.KEY MESSAGES...
Issued at 239 PM EST Sat Dec 13 2025

- Patchy to areas of dense fog are forecast for portions of ECFL
  late tonight into early Sunday morning. The greatest potential
  for areas of fog will be along and north of the I-4 corridor.

- The next cold front will push through Sunday evening/night but
  will come through mostly dry. Scattered showers and a storm or
  two will affect Treasure coast/Okeechobee during the day on
  Sunday. Noticeably cooler on Monday behind the cold front.

- Breezy to windy conditions developing Sunday night through
  Monday as north to northeast winds increase across the area.
  These winds will produce very hazardous boating and surf
  conditions early next week, with beach erosion possible. A Small
  Craft Advisory and Gale Watch have been issued starting at 4 pm
  on Sunday.

.DISCUSSION...
Issued at 239 PM EST Sat Dec 13 2025

Rest of Today-Tonight... Upper level low pressure system over the
Great Plains will move into the Great Lakes region today. Surface
high pressure axis, centered across the Great Plains, will continue
to build southeast across the Deep South as high pressure across the
Atlantic waters builds over the Florida peninsula. Locally, dry
conditions will dominate, with no mentionable rain chances. Dry air
will continue to filter across the area, with forecast PW values
around 0.7-1.0" today. Northeast to east winds this morning will
veer east to southeast this afternoon with speeds at 5-10 mph.

Guidance is showing patchy to areas of fog developing late tonight
into early Sunday morning across portions of east central Florida,
mainly from Melbourne to Lake Okeechobee northward and westward,
with areas of fog generally along and north of the I-4 corridor.
Remember if you encounter fog while driving, slow down and use your
headlights. Temperatures will be seasonable to slightly above normal
for this time of year, with afternoon highs in the mid to upper 70s.
Overnight lows will range from mid 50s across the far north to mid
60s across the far south on tonight.


Sunday-Monday... The upper level low pressure over the Great Plains
will move into the Great Lakes region on Sunday before deepening and
moving eastward towards Maine through Monday. At the surface, a
strong high pressure centered over the Midwest will shift southward
into the Deep South on Monday with the axis building over the
Florida peninsula. The frontal boundary across South Florida will
lift northward as a warm front into Sunday. This will result in an
increase in cloud cover as well as a return of rain chances across
the local area. There is a low (20-30 percent) chance of rain from
southern Brevard/Osceola southward on Sunday, with a low (20
percent) chance of lightning storms mainly across the Treasure Coast
and southern Okeechobee county.

The next cold front will push across east central Florida Sunday
evening into Sunday night. This will be a dry frontal passage, with
no mentionable rain chances Sunday night through Monday. However,
winds will increase across the local area as the axis of the strong
high pressure builds over the Florida peninsula, tightening the
pressure gradient and resulting in a period of windy conditions
(especially along the coast) Sunday night into Monday. North to
northwest winds at 5-10 mph on Sunday will increase to 10-15 mph
(and 15-20 mph along the coast) Sunday night with gusts 20-30 mph
through Monday. A wind advisory will likely be needed Sunday night
through Monday. Those strong winds will also result in rough,
pounding surf and minor beach erosion during that time (roughly
encompassing 1-2 high tide cycles). A High Surf advisory may be
needed.

Temperatures will be above normal on Sunday before becoming
noticeably cooler behind the front on Monday. Afternoon highs will
be in the upper 70s to low 80s on Sunday before dropping to low to
mid 60s across the north and upper 60s to low 70s across the south
on Monday. Overnight lows will range from upper 40s across the far
north to low 60s across the far south on Sunday night, and range
from low 40s across the far north and near 60 degrees across the far
south on Monday night.

Tuesday-Friday... A weakening high pressure across the Deep South
will move into GA early on Tuesday before gradually shifting
eastward, moving offshore into the Atlantic ocean by Thursday. The
trailing axis will remain over the Florida Peninsula through the
time period. This will result in north to northeast winds turning
easterly on Tuesday at 5-10 mph as the high settles into the Deep
South before eventually veering east to southeast Wednesday evening
and continuing through Thursday as the high moves offshore. The next
cold front is forecast to approach Friday, first dropping into north
Florida before reaching the far north part of the CWA Friday
night/early Saturday morning. Mostly dry conditions are forecast
through Wednesday, with no mentionable rain chances over land areas
through that time. Isolated to scattered showers will continue to be
possible over the Atlantic waters however. Rain chances return to
land areas on Thursday and Friday, with isolated showers forecast
along the immediate coast of the Treasure Coast both days. The
frontal passage Friday night looks to be mostly dry, with no
mentionable rain chances over land areas.

Temperatures will be on a slight warming trend into late week, going
from seasonable/slightly below normal to above normal by Thursday.
Afternoon highs will generally be in the low 70s on Tuesday, mid 70s
on Wednesday, and upper 70s to low 80s on Thursday and Friday.
Overnight lows will be in the low to mid 50s Tuesday night, mid to
upper 50s on Wednesday night, and upper 50s to low 60s on
Thursday night and Friday night.

.MARINE...
Issued at 239 PM EST Sat Dec 13 2025

Today-Wednesday... (Modified Previous Discussion) High pressure
across the Atlantic waters will produce favorable boating
conditions today. East to southeast winds around 10 KT on today
will veer northwest and increase to 15-20 KT on Sunday. Seas 1-3ft
today will increase to 2-4ft on Sunday. Mostly dry conditions
through today, with isolated to scattered showers and isolated
lightning storms on Sunday.

Winds will increase Sunday night into Monday out of the north as
strong high pressure builds over the waters behind a cold front. The
tight north-northeast pressure gradient will support wind speeds 20-
30 KT with gusts to Gale force Sunday night. Seas will rapidly build
6-9 FT nearshore and up to 12 ft in the Gulf Stream. A Gale Watch
has been issued for the Volusia waters starting at 21Z on Sunday and
going through 12Z Monday. A Small Craft Advisory has been issued for
the Brevard waters for 21Z Sunday, expanding to the Treasure Coast
waters starting at 03Z Monday and replacing the Gale Watch across
the Volusia waters starting 12Z on Monday. The SCA will likely need
to be extended in time for the Gulf Stream waters.  NE winds
decrease 15-20 KT by late Monday before veering E/NE Tuesday at 10-
15 KT, and E/SE on Wednesday. Seas will be slower to subside,
reaching 4-5 FT nearshore Tuesday with lingering 7 FT seas in the
Gulf Stream before decreasing to 3-4ft on Wednesday.

.AVIATION...
(18Z TAFs)
Issued at 1250 PM EST Sat Dec 13 2025

VFR to continue thru at least 03z Sun. ESE winds 5-10 kt (with
occasional gusts 15-20 kt VRB-SUA) become light/variable tonight.
Low-mid cloud cover increases south to north after 03z Sun.,
particularly for VRB/FPR/SUA but could drift as far north as
MLB/ISM. SHRA/TSRA are possible after 04z-06z for Treasure Coast
terminals with MVFR conds at times. Additionally, BR/FG is
anticipated at northern terminals (esp. DAB/SFB/LEE). Some
development cannot be ruled out at MCO/ISM, though cloud cover may
hinder greater coverage of FG.

Conds should return to mostly VFR after 14z Sun., outside of
lingering clouds (perhaps VCSH) south. NW winds increase after 17z
to 8-12 kt.
