.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.
