The episode as NWS MAF wrote it up.
Moisture and instability were fairly high with weak upper level winds. Thunderstorm outflow boundaries were across the area which provided a focus for new storm development. These conditions resulted in a storm that produced flash flooding in West Texas.
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 Midland/Odessa, TX wrote its last area forecast discussion before the first event at Jul 23, 1:38 PM CST, 2 hours 20 minutes earlier.
Area Forecast Discussion National Weather Service Midland/Odessa TX 238 PM CDT Thu Jul 23 2020 .DISCUSSION... Similar to the last couple of days, isolated to scattered convection has developed near the mountains and portions of the Permian Basin this afternoon. Expect this activity to continue through this evening as upslope flow persists along the higher terrain and additional storms develop along lingering and new outflow boundaries across the plains. Individual storms will be short lived with gusty winds being the main threat as cells develop and quickly decay. Friday, upper ridging will strengthen over the south central Plains, shunting better mid level moisture westward and suppressing thunderstorm development across the eastern half of the forecast area. As a result, we'll see best chances for rain across southeastern New Mexico and south through the mountain regions Friday and Saturday afternoons. Near normal temperatures with highs generally in the mid 90s can be expected during this time. Our attention then turns to Sunday as the remnants of a tropical system (currently Tropical Depression 8 located in the central Gulf of Mexico) moves just south of the Big Bend region. As this occurs, the aforementioned upper ridge will expand westward a bit, keeping best rain chances south of the forecast area. At this time, areas along and south of Interstate 10 may receive a quarter to half an inch of rainfall through Monday. Will be a few degrees cooler across the forecast area during this time with increased in cloud cover expected. The upper ridge will retrograde westward through the beginning of the work week and highest rain chances look to remain across the mountain areas and south over the Big Bend region. && .PRELIMINARY POINT TEMPS/POPS...
