The episode as NWS LUB wrote it up.
On the afternoon of the second, scattered thunderstorms developed in eastern New Mexico and moved into West Texas during the evening hours. Additional thunderstorms developed in far southeastern New Mexico ahead of this activity. However, both complexes of thunderstorms combined into a single mesoscale convective system (MCS) as it moved across the South Plains. This MCS developed a small bowing segment which produced severe winds in Hockley County.

NWS Lubbock, TX wrote its last area forecast discussion before the first event at Jun 2, 5:20 PM CST, 2 hours 39 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 620 PM CDT Wed Jun 2 2021 .AVIATION... A complex of thunderstorms currently over New Mexico will move into the region late tonight into early Thursday morning. Some of these storms could affect the KLBB terminal with a smaller chance at hitting the KPVW terminal. There is not a clear signal for low CIGS to develop again Thursday morning so mention was left out of the TAF. && .PREV DISCUSSION... /issued 244 PM CDT Wed Jun 2 2021/ SHORT TERM... Showers and thunderstorms are expected to develop later this afternoon and evening and move into the area. There are currently three areas of focus, which include an outflow boundary near Yoakum and Terry counties, and higher terrain over southeastern and northeastern New Mexico. At 18Z, visible satellite imagery indicated a CU field developing off of the aforementioned outflow boundary and moving east over Yoakum and Terry counties. This field is forming within an environment with MLCAPE of 1000-1500 J/kg and deep-layer shear ~ 40 kt. If CAPE can be realized and this field starts to convect, storms will be capable of producing quarter-sized hail and wind up to 60 mph. Ahead of the next round of thunderstorms expected to move in by late evening, MLCAPE values over the southern South Plains, and Rolling Plains are expected to increase to around 2500 J/kg. As storms from northeastern and southeastern New Mexico moves into the area, they are expected to combine into an MCS. However, storms may briefly be multicellular as they enter the area, which could result in the potential of marginally severe hail and winds as they move into our western column of counties. As storms begin to combine, the threat will become mostly wind. In addition to the potential of severe winds, high atmospheric water content, slow storm motion, and training could result in flooding. Storms are expected to move out of the South Plains by early tomorrow and should completely move east of the CWA by mid-morning. Tomorrow will be similar to today in respect to cloud cover and temperature. Skies will become mostly clear for the entire area by early afternoon. Higher storm chances will be to our west as the upper-the level flow will be northerly over New Mexico. However, a cutoff low is progged to form over the area and could bring some thunderstorm chances to the southern South and Rolling Plains. GKendrick LONG TERM... The large-amplitude ridge centered over the western CONUS will finally begin to break down Thursday night, with the ridge axis quickly flattening on Friday as the trough over the eastern CONUS flattens as well. This will occur in tandem with a new, relatively compact low cutting off from a longwave trough centered over the Gulf of Alaska. This low will drift slowly westward well off the California coast Friday into Saturday while a rather broad upper low meanders over Texas through the weekend. As a result, the upper flow will transition fairly abruptly from an amplified regime late this week to an overall more neutral regime by the end of the weekend. In fact, most upper level energy will be concentrated over the far northern CONUS into Canada. With the mean flow concentrated so far north and no other significant steering flow present through much of the CONUS to help move it along, the broad upper low over Texas will linger overhead this weekend. Regarding sensible weather over the weekend, the forecast depends heavily on the position of this broad upper low. On Friday, guidance suggests the 500mb cyclonic circulation will be centered south of Midland, with easterly upper level flow overspreading the CWA. While surface high pressure to our east will continue to supply low level moisture via southerly winds and mid/upper level lapse rates will be steepening under the low center, shear will be very weak (about 10- 15 kts). With a lack of surface convergence to initiate convection, Friday is expected to remain mainly dry. At this time, Saturday appears that it will evolve in a similar manner to Friday, with a mainly dry forecast as the upper low remains in place and only shifting slightly east. On Sunday, the upper low will finally begin to lift northeastward as a larger trough begins to dive southeastward into the Pacific Northwest. As the low shifts east, upper flow over West Texas will back to northerly/northwesterly. With low level flow remaining moist from the south, the potential returns on Sunday night for upstream convection to propagate southward into the CWA. With the uncertainty in the progression of the upper low, precipitation chances are still rather up-in-the-air Sunday into Monday. Given better instability and better shear on Sunday compared to Friday and Saturday, have introduced low PoPs Sunday afternoon to account for the positioning of the upper low and the favorable environment if any storms are able to form locally. However, the forecast for this weekend is certainly subject to change given this uncertainty. Monday into the middle of next week, upper ridging will begin to build into the region from the west as the Pacific Northwest trough continues to dive southeastward. While this will result in a gradual warm-up, it will also bring a return to southwesterly upper flow. With the dryline lingering to the west, chances for thunderstorms will return each afternoon through at least the middle of the week, at this time appearing to remain mainly east of the I-27 corridor into the Rolling Plains. /DWK && .LUB WATCHES/WARNINGS/ADVISORIES...

Scattered thunderstorms this afternoon will have the potential to become severe with hail to the size of quarters and wind gusts to 65 mph. Thunderstorms are also expected to move into the area from eastern New Mexico this evening and will bring the potential of heavy rain and marginally severe wind and hail. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday. Thunderstorm chances Thursday afternoon and evening will focus on areas near the New Mexico state line into the southern South Plains. Some of these storms could be severe, capable of producing damaging winds up to 60 mph and quarter size hail. Precipitation chances are reduced on Friday and Saturday, but isolated thunderstorms are still possible. Better chances for thunderstorms return on Sunday across the area, with additional chances for thunderstorms on Monday and Tuesday. Some storms will have the potential to become severe each day. .SPOTTER INFORMATION STATEMENT... Spotter activation may be needed.
