.AVIATION...
(12Z TAFS)
Issued at 613 AM EST Thu Dec 25 2025
Some patchy fog this morning could briefly affect TAF sites, but
whatever does form is expected to lift by 14Z. VFR will then
prevail through the rest of the day. For tonight, fog chances look
slightly better compared with today and fog will continue to be a
concern for the next few nights.

.DISCUSSION...
Issued at 249 AM EST Thu Dec 25 2025

Through the rest of the week and the upcoming weekend, upper level
ridging will hold in place across the Gulf waters and Florida
Peninsula, while the surface ridge currently centered over the
northern Gulf will gradually shift south into the eastern Gulf by
this weekend. This pattern will favor warm and sunny afternoons
with negligible rain chances and light winds. The main weather
concern will come from fog developing late each night, lifting out
just after sunrise each morning. The greatest fog coverage is
forecast to be over the Nature Coast counties and in low lying
and normally fog prone areas farther south.

The pattern will change early next week as a deep upper level trough
digs into the eastern US, pulling a surface cold front into the
Florida Peninsula Monday night or Tuesday. A few showers will be
possible with this front Monday night, but moisture ahead of the
front does not look to be sufficient for more than a slight
chance of rain. While some cooler air could already be advecting
in by daybreak on Tuesday, models have been slowing down with this
frontal passage, so the coldest air does not look to arrive until
Tuesday night when freezing temperatures will be possible over
the Nature Coast counties.

.MARINE...
Issued at 249 AM EST Thu Dec 25 2025

High pressure over the northern Gulf will settle south across the
waters by this weekend. This will keep winds around 10 knots or
less, with rain chances near zero. A cold front will push into the
waters Monday night, bringing a 20-30 percent chance of showers
and will increase winds to around Small Craft Advisory levels by
Monday evening.

&&

.FIRE WEATHER...
Issued at 249 AM EST Thu Dec 25 2025

No humidity concerns through the rest of the week and the upcoming
weekend. Some patchy fog will be possible each of the next several
days during the late night and early morning hours.
