.DISCUSSION...
Issued at 200 AM EST Sat Dec 20 2025

Today-Sunday...Temperatures are off to a chilly start for many
across east-central Florida, especially north of Interstate 4. There
is a decent gradient from north to south, with values ranging
from the low/mid 50s in Lake and Volusia counties to the mid 60s
to near 70 degrees along the Treasure Coast. Morning lows are
still forecast to dip into the mid/upper 40s across the far north
with 50s and mid 60s farther south. Have a jacket handy for
stepping outside this morning. By this afternoon, sunshine will
help temperatures rebound into the 70s (low 80s around Lake
Okeechobee). We do anticipate some clouds this afternoon,
especially south of Orlando, but having no real influence on
temperatures. Tonight, lows retreat into the 50s to mid 60s for
most (upper 60s Martin County). A few CAMs indicate shower
development is possible near Martin County and Lake O very early
Sunday morning, so trends will be monitored and may lead to a low
chance for precip there overnight.

Similar conditions are forecast on Sunday with light onshore flow
continuing and a mix of some high and mid level clouds. High
temperatures climb a bit higher (especially north), reaching the
mid 70s to low 80s. We`ll keep an eye on the potential for a few
showers over the Atlantic waters, mainly south of the Cape. While
not explicitly outlined in this forecast package, an isolated
shower or two could approach the Treasure Coast Sunday night.
More changes arrive Sunday night into early Monday as a cold
front approaches from the north. Confidence in rain chances
along/ahead of the front remains low, with the most noticeable
change being an increase in northeast winds, especially at the
coast. Onshore flow boosts overnight lows by a degree or two,
still ranging from the mid/upper 50s over the northern interior to
the mid to upper 60s along the southern half of our coast.

Monday-Friday...The early week cold front will slowly sink south
of the area on Monday as surface high pressure expands over the
eastern U.S. A couple of low-end rain chances may be in play for
the holiday week, and confidence is higher in the early week
opportunity. Established onshore flow and an increase in low-level
moisture should build at least a scattered marine stratocu field
over the local Atlantic Monday. These clouds, accompanied by a few
showers, are forecast to push onshore from Monday afternoon
through the day on Tuesday. Coastal locations will be best positioned
to see a few quick-hitting showers, though during the daytime
hours this activity could drift farther inland.

Wednesday promises drier weather overall as the H5 ridge axis
progresses eastward across the Gulf/central CONUS. By Thursday,
guidance is picking up on a residual frontal boundary and very
weak shortwave energy rounding the eastern periphery of the H5
ridge, heading toward the ECFL coast. This is a bit of a change
from 24 hours ago or so. Mentionable rain chances were not
included at this time, but enough low-level moisture and forcing
could reintroduce coastal showers late Wednesday through Christmas
Day. By week`s end, less model agreement exists with the overall
synoptic pattern. Nevertheless, dry weather looks to prevail with
the influence of high pressure overhead.

Temperatures through the holiday week will be pleasant and largely
unchanged from day to day, ranging from the mid 70s to near 80
degrees (south). Overnight lows settle into the upper 50s/mid 60s
Monday night but fall into the 50s for most locations the rest of
the week. In general, H5 height anomalies are hinting at a warmer
Christmas Day for the central and southern U.S. this year.

.MARINE...
Issued at 200 AM EST Sat Dec 20 2025

High pressure over the waters this weekend will provide for
favorable boating conditions and light onshore (E-NE) winds. Seas
fall from 3-5 ft today to 2-4 ft Sunday. An isolated shower or two
cannot be ruled out south of the Cape this weekend, mainly on Sunday
and Sunday night, as another cold front approaches from the north.

As an early week front makes its approach and moves south across
the waters, northeast winds are forecast to increase, reaching
15-24 kt (gusts to 30 kt offshore) Monday and Monday night. Winds
slacken gradually on Tuesday, but mariners can expect poor to
hazardous conditions to start the holiday week and linger through
at least Tuesday morning. Seas build quickly in response, peaking
around 6 to 10 ft Monday night (highest wave heights in the Gulf
Stream). Improving conditions then return mid to late week as
surface high pressure reestablishes itself, leading to a
continuation of light onshore flow.

.AVIATION...
(12Z TAFs)
Issued at 614 AM EST Sat Dec 20 2025

VFR conditions through the TAF period. Northerly wind will veer
northeast by mid-morning with speeds generally under 10 KT. Winds
will then become light and variable overnight before winds become
N/NE and increasing to 5-10 KT by late morning Sunday.
