.DISCUSSION...
Issued at 120 PM EST Tue Dec 9 2025

Tonight...Lots of clouds were observed in the morning hours south
of Orange, while skies were mostly sunny northward. A drier air
mass is expected to push from the west later today, around 700-300
mb, but some moisture is expected to survive close to the
surface. Some clouds are expected to linger tonight along these
areas. In general, a stationary front lingers well south of the
region, while high pressure maintains a light onshore flow into
the region. The winds are expected to remain from the north-
northeast through at least tonight. The local guidance suggests
mostly fair-weather prevailing, as the air mass remains dry from
700-300 mb. Chances of shower are low, and if any form, should be
focused along the southern counties. Temperatures will cool down
to the low and mid- 50s north of Okeechobee, and above 60 west of
Okeechobee.

From Previous Discussion...

Wednesday-Thursday...High pressure weakens Wednesday as a cold
front drops into the southeast U.S. The weak front then passes
central Florida Thursday before high pressure begins to rebuild
from the west. Only a subtle dip in temperatures will be realized
with highs falling a few degrees below normal Thursday afternoon.
Highs on Wednesday mostly spread the low 70s from Osceola and
Brevard northward, increasing into the mid to upper 70s across
Okeechobee and the Treasure Coast. By Thursday, highs fall into
the upper 60s and near 70 degrees from Orlando northward with
temperatures in the low 70s further south. Low temperatures widely
spreading the 50s Wednesday morning dip into the upper 40s and
low 50s Thursday morning. Can`t rule out a stray coastal shower
from the Cape southward on Wednesday. Otherwise, conditions remain
mostly dry.

Friday-Monday... High pressure further builds across the state
Friday, persisting into the weekend. Low pressure moves offshore the
Mid Atlantic coast early Sunday morning, dragging the next cold
front across central Florida late in the weekend. A much stronger
area of high pressure then builds across much of the eastern U.S. on
Monday. Dry on Friday with modest rain chances creeping back into
the forecast this weekend. Highs near normal late week climb into
the mid to upper 70s this weekend before more widely ranging the 70s
Monday behind the front. Friday looks to be the coolest morning of
the period behind Thursday`s front, and interior lows are forecast
in the mid to upper 40s. Warmer along the coast and across Martin
county with lows in the low to mid 50s. Morning temperatures creep
upward through the weekend, reaching the mid to upper 50s across the
interior and upper 50s to low 60s along much of the coast and Martin
county.

.MARINE...
Issued at 248 AM EST Tue Dec 9 2025

Seas diminish 3-4 ft nearshore tonight with seas up to 6 ft
offshore persisting through late Thursday. Offshore flow develops
mid week briefly increasing 15-20 kts early Thursday as a weak
cold front passes the waters. Generally favorable boating
conditions are then favored Friday and into the weekend. Isolated
to scattered showers are forecast across the waters through
Wednesday, mostly south of the Cape. A period of dry weather
settles into late week.
