(This evening through Wednesday)
Issued at 115 PM CDT Tue Sep 23 2025
As of 3 PM the frontal boundary was draped just to the northwest
of the Big Country. Temperatures ahead of the boundary were in the
upper 90s to near 100 degrees. CAMs continue to show isolated to
scattered showers and thunderstorms developing along the front by
the late afternoon and evening. Cannot rule out a few storms
becoming strong to severe given moderate instability and modest
deep layer shear. Additional showers and thunderstorms are
expected to develop overnight as large scale ascent overspreads
the region. The severe threat will be lower compared to the
afternoon round, but marginally severe wind gusts will be
possible. Locally heavy rainfall and localized flash flooding will
also be possible with the heavier storms overnight. Scattered
showers and storms will linger into the afternoon hours, with the
highest PoPs shifting to the southern half of the area. Otherwise,
temperatures will be much cooler on Wednesday (70s and 80s) given
the extensive cloud cover in place and shower and storms.

.LONG TERM...
(Wednesday night through next Tuesday)
Issued at 113 PM CDT Tue Sep 23 2025
The cold front that brought rain chances during the day on Wednesday
will have moved into south central Texas by Wednesday evening. Some
residual lift is expected from the last of a mid-level impulse
passing through the region.  As a result, a few lingering showers
could still occur overnight from the Concho Valley southward, but
rainfall amounts should be fairly light.
For Thursday and Friday, quieter weather is in store as surface high
pressure will fill in behind the front. A cooler airmass, to the
tune of 15-18 deg C at 850mb, should overspread the region both
days.  This should translate to high temperatures in the mid to
upper 80s which is near normal for this time of year.  By late
Friday, the surface high will shift eastward and allow southerly
return flow to set up for this weekend and temperatures will return
to the low 90s for Saturday and Sunday. Models are in general
agreement of an upper-level low forming over southern California on
Saturday. However, models diverge significantly from run to run on
how to evolve this feature for early next week. The most recent runs
show this upper low becoming an open wave over the Desert Southwest
on Monday and having little to no effect on west central Texas.
Earlier runs show the low holding together and and perhaps bringing
some more rain chances to the region.  For now, the forecast for
Saturday through Monday was kept dry with temperatures near normal
as the region will be under an upper-level ridge.

(00Z TAFS)
Issued at 525 PM CDT Tue Sep 23 2025
Scattered showers and thunderstorms will move over KABI, with
isolated storms near KSJT this evening, before dissipating.
Strong gusty winds and brief IFR visibilities possible. Another
band of showers and thunderstorm with MVFR stratus will move in
late night along a cold front, beginning 10-12Z at KABI and KSJT,
then across the rest of the terminals after sunrise. Brief IFR
ceilings and visibilities possible in the morning. Scattered to
numerous showers across the terminals during the morning decrease
in coverage at KABI and KSJT in the early/mid afternoon, but
continue along the I-10 corridor including KSOA and KJCT. MVFR
rise to VFR late afternoon.
