KEY MESSAGES

-As the front pushes eastward and away from the Florida Keys, much drier conditions will overspread today through the remainder of the week.

-A reinforcing frontal boundary will move through tonight into tomorrow resulting in northwesterly breezes becoming north to northeast.

-Breezes will slacken to light to gentle and will fluctuate between gentle to moderate through Monday.

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.
