The episode as NWS LUB wrote it up.
A couple rounds of severe thunderstorms occurred on the evening of the tenth. A stalled out outflow boundary was located from roughly Vigo Park (Swisher County) to Jayton (Kent County). Enhanced upslope flow along the edge of the caprock and strong instabilities generated an isolated severe supercell in Swisher County producing hail up to quarter size. The second round of severe thunderstorms initiated in eastern New Mexico and moved into the South Plains late in the evening hours. A southerly low level jet enhanced moisture advection and elevated instability allowing these storms to persist across the region. Severe thunderstorm winds were reported in Parmer County and Garza County along with wind damage in Hall County.

Area Forecast Discussion National Weather Service Lubbock TX 613 PM CDT Sun Sep 10 2023 ...New AVIATION... .SHORT TERM... (This evening through Monday) Issued at 226 PM CDT Sun Sep 10 2023 Today is likely our final day with highs in the 90s for quite some time thanks to a potent cold front arriving tomorrow. Until then, we'll see occasionally breezy southerly flow ahead of a surface trough stretching from CNM-CVS-GUY. Of equal interest is a subtle outflow boundary stalled roughly from near Vigo Park southeast to Jayton. LAPS analysis at 1 PM reveals an axis of healthy SBCAPE approaching 3000 J/kg immediately west of this outflow boundary with CIN slowly diminishing. Enhanced upslope ascent along the edge of the Caprock in Briscoe County is already breeding some cumulus which may eventually give rise to isolated storms later this afternoon. A greater coverage of precip should emerge farther west with the approach of a subtropical jet max from eastern NM. This feature has been aiding in a N-S axis of mostly elevated showers across the western South Plains that may become surface based with time as it drifts farther east. Deep layer shear will be improved over yesterday and DCAPEs will again be favorable for downbursts. PoPs were capped to chance mention this afternoon given rather weak forcing available, although likely PoPs seem more justified overnight off the Caprock where a southerly LLJ will enhance moisture advection and elevated instability. This area is already within a moist tongue and will see its PWATs rise to just over 1.5 inches tonight. Provided deep convection spreads S-SE from the TX Panhandle tonight, this moist fetch could easily fuel some swaths of heavy rain across our northeast zones which could linger through the morning hours. A cold front meanwhile will cruise through the TX Panhandle tomorrow morning before slowing over the South Plains and Rolling Plains during the day. Wouldn't be surprised to see this front cover more real estate particularly if larger convective outflows develop, although for now the NBM seems reasonable with the front clearing the CWA by late afternoon. We continue to side with the cooler highs shown by the NBM's 25th percentile. Highs still have room to go lower, particularly over the northern half of the CWA where low clouds will become more prevalent through the day. Lastly, the NBM's drier PoPs on the Caprock tomorrow fit well with the lack of deeper saturation and lift that is favored to reside farther north under an upper jet and shortwave trough. These two features will contribute to a persistent, zonal band of mid and upper moisture that will eventually edge closer to our area after tomorrow. && .LONG TERM... (Monday night through next Saturday) Issued at 226 PM CDT Sun Sep 10 2023 Broad upper level diffluence will continue through the late evening hours Monday into early Tuesday as an H3 jet streak pivots over the TX Panhandle and a progressive series of midlevel shortwave disturbances shifts overhead within WNW flow aloft. This will allow for the continuation of numerous showers and storms on Monday night, particularly across the Rolling Plains where PWATs are progged to exceed 1.5 inches. There is some concern that the most widespread convective coverage may end up south of our area across the Permian Basin in closer proximity to the focusing effects of the remnant surface front, and for this reason have nudged PoPs a bit downward during the early morning hours on Tuesday, however scattered showers do still seem like a good bet across most of the region through Tuesday morning given the impressive moisture and continuation of forcing aloft. Tuesday is also expected to be the coolest day of this week with a blanket of low cloud cover likely to persist through most of the day keeping highs in the upper 60s to mid 70s. After a relative lull in precip on Tuesday, an additional round of more widespread showers is expected Tuesday night into early Wednesday as a belt of stronger midlevel flow descends over the region. Once again, there is uncertainty on exactly where the highest coverage of precip will be during this period given a more muddled surface pattern, but coverage is still expected to be high enough to support likely to categorical PoPs areawide through early Wednesday. Chances for showers and storms will remain fairly high through late week as a train of modest shortwave disturbances transits overhead the moist low level airmass. Deterministic and ensemble guidance highlight the Wednesday night into early Thursday period for an additional round of numerous showers and a few storms as PWATs potentially approach 1.75 inches off the Caprock in tandem with a well-timed shortwave. Forecast confidence decreases Thursday through Friday as guidance suggests the airmass will begin to dry slightly as midlevel flow obtains a more dominant westerly component. Flow aloft overall looks to weaken Thursday and Friday as a broad midlevel low descends over the southern Rockies, but will maintain chance PoPs during this period as upslope surface flow continues and PWATs remain above one inch. This low will then eventually shift over the central plains bringing a return of stronger NW flow aloft and a continuation of precip chances through next weekend. Temperatures will remain below average throughout the extended forecast. && .AVIATION... (00Z TAFS) Issued at 613 PM CDT Sun Sep 10 2023 TSTMs will be possible this evening across the region, potentially affecting KCDS, KLBB, and KPVW. TSTM coverage is expected to be scattered, and, therefore, have handled it with TEMPOs at all terminals. Severe-caliber surface wind gusts and hail up to 2.5 inches surface-to-aloft is most probable at KCDS and perhaps KPVW, with lesser intensity INVOF KLBB tonight. VFR will prevail outside of convection. SHRA returns late tomorrow afternoon and beyond the scope of this TAF period. Sincavage && .LUB WATCHES/WARNINGS/ADVISORIES...
