Updated at 532 AM MDT Sat Aug 22 2026 - Isolated showers and thunderstorms over the higher terrain on Saturday. Thunderstorm chances will diminish 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 1100 PM MDT Fri Aug 21 2026 High pressure aloft centered over the Southern Rockies will be the primary driver of our weather pattern over the next several days. Thunderstorm development through the weekend will be driven by recycled moisture under this upper high, with less and less coverage each day as drier air moves in. The main headline will be above normal temperatures, which looks to stay in place through the rest of August. Lowland highs consistently in the 98-102 degree range will run 8-10 degrees above normal for late August and near daily records. Currently no daily record for El Paso in the forecast, but were only 1-2 degrees off most days going forward. Earlier this evening we saw isolated showers and thunderstorms across southwest New Mexico. Sounding PWs were 1.0-1.1, with barely enough instability (400-800 J/kg), and a mix of convective temperature/terrain forcing. Storms were quite weak, with 10-20% coverage over the lowlands and more notable winners being the southwestern rim of the Sacramento Mountain and southern Black Range. For Saturday, expect more of this weak convective activity, only another tick lower in coverage. Lowland chances fall below 5%, especially for the I-10 corridor. Any storms that do form will favor the high elevations, popping around noon and diminishing prior to sunset. Best chances will focus over Grant County. Storms will be capable of brief downpours and gusty winds up to 45 mph. Sunday will be even drier, with very spotty mountain showers and almost no action for lowland zones. Upper high drifts east directly over the Southern High Plains into early next week, leading to a near-total shut off of moisture flow and the end of storm chances area wide. Precipitable water values 0.8-1.0 will fall below the climate normals and strong (and very warm) subsident flow within the 400-600mb layer aloft will hinder updraft development. The primary monsoonal plume will be pushed west across Arizona and the Colorado River valley. This pattern looks to remain in place through next week, leading to an extended period of late-August dryness and heat. && .AVIATION... (12Z TAFS) Issued at 532 AM MDT Sat Aug 22 2026 VFR conditions should prevail through the period. Isolated showers persist N of KLRU and KDMN this morning, drifting westward. The activity should fizzle out after sunrise, followed by isolated TS over high terrain this afternoon. KTCS is most likely among terminals to see a storm in the area, but only about 10%. Winds remain AOB 8kts. && .FIRE WEATHER... Issued at 532 AM MDT Sat Aug 22 2026 Fire weather concerns will be low through next week. Isolated showers and storms develop over area mountains this afternoon with less coverage and intensity than yesterday. Gusty winds to 40 mph and brief downpours are the main threats. Prevailing winds will be light from the east-southeast today. Dry conditions are expected for the lowlands with very warm temperatures. The upper high moves more overhead next week, largely shutting off rain/storm chances. Only slight storm chances remain over high terrain as modest SE flow persists. Temperatures stay above normal, approaching record highs. ERC`s are forecast to climb towards the 75th %-ile. Min RHs will be 10-15% in the lowlands; 20-35% in the mtns today, then 15-30%. Vent rates will be fair to good in mtns today, good to excellent in lowlands; then good to very good. && .PRELIMINARY POINT TEMPS/POPS...
