.UPDATE...
Issued at 630 AM CDT Thu Mar 26 2026

The short term was updated earlier this morning for a Wind
Advisory valid from 1 AM Friday through 7 PM Friday. Confidence is
high in widespread 30-40 mph winds with gusts to 55 mph, locally
higher. Potential for widespread gusts of 58+ mph remains too
marginal with the latest high res models. Also, we do expect a
round of blowing dust concentrated along the front overnight, but
this is expected to improve through the pre-dawn hours. No other
updates at this time.

.SHORT TERM...
(Tonight through Thursday)
Issued at 1108 PM CDT Wed Mar 25 2026

In the mid/upper-levels, a 590 dam subtropical ridge was centered
near ELP, with the 26/00Z RAOB launched from WFO EPZ having ascended
through the core of the mid-level, anticyclonic vortex. An elongated
jet streak stretches across the northern half of the U.S., with a
shortwave impulse, accompanied by a compact vorticity lobe that was
previously barotropic, digging into SoCal. As the subtropical ridge
shifts eastward over the TX Big Bend region Thursday, its amplitude
will become modulated as the shortwave impulse becomes absorbed into
the right-entrance region to the quasi-zonal jet streak over the
northern U.S. This will induce slightly negative geopotential height
falls over the CWA, leading to breezy and hot conditions for W TX,
with record high temperatures expected area-wide Thursday.

At the surface, a lee cyclone was located in the western TX PH near
the NM state line, with the dryline branching southward along the NM
state line and into the TX Big Bend. Winds have since backed towards
the south-southeast across the CWA, with the 50-degree isodrosotherm
currently advecting into the eastern Rolling Plains per recent WTM
data. Moisture return will continue throughout the nighttime hours,
with the dryline expected to stall near the edge of the Mescalero
Escarpment prior to sunrise Thursday. Overnight lows were raised a
few degrees due to the warm theta-e advection and as winds will
remain slightly breezy due to the maintenance of weak, leeward
pressure falls across the region.

Intense dry-bulbing is expected Thursday, with temperatures nearing
100 degrees for most locales as theta-e profiles become constant
with height. The prior record highs at CDS and LBB are 96 degrees
and 92 degrees, respectively; and both were set in 2020. Meanwhile,
veered surface winds will become breezy, with speeds between 20-30
mph expected as cyclogenesis of a 998 mb surface low occurs in far
southeastern CO beneath the ejecting shortwave impulse. The dryline
will propagate towards the I-27 corridor during the late-morning
hours and stall, and while it will bisect the CWA, critical fire
weather conditions are still expected across the Rolling Plains
despite RH minima near or slightly above 20 percent. Otherwise, RH
reductions into the middle single-digits are expected across the
Caprock by solar noon. A Red Flag Warning is in effect area-wide
between noon and 8 PM CDT Thursday.

.LONG TERM...
(Thursday night through next Wednesday)
Issued at 1108 PM CDT Wed Mar 25 2026

The dryline will begin translating westward after sunset Thursday,
with winds backing towards the south across the pre-frontal moist
sector while remaining westerly across far southwestern TX PH as the
surface low rotates southward. A polar cold front originating from a
fast-moving shortwave trough propagating over the 49th parallel is
expected to blast through the CWA prior to sunrise Friday. Winds
were raised slightly from the NBM, with at least advisory-level
winds expected area-wide Friday morning; and the gust factor was
also adjusted and capped at 50 kt. High winds may occur across some
portions of the CWA, but confidence is not high enough to warrant
the issuance of a watch with this prognostication. Blowing dust
should be kept at bay due to post-frontal moistening of the airmass,
with low stratus forecast to advect into the CWA Friday. Winds will
veer northeastward by mid-day Friday, with much cooler temperatures
forecast from the strong winds and thickening overcast. Highs were
lowered to align within the middle of the statistical guidance, but
additional downward trends to highs may be necessary in forthcoming
cycles. Fire weather concerns are low Friday, as the strong CAA and
thickening overcast yield RH minima at or above 30 percent.

The subtropical ridge will meander over S TX this weekend, although
the airmass will be slow to recover Saturday, with highs returning
to near seasonal norms. Highs will rebound into the upper 80s by
Sunday into early next week, with the subtropical ridge forecast to
flatten by Monday as broad trough emerges over the Rocky Mountains
and into the southern Great Plains. Low chances for thunderstorms
are forecast to return late Monday as a Pacific cold front nears the
region. The forecast remains dry otherwise through the remainder of
the extended period.

.AVIATION...
(12Z TAFS)
Issued at 630 AM CDT Thu Mar 26 2026

VFR S-SW winds jumping to 15-25 knots at all sites with higher
gusts. After scaling lower by sunset, strong N winds sweep in
after midnight with a strong cold front. A brief window for BLDU
with lower visbys is likely during FROPA before improving through
daybreak. LBB will likely need an Airport Weather Warning in
later TAF cycles.

.FIRE WEATHER...
Issued at 1108 PM CDT Wed Mar 25 2026

Southeasterly winds will remain slightly breezy through the predawn
hours Thursday. RH recovery this morning is expected to recover to
above 70 percent, as the dryline will remain parked near and west of
the NM state line. Following sunrise, winds will begin to veer
towards the southwest, with the dryline moving eastward towards the
I-27 corridor where it will eventually stall. Winds will become
breezy by the late morning hours in response to a strengthening
surface low in southeastern CO, with southwesterly winds increasing
to 20-30 mph across the Caprock while remaining south-southwesterly
in the Rolling Plains during the afternoon hours. The lowest RH
reductions will occur on the Caprock, with RH minima in the middle
single-digits. RH is expected to fall near 20 percent in the Rolling
Plains, but with near-triple-digit temperatures and high fuel
loading, conditions will be more than favorable for the growth and
spread of wildfires despite the more-marginal RH relative to areas
farther west. A Red Flag Warning is in effect between noon and 8 PM
CDT today. A strong cold front will then blast through W TX during
the early morning hours Friday, with advisory-level winds expected,
in addition to much cooler temperatures Friday afternoon.
