.DISCUSSION...
Issued at 244 AM EST Mon Dec 8 2025

Current-Today... A band of organized showers continues to spread
south and east of Lake Okeechobee early this morning with more
isolated to scattered activity persisting further north. Isolated to
scattered showers will continue to clear from north to south
throughout the day as a cold front pushes into south Florida.
Despite clearing showers, cloudy skies look to persist. A
temperature gradient will be in place today as northerly winds
develop behind the front. Areas from Brevard and Osceola counties
northward should see highs mostly in the low 70s, although a few
spots of northern Volusia could touch the upper 60s. Across
Okeechobee and the Treasure Coast, highs more widely spread the mid
70s to low 80s. Temperatures overnight mostly cool into the low to
mid 50s with areas north and west of I-4 falling into the mid to
upper 40s.

Tuesday-Thursday... High pressure builds along the U.S. Atlantic
coast Tuesday, stretching across the southeast and into Florida.
The area of high pressure weakens locally on Wednesday as a cold
front moves into the eastern U.S. The front then decays into early
Thursday as it pushes further south. Some low level moisture
lingers along the Treasure Coast and near Lake Okeechobee early in
the period, keeping some cloud cover around. Otherwise, the
moisture profile remains too dry to support any mentionable rain
chances through mid week. Tuesday will be the coolest day with
highs in the mid to upper 60s near and north of the Orlando metro
with mostly low 70s south. Afternoon highs warm to range the low
to mid 70s on Wednesday but reach the upper 70s near Lake
Okeechobee and across Martin county. Temperatures then cool a
touch on Thursday becoming near normal areawide. Low temperatures
mostly continue in the low to mid 50s through Wednesday morning
with low to mid 40s far north and west of I-4. Cooler Thursday
morning, generally ranging the mid 40s to low 50s.

Friday-Sunday... Surface high pressure is reinforced into Friday.
The next cold front looks to approach or pass central Florida
Saturday before a large area of high pressure builds across the
eastern U.S. late this weekend. Dry conditions are maintained
through the extended forecast period. High temperatures hold
steady near seasonal values, mostly in the low to mid 70s.
However, far south near Lake Okeechobee and across Martin county,
highs again touch the upper 70s. Lows on Friday spread the upper
40s and low 50s, gradually warming into early next week.

.MARINE...
Issued at 244 AM EST Mon Dec 8 2025

Scattered to numerous showers and isolated storms will clear from
north to south today as a cold front passes south of the waters.
Poor to hazardous boating conditions build behind the front as
northerly winds increase to 15-20 kts this afternoon, further
increasing to 20-25 kts across nearshore Volusia and portions of the
Gulf Stream waters. In response, seas build to 6-8 ft in the Gulf
Stream late this afternoon and overnight. Small Craft Advisories go
into effect at 4 PM today for nearshore Volusia and all legs of the
local offshore waters. Winds diminish Tuesday as high pressure
builds, and seas subside to 5-6 ft offshore Tuesday night before
becoming widely 4-5 ft Wednesday night. Dry conditions settle into
mid to late week behind the front.

.AVIATION...
(06Z TAFs)
Issued at 1250 AM EST Mon Dec 8 2025

A weak front will continue to sag southward through the area
through today, with diminishing chances for showers from north to
south. SHRA continuing over the next couple of hours, with VCSH
then prevailing through at least 14Z. Recent CAM runs dry the
Treasure Coast out a bit earlier than other guidance, so will need
to monitor for future updates. Regardless, MVFR/IFR CIGs look to
persist through much of the TAF period and look to clear around 0Z
or later. Breezy northerly winds near 10-12 kts this afternoon
will have occasional gusts to 20 kts, especially along the coast.
Winds are then forecast to remain elevated through the overnight
hours tonight.
