.DISCUSSION...
Issued at 1130 PM MDT Sat Jul 25 2026

Persistent upper high over the Southern Rockies will remain fixed
over the region through at least the remainder of late July,
driving the weather pattern through the week ahead. GFS 500-mb
height anomalies suggest this high is 3-4 standard deviations
stronger than is typical for the middle of the North America
Monsoon. The pattern is not favorable for widespread rain, as any
storms that do form will be mostly driven by recycled moisture
and convective temperatures/terrain forcing producing meager
instability. Precipitable water values are just over an inch
through much of central New Mexico, with drier air across far west
Texas. Scattered thunderstorms are expected once again across the
southern NM high elevations and portions of the southwest New
Mexico lowlands. El Paso/Las Cruces should remain dry. Main threat
will be localized flash flooding, as storm motions remain very
slow if not stationary and capable of 1-2 inch/hour rainfall
rates.

Hot temperatures will also continue into the week ahead due to
this suffocating upper ridge. Highs will run 5-10 degrees above
normal for late July, which means lowland highs in the 100 to 105
degree range. Another Heat Advisory will need to be considered
for El Paso and Rio Grande Valley this week.

Minimal changes in the strength or orientation of the high for
Tuesday onward will make it difficult to pinpoint any appreciable
day-to- day changes with sensible weather elements. Overall
weather pattern will continue to be warmer-than-normal
temperatures and isolated rain chances focused mainly around the
southern NM high elevations. GFS/ECMWF both agree in a slight
retrograde of the upper high as we head into the first week of
August, which is still a poor weather pattern for rain chances.

.AVIATION...
(06Z TAFS)
Issued at 1054 PM MDT Sat Jul 25 2026

VFR conditions will prevail next 24 hours, with a few high
clouds. A widespread cu field is anticipated to develop during the
morning, w/afternoon convection possible KDMN/KTCS.

&&

.FIRE WEATHER...
Issued at 124 PM MDT Sat Jul 25 2026

No widespread critical fire weather conditions are forecast through
the next several days. Thunderstorms will favor the Gila wilderness
and Sacramento mountains, as well as the boot heel of NM with
more sparse storm activity only occasionally making it into lower
deserts of southwestern NM. Temperatures will be hot in lower
elevation deserts with minimum RH of 15 to 20% being common in the
afternoons. Wind concerns will be limited to thunderstorm
outflows on localized scales for brief time frames.
