KEY MESSAGES

Updated at 530 PM MDT Fri Aug 21 2026

- Isolated showers and thunderstorms over the higher terrain on Saturday. 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 1200 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

(00Z TAFS) Issued at 530 PM MDT Fri Aug 21 2026

Diminishing VCTS across SW NM next few hours, with VCSH around KTCS/KDMN through 02Z. Skies SCT-BKN150 overnight with surface winds 060-100 at 5 to 10 knots. Isolated TS across SW NM between 19-23Z tomorrow, likely not affecting TAF sites. No mention of TS in this forecast due to low confidence in direct impacts. Prevailing surface winds 100-140 at 8 to 12 knots tomorrow.

FIRE WEATHER

Issued at 1200 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.
