The episode as NWS MAF wrote it up.
A weakened upper ridge was over the region. There was a cold front/outflow boundary across the area along with a couple of other outflow boundaries which provided a focus for thunderstorm development. Southeast winds resulted in upslope flow along the higher terrain in West Texas and southeast New Mexico. These southeast winds also resulted in moisture being transported into the area, and daytime heating aiding in lift which created an unstable atmosphere. There was also an area of intense low-level winds, known as a low-level jet, which helped storms continue into the overnight hours. The storms produced severe wind gusts across West Texas and southeast New Mexico.

NWS Midland/Odessa, TX wrote its last area forecast discussion before the first event at Jul 1, 5:16 PM CST, 19 minutes earlier.
Area Forecast Discussion National Weather Service Midland/Odessa TX 616 PM CDT Sat Jul 1 2017 .DISCUSSION... See aviation discussion below. && .AVIATION... VFR conditions are expected at the southeast New Mexico and west Texas terminals the next 24 hours. Will be watching the potential for thunderstorms developing and tracking off the New Mexico mountains this evening and overnight into the southeast New Mexico Plains, including KCNM and KHOB. Will leave out mention of storms for now at these terminals but will continue to monitor. 12 && .PREV DISCUSSION... /issued 220 PM CDT Sat Jul 1 2017/ DISCUSSION... A cold front/outflow boundary has moved south into the area behind convection which moved southeastward into central Texas earlier today. This boundary, along with a couple of other outflow boundaries, will likely provide a low level focus for thunderstorm development this afternoon/evening, and perhaps a focus for a MCS tonight. Temperatures will not be as hot today as Friday, but dewpoints are higher due to easterly low level flow, so instability will not be lacking to fuel thunderstorm development. In addition, the easterly upslope flow into the higher terrain has aided additional scattered thunderstorm development, with more expected through max heating. SBCape will be 1500-2500 J/Kg over all but the northeastern CWA, and on the western side of the higher terrain in Jeff Davis and Presidio counties, while mid level lapse rates will be rather steep around 8 C/Km. Strong winds will be the primary threat from thunderstorms this afternoon and tonight, but there may be enough 0 to 6Km shear for a few organized storms and large hail this afternoon. Thunderstorms could band together over the higher terrain of southeastern New Mexico and west Texas, and aided by a progged 30-40kt h85 LLJ, form an eastbound MCS overnight. Models have been remiss on how long previous MCSs have lasted overnight so will have at least a slight chance of thunderstorms all the way to the eastern and southeasternmost counties in the CWA. Strong winds could occur along portions of any linear MCS overnight, and to a lesser extent, heavy rainfall. A weakened upper ridge over the region today will gradually retrograde and reform over the Four Corners region by mid next week where it is progged to stay through next weekend. Temperatures will stay hot/above normal, but not as hot as what we just had the last couple of days of June. Since the upper ridge will not be centered over us, and low level moisture will be present through the extended forecast, we could see similar occurrences with thunderstorms as Friday and Friday night, and what is expected through tonight. Shear will be on the weak side due to the proximity of the upper ridge, but there may be a little stronger shear a couple of the upcoming days, or enough instability, to be concerned about strong thunderstorm wind gusts. All the low level moisture that looks to be available through the extended, and the mainly weak flow aloft could result in episodes of heavy rainfall too. It is difficult to project where specific meteorological features will be in 12-24 hours during the summer, much less 5-6 days out, but between the heat and expected moisture availability, will keep a chance of thunderstorms in most locations through the extended. && .PRELIMINARY POINT TEMPS/POPS...
