.DISCUSSION...
Issued at 246 AM EST Sat Dec 6 2025

Early This Morning... A cold front is analyzed near Lake and Volusia
counties early this morning. Moisture in vicinity of the front has
allowed a deck of low stratus to spread across east central Florida.
Observations across north and west Florida have shown surface
visibility reductions as the stratus slowly sinks. Therefore, fog
remains forecast across much of east central Florida this morning,
becoming locally dense at times. If encountering dense fog on
area roadways, use your low beam headlights, reduce your speed,
and maintain a safe following distance. Persistent cloud cover may
allow fog to linger for a bit beyond sunrise, especially near and
north of I-4.

Today-Monday... The cold front remains draped across the I-4
corridor today, extending into the Gulf. Broad low pressure works to
develop along the boundary in the Gulf this weekend, eventually
passing over Florida before further organizing over the western
Atlantic late Sunday and into Monday. This will pull the stationary
front more cleanly across central Florida on Monday, a bit later
than previous model guidance had indicated. Scattered rain
chances (30-40%) remain forecast in vicinity of the stalled
boundary today, mainly north of a line from Cape Canaveral to Lake
Kissimmee. Rain chances continue into the evening, although
models may suggest some drying for a period into the late
overnight. Although timing and coverage of showers may be more
uncertain Sunday morning, a wet afternoon and evening is forecast,
especially near and north of the I-4 corridor. Scattered rain
chances begin to spread southward toward the Treasure Coast and
Okeechobee late Sunday afternoon and into the overnight. Activity
then clears from north to south Monday into Monday afternoon.
Overall, surface instability looks to remain limited through the
period. Confidence in lightning remains low, although the best
chances look to be across the south late Sunday afternoon where
less cloud cover should allow for better surface heating. A
flooding rainfall threat could be present where multiple rounds
of heavy rain occur. Models key in on areas of Volusia and
northern Lake counties for seeing the highest event totals due to
the proximity of the stalled boundary. Across these areas, models
generally suggest event averages of 1-2" possible through Monday,
and localized higher event totals of 3-4" cannot be ruled out.

Increasing cloud cover and rain chances make for a tricky
temperature forecast through the weekend. Afternoon highs look to
hold above average, in the low to mid 80s, south of the I-4 corridor
where cloud cover and rain chances should generally be less. Areas
further north may see a more wide distribution of temperatures,
ranging the low 70s to low 80s. Northerly winds building behind
the front on Monday will filter a cooler airmass across central
Florida with highs spreading the low 70s across the north and
upper 70s across the far south near Lake Okeechobee. Low
temperatures are mostly forecast in the low to mid 60s.

Tuesday-Friday... High pressure builds across the southeast and into
central Florida Tuesday, and conditions remain mostly dry through
the extended forecast. Highs hold near seasonal into mid week,
mostly in the low to mid 70s. Temperatures then increase into the
mid to upper 70s Friday. Lows mostly in the 50s Tuesday and
Wednesday fall into the upper 40s and low 50s across most areas
Thursday.

.MARINE...
Issued at 246 AM EST Sat Dec 6 2025

A weak cold front stalls near Cape Canaveral this weekend. As a
result, north to northwest winds develop north of the Cape today
while south to southwest winds hold across the southern waters.
Winds mostly around 10 kts, except for a short duration surge of
north winds near 20 kts across the Volusia waters this evening.
Winds become variable Sunday as weak low pressure approaches from
the west. This area of low pressure will work to pull the front
south of Jupiter Inlet Monday with north winds increasing near 20
kts Monday night. Winds quickly diminish into Tuesday, gently
shifting out of the north-northeast. Seas remain generally favorable
ahead of the front, ranging 2-4 ft and occasionally 5 ft
offshore. Poor to hazardous seas build late Monday, increasing to
5-7 ft. This will persist through Tuesday before beginning to
slowly diminish on Wednesday. Scattered showers are forecast
today, primarily north of Cape Canaveral. Coverage increases and
builds further southward on Sunday and Sunday night, clearing from
north to south Monday behind the front.

.AVIATION...
(06Z TAFs)
Issued at 1253 AM EST Sat Dec 6 2025

Low stratus with VIS reductions over the western half of the
peninsula is forecast to spread into the local area through the
remainder of the overnight hours. IFR/LIFR conditions are
expected, with TEMPOs included for all sites from 9-13Z, when
models suggest reductions will be greatest. Low clouds look to
continue after sunrise, lingering until around 16Z for most TAF
sites. A brief period of VFR CIGs is then forecast through the
afternoon, before additional MVFR/IFR CIGs develop after sunset
tonight.

In addition to lower clouds, VCSH has been included for this
evening into the overnight hours, as a front continues to slowly
sag southward. W/SW winds today around 10 kts or less will veer
NW/N after 0Z.
