.SHORT TERM...
(Tonight through Sunday night)
Issued at 1204 PM CST Sat Dec 27 2025

With the past week's strong ridge now shifting east of the local
area, the eastern fringes of an upper-trough and its flanking
subtropical jet are beginning to push into the Central US. The
primary zones of ascent remain well to our north, so we don't expect
much considerable change in the weather tonight or during the
afternoon Sunday. Tonight's low-level jet does strengthen to about
20-30 kt over our area in response, so a moderate breeze should
persist especially at higher elevations and coverage of fog will
likely be reduced compared to previous mornings. The intensified LLJ
will also stream more moisture into the area for Sunday, leading to
more cloud cover sticking around during the daytime. That may shave
off a few degrees for highs, though warm southwest flow should
continue to support another warm day with highs in the upper 70s to
low 80s.

Our week of unseasonably warm and muggy weather should come to an
abrupt end Sunday night with the arrival of a strong polar cold
front. With the frontal passage now in range of the higher
resolution models, the timing has trended slightly sooner, and the
front could arrive at the northern Hill Country as early as about 6
PM CST tomorrow evening. The front should move speedily through the
area thanks to its robust density current speed and supportive
northerly flow at 850mb, likely reaching US-90/I-10 by 10 PM CST and
exiting the Coastal Plains and Rio Grande Plains by about midnight
Monday. Some spots could see a quick 10-degree drop within the first
hour of the frontal passage. Model soundings have remained
consistent in showing a decently mixed boundary layer up to about
2000 ft AGL, which could transfer strong gusts to the surface. The
HREF ensemble members show widespread north winds of 15-25 mph
across the vast majority of South-Central Texas Sunday evening into
the overnight. Mean boundary layer winds of 30-35 kt are depicted in
the latest RAP13 and NAM12 models, which supports the 40-45 mph
gusts exhibited in the REFS ensemble. These winds should develop
quickly Sunday night and continue into Monday morning. It'll be a
good idea to secure loose outdoor objects and holiday decorations. A
thin line of showers is possible along the front mainly along and
east of I-35 Sunday evening. However, the dry and windy post-frontal
air, unsupportive thermodynamics aloft, and speed of the front will
curtail rain amounts to mostly a few hundredths of an inch of
rain.

&&

.LONG TERM...
(Monday through next Saturday)
Issued at 1204 PM CST Sat Dec 27 2025

Monday morning will be quite the drastic change from previous muggy
mornings. The much colder air arriving behind the overnight cold
front is expected to push lows into the 30s and 40s across South-
Central Texas. Coupled with a 20 mph wind and gusts of at least 30
mph for many locations, wind chills may be in the upper 20s and low
30s for portions of the southern Edwards Plateau and Hill Country.
Strong cold air advection during the day and residual post-frontal
stratus will likely keep temperatures low throughout Monday with
highs in the 40s and 50s. Much drier post-frontal air and gusty
winds will likely produce at least elevated fire weather conditions
across the area Monday afternoon. Winds should be at their strongest
Monday morning but gradually taper during the day to a more ordinary
breeze by around sunset.

The cold post-frontal airmass sticks around until about midweek.
Lows Tuesday and Wednesday morning are forecast to be in the 30s to
low 40s across South-Central Texas, with light morning freezes
possible mainly north of I-10. A gradual warming trend should return
midweek heading into 2026 as mid-level ridging passes overhead. New
Year's Eve looks seasonably cool and New Year's Day a touch milder
with highs in the 60s to low 70s. Aside from Sunday/Monday's front,
rain is kept out of the forecast for next week. That said, the
subtropical jet stream may be in flux over the eastern Pacific and
southwestern US during the week, which could send a weak disturbance
or two worth monitoring for low rain chances middle to late next
week.

.AVIATION...
(00Z TAFS)
Issued at 604 PM CST Sat Dec 27 2025

VFR conditions through the evening hours across South-Central
Texas. Stratus will gradually re-develop 04Z-08Z across the
Coastal Plains, I-35 corridor, and Hill Country. The stratus is
expected to spread westward into the Rio Grande 09Z-13Z. We
continue to forecast closer to a persistence ceiling/visibility
forecast from recent nights at AUS and SAT given the elevated
winds and mixing overnight. We expect a mix of IFR and MVFR
ceilings along the I-35 corridor, including SAT and AUS,
developing overnight through morning. LIFR ceilings are more
likely to occur between HDO-DRT. Conditions are forecast to
gradually improve 15Z-20Z Sunday.

A strong cold front is forecast to move through the region
between 00Z-06Z Monday, bringing north winds with gusts initially
around 25-30 KT at AUS and SAT, increasing 06Z-12Z Monday to
30-35 KT.
