The episode as NWS MAF wrote it up.
An upper trough moved over the Central Plains, and there were a couple of surface boundaries across the region. Afternoon heating, along with clearing skies, helped to destabilize the atmosphere. These conditions, along with very rich moisture, allowed for heavy rain and flash flooding to develop across the Permian Basin.

NWS Midland/Odessa, TX wrote its last area forecast discussion before the first event at Aug 1, 5:27 PM CST, 1 hour 47 minutes earlier.
Area Forecast Discussion National Weather Service Midland/Odessa TX 627 PM CDT Tue Aug 1 2017 .DISCUSSION... See 00Z aviation discussion below. && .AVIATION... Scattered light to heavy SHRA is currently seen on radar though lightning strikes have been few, therefore will leave TS out of the TAFs for now and keep SHRA as the prevailing weather for the next few hours. Rain ends by 06Z with MVFR CIGs developing at a few TAF locations. For now have brought the low clouds into MAF/FST but it could extend east to INK/HOB as well. VFR again by 18Z. Hennig && .PREV DISCUSSION... /issued 240 PM CDT Tue Aug 1 2017/ DISCUSSION... Not much left of the overnight/morning activity by this afternoon however cloud cover remains over most areas, holding temperatures in the 80s. What a welcomed break from the heat! Currently have some isolated to scattered convection popping up across a few areas where clearing skies and afternoon heating have helped to destabilize the atmosphere invof of a couple of surface boundaries draped across the region. Not confident we will see widespread convection this evening however a few hi-res models were generating quite a bit of precip...so will continue chance PoPs through tonight, especially across the south. PWATs remain near 1.5 inches so heavy rainfall leading to areas of flooding continues to be the main concern with any storm. Wednesday will be a few degrees warmer as cloud clear a bit. Thunderstorm chances look to remain across the southern areas where a surface boundary may reside invof mid level theta-e ridge. The warming trend continues Thursday but this will be short-lived as a trough moves into the Great Lakes region Thursday night, sending a cold front south into the area Friday. The front looks to be fairly weak by the time it gets this far south with a weak wind shift to the east but will knock temperatures down a few degrees. Rain chances look fairly low as this front approaches, best chances across the northern zones attm. South winds return Saturday with high temps warming back into the low/mid 90s for the weekend. May see an upper shortwave or two move across the region this weekend, keeping decent rain chances in the forecast through this weekend and heading into the next work week. && .PRELIMINARY POINT TEMPS/POPS...
