.SHORT TERM...
(Today through Saturday)
Issued at 124 AM CDT Fri Oct 2 2026

A rather tricky forecast for the early morning hours of Friday as hi-
res guidance is in disagreement on whether or not storms will
redevelop along the I-35 Corridor/within the Hill Country. The RRFS
and HRRR have been aggressive in forming additional convection
between 04-06Z and continuing through the morning hours, however,
the WoFS and other models have been less enthusiastic about
redevelopment. As it stands right now, convection in the CRP CWA may
hold the keys to whether or not additional storms develop behind the
convection to our south and east as southerly flow at 850mb is still
noted per the latest mesoanalysis. If convection along the coast
weakens a bit, that may open the door for redevelopment further
inland.

The remainder of the day Friday brings some uncertainties, but with
500mb troughing still in play and plenty of anomalously high
moisture to work with, scattered showers and storms will likely
develop across the region. A Level 2 of 4 (Slight) risk for
flooding is in place and the Flood Watch continues through Friday
evening. With already saturated soils, additional flooding is
possible and it wouldn`t take much to get runoff. Saturday will
feature continued rain chances as the trough remains situated over
Texas, with widely scattered showers and storms expected,
however, the flooding threat looks lower as deeper tropical
moisture is kicked further southward.

.LONG TERM...
(Saturday night through Thursday)
Issued at 124 AM CDT Fri Oct 2 2026

On Sunday, PWATs start to notably trend down as northerly flow
from the sfc to 850 mb increases as the 500mb trough breaks down
and weak west-northwesterly flow resumes. A few showers or storms
are possible still, despite decreasing moisture, primarily over
the eastern half of South Central Texas. By Monday, dry weather is
expected for all of South Central Texas as highs climb into the
lower 80s each day through Thursday along with plenty of sunshine.

.AVIATION...
(12Z TAFS)
Issued at 542 AM CDT Fri Oct 2 2026

Scattered showers and thunderstorms will continue today mainly
impacting I-35 terminals through this evening. Conditions have
dropped as low as LIFR this morning but should briefly rebound to
VFR this afternoon most locations except over the Hill Country into
KAUS. Conditions deteriorate again tonight with continued rain
chances over the area, though confidence is low on exactly where
activity will be. Showers should build westward this evening
eventually impacting KDRT. MVFR to LIFR conditions return again late
tonight into Saturday morning.
