825 FXUS64 KMAF 210447 AFDMAF Area Forecast Discussion National Weather Service Midland/Odessa TX 1147 PM CDT Sun Jul 20 2025 ...New AVIATION... .KEY MESSAGES... Updated at 1145 PM CDT Sun Jul 20 2025 - Low to medium (10-50%) rain/storm chances are forecast from the western Permian Basin to the higher elevations west of the Pecos River this afternoon and evening. Best chances will lie over and near the Davis Mountains. - Near normal temperatures and low to high (10-70%) precipitation chances are ahead for many through much of the week. Greatest chances look to stay mainly west of the Pecos River each afternoon, especially near and over the Davis Mountains. && .SHORT TERM... (This afternoon through Monday night) Issued at 1239 PM CDT Sun Jul 20 2025 Radar is again showing isolated showers developing west of the Pecos River this afternoon. Today may be different from the past couple of days though as the latest hi-res models are showing greater coverage, also spreading farther east...possibly into the western Permian Basin. This is likely due to a combination of highs a couple of degrees hotter than yesterday allowing us to hit the convective temperature and a weakness in the upper level ridge increasing instability slightly. Temperatures tonight will hold in the mid to upper 70s as breezy south winds prevent good radiational cooling. An upper low currently over Southeast Texas will drift west overnight and into West Texas Monday. This feature will further destabilize the atmosphere and allow for a few more showers and storms to develop in the afternoon and early evening across the western two thirds of the CWA. An increase in cloud cover and more southeasterly low level winds could shave a couple of degrees off highs and bring them to near normal. && .LONG TERM... (Tuesday through Saturday) Issued at 1239 PM CDT Sun Jul 20 2025 In the long term, high pressure sits over the upper Mississippi River Valley early next week leaving West Texas and eastern New Mexico under southwesterly upper flow. Weak disturbances will move north out of Mexico and across the area Tuesday and Wednesday bringing at least a slight chance for rain for all but the far eastern Permian Basin. 500mb heights below 590dam suggest highs will be near or below normal continuing the relatively mild summer we have seen so far this year. By Thursday the ridge out east builds back into Texas increasing subsidence and thus highs creep back up into the upper 90s to near triple digits. Current models place the newly formed high center over the Texas Panhandle, perhaps far enough north that easterly flow remains over southwest Texas allowing temperatures to remain in the 90s. Should the high center locate even slightly farther south then the cooler easterly flow would be shut off and temperatures would likely reach into the lower 100s. Regardless, the high will be close enough that rain chances drop to near zero late in the week. Hennig && .AVIATION...
