.DISCUSSION...
Issued at 1025 PM CDT Sat Jul 12 2025

An area of high pressure over the Gulf will expand over Deep South
Texas and the Rio Grande Valley. This will keep rain chances very
low (less than 10%). However, a stray shower or thunderstorm with
the afternoon seabreeze still remains possible. Southeasterly winds
are expected to persist over the region through the forecast periods
with winds gusting up to 25 mph possible for mostly the Valley and
right along the coast.

As for temperatures, the low temperatures are generally expected to
be in the 70s for most of Deep South Texas and the Rio Grande
Valley. However a few locations for the extreme Southern parts of
the CWA could approach the 80s. The high temperatures are expected
to generally be in the 90s, however a few places in Starr and Zapata
counties could be in the triple digits. The heat risk for the
forecast period will mostly be moderate (level 2 of 4) for the
region. The heat indices are expected to be in the range of 105-108
and thus below Heat Advisory criteria. However it is still important
to practice heat safety to prevent any heat-related illnesses.

Increasing swell affecting the Lower Texas coast will allow for
moderate risk of rip current for the next several days. Be careful
if venturing into the water and remember rip currents are highest
near piers and jetties.
