667 FXUS64 KEPZ 101131 AFDEPZ Area Forecast Discussion National Weather Service El Paso TX/Santa Teresa NM 531 AM MDT Mon Aug 10 2026 ...New AVIATION, FIRE WEATHER... .KEY MESSAGES... Updated at 530 AM MDT Mon Aug 10 2026 - Drier conditions through Tuesday, with storm chances limited to western New Mexico and the high elevations. Rain chances increase again starting Wednesday as moisture returns, posing a risk of flash flooding. - Triple-digit heat continues for the Rio Grande Valley and Tularosa Basin. Slightly cooler conditions late this week. && .DISCUSSION... Issued at 1100 PM MDT Sun Aug 9 2026 UL high centered over the Four Corners continues to dominate our weather with dry, subsiding flow being advected into the CWA. This pattern has greatly limited storm coverage with only isolated storms and mainly over the Gila. More or less this pattern will hold steady through Tuesday though the 0Z HRRR is showing increased coverage in the lowlands Tuesday evening. I will discount it for now since the HRRR has had a notable wet bias for day 2 lately. By Wednesday, we are still expecting a pattern shift as the H500 high shifts over TX and OK, extending across the Gulf Coast. This will turn our flow from the south, tapping into subtropical moisture. Dewpoints will climb back above 50 with PW values climbing back above an inch (NBM mean generally ranges 1.1-1.3"). The increased moisture will bring shower and thunderstorm chances back into the picture, lasting through at least the end of the week. Additionally, both the GFS and ECMWF show a few systems riding up into area, which would enhance thunderstorm chances. Most notably, the GFS shows a substantial wave moving up from Mexico Wednesday night into Thursday and more or less stalling over NM. The ECMWF has a much weaker version of this feature and keeps it over AZ. Both models show another fairly substantial wave for next weekend but here too, both models differ in its evolution and track. && .AVIATION... (12Z TAFS) Issued at 530 AM MDT Mon Aug 10 2026 VMC through forecast period with clear skies and light SE winds. Afternoon conditions FEW-SCT100 with isolated TSRA across W NM. No TS impacts for local terminals today. Surface winds 150-180 at 5 to 10 knots. && .FIRE WEATHER... Issued at 530 AM MDT Mon Aug 10 2026 Low fire danger over the next several days due to wetness of local forests. Isolated (20-40%) thunderstorms each afternoon for Gila NF, but much of Lincoln NF will remain dry through Tuesday. Increasing moisture will allow for more widespread rain chances late this week. Storms will pose a risk of localized flash flooding and erratic outflow winds over mountains. Light SE winds today, shifting to the SW Tuesday through the rest of the week. 20-ft wind speeds 10 to 15 mph Wednesday/Thursday. Good ventilation rates each afternoon. Min RH 15-25%, with moisture increasing after Wednesday. && .PRELIMINARY POINT TEMPS/POPS...
