.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.

Issued at 1136 PM CST Mon Dec 15 2025

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.
