The episode as NWS LUB wrote it up.
A remnant mesoscale convective vortex over the Rolling Plains coupled with a very unstable atmosphere resulted in scattered thunderstorm development over the Rolling Plains during the afternoon of the 11th. This activity developed a westward moving outflow boundary which initiated storms over the South Plains. By the evening hours, convection that had initiated over the higher terrain of eastern New Mexico was moving into West Texas. Some of these storms over the South Plains became severe producing mostly strong surface winds.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Lubbock, TX wrote its last area forecast discussion before the first event at Jun 11, 2:07 PM CST, 3 hours 3 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 307 PM CDT SAT JUN 11 2016 .SHORT TERM... Unlike yesterday when storms struggled to develop, scattered convection has had no trouble developing in a moderately unstable and weakly capped environment. Most of the development to this point was along and off the Caprock as of 1930Z, with the exception of a few cells near O'Donnell. Weak wind fields have largely limited storm organization, though MLCAPE values of 1500-2500 J/kg have supported brief strong pulse-type multicells capable of producing small hail and wind gusts to 50+ mph at times. Additionally, slow storm motions and abundant moisture have supported some locally heavy rainfall. NWP has not had a great handle on this weakly forced convection that has developed in/near a relative weakness embedded within a broad upper ridge. However the best guess is that the convection (largely off) Caprock will gradually fade by early this evening as the instability is consumed, while outflows from said convection may help spark additional development as they push westward onto the Caprock into largely untapped warm/unstable air. We may even see higher terrain convection originating in eastern New Mexico edge eastward into the western South Plains this evening. All said, we expect the best storm coverage to shift from the eastern zones currently to the central and western zones this evening. Some convection could then linger well into the night or redevelop early Sunday morning, similar to what has happened in the region the past few days. On Sunday we will see the mid-level weakness that has lingered nearby finally exit off to the east as heights/thicknesses gradually rise in advance of a storm system moving into California. This creates some doubt regarding storm chances/coverage by Sunday afternoon, but with a weak surface trough/dryline setting up near the TX/NM border and moderate instability and minimal inhibition progged near and east of the dryline by peak heating we could see isolated to scattered storm development. If storms do form, a few could again briefly become strong and produce locally heavy rain. Given the uncertainty regarding CI we have favored lower PoPs tomorrow, generally in the 20 to 30 percent range. It will be hot again tomorrow, and the western zones, where somewhat drier air may attempt to move in, could see readings make it into the middle 90s, while highs elsewhere will be primarily in the lower 90s. Lows tonight will be mild, in the 60s and lower 70s, with plenty of moisture and clouds in the region. .LONG TERM... Forecast toward hotter and drier is still on track for the upcoming week. Shortwave upper ridging Monday to be interrupted Tuesday by a shortwave trough ejecting across the central Plains. The ridge will then rebuild, initially over the Plains states midweek before retrograding to the Rockies and increasing in strength by 6 to 8 DM with the ridge approaching 600 DM by next weekend. Given presence of low level moisture, primarily off the caprock, precipitation chances will be non-zero through the week. Will maintain a slight chance mention Monday most of the area and Tuesday off the caprock where low level moisture will get shunted. From Wednesday through Saturday rain chances appear to be favored across the Rolling Plains furthest from the center of the upper high and where low level moisture is most likely to remain. However, given low confidence at this time will keep chances below the magical 15 percent. Highs near 100 likely by Wednesday and possibly continuing through Friday. A unique evolution to the upper pattern is progged late in the week with a cutoff upper low progged to retrograde from the Ohio Valley to the Ozarks. This could both drive a cold front through the forecast area Saturday and weaken the grip of the upper ridge slightly. Thus, a brief respite from the intense heat is possible. Will be interesting to see if the models hold onto this evolution as we proceed through the week. && .LUB Watches/Warnings/Advisories... None. && 23/07
