.DISCUSSION...
Issued at 132 PM EST Sat Nov 8 2025

Current-Tonight... Dry so far this afternoon with temperatures
climbing into the low to mid 80s. While most areas will stay dry
through the remainder of the day, a low chance (10-20%) for a
shower still exists near and west of the Orlando Metro. Overnight,
conditions remain favorable for patchy fog development across
much of east central Florida with models particularly showing
interest across the north interior. Low temperatures will be mild
in the mid to upper 60s.

Sunday... A cold front passes the Florida Panhandle and the Florida
Big Bend on Sunday, approaching central Florida into Sunday night. A
surface ridge axis extending south of the area is nudged eastward,
and light southwest flow holds in place locally. A column of low
level moisture is present within most model soundings while dry air
persists above 700mb. Low level moisture combined with surface
temperatures in the mid to upper 80s should support scattered
showers and storms across portions of east central Florida. CAMs
have keyed in on a cluster of east-northeast moving showers and
storms mostly focused north of Okeechobee and the the Treasure Coast
counties. Here, SPC has outlined a Marginal Risk for severe storms.
DCAPE values approaching 800-1,000 J/kg and linear southwest shear
profiles suggest strong straight line winds as the primary storm
hazard. RAP analysis further suggests 500mb temps falling to -10C or
less, and a small hail threat will also be present. The greatest
support for strong storm development may be realized late in the
afternoon and into the evening as activity originally initializing
near or west of the Orlando metro pushes toward the coast and
interacts with a weak east coast sea breeze. Models suggest activity
diminishing along the coast around 10pm while a few light showers or
sprinkles cannot be ruled out along the frontal passage later in the
night.

Monday-Tuesday... Some 50s begin to arrive near, north, and west of
I-4 Monday morning as northerly winds begin to advect cold
continental airmass behind the front. A temperature gradient will
become apparent Monday afternoon as cool air continues to filter
southward. Monday highs spread the mid 60s across the far north with
areas across the south and near Okeechobee holding in the low to mid
70s. Tuesday will be the coldest morning of the period with most of
the interior seeing lows in the mid to upper 30s. Northerly winds
around 10-15 mph will persist, pushing wind chill values into the
30s and nearing Cold Weather Advisory criteria. Only a gradual
warmup is forecast into Tuesday afternoon with highs holding in the
mid to upper 50s near and north of the Orlando Metro. Further south,
highs mostly spread the low 60s.

Wednesday-Friday... Winds diminish as high pressure builds into the
extended period. Dry conditions will hold in place with no
mentionable PoPs through late week. A warming trend will quickly get
underway with highs recovering to range the upper 60s to mid 70s on
Wednesday, and by Friday, temperatures more widely spread the mid to
upper 70s. Low temperatures remain chilly Wednesday morning with
values in the upper 30s north and west of I-4. Lows then mostly warm
into the 50s by Friday.

.MARINE...
Issued at 132 PM EST Sat Nov 8 2025

High pressure will maintain offshore flow through the weekend,
although a weak sea breeze could allow for a light wind shift along
the coast. Scattered offshore moving showers and storms are forecast
near and north of the Cape Sunday afternoon and into the evening as
a strong cold front approaches the local waters. Northerly winds
around 20-25 kts behind the front on Monday will further increase
to 25-30 kts Monday night. In response seas build 7-9 ft across
the Gulf Stream Monday, peaking 7-10 ft nearshore and 9-12 ft
offshore early Tuesday. High pressure builds mid week allowing
winds to slacken and seas to slowly subside, and favorable boating
conditions quickly return Wednesday.

(00Z TAFs)
Issued at 619 PM EST Sat Nov 8 2025

MCO/DAB IMPACTS:
- Probabilities for fog increasing to medium chance late tonight
  through daybreak Sunday. 40-50% chance of IFR.
- A few storms developing Sunday afternoon. Low potential for
  gusty winds exceeding 35 KT.

Muggy light return flow ahead of an approaching trough will allow
for saturation tonight, and guidance is still pretty aggressive
with fog formation from Orlando to Daytona and northward. TEMPOs
will remain in the TAFs to handle this, but will of course AMD as
trends play out overnight. On Sunday, light southwest winds
continue as VFR resumes over most terminals by late morning.
Ribbon of deeper moisture should be enough to spark scattered
afternoon storms moving SW to NE.

.FIRE WEATHER...
Issued at 132 PM EST Sat Nov 8 2025

A strong cold front is forecast to pass central Florida late Sunday
night. Increasing north winds around 10-15 mph behind the front will
advect a cold, dry airmass into east central Florida early next
week. Min RH values become sensitive on Monday, further falling
below critical thresholds near, north, and west of I-4 on Tuesday.
Winds diminish Wednesday and into to late week as high pressure
builds across the region, but RH values will remain sensitive.
