The episode as NWS MAF wrote it up.
There was an upper trough that extended from West Texas to the Central Plains. Very rich moisture was across West Texas and southeast New Mexico. These conditions resulted in thunderstorms with damaging winds across the Permian Basin.

NWS Midland/Odessa, TX wrote its last area forecast discussion before the first event at Aug 25, 5:17 PM CST, 3 minutes earlier.
Area Forecast Discussion National Weather Service Midland/Odessa TX 617 PM CDT Fri Aug 25 2017 .AVIATION... 00Z TAF issuance. Currently have scattered thunderstorms across the region this evening. May continue to see storms into the overnight hours but maybe more isolated. For now, will continue TEMPO TS at most terminals through 02Z and amend later if needed. Storms have been producing very heavy rain and may result in brief periods of low vis. Similar to this morning, could see low clouds affect a few terminals early Saturday so will continue to advertise MVFR at all but CNM and INK. VFR conditions will return by mid morning Saturday. && .PREV DISCUSSION... /issued 225 PM CDT Fri Aug 25 2017/ DISCUSSION... Radar is showing scattered showers and storms developing across the area this afternoon. The motion will be slow and erratic, mainly outflow dependent as opposed to moving with the environmental flow which is very weak. This means some areas may get in excess of an inch or two of rain while others nearby get very little if any. This will create some potential for flash flooding but it will be very localized. This activity is due to an upper level trough that extends from West Texas to the Central Plains. The trough will weaken and move east over the next 24 hours and high pressure over the western U.S. will extend east bringing drier air and an end to our rain chances next week. High pressure and dry conditions do not usually mean cool air for our CWA, but that is what MEX guidance is indicating. The reason the MEX is so cool is the GFS is advecting cooler air from Hurricane Harvey west due to easterly and northeasterly surface winds around it's circulation. While there is no doubt this will occur, it is hard to imagine we will stay in the 80s without a cold front or appreciable rain so this forecast is generally several degrees higher than MAV/MET/MEX guidance and closer to the ECE guidance.
