.SHORT TERM...
(Today through Friday)
Issued at 133 AM CDT Thu Sep 24 2026
Our stagnant weather pattern remains in place tonight. Upper air
analysis this evening showed a 500mb high centered over southeast TX
and a large amplitude ridge stretching from there to the northern
plains. The flow over TX was anticyclonic and light. At the surface
the weak frontal boundary has pushed to the northeast into Central
and East TX. The low level flow across our CWA is from the southeast
keeping a warm (hot), moist airmass in place. The upper high will
remain in place through the short term period. The frontal boundary
may push back toward our CWA. There may be enough instability around
the front to generate isolated showers and thunderstorms this
afternoon and early evening again, but coverage looks to be less
than earlier in the week. Any convection should dissipate quickly
after sunset leading to a dry night. Friday it looks like the upper
high will suppress any convection keeping the entire are dry.
Temperatures through the period will be about the same as the last
few days.

.LONG TERM...
(Friday night through Wednesday)
Issued at 133 AM CDT Thu Sep 24 2026
The upper high will slowly shift to the south and west through the
end of the week. Strong subsidence from this feature will prevent
any convection Friday and Saturday. The airmass over South-Central
Texas remain about the same with low level flow from the east to
southeast. Temperatures will will also be stagnant through the
weekend. It will feel like an endless summer rather than the start
of fall. By Sunday the upper high will have shifted far enough that
isolated showers and thunderstorms will return during the afternoon
and early evening. This pattern will repeat Monday. Tuesday models
are showing the first real front of the season moving into TX. This
will bring chances for widespread rain Tuesday and Wednesday. The
front will move through our CWA Tuesday night and early Wednesday.
Northerly to northeasterly winds behind the front will bring cooler,
drier air. Highs Wednesday will be in the 80s in the Hill Country
and Southern Edwards Plateau and near 90 in the I-35 Corridor and
Coastal Plains.
