.DISCUSSION...
Issued at 1201 AM CDT Mon Sep 15 2025
Today through Wednesday will be pretty much a copy-and-paste
forecast. Most of the region will be rain-free, but PWATs near
1.5" and daytime heating could lead to a few isolated afternoon
showers or thunderstorms along the sea breeze. Weak disturbances
aloft will approach/pass through eastern Texas beginning Thursday
that continues into the weekend. The coverage of the activity will
be largely dependent on the strength and location of the passing
shortwaves aloft, but just the presence of them nearby will bump
up PoPs to around 20-40% each across the area each afternoon
beginning Thursday through next weekend.
Temperatures will be fairly seasonal through this week with
afternoon high temperatures generally in the low to mid 90s
(cooler at the coast) and overnight lows in the low to mid 70s
(warmer at the coast). Daytime temperatures may cool slightly by
the end of the week depending on how much cloud cover/rain
coverage we get with the passing weak disturbances.

Issued at 517 AM CDT Mon Sep 15 2025
Isolated patchy fog should clear after sunrise. VFR conditions
prevailing during the daytime, with light SE/E winds. Isolated
showers could develop in the afternoon, though chances are too
low to warrant inclusion in the TAF. Variable winds overnight
with brief patchy fog possible again Tuesday morning.

.MARINE...
Issued at 1201 AM CDT Mon Sep 15 2025
Light to occasionally moderate east to southeasterly flow (sustained
10-15kt, occasional gusts to 20kt) will persist through at least
midweek with seas generally between 2-4ft. Isolated showers and
storms over the coastal waters will be possible through midweek
with better chances towards the end of the week.
The persistent onshore flow will lead to higher than normal high
tides through at least the start of next week, peaking at around 3.0-
3.5ft above MLLW at times of high tide.
