.SHORT TERM...
(Today through Sunday)
Issued at 1200 AM CDT Sat Sep 26 2026

Another day with the 500mb high centered over southeast TX and
a large amplitude ridge stretching from there to the northern
plains. At the surface the weak frontal boundary that has been in
the region is across our eastern counties. This boundary is really
not having any affect on the weather. The low level flow across
our CWA is from the southeast keeping a warm (hot), moist airmass
in place. The upper high will drift to the southwest through the
short term period. Today it will suppress any convection keeping
the entire area dry. Sunday the upper high may be far enough south
and west to allow a few showers or thunderstorms to develop
during the afternoon. If any storms do form it will most likely be
over the Hill Country. Temperatures through the period will be
about the same as the last few days.

.LONG TERM...
(Sunday night through Friday)
Issued at 1200 AM CDT Sat Sep 26 2026

The upper high will continue to shift to the south and west Monday.
The airmass over South-Central Texas will remain about the same with
low level flow from the east to southeast. Temperatures will be
stagnant through the beginning of next week. It will continue to
feel like an endless summer rather than the start of fall. Models
are still showing the first real Pacific cold front of the season
moving into TX, but the timing is not consistent. Now it`s looking
later in the week. Despite this change there are still chances for
widespread rain starting Tuesday and extending into Friday. They are
also showing signs of possible heavy area at times during this
period. Northerly to northeasterly winds will bring cooler, drier
air. High temperatures for the second half of the week may be below
90 for most of the CWA, but low temperatures have trended a little
warmer and mostly above 70.

.AVIATION...
(12Z TAFS)
Issued at 554 AM CDT Sat Sep 26 2026

Light SE onshore low level winds will bring just enough moisture
to allow for some SCT V BKN MVFR CIGs through around 15Z. VFR
skies will otherwise prevail with mainly some areas of
cirrostratus moving over the area. More of the same is expected
tonight as the pattern of ridging aloft and light onshore surface
winds continues. MOS guidances held of with the lower CIGs so we
decided to do so as well.
