles. This will result in 30-40kts of shear over the CWA. This environment will support some vigorous storm growth and lead to a severe thunderstorm threat. The primary threats will be damaging wind gusts. However, there is some hail threat, especially in the early stages of thunderstorm evolution. Scattered thunderstorm activity will consolidate into a thunderstorm complex that will move eastward cross much of the forecast area tonight into the early hours Tuesday. In addition to the severe threat, there could be some pockets of heavy rainfall. Even in the wake of the MCS, continued lift due to the energized westerly flow along with some warm advection on the low-level jet should generate some additional shower and thunderstorm activity through the morning hours although the coverage of this activity is uncertain at this time. Any lingering activity should end by late Tuesday morning. The upper ridge will remain suppressed to our south tomorrow with westerly flow aloft. The return of southerly low-level flow should temperatures rebound back into the upper 90s to 105 or so for afternoon highs. Forcing for convective development tomorrow afternoon looks a littler more nebulous than today but the strong heating in combination with moisture and perhaps some weak ripples in the westerly flow aloft will likely support some thunderstorm chances by late afternoon mainly in the Rolling Plains. CR && .LONG TERM... (Tuesday night through next Sunday) Issued at 250 PM CDT Mon Aug 7 2023 Isolated-to-widely-scattered thunderstorms will be ongoing Tuesday evening across the Caprock and Rolling Plains in concert with a series of fast-moving perturbations embedded within the quasi-zonal flow ahead of a shortwave trough digging into the central Rocky Mountains. The diurnally-driven, orographically-generated convection should begin to decay shortly after the start of the period (i.e., 09/00Z or Tuesday at 7 PM CDT) as diabatic stabilization occurs, though convection and/or showers may linger into the early morning hours across portions of the South Plains as it becomes elevated. Early on in the evening/prior to boundary-layer decoupling, the strongest storms will be capable of producing strong wind gusts in excess of 50 mph given the Inverted-V profiles. Otherwise, the severe weather threat remains low heading into Tuesday night. Prevailing winds outside of the decaying convection will gradually veer to the southwest during the overnight hours while remaining breezy as the surface trough sharpens in response to the ejecting shortwave trough over the west-central Great Plains. Temperatures, therefore, will be very warm heading into Wednesday morning (another contribution being the residual cloud debris inhibiting the escape of longwave radiation) across the CWA where lows near 80 degrees across portions of the Rolling Plains whilst a few degrees cooler west of the escarpment edge. Surface flow will veer nearly 180 degrees in direction from the southwest-to-north as a lee cyclone to the northeast of the CWA moves southeastward along an incoming cold front associated with the compact shortwave trough ejecting eastward over the State of Oklahoma. Adiabatic compression associated with the westerly wind component during the day will completely mix out the boundary-layer with high temperatures peaking near 105 degrees across portions of the South Plains to near 108 degrees in the Rolling Plains. The blended temperatures were increased a few degrees to align with the recent MOS guidance on Wednesday as mixing heights ascend past 600 mb by peak heating. Fortunately, the passage of what will be a dry front will knock morning temperatures down approximately 3-5 deg F heading into Thursday morning compared to the prior morning, with the extreme southwestern TX PH hitting the jackpot with middle 60s expected as winds continue to veer to the east as a weak surface ridge develops in the wake of the ejecting shortwave trough. The progressive wave train is forecast to shift poleward towards the latter half of the week as subtropical ridging expands across the Gulf of Mexico, and into the southern Great Plains and the Desert Southwest. Global NWP guidance is indicating that the remnants of Tropical Storm Eugene in the northeastern Pacific Ocean evolves into a cutoff low off of the coast of California by the start of the weekend. The presence of this cutoff low well to our west, in conjunction with the western tranche of the subtropical ridge eclipsing the southern Rocky Mountains, should re-activate the monsoonal fetch and advect it towards the southern Rocky Mountain Piedmont. It appears that the best potential for monsoonal thunderstorms will be west of the edge of the Caprock Escarpment (i.e., areas nearest the monsoonal fetch); however, given that this is in the D5-D8 period, the broad brushed PoPs generated by the NBM have been left intact due to the agreement among the global NWP guidance on the evolution of the aforementioned synoptic features. Temperatures will gradually trend downward over the weekend into early next week as well in conjunction with the return of the monsoon to the west of the region. Sincavage && .AVIATION... (00Z TAFS) Issued at 621 PM CDT Mon Aug 7 2023 Currently, satellite and radar imagery shows isolated thunderstorm development across the CWA as convection to the west of the TX/NM state line track east. Thunderstorms are expected to affect KLBB and KPVW terminals this evening into overnight with periods of reduced visibility from heavy rainfall. Moreover, periods of gusty and erratic winds will be possible with stronger storms. Confidence is not as high for thunderstorm activity to affect KCDS, however, the potential is high enough to mention a VCTS in the TAF. The main round of storms is expected to end by 04Z at KLBB and KPVW, but lingering isolated storms will remain possible overnight. Tomorrow morning, an outflow wind shift is possible for KCDS as a MCS tracks southwest through OK. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && SHORT TERM...10 LONG TERM....09 AVIATION...12
