  will continue tonight and will be capable of spreading farther 
  inland on Monday. 

- Rain chances increase into Tuesday, with a few storms possible,
  as moisture increases and a front approaches the area. Dry

.DISCUSSION...
Issued at 206 PM EST Sun Nov 30 2025

Tonight-Monday...A cold front moving through the southeast U.S. will 
eventually stall across to just north of north FL into Monday. A 
moderate low level onshore flow will continue across east central FL 
and combine with sufficient moisture at or below 850mb to produce
isolated to scattered over the coastal waters. This activity will
continue to push onshore along the coast tonight through early 
Monday and then spread inland through Monday afternoon. Rain 
chances still remain on the lower end, around 20-30 percent. 
Overnight lows will be mild in the 60s, with highs still near to 
above normal in the upper 70s to low 80s. 

Tuesday...Low pressure at the surface will develop near the northern 
Gulf coast along the stalled front Monday night and lift NE as a 
trough aloft shifts from the central to eastern United States. 
Scattered to numerous showers and isolated storms will move east-
northeast across the area and offshore ahead of the front during the 
daytime Tuesday. Increasing W/SW winds around 30-45 knots from 925-
500mb may allow any storms that develop across areas mainly north of 
Okeechobee County and the Treasure Coast to produce strong wind 
gusts, up to 40-55 mph. Instability will be the overall limiting 
factor with stronger storm potential, as SBCAPE looks to remain 
below 500 J/kg. Rain chances continue to range from around 60-70% 
near to NW of I-4 and 40-50% to the south. Into Tuesday night any 
convection should shift offshore as front pushes through central FL. 

Breezy and warm conditions forecast Tuesday, with highs several 
degrees above normal in the low to mid 80s for most locations. 
Temperatures will fall as low as the 50s, mainly north of Orlando by 
late Tuesday night, with lows in the 60s forecast near to south of 
Orlando. 

Wednesday-Sunday...High pressure will gradually build in behind the 
front to the north of Florida. Northerly flow Wednesday through 
Thursday will continue to transport drier/cooler air into central 
Florida, with rain chances remaining out of the forecast and 
temperatures near to slightly below normal. Highs will be in the 70s 
with overnight lows in the 50s most locations. However, temps may 
fall as low as the upper 40s northwest of I-4 Wednesday night. Dry 
conditions prevail into Friday as winds veer onshore and allow temps 
to gradually rise into late week. Highs will range from the upper 
70s to low 80s, with lows Friday night in the low to mid 60s. 

There remains some forecast uncertainty into next weekend as another 
front approaches Florida. The GFS stalls this boundary across north 
FL, while the ECMWF moves the boundary through into Saturday night. 
Either way rain chances will return to the forecast. Currently have 
PoPs rising to 30-50% from Brevard/Osceola counties northward on 
Saturday, and 20% across Okeechobee County and the Treasure Coast, 
with rain chances then ranging from 30-40% areawide on Sunday. 
Temperatures will continue a warming trend into Saturday, with 
highs in the low to mid 80s for much of the region, and if front 
is able to push through during the weekend as the ECMWF suggests, 
then highs will fall back to more normal values in the 70s on 
Sunday.

.MARINE...
Issued at 206 PM EST Sun Nov 30 2025

Tonight-Monday...Seas at Buoy 41009 have reached up to 5.6 feet at 
times today, which indicates there may be a little more coverage of 
the 6 foot seas over the offshore waters. The NBM/WNAWAVE10 have a 
better handle on this than the NWPS, with the guidance suggesting 
that seas up to 6 feet may linger offshore through early this 
evening. Have therefore added small craft exercise caution to the 
entire offshore waters with the latest update. Also, increased rain 
chances based on latest radar trends and added a slight chance for 
thunderstorms across the offshore waters of the Treasure Coast where 
instability is a little higher and where we have already seen 
some lightning strikes with this activity. 

Isolated to scattered showers will continue across the waters 
tonight into Monday as east-northeast winds up to 10-15 knots 
continue. Instability decreases over the gulf stream waters tonight, 
so lightning potential looks much lower. Seas will range from 3-5 
feet overnight tonight through Monday. 

Tuesday-Friday...Low pressure will lift northeast across the 
southeast U.S. dragging a cold front through the waters Tuesday 
night. Boating conditions will deteriorate into Monday night as 
onshore flow strengthens to 15-20 knots offshore. Winds then veer to 
the S/SW through Tuesday and increase up to 15-25 knots, with seas 
building to 4-6 feet as front approaches. Scattered showers and 
isolated storms ahead of the front will move through the area 
Tuesday, with a few storms having the potential to produce strong 
wind gusts and lightning strikes as they shift quickly offshore. 

W/NW winds actually decrease some behind the front, but will still 
remain up to 15-20 knots offshore Tuesday night. High pressure will 
gradually build in behind the front with drier conditions forecast 
and winds decreasing below 15 knots through mid to late week. Winds 
will be out of the north Wednesday-Thursday and then become 
onshore by Friday.

A few showers will remain possible through this afternoon along
the coast from MLB southward. Have included VCSH for
MLB/VRB/FPR/SUA, while areas to the north and inland are expected
to remain dry. Additional showers will be possible along the coast
Monday from late morning into the afternoon. Brief MVFR reductions
have been observed when the occasional shower reaches a terminal.  
Otherwise, VFR conditions prevailing. Onshore flow continues, with
winds 10 kts or less each afternoon and light winds overnight.
