...New AVIATION...

.SHORT TERM...
(Tonight through Friday night)
Issued at 1036 PM CDT Wed Jul 2 2025

High pressure across the Gulf continues to build through the end
of the week, with drier air gradually cutting off rain chances
before most Independence Day celebrations. Most of any leftover
showers remain generally light tonight, with the best chance of
rain shifting further north and coastal to offshore into early
Thursday and across the brush country on Friday. Still expect near
normal highs and lows, with cloud cover slowly diminishing
through Friday. The humidity will help drive a Moderate (level 2
of 4) Heat Risk across the RGV through Independence Day.

With it being a holiday weekend, nice weather, and a very
borderline rip current situation due to wave heights around 3 ft
and swell period at times reaching above 5 seconds, will bump up
the rip current risk to moderate Thursday and Friday for some
additional awareness.

.LONG TERM...
(Saturday through next Thursday)
Issued at 1036 PM CDT Wed Jul 2 2025

The mid-level ridge pivots back across the Desert SW through the
holiday weekend, allowing weak 500mb low pressure to nestle along
the lower Texas coast and some low level moisture to bring back
some rain chances. Above normal PWATs return Saturday into
Wednesday, increasing POPs each afternoon towards 20 percent,
mainly along the sea breeze, especially Monday and Tuesday. Drier
air arrives by mid to late week as high pressure briefly builds
again. Expect near to slightly above normal temperatures through
next week.

.AVIATION...
(06Z TAFS)
Issued at 1219 AM CDT Thu Jul 3 2025

Generally a mixture of VFR and MVFR ceilings are expected for the
next several hours until about mid-morning in which ceilings are
then expected to rise to more VFR conditions. Southeasterly winds
are expected to continue through the period as well and become
gusty during the afternoon hours. While showers and thunderstorms
are possible, confidence was too low to include in the TAF
package.

.MARINE...
Issued at 1036 PM CDT Wed Jul 2 2025

Now through Next Thursday...Surface high pressure generally holds
across the Western Gulf with light to briefly moderate
southeasterly winds through the forecast period, allowing seas to
gradually diminish by the weekend and remain favorable through
Thursday. Isolated showers and thunderstorms offshore gradually
taper off through tomorrow before returning again Monday through
Wednesday.
