.SHORT TERM...
(This evening through Sunday)
Issued at 128 PM CDT Sat Sep 19 2026

Another hot and breezy day across west central Texas. A few
isolated showers and storms are possible this afternoon and
evening across our far western counties, but most activity will
remain to our west across the higher terrain of west Texas. A
little better chance of isolated to scattered showers and
thunderstorms across the area on Sunday. The upper ridge will
weaken enough to allow a weak shortwave to move overhead. Have
kept PoPs mostly in the 20-50% range in the afternoon and evening.
The strongest storms will be capable of producing gusty downburst
winds along locally heavy rainfall.

&&

.LONG TERM...
(Monday through Saturday)
Issued at 1205 AM CDT Sun Sep 20 2026

A weakened/suppressed ridge aloft will be over the southern part of
Texas and the adjacent part of northeastern Mexico Monday into
Tuesday. Models hint at a possibility of a weak disturbance or two
moving around its northern periphery Monday and Tuesday. Trailing
portion of a cold front is forecast to move south into the Big
Country on Monday, and into the central part of our area Monday
night before stalling. With a combination of weak upper support,
surface frontal boundary and possible leftover outflow boundaries
from previous convection, much of our area has low to medium chances
(20-50%) for showers and thunderstorms Monday through Tuesday and
into Tuesday night. A few strong storms will be possible in the
afternoon/early evening hours with localized downburst winds and
frequent lightning the primary hazards. The airmass will be moist
and with precipitable water values 1.4 to 1.8 inches, locally heavy
rainfall will be possible. Temperatures Monday and Tuesday will be a
little cooler but still above normal for September 21-22. For the
most part expect highs to be in the lower to mid 90s Monday and
upper 80s to mid 90s Tuesday. Lows will be in the upper 60s and
lower 70s. Will be monitoring subsequent model trends for the
possibility of highs to be a little cooler than currently forecast
in the Big Country behind the front.

The upper high is forecast to strengthen a little and be centered
over the Texas coast Wednesday and Thursday into Friday. By
Saturday, the high is progged to be centered over Deep South Texas.
While an isolated shower/thunderstorm cannot be ruled out mainly in
our northwest and northern counties, the higher rain chances are
expected to be in West Texas toward the Red River with mostly dry
conditions for our area. Highs are expected to be several degrees
above normal in the lower to mid 90s.

.AVIATION...
(06Z TAFS)
Issued at 1235 AM CDT Sun Sep 20 2026

Predominantly a VFR forecast the next 24 hours. Winds will be
south to southeast between 5 and 10 knots, with a few gusts over
15 knots at KABI and KSJT tomorrow afternoon. The chance for
showers and thunderstorms will increase across the area this
afternoon into the evening hours. Will include PROB30 groups
at all terminals this forecast cycle to account for convective
potential. Expect brief reductions to ceilings/visibilities
associated with any convection.
