.SHORT TERM...
(Tonight through Saturday night)
Issued at 104 PM CDT Fri Aug 14 2026
Area Doppler radars are showing isolated light to localized heavy
showers and even a few thunderstorms across Goliad County over the
Corpus Christi area. This activity is forecast to move to the north
for the rest of this afternoon and early evening as new showers and
storms develop with the aid of the sea breeze through that time
frame. Most areas are likely to stay dry, however, those Lucky
ones have a chance to get a trace to one quarter inch with a few
locations getting up to half inch. High`s today are forecast to
reach the mid to upper 90s over most places and up to 103 across
the southern portion of the Rio Grande Plains. With the cloudiness
and the chances of rain, heat index values are mostly likely to
stay below the 108 mark. However, there is a chance for a few
locations to briefly get to 108. Otherwise, partly cloudy skies
are forecast for tonight with moisture increasing overnight
through Saturday morning resulting in cloudy skies.
Clouds begin to dissipate mid to late morning with mostly sunny
skies for the afternoon. Saturday`s highs to range from the mid to
upper 90s and up to 103 across the southern Rio Grande Plains.

.LONG TERM...
(Sunday through next Friday)
Issued at 104 PM CDT Fri Aug 14 2026
The strong upper level ridge across the Southern Plains and Lower
Mississippi Valley is keeping the local area dry and hot for the
rest of the weekend into at least the middle of next week.
Temperatures are likely running above normal values around 3 to 4
degrees. With drier air moving into the area for the period, heat
index values should stay on check and below heat advisory criteria
for the most part.

.AVIATION...
(18Z TAFS)
Issued at 1212 PM CDT Fri Aug 14 2026
VFR conditions persist this afternoon through about midnight with
moderate to occasionally breezy south-southeasterly winds. Gusts
of 20 to 25 kt will occur at times. This afternoon has the low
chance for spotty isolated showers along with perhaps a stray
thunderstorm near and east of the Balcones Escarpment but overall
probabilities and confidence for any impacts at the terminals is
too low to include within the TAF package. Later overnight into
Saturday morning should see an area of low clouds develop with
MVFR ceilings. Locations near the Rio Grande, including KDRT, has
lower confidence on seeing MVFR conditions and trends later for
these locations after sunrise. VFR flight conditions return to
all sites by Saturday afternoon.
