.SHORT TERM...
(Tonight through Sunday night)
Issued at 143 PM CDT Sat Jun 8 2024

Patchy areas of low clouds this morning have broken up with mostly
sunny skies seen across South Central Texas this afternoon. Triple
digit high temperatures are expected in the far western and
southwestern portions of the area with highs in the mid to upper 90s
elsewhere. Dewpoints will mainly be in the 60s this afternoon,
although a few locations in the coastal plains may only drop into
the lower 70s. These temperatures and lower dewpoints will keep us
out of Heat Advisory criteria today.

Upper level high pressure remains over the northern Gulf tonight
bringing continued southeasterly flow to the area. Models depict an
increase in low level moisture during the overnight period with low
clouds expected to develop in the early morning hours on Sunday,
mainly over the eastern two thirds of the area. Cloud cover looks to
be short-lived, breaking up sometime in the mid to late morning.
Highs will be similar to those of today in the 90s with triple
digits in the west. Dewpoints will be slightly higher tomorrow which
may bring heat indices near Heat Advisory levels especially along
the Rio Grande, possibly into the Rio Grande Plains.

Some low precipitation chances (around 20 percent or less) are seen
as early as Sunday evening over the southern Edwards Plateau as a
weak disturbance moves into the area from the west. Scattered storms
may develop north of the area and move towards South Central Texas
during this period, although there is still much uncertainty in
exact details.

.LONG TERM...
(Monday through Saturday)
Issued at 143 PM CDT Sat Jun 8 2024

A midlevel shortwave trough will ride over the subtropical ridge
Monday and may provide enough lift to generate showers and
thunderstorms. The best chances will be over the Edwards Plateau and
western Hill Country with slight chances along the Rio Grande and
approaching the I-35 Corridor. The shortwave will move off to the
east overnight Monday/Tuesday and the subtropical ridge will
strengthen. Dry weather will return and a warming trend will begin.
Triple digit highs will spread across from west to east south of the
Hill Country reaching the western Coastal Plains by Thursday.
Dewpoint temperatures will remain mainly steady in the upper 60s to
lower 70s keeping heat indices below advisory criteria.

.AVIATION...
(00Z TAFS)
Issued at 630 PM CDT Sat Jun 8 2024

VFR skies should last through around 08Z with a few low MVFR cigs
popping up in a few areas by that time, will show mainly the 10Z to
15Z window for cigs over I-35 which is a compromise between
persistence and the MOS guidances. Diurnal wind trends should be
mostly typical for mid-June with a few afternoon and evening gusts
over 20 knots possible.
