.DISCUSSION...
Issued at 529 AM EST Wed Dec 10 2025
As seen in the Straits of Florida on KBYX, the frontal boundary
that passed through our island chain yesterday is still lingering.
Overnight temperatures neared 70F and are now sitting in the
lower 70s. Nighttime Microphysics depicts mostly cloudy skies.
Along the Reef winds are being recorded at near 10 knots. Showers
associated with this front as expected to diminish as the day goes
on leaving mostly dry conditions for our region.

Tonight, a reinforcing front is expected to push through the
coastal waters. This front will result in northwesterly breezes
becoming north to northeast but remaining gentle to moderate.
Conditions are expected to remain dry through the first half of
the weekend as high pressure builds behind this secondary front.
Early next week the pattern will change while models are
suggesting an increase in moisture and freshening of breezes, due
to an upper- level disturbance developing in the Gulf. Once timing
and confidence increases PoPs will be adjusted, but for now
20-30% chance will remain in the forecast. Stay tuned.

.MARINE...
Issued at 529 AM EST Wed Dec 10 2025
No watches, warnings, or advisories are currently in effect for
the Florida Keys waters. From synopsis, as a frontal boundary
slides eastward and away from the Florida Keys marine zones during
the early morning, breezes will slacken. A second weak front will
push through the coastal waters late today and tonight, with
modestly freshened northwesterly breezes clocking around to the
northeast to east for late week and into the weekend.

.AVIATION...
(06Z TAFS)
Issued at 529 AM EST Wed Dec 10 2025
MVFR conditions are expected to prevail at the terminals through
sunrise, as observed CIGs largely remain below FL020. That said,
there will be occasional flips to VFR as breaks in the low-level
cloud layer pass overhead. These breaks will become more frequent
after sunrise, and so have opted to make VFR the dominant CIG
category after 12z with TEMPO groups for flips back to MVFR through
late morning. Thereafter, VFR conditions will prevail at the
terminals for the remainder of the TAF period. North to northeast
winds will gradually back over to northwest through the morning.

.CLIMATE...
