.SHORT TERM...
(Today through Thursday Night)
Issued at 300 AM CST Wed Feb 5 2025

Very light streamer showers are making their way inland from the
Gulf this morning. Most of this is likely not reaching the ground,
or producing more of a mist. This light precipitation can be
attributed to isentropic ascent at the 295K level.

Expecting a very soupy morning as fog blankets the coastal areas
and patchy fog develops in the Brazos Valley. A Dense Fog Advisory
is in effect for portions of Southeast Texas through 10 AM this
morning, after which visibilities should improve.

Continued onshore flow and WAA will contribute to partly cloudy
skies today and Thursday, along with warm daytime temperatures.
Highs will be in the upper 70s to low 80s both today and Thursday.
Lows tonight and Thursday night will dip into the 60s. Foggy
conditions will return tonight and continue into Thursday morning.

.LONG TERM...
(Friday through Tuesday)
Issued at 300 AM CST Wed Feb 5 2025

The muggy/foggy and unseasonably warm conditions will prevail
through at least Saturday as surface southerly flow persists.
Temperatures will be running around 20 degrees above normal with
highs in the low to mid 80s and overnight lows in the mid to upper
60s. Dense sea fog will continue to be widespread in the near shore
waters with the fog increasing in the Bays and coastal inland areas
during the overnight periods. A weak cold front will attempt to move
in from the north on Sunday, but trends in the guidance is having
this front stall/wash out further and further north where it may not
even make it south of the Piney Woods before it stalls. The
uncertainty in the possible FROPA leads to not only uncertainty in
the temperatures Sunday and Monday, but also means that sea fog may
end up lingering into the start of next week. Some light showers are
possible with the FROPA, but PoPs increase Monday into Tuesday as
moisture and PVA increases ahead of our next strong upper level
disturbance approaching from the west.

.AVIATION...
(06Z TAF Issuance)
Issued at 1058 PM CST Tue Feb 4 2025

Dense fog at the coast, while CLL and UTS far inland are actually
still at VFR! In between, a mix of LIFR and IFR conditions as
stratus and fog blanket SE TX another night. This should continue
with a modest degradation through the early morning hours. Most
dramatic will be IFR CIGs emerging at CLL and UTS. Gradual
improvement through the morning, and away from the coast, likely
even a few hours of VFR again returning...at least until the sun
starts going down and we begin the process anew.

.MARINE...
Issued at 300 AM CST Wed Feb 5 2025

Unfortunately, there has not been any substantial change in the
weather pattern with moist onshore flow moving over cool ocean/bay
waters leading to prolonged period of sea fog through the weekend.
Fog will be densest/most widespread during the evening through mid
morning hours each day with some visibility improvement during the
late morning through the afternoon, but patchy fog will even be
possible then. Some spots, especially along the nearshore waters,
may see little to no improvement in visibility during the daytime
hours. A Marine Dense Fog Advisory is in effect through Noon for the
Bays and nearshore waters, but this Advisory may be continued
through the day in the nearshore waters.

Ocean water temperatures should be slowly rising through the
remainder of the week, which may help inhibit sea fog development. A
cold front may move through the coastal waters on Sunday helping to
clear out the fog, however there is uncertainty on how much dry air
will filter in behind the front so patchy sea fog may still linger
into Monday or Tuesday of next week.
