KEY MESSAGES

Updated at 619 AM EST Mon Dec 8 2025 - Unsettled conditions today as two fronts push through the area. Showers and thunderstorms likely again after noon.

- Hazardous boating conditions could be possible tonight into Tuesday as winds surge behind the frontal passages.

- Drier, cooler weather starting Tuesday as high pressure builds over the region.

SHORT TERM

(Today through Tuesday) Issued at 338 AM EST Mon Dec 8 2025

The passage of a primary cold front early this morning has resulted in unsettled weather for southwest and interior Florida, with showers and thunderstorms that produced a few gusts up to 30 mph and about 0.5-1 inches of rain in some spots. This front will weaken as it gradually drifts southeastward over the next couple of hours, but areas across the East Coast could see a couple of showers and maybe a thunderstorms or so from now until around 11-13z, when the front should have cleared the area.

A secondary front will follow along later today, with scattered showers and thunderstorms possible starting around 15-18z. The bulk of the activity will be most likely in the Lake Okeechobee area, but areas south of Alligator Alley, as well as along the coasts, could still experience a few downpours as the front sags south. This secondary front is forecast to drift south over the FL Straits after 00Z tonight, and northerly winds behind the front will help usher in cooler, drier air over the region. Expect overnight temps to drop to the upper 50s across the interior and down to the mid 60s along the coasts. Comfortable temperatures will also be likely on Tuesday, with highs topping off in the mid 70s.

LONG TERM

(Tuesday night through Sunday) Issued at 338 AM EST Mon Dec 8 2025

The aforementioned front is forecast to remain stalled over the Florida Straits as high pressure builds in over the peninsula, promoting generally fair weather through the end of the work week. Dry, relatively cool air will continue to filter in across the area, with high temperatures each day in the mid to upper 70s and lows in the mid 50s over the interior, and mid 60s along the coasts.

The next cold front to watch could make its approach late next week, although much uncertainty remains regarding timing and intensity, especially given the complex interactions at play over the continental US during this time period. Cluster analysis for days 4- 5 (Thursday-Friday) are in closer agreement regarding a weaker, slower approach from the front, which would likely mean a dry frontal passage with low-end rain chances, and the NBM caught onto that trend this morning, with PoPs below 15% between Fri-Sun. Nevertheless, there is enough of a signal for a slightly stronger system, and with enough low level moisture forecast to linger just south of the area, decided to bump up the chances for precip up to the 15-25% range mainly over the local Atlantic waters and the East Coast.

AVIATION

(12Z TAFS) Issued at 619 AM EST Mon Dec 8 2025

Periods of sub-VFR conditions will be likely throughout the period as two fronts push through the area, with gusts up to 20-25kts possible. Southwesterly winds will gradually veer to the west late this morning and then to the north by the end of today into tonight. VCSH/VCTS after 15Z, lasting into early tonight for now.

MARINE

Issued at 338 AM EST Mon Dec 8 2025

Boating conditions being to deteriorate today as two fronts move across the region. Winds will gradually veer from southwesterly to northerly through the day, increasing up to 15-20 kts by tonight and persisting into Tuesday afternoon. Seas will build as a result, up to 7 ft across the local Atlantic waters, and between 3-5 ft across the Gulf waters. A few showers and thunderstorms will be likely with each frontal passage today, with locally higher winds and seas possible.
