.DISCUSSION...
Issued at 234 AM EST Wed Dec 17 2025

Today-Tonight...Ridge axis of high pressure over the Atlantic will
remain north of Florida, maintaining an easterly low level flow
across the region. Mostly cloudy skies are forecast today as cirrus
clouds aloft build eastward and low level moisture trapped below an
inversion near 850mb, generate marine stratocu clouds that will
continue to stream onshore. Similar to yesterday, isolated onshore
moving showers and isolated to scattered sprinkles will be possible.
However, any measurable rainfall looks to remain mostly confined to
the coast. Have kept 20 percent rain chances along the coast for
today into tonight, with a chance of sprinkles mentioned a little
farther inland. Despite the cloud cover, the moderating onshore flow
will continue a gradual warming of temperatures, with highs near to
just a few degrees above normal in the mid to upper 70s. Lows
tonight will range from the low to mid 60s for much of the area, but
may see temps drop into the upper 50s across normally cooler
locations across the interior.

Thursday-Friday...Isolated onshore moving showers will continue to
be possible into Thursday morning. Rain chances then increase into
the afternoon/evening up to 30-50%, as southerly flow increases PW
values up to 1.4-1.7" across the area well ahead of a cold front
moving into the Southeast United States. Scattered showers will
develop across the area and while instability remains rather limited
(CAPE at or below 500 J/kg), an approaching mid level trough may
help generate isolated lightning storms, mainly into the evening.
There is a modest increase in shear as S/SW winds increase to 30-40
knots between 925-500mb, and this may allow any storms that can
develop to become strong, with the main threat being lightning
strikes, strong wind gusts and brief heavy downpours. Rain chances
then diminish into Friday morning as front approaches and eventually
moves across central Florida during the afternoon/evening hours.

Temperatures will continue to rise into late week, with highs above
normal in the upper 70s to low 80s both Thursday and Friday. Lows
Thursday night will be mild, in the mid 60s for much of the region,
and then the passing cold front will lead to much cooler conditions
into Friday night, with lows in the 50s, except mid/upper 40s NW of
I-4.

Saturday-Tuesday...High pressure builds in quickly behind the front,
pushing toward the Mid-Atlantic coast and offshore into Saturday.
This area of high pressure is then reinforced into early next week
as a weak front approaches Florida. Winds quickly veer onshore and
remain out of the east-northeast for much of the period. It looks to
remain mostly dry through the weekend into early next week, but may
see the return of isolated onshore moving showers as airmass
gradually moistens and onshore flow increases, especially into early
next week. Temperatures look to generally remain near to above
normal, with highs mostly in the 70s, except low 80s forecast for
portions of the area Sunday. Lows will be in the 50s to low 60s.

.MARINE...
Issued at 234 AM EST Wed Dec 17 2025

Today-Tonight...Easterly winds around 10-15 knots today will become
southeasterly into tonight, as ridge axis of high pressure across
the Atlantic remains north of the region. Seas will continue to
subside slightly with seas 3-5 feet. Isolated to scattered showers
and sprinkles will continue to be possible across the coastal waters
moving west-northwest and onshore along the coast.

Thursday-Friday...Winds become S/SE into Thursday and S/SW Thursday
night as a cold front moves through the Southeast United States.
Wind speeds increase from 10-15 knots Thursday up to 15-20 knots
offshore into Thursday night, leading to poor boating conditions.
Winds continue to veer to the W/SW Friday morning as front nears the
area, and then switch to the N/NW behind the front Friday afternoon
into Friday night as front moves through the waters. Winds are
forecast to remain around 15-20 knots offshore as front approaches
and then will be closer to 10-15 knots as this boundary moves
through, with seas building to 6 feet well offshore of Volusia and
Brevard counties.

Rain chances increase Thursday into Thursday night, with scattered
showers and isolated storms possible across the waters, especially
into the afternoon and Thursday night. Rain chances then gradually
diminish into Friday as front crosses the waters.

Saturday-Sunday...More favorable boating conditions and mostly dry
conditions are forecast into the weekend. Winds quickly veer
onshore, with speeds forecast to remain around 5-10 knots. Seas
subside to 3-5 feet Saturday to 2-4 feet Sunday.

.AVIATION...
(12Z TAFs)
Issued at 600 AM EST Wed Dec 17 2025

Mainly VFR conditions through the TAF period. Chances for MVFR-IFR
reductions from stratus/fog at the inland terminals now less then
10%, and window of opportunity will close in the next couple
hours. ISO to possibly SCT onshore moving showers capable of brief
MVFR CIGs and IFR VIS impacts will continue today and tonight.
Confidence where/when these will develop is very low, and will
need to play VCSH/TEMPOs by ear. Highest chance in the next 6
hours or so from KMLB-KDAB. There is a low (10%) chance for these
shower to push inland and make it inland to the Orlando area
terminals. Light/VRB winds early this morning settle to the ENE-
ESE at 5-10 kts, up to around 10 kts along the coast in the
afternoon, then become light again late this evening. Winds shift
to the SE- SSE at 5-10 kts, up to around 10 kts along the coast.
