The episode as NWS LUB wrote it up.
Scattered thunderstorms again developed on the afternoon of the 11th as a weak upper level short wave approached the area. A deep upper level trough was able to keep a dryline backed up into eastern New Mexico this afternoon. Stronger deep layer shear was able to keep convection discrete on the 11th. One of the storms that developed generated hail up to two inches in diameter in far northern Castro County.

NWS Lubbock, TX wrote its last area forecast discussion before the first event at May 11, 6:15 PM CST, 30 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 715 PM CDT Wed May 11 2022 .AVIATION... VFR conditions will prevail through this TAF period. Thunderstorms have remain isolated this evening and these storms will not pose a threat to any TAF site. LLWS will become possible at the TAF sites late this evening into early Thursday morning as winds about 800 ft AGL increase to 40 kts. && .PREV DISCUSSION... /issued 228 PM CDT Wed May 11 2022/ SHORT TERM... Scattered showers and thunderstorms will once again be possible today over the South Plains and the southern Texas Panhandle. Water vapor imagery early this afternoon shows a weak upper disturbance near El Paso moving to the northeast towards the region. At the surface, southeasterly winds have kept dewpoints in the 50s and 60s across the CWA, with a dryline noted over eastern New Mexico on LAPS and the West Texas Mesonet. Comparing 1820Z ACAR sounding out of KLBB to recent runs of CAMs valid at 18Z indicated that CAMs are currently underestimating MLCAPE/MUCAPE over the city (and potentially over the area) by 500-1000 J/kg. CAMS may just be a little slow to advect instability into the area as they begin to increase instability over the region later by 19-20Z. Recent visible satellite imagery shows a CU field forming over the south-central Texas Panhandle and eastern New Mexico, which indicates increasing instability over the region. As convergence increases along the dryline and the disturbance moves near, storms should begin to fire near the TX/NM state line between 21-23Z (4-6 PM). If storms fire, they will have a better chance to remain discrete for areas near the South Plains than yesterday as they will have a slightly more eastward storm motion and deep- layer shear ~25 kt. These storms will move into an area of 2000-2500 J/kg of MLCAPE and ~1500 J/kg of DCAPE. With storms moving into this environment, they will be capable of producing hail up to the size of golfballs and wind up to 75 mph. Storms that form near the southwestern Texas Panhandle will be in a similar environment but will have a similar trajectory as yesterday, so they are expected to congeal/cluster and have more of a wind threat, but a threat of large hail will still exist. With storms forming mid to late-afternoon and moving slowly to the northeast, they will struggle to make it too far east before surface warming decreases and the atmosphere begins to stabilize. The main upper low, currently over the western CONUS, will be over the north-central Plains tomorrow. This will allow the dryline to mix east tomorrow as a cyclone forms near the Rockies, resulting in downslope winds over eastern New Mexico and the South Plains. This will bring fire weather concerns to the area for the South Plains and southwestern Texas Panhandle for the day tomorrow. Storms may form off the dryline near the Caprock tomorrow afternoon, but the upper trough appears too far north to allow for much upper-level support. GKendrick LONG TERM... An upper low pushing northeastward across the Northern Plains tomorrow evening will push a weak cold front into the region tomorrow night into Friday morning. The front is progged to stall across/near our southern zones by sunrise Friday and remain in place through at least late Friday afternoon. The surface front could be a trigger for convective development late Friday as a weakness moves across the northern edge of an upper ridge that is beginning to build northward from Mexico. Overall upper forcing will be limited as will storm coverage. Currently the southern Rolling Plains is favored for convection, but this will be dependent on where the front stalls. Storm propagation will be south to southeastward. While the severe threat would be minimal, the biggest threat would be severe wind gusts as well as localized flooding. The aforementioned upper ridge will continue to build from northern Mexico into the Central and Northern Rockies through the weekend and will overall keep things on the quiet side. Though temps will warm into the 90s to near 100 by Sunday, the recent rainfall across the area should hopefully limit a further rise in temps as dewpoints remain slightly elevated. Models continue to hint at a possible passive backdoor cold front late Sunday into early Monday as upper troughing amplifies across the eastern CONUS. There are hints at possible isolated convection from this front late Monday, but coverage/confidence is much too low to add precip into the forecast. Any possible convection would be limited by overhead ridging. The upper ridge should be kicked eastward by mid next week as an upper shortwave trough flattens the upper flow and brings possible dryline convection to the region. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && 58/10/51
Hazardous Weather Outlook National Weather Service Lubbock TX 1102 AM CDT Wed May 11 2022 TXZ021>044-121615- Parmer-Castro-Swisher-Briscoe-Hall-Childress-Bailey-Lamb-Hale-Floyd- Motley-Cottle-Cochran-Hockley-Lubbock-Crosby-Dickens-King-Yoakum- Terry-Lynn-Garza-Kent-Stonewall- 1102 AM CDT Wed May 11 2022 This Hazardous Weather Outlook is for the South Plains, Rolling Plains, and the far Southern Texas Panhandle. .DAY ONE...Today and tonight. Scattered thunderstorms are expected to develop immediately to the east of the dryline by mid afternoon and favoring areas along and either side of the New Mexico state line. Storms that form will initially move to the northeast but with a greater eastward component into the evening hours. A slight risk for severe weather exists to the west of a I-27/US-87 line. The main threats will be hail to the size of golfballs and wind gusts to 75 mph. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday. Severe thunderstorms will again be possible during the late afternoon and evening hours Thursday and Friday mainly to the east of the Interstate 27 corridor. .SPOTTER INFORMATION STATEMENT... Spotter activation may be needed.
