.SHORT TERM...
(Tonight through Sunday night)
Issued at 124 PM CDT Sat Aug 8 2026

Given similar synoptic flow and low-level conditions compared to the
last few days, another period of isolated showers should accompany
this evening`s seabreeze over the Coastal Plains and eastern I-35
corridor. Most will stay dry, but a brief window of gusty winds,
rain, and perhaps a few rumbles of thunder would be in store for the
few experiencing a shower. Another area of showers is possible in
the evening north of the Hill Country and Austin area, in tandem
with an area of weak convergence aloft, but confidence in this
reaching our area is lower. Tonight stays mild with lows in the 70s.

Sunday should play out similarly. It will be a dry and sunny day for
most across South Central Texas with highs in the mid 90s to near
100F, with heat indices in the low 100s up to around 108F in the
Coastal Plains. Z500 heights are slightly lower Sunday, so there may
be a slightly better opportunity for isolated puffs of shower
development between the eastern Hill Country and the Coastal Plains.
This could occur both along the leading edge of the evening
seabreeze and independent of the seabreeze due to the presence of a
narrow filament of mid-level vorticity aloft. Still, we expect
coverage to be sparse and thus rain chances are only about 15 to 20
percent at best and limited to the afternoon and early evening.

.LONG TERM...
(Monday through next Saturday)
Issued at 124 PM CDT Sat Aug 8 2026

Hot and mostly dry summer weather should stick around for the
foreseeable future. Isolated seabreeze showers remain possible each
afternoon and early evening over the Coastal Plains and eastern I-35
corridor, but those chances will start to diminish as ridging
intensifies over our area during the week. Warmer mid-level air
associated with this strengthened ridging is expected to arrive
around Tuesday and suppress opportunities for rain from then onward.

Daytime highs are forecast to inch up some as the warmest of this
air expands across South Central Texas mid to late week. Ambient
temperatures during this stretch are forecast to reach the 100-102F
range for many areas each day. Apparent temperatures with Gulf
moisture staying in place could necessitate Heat Advisories later in
the week as values above 108F are possible across areas mainly east
of I-37/I-35. The outlook for the upcoming weekend and through mid
August looks quite dry and hot at this range without much indication
in ensemble guidance that ridging will move out of the area.

(00Z TAFS)
Issued at 621 PM CDT Sat Aug 8 2026

Primary change was to introduce a TEMPO group for MVFR CIGs at AUS
Sunday morning. Confidence has increased that stratus will become
broken for a short time 12Z-14Z Sunday. Winds will remain light at
less than 10 kts overnight but increase to around 10-12 kts again
Sunday afternoon. MVFR ceilings develop at SAT and SSF and should
break by 15Z Sunday.
