Early in the morning on the second, a mesoscale convective system (MCS) moved southeastward out of the Texas Panhandle into the South Plains. This MCS maintained its intensity as it reached the Rolling Plains and began to develop a mesoscale convective vortex (MCV) on the north side of a bowing line segment.

The episode as NWS LUB wrote it up.
Early in the morning on the second, a mesoscale convective system (MCS) moved southeastward out of the Texas Panhandle into the South Plains. This MCS maintained its intensity as it reached the Rolling Plains and began to develop a mesoscale convective vortex (MCV) on the north side of a bowing line segment. As this occurred, a couple of severe thunderstorm wind gusts were observed by the Texas Tech University West Texas mesonet.

NWS Lubbock, TX wrote its last area forecast discussion before the first event at Jun 2, 1:07 AM CST, 3 hours 27 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 207 AM CDT Wed Jun 2 2021 .SHORT TERM... The active period of weather continues across West Texas today. The first round will be a linear feature moving out of the Texas Panhandle early this morning. Have increases POPs before sunrise to account for this likelihood. Evident in the system appears to be an MCV trying to get going across Deaf Smith county as of 130AM. A pressure perturbation out ahead of the line is generating a few showers in advance of the main system. Just how long this feature will stay together is a good question, but it wouldn't be surprising for it to move much of the way through the CWFA by sunrise. This morning's activity is being driven by positively tilted trough axis extending from the eastern Ontario into southwest Texas. Out to our southwest, a closed low is evident across Baja California. As the day progresses, mid-level flow will largely remain northwesterly before transitioning toward northerly flow on Thursday morning. By in large, presuming the morning convection works through the area, this should help stabilize the atmosphere to some degree and should decrease rain chances until daytime heating sparks some scattered activity late this afternoon. CAPE of around 2kJ looks to be reasonable, as indicated in some of the forecast soundings along with about 30 KTS of bulk shear. However, the sub-cloud layer wind fields are very anemic (below about 750 mb) and quite dry to boot. Hail doesn't look to be too much of a threat this afternoon, but downburst winds do and we'll call for 65 mph gusts in the HWO. This initial activity should wane with the loss of daytime heating. However, at the same time, a line of convection should become established along the Pecos River Valley and move eastward during the evening. It appears the southwestern South Plains will have the best shot at getting another dose of rainfall as it moves out of NM. Instability should remain moderate above the low level inversion. This should allow the system to remain intact as it propagates through the region exiting the CWFA perhaps around 07Z if all goes according to plan. This rarely happens in reality, but it's a good faith effort. Forecast soundings would suggest the evening/overnight activity should be more of a rain event rather than severe given strong decoupling of the boundary layer and a rather ectomorphic CAPE profile. .LONG TERM... Little change has been necessitated for this morning's forecast package as the previous assessments remain largely on track. A cutoff low, now centered over Baja California, will gradually drift eastward throughout the end of the work week as a high-amplitude, mid/upper-level ridge builds into the western U.S. A weak vorticity lobe is forecast to rotate equatorward along the southern stream portion of the ridge axis, resulting in diurnally-driven convection across portions of the South and Rolling Plains on Thursday a afternoon. Deep- and cloud-layer flow is expected to be weak, with small, compact hodographs favoring single- and multi-cellular storm characteristics. The potential for storms becoming severe on Thursday is low; however, a rogue gust up to 50 kt and hail up to 1" in diameter will be possible given the presence of a modest EML of around 1,500 J/kg and a well-mixed sub-cloud layer. The potential for convection remains low throughout the weekend as the lack of any viable surface convergence amidst weak synoptic- scale forcing for ascent precludes organized development. While the boundary-layer will be quite moist over the weekend with a diffuse dryline developing across eastern New Mexico, it is forecast to remain anchored along the Mescalero escarpment due to the former statement (i.e. weak large-scale forcing as the broad, cutoff low moves east into the southern Great Plains preventing propagation of the dryline despite ample heating). A gradual increase in geopotential heights is expected heading into early next week as a sub-tropical ridge builds into the southwestern Great Plains, with temperatures rising into the upper 80s to lower 90s by the early and middle portions of next week.

A lesser risk of severe thunderstorms will also occur late this evening into the overnight hours. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday. Thunderstorm chances Thursday afternoon and evening will focus on areas near the New Mexico state line. Some of these storms could be severe, capable of producing damaging winds up to 60 mph and large hail around quarter size. Thunderstorm chances, some possibly severe, remain in the forecast for through the weekend across the Rolling Plains. .SPOTTER INFORMATION STATEMENT... Spotter activation may be needed.
