.KEY MESSAGES...
Issued at 117 PM EST Wed Nov 26 2025
- A very warm afternoon with near record warmth ahead of an
approaching strong cold front.
- A few showers and maybe a lightning storm are possible this
afternoon, tonight, and tomorrow, south of Melbourne, well ahead
of the front. A few showers may accompany the front, itself,
across the I-4 corridor late tonight. Otherwise a pleasantly
cool and quiet Thanksgiving Day is expected.
- Very chilly Thursday night into Friday morning as temperatures
dropping into the 40s and 50s combined with breezy overnight
winds produce lowest wind chill values in 30s and 40s across
parts of east central Florida.

.DISCUSSION...
Issued at 117 PM EST Wed Nov 26 2025
Current-Tonight...A warm afternoon for late November with near
record warmth in the 80s areawide. Today`s highs will top out near
the middle 80s, several degrees above climo and near record values.
Please see Climate section below for records. A modest "uptick" in
moisture may allow for ISOLD-WDLY SCT showers and ISOLD lightning
storms into tonight well ahead of the front generally south of
Melbourne. A strong cold front, while mostly dry, will push into our
northern coverage warning area late tonight and through the
remainder of ECFL during the morning on Thu. Models do try to "spit"
out some sprinkles/few light showers late tonight across the I-4
corridor and have added a small PoP to match up with neighbors here.
Light SW/WSW winds out ahead of this boundary will slowly veer
WRLY/NWRLY thru the night.
Overnight lows mild and generally in the L-M60s, except U50s for
portions of north Lake/northwest Volusia counties. Low confidence on
fog chances overnight, but greatest prospects would be along the
Kissimmee River and towards Lake Okeechobee (pre-frontal).
Thanksgiving Day...Will monitor for some early morning stratus
clouds and potential patchy fog southward (ahead of the front).
Otherwise, the strong cold front will plow through the remainder of
ECFL during the morning, with highest rain prospects 20-40% south of
a Melbourne-Kenansville line. Isolated lightning storms cannot be
ruled out. Generally a pleasant, albeit cooler, holiday on tap.
Behind the front, max temps will only muster U60s to L70s
along/north of I-4 with M-U70s southward toward Lake Okee, except
80F for much of Martin County. Northerly winds (post-frontal) will
make it feel cooler with speeds gradually increasing to 8-12 mph
across the interior and up to around 15 mph near the coast, with
higher gusts for all during the afternoon. Much drier air will
slowly filter southward in the afternoon - esp northward. This will
lead to sensitive fire weather conditions.
Thu Night-Fri...Cooler and drier air continue to filter southward
during this period. Northerly winds (breezy/gusty) continue to
increase to 10-15 mph areawide overnight (up to 15-20 mph along the
coast on Fri) with frequent higher gusts. This as fairly stout high
pressure builds in from the northwest creating a tighter pressure
gradient behind the most recent front.
Overnight lows into Fri morning in the L40s north/west of I-4 with M-
U40s for coastal Volusia and southward thru the interior and L-M50s
for coastal Brevard/Indian River counties, except M-U50s for coastal
St. Lucie/Martin counties. Lowest wind chill (apparent temperature)
readings overnight Thu/Fri morning will realize U30s north/west of I-
4 with near 40F to L40s across coastal Volusia and southward toward
Lake Okee and interior (W of I-95) portions of Brevard/Indian River
counties. Elsewhere U40s to 50s for coastal Brevard/Treasure Coast.
Conditions will not be favorable for frost development due to the
elevated winds.
Afternoon highs (below normal) Fri only recover into the 60s, maybe
near 70F for portions of the Treasure Coast. The elevated winds and
low relative humidity will lead to continued sensitive fire weather
conditions areawide. Still fairly chilly Fri night into Saturday
morning - with an onshore wind component developing along the coast.
Expect lows to range from the 40s over the interior, with M-U50s for
coastal Brevard/Treasure Coasts - except a few L60s for immediate
St. Lucie/Martin coasts.
Sat-Wed...Previous Modified...Model agreement through the extended
continues to improve. A modest trough swinging through the northern
CONUS will support a developing surface low as it tracks east-
northeast from the Central Plains near to south of the Great Lakes,
and across the southeast Canadian provinces, ushering high pressure
offshore of the Eastern Seaboard. At this time, there are no
significant mid-upper features to push the next cold front into
central FL until at least mid next week. Onshore flow is expected to
develop and deepen early in the weekend lasting until perhaps at
least Mon night/Tue before becoming S/SW in advance of the next low
pressure system. This will support gradual warming through the
weekend and into early next week, and potentially some low rain
chances Sun into the first half of next week.

.MARINE...
Issued at 117 PM EST Wed Nov 26 2025
Thru Tonight...An approaching strong cold front will push into the
local waters overnight. Southerly winds 5-10 kts this evening will
veer NW/N by daybreak Thu morning with speeds gradually increasing
to 10-15 kts at least north of Sebastian Inlet. Seas 2-3 ft, except
up to 4 ft offshore Volusia late. ISOLD to WDLY SCT showers and
ISOLD lightning storms will be possible.
Thu-Fri...Winds increase behind the cold front with seas slowly
responding (building) as well. Boating conditions deteriorate thru
the day/night on Thu. For this forecast package have initiated a
Small Craft Advisory (SCA) for Volusia waters (15Z/10AM, Brevard
waters (18Z/1PM), and finally for the Treasure Coast waters
(18Z/4PM) as a wind surge slowly pushes southward behind this latest
boundary. Expect wind speeds to slowly increase to 20-25 kts (north
to south) with higher gusts. Initial seas of 2-4 ft will build 3-5
ft near shore and 4-6 ft offshore by early Thu evening, becoming 5-6
ft near shore and 6-7 ft (possibly 8 ft) Gulf Stream by daybreak Fri
morning. ISOLD-SCT showers with ISOLD lightning storms forecast Thu-
Thu evening ending southward as drier air filters across the local
waters behind the front.
Sat-Sun...Boating conditions remain poor into Sat, esp Gulf Stream,
as a tight pressure gradient continues between low pressure to the
south and high pressure building into the area from the north. ERLY
winds 15-20 kts and seas building to 4-6 ft. The gradient relaxes
slightly on Sun with onshore winds decreasing to 12-17 kts and seas
subsiding to 4-5 ft. Mainly dry conditions into Sat, then gradual
rain chances return Sun.

.AVIATION...
(18Z TAFs)
Issued at 1252 PM EST Wed Nov 26 2025
Mainly VFR ahead of the front this afternoon, with ISOLD SHRA
moving NE twd the KSUA-KFPR corridor thru 00z. Have continued
VCSH for KSUA and added for KFPR aft 21z. A stray lightning storm
cannot be ruled out late this aftn in the KSUA-KFPR corridor but
probs look very low. For tonight, the front will move toward nrn
terminals after midnight with short range guidance pointing to post
frontal stratus and some low cloud development along and behind the
boundary. Have added prevailing IFR conds at KLEE aft 09z and TEMPO
MVFR CIGs for now at KSFB/KISM/KMCO late tonight. Some MVFR CIGs
may linger north of a KISM-KTIX line into Thu morning (13z-15z).
There will be some low shower chcs ahead of the front Thu morning,
but probs look too low to mention with this package.

.FIRE WEATHER...
Issued at 117 PM EST Wed Nov 26 2025
A strong, but mostly dry cold front, will push through the area
overnight thru early Thu. Fairly strong high pressure follows with
very dry air and cooler temperatures. Sensitive fire weather
conditions will develop with drier air accompanied with increasing
(post-frontal) northerly winds Thu afternoon-Fri. Min RHs Thu
forecast to drop below 40% along and north of I-4, and possibly
below 30% well north, further decreasing Fri to less than 40%
across much of the interior, and less than 30% in Lake County and
portions of adjacent counties. Winds currently forecast to remain
below 15 mph where RHs are lowest. Afternoon smoke dispersion Thu
is forecast to be mostly Poor to Fair due to generally low mixing
heights and weak transport winds, becoming Generally Good Fri.
There are low to moderate (20-40%) chances for showers and low
(around 20%) chances for lighting storms across the southern
counties Thu. Winds shift onshore by the weekend, increasing
moisture and improving fire weather conditions.
