.DISCUSSION...
Issued at 1115 PM CST Wed Feb 25 2026

Wednesday was quite windy across SE Texas with widespread peak
wind gusts around 30-40mph with the highest gust being reported at
the Angleton ASOS (KLBX) with a peak gust of 55mph shortly before
1pm. Breezy conditions will continue through around sunrise
Thursday, but then an approaching cold front front the north with
weaken the pressure gradient across the area, thus lowering the
winds through the day. Otherwise, expect mostly cloudy skies and
high temperatures in the low to mid 80s across most the area.
Patchy fog will be possible beginning late Thursday evening into
Thursday night, especially along the coast. Once the fog is
through, the fog threat will end. This FROPA will be a dry one
with little to no rainfall expected, other than a slight chance of
isolated showers along the coast Thursday night.

Friday will see clearing skies and begin with light northerly
winds that quickly become easterly through the afternoon, then
southeasterly by sunset. A return to lower relative humidity
values is also expected on Friday with afternoon minimum values
in the 30-40% range for most inland portions of the region, and
only modest improvements are expected through the weekend.

No significant pattern change is expected through the start of next
week with ridging building aloft and light southerly flow at the
surface. This will keep high temperatures in the low to mid 80s
through at least Monday. Increasing cloud cover is expected by
Tuesday as the upper-level ridge begins to slide to the east, so
may see a slight decrease in afternoon high temperatures.

.AVIATION...
(12Z TAF Issuance)
Issued at 525 AM CST Thu Feb 26 2026

MVFR cigs over most SE TX TAF sites through around 15Z this
morning, then gradually lifting and scattering for most inland
locations. Winds will be southerly at around 10 knots in the
morning and then become VRB during the afternoon as a dry, weak
cold front moves through. Winds will remain light and VRB tonight.
Low cigs will return Thu night and areas of fog will develop
overnight into early Fri, leading to IFR-MVFR vis/cigs.

.MARINE...
Issued at 1115 PM CST Wed Feb 25 2026

Moderate to strong onshore winds will continue through daybreak
Thursday, then slowly decrease through the morning. Seas, which
have climbed to 7-10ft, will also lower through the day on
Thursday, but at a slower pace than the winds. So, have extended
the Small Craft Advisory for the coastal waters through 18z, but
may even need to be extended further for the offshore waters.
Light onshore flow and seas 4-6ft are expected by sunset Thursday,
but the light winds and increasing moisture ahead of an
approaching weak front will lead to the potential of patchy sea
fog.

Main window for sea fog development will be late Thursday evening
through late Thursday night/early Friday morning when the cold
front slides through ending the sea fog threat. This fog potential
is very conditional: warming SSTs, how quickly moisture can build
ahead of the front, and timing of the slow moving front are all
complicating the forecast. Mariners should monitor the forecast
and current conditions tomorrow night if the fog materializes.

A brief period of light offshore winds will occur Friday morning
behind the front, but the light winds quickly turn easterly by
Friday afternoon, then southeasterly by Friday evening. Light
onshore flow and low seas will prevail through at least the start
of next week.
