The local office's own words before this special weather statement went out, 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 this special weather statement went out at Jul 22, 2:33 PM CDT, 2 hours 19 minutes earlier.
Area forecast discussion, Jul 22, 2:33 PM CDT, 2 hours 19 minutes before
Area Forecast Discussion National Weather Service Midland/Odessa TX 233 PM CDT Sat Jul 22 2017 .DISCUSSION... Current radar is showing diurnally driven convection increasing across the area this afternoon. The mountains are helping storms develop west of the Pecos River, but farther north a weak upper low over east-central New Mexico and an associated shear axis over the western Permian Basin is drawing moisture north and aiding storm development in the lower elevations. There is very weak steering flow near the shear axis causing slow storm movement which will be conducive to localized flooding, especially in urban areas. This activity will diminish after sunset with more expected tomorrow and Monday as the upper air pattern persists for a while longer. Models then show an upper high building south into the CWA by the middle of next week, increasing subsidence and sending highs back into the triple digits for many locations. Back in June, such high temperatures caused strong instability and severe storms to develop, however upper heights were lower then weakening the cap. Models are now showing 500mb heights of 594-596dam beginning Tuesday which should do a better job of inhibiting convection so forecast PoPs will diminish toward the end of the forecast.
