Updated at 1229 PM MDT Fri Aug 21 2026 - Showers and thunderstorms over the higher terrain today will run into a less favorable environment as they approach the desert lowlands. Very spotty thunderstorms will try to work into the lower elevations, with gusty outflow winds. - Thunderstorm chances will diminish rapidly this weekend as upper level high pressure builds closer to the area. - Above normal temperatures across southern New Mexico and far west Texas through the week ahead. Lowland highs will be in the upper 90s to lower 100s, which will approach daily records. && .DISCUSSION... Issued at 1229 PM MDT Fri Aug 21 2026 The subtropical ridge is parked over Colorado today, with east to northeast flow steering some limited, recycled moisture around. We are already seeing some convection firing up in the higher terrain of the Gila Region and Sacramento Mountains. Much like yesterday, these storms will drift into the lowlands, but struggle as they move into a more hostile environment. The 18Z sounding tries to look impressive, with 1500 J/Kg and limited CIN based on the forecast surface temperature, but this doesn`t take into account mixing out of the dewpoints, which are on their way to the lower-40s for the lowlands. Drier and warmer air aloft will work into the area through the weekend, heavily suppressing convection chances, even in the higher terrain. Temperatures will remain in the 100 to 103 range in the lowlands through the weekend, and will attempt to crawl a little higher than that early next week as the upper ridge settles over southern New Mexico. Very spotty convection may return to the higher terrain around that time. && .AVIATION... (18Z TAFS) Issued at 1229 PM MDT Fri Aug 21 2026 Mostly VFR conditions through the period, but isolated thunderstorms will attempt to drift into the lowlands later this afternoon and evening, struggling as they go. Brief thunder and gusty outflow winds will be most likely at TCS and LRU. && .FIRE WEATHER... Issued at 1229 PM MDT Fri Aug 21 2026 Showers and thunderstorms over the higher terrain again today will run into a less favorable environment as they drift towards the lowlands. Above normal temperatures will continue through the weekend, with an overall drying trend from Saturday as the upper ridge squashes convection chances area-wide. With the hot/dry spell, ERCs are forecast to climb towards the 75th percentile next week. Min RHs will range from 12-20% for the lowlands through Sat, then 10-15%; 20-35% for mtns through Sat, then 15-25%. Vent rates will be good to very good. && .PRELIMINARY POINT TEMPS/POPS...
