KEY MESSAGES

Updated at 230 PM MDT Thu Jul 23 2026

- Monsoon moisture diminishing today and Friday, with isolated storms mainly over higher mountains.

- High pressure settling over the region will bring the heat. Temperatures will peak near 105 around El Paso, the Mesilla Valley, and other lower elevation areas on Friday. Triple digits look to continue through the weekend and into early next week.

- Slightly better storm chances return Saturday and Sunday, but still mainly over the mountains and out west.

DISCUSSION

Issued at 230 PM MDT Thu Jul 23 2026

The subtropical ridge is centered over north Texas, and stretches west-east across the continent from southern California, across southern New Mexico, and into northern Florida. As a result, we've seen a significant jump in temperatures both at the surface and aloft, and suppressed convective activity.

Temperatures look to top out around 101 or 102 at ELP today, and should reach 105 on Friday (tomorrow). Heat Advisories have been raised for El Paso and Las Cruces, and most areas where elevations are below 4000 feet.

The upper ridge will recenter itself near the NM/AZ border tomorrow, while an inverted trough associated with the remnants of Tropical Storm Bertha move into northeastern Mexico. Tomorrow looks like mostly a down day convection wise, but the GFS does show a little pocket of cooler air at 500 mb trying to rotate around the edge of the ridge. Something to watch, but still think we'll see only isolated convection in the higher mountains.

While the inverted trough still looks to stay too far south to impact our weather much, some recycled upper level moisture will work into the area Saturday. Mid level temperatures still look atrociously warm, -2 to -3C at 500 mb, but increasing low level southeasterly flow will boost lower level moisture. Models show increasing precip chances Saturday afternoon and evening, especially across the Gila, despite the warmer air aloft. While there is no obvious disturbance to work with, the GFS does show a weak PV anomaly in the 335-345K layer drifting through.

For Sunday, a very weak inverted trough (only noticeable in 200 mb streamlines) will move across central Chihuahua, with a little 50 knot ESE "jet streak" moving over southern NM. Moisture looks limited mostly to areas west of the Rio Grande (and more so west of the the Continental Divide).

Moisture will try to crawl back east early next week, but we will continue to battle drier air coming in aloft from central Texas. All in all, sort of a sink-or-swim, sputtering start to the monsoon.

AVIATION

(18Z TAFS) Issued at 230 PM MDT Thu Jul 23 2026

VFR conditions and light winds expected through the period with convection chances near nil.

FIRE WEATHER

Issued at 230 PM MDT Thu Jul 23 2026

Upper level ridging will expand over southern New Mexico on Friday, continuing to boost temperatures into the 100s over the lowlands. Thunderstorm chances will remain suppressed and mostly focused over area mountains. A slight uptick in thunderstorm activity is expected this weekend with a focus for storms still over the area mountains and western locations near the AZ border. Min RHs will stay generally near critical with some critical locations across the lowlands each day through midweek with the area mountains seeing RHs of 25-45%. 20 foot winds stay light each afternoon at 5-10 mph.
