.DISCUSSION...
Issued at 1136 PM CST Mon Dec 15 2025

With onshore flow back in place, we should see temperatures warm
up as moisture returns. As PWs climb back above 1 inch another
mid-upper level trough will swing through the state tonight into
Wednesday, bringing scattered showers/storms back into the
forecast. With any breaks in this rainfall, we`ll also need to
keep an eye out for sea fog along the coast beginning as early as
later tonight/Wednesday morning. Wednesday night into Thursday
morning will be the main timeframe to watch for sea fog due to
lower rain chances and stronger moisture moving in from the gulf.
The next cold front will push through the area Thursday
afternoon/evening, resulting in another brief cool down. This cool
down won`t be as impressive as with the previous front with lows
for Friday morning anticipated to drop into the upper 30s/lower 50s.

Onshore flow is anticipated to quickly return Friday night with
temperatures warming up once again through the weekend into early next
week. Highs this weekend will are currently slated to reach the
70s/lower 80s with lows in the upper 40s/60s. Sea fog may also
develop along the coast during this period as well, spilling
inland during the overnight/early morning hours.

(12Z TAF Issuance)
Issued at 503 AM CST Tue Dec 16 2025

VFR conditions will generally prevail through today with the
exception of some low clouds (around 2500ft) impacting GLS this
morning. Clouds are expected to increase through the day today,
but should remain above 5000ft. Once the sun sets, the clouds will
begin to lower with MVFR conditions with CIGs down to around
1500-2500ft between 4-6z tonight. Ceilings may begin to drop down
to below 1000ft around daybreak Wednesday and remain low through
at least the morning hours. In addition to the lowering CIGs,
patchy fog will be possible.

Isolated showers will begin to pop-up late tonight (around 7-9z)
with coverage expected to increase by daybreak. Isolated
thunderstorms will also be possible, first along the coast during
the overnight hours and then for most of the area during the day
on Wednesday.

SE winds will prevail today around 6-10kt with light, variable
winds expected overnight.

Light to moderate southeasterly winds are expected through mid week.
As moisture funnels into the area, scattered showers will return by
later this evening. In between showers, we`ll need to watch out for
sea fog tonight through Wednesday morning at the absolute earliest.
Wednesday night into Thursday will be the main time frame to
watch for sea fog, as conditions appear more favorable. A cold
front should push off the coast Thursday night with caution flags
and Small Craft Advisories possible in it`s wake. Winds quickly
shift easterly on Friday, then southeasterly Friday night into the
weekend. With the return of onshore flow, we`ll have to watch for
sea fog as early as Saturday morning.
