.KEY MESSAGES...
Updated at 1221 PM CDT Sat Sep 26 2026

- Warmer and drier conditions return this weekend, with the
  exception of areas across the Davis Mountains extending into the
  Big Bend.

- Another storm system is forecast to impact the region by early
  to mid-week. Heavy rainfall is expected with this system, which
  will elevate the risk for flash flooding.

.SHORT TERM...
(Today through Sunday afternoon)
Issued at 312 AM CDT Sat Sep 26 2026

Radar imagery as of 2 AM CDT show thunderstorms dissipating across
portions of southeast New Mexico. For today, weak upper-level
ridging begins to build back into the region, supplying warmer and
drier conditions for most. High temperatures are expected to reach
back into the upper 80s and low 90s for most locations. Weak
disturbances aloft combined with surface troughing and upslope flow
induces isolated to widely scattered storm development during the
afternoon/evening across the Davis Mountains, Lower Trans Pecos, and
Big Bend region. Remnant outflow boundaries from the TX Panhandle
supply a low chance (10-20%) for isolated storms across the
Permian Basin today. High resolution forecast soundings continue
to depict inverted-V profiles, high DCAPE ( > 1000 J/kg) values,
high PWATs (75th to 90th climatological percentile), "skinny" CAPE
profiles, and sufficient deep-layer shear signaling a heavy
rainfall and gusty wind threat associated with the strongest
storms.

Tonight, upper-level ridging continues to build into the region.
Lows are forecast to span from the 60s to low 70s for most
locations. Drier and warmer conditions persist on Sunday from the
influence of the aforementioned ridge. Disturbances in the flow
aloft will provide low rain/storm chances (10-30%) for areas
across the Davis Mountains into the Big Bend region during the
afternoon. A more active and cooler weather pattern takes shape
next week. See the long-term discussion for more details!

.LONG TERM...
(Sunday night through Friday)
Issued at 312 AM CDT Sat Sep 26 2026

Another upper-level system approaches the region beginning on
Monday, providing an active weather pattern through at least the
middle part of next week. Rain chances start to increase for the
western half of the region as the storm system approaches. Long-
range guidance has what is going to be the remnants of Hurricane
Polo being absorbed into the aforementioned storm system. This is
going to supply vast amounts of upper-level and surface moisture
transport, resulting in areawide rain chances by Monday night
lasting through Wednesday. Guidance has indicated Tuesday will be
the "rainiest" day per the positioning of both systems. Ensemble
guidance also suggests PWATs reaching near and even exceeding
daily maximum climatological values throughout Tuesday. Therefore,
the threat of heavy rainfall leading to flash flooding returns.
There remains uncertainty regarding the exact setup and specific
impacts with this upcoming system. We will continue to monitor
trends closely. Besides the rain, a cold front is forecast to move
through the region sometime on Wednesday/Wednesday night bringing
cooler temperatures in the upper 70s to mid 80s. Drier conditions
and similar temperatures (low to upper 80s) are expected behind
the front Thursday and Friday.

(18Z TAFS)
Issued at 1221 PM CDT Sat Sep 26 2026

VFR conditions prevail through the period with light southwesterly
to westerly winds. Isolated to scattered showers and thunderstorms
develop this afternoon around the Stockton Plateau, so have included
a PROB30 for -TSRA at FST. While isolated to widely scattered
showers and storms are also expected to develop in the Permian
Basin, chances were too low to include a PROB30 for MAF at this
time. TEMPOs will be added as necessary.
