KEY MESSAGES

Updated at 1239 AM EST Fri Dec 12 2025

- Mostly dry and seasonable weather for the remainder of the week.

- High risk of rip currents continues today for all Palm Beaches.

UPDATE

Issued at 111 PM EST Thu Dec 11 2025

Frontal boundary moving through South FL today which will bring a reinforcing shot of cooler and drier air to the region tonight. Lows tonight will be in the 40s around the lake region and 50s for the rest of South FL. High pressure will be in control through Friday and then moisture starts to increase this weekend bringing the threat of showers back into the forecast this weekend, especially on Sunday as a warm front lifts north across the region. Another cold front crosses South FL early next week which will bring dry conditions back to the area for a couple days before moisture increases the middle of next week as the low level flow becomes easterly.

Temperatures will be on a roller coaster over the next week with below normal temps through Friday, around normal this weekend, and then slightly below normal again early next week.

SHORT TERM

(Today through Friday) Issued at 335 AM EST Thu Dec 11 2025

A post-frontal air mass is now spreading across the state with northerly flow increasing dry/colder air advection from the north as high pressure establishes over the SE CONUS. 00Z MFL sounding data already depicted a significantly dry atmosphere above 1 KM, and PWATs dropping to around 1 inch.

The air mass will also become much more stable today and through the short term with POPs near zero each day. Meanwhile, the colder air will bring down afternoon highs, with low-mid 70s across much of SoFlo today, and mid-upper 70s Friday. Ensembles and global solutions expand the ridge across the region on Friday, with winds over SoFlo remaining generally northerly light to moderate flow, and becoming light while veering east on Friday.

All in all, expect a very enjoyable weather pattern during the next couple of days.

LONG TERM

(Friday night through Wednesday) Issued at 335 AM EST Thu Dec 11 2025

In general, high pressure will remain in firm control of the area weather through Saturday, with the air mass gradually warming up into the low 80s. Low POPs remain in the grids for, with maybe a few isolated to scattered showers developing ahead of a weak frontal passage. But even that should remain fairly limited.

Uncertainty remain in model guidance regarding the forecast scenario, and including any lingering moisture on Monday. Some solutions still hint at the potential development of an upper-level disturbance over the Gulf waters. This feature seems to migrate eastward and reach the peninsula early next week and dragging moisture into the area. The timing and intensity of its potential impacts remain uncertain, and latest NBM guidance came fairly dry for the first half of next week.

Morning lows are expected to remain in the mid 50s over the interior, and mid 60s along the coasts.

AVIATION

(06Z TAFS) Issued at 1240 AM EST Thu Dec 11 2025

VFR prevails at all terminals through the next 24 hours. Light and variable flow will become easterly 8-10 kts after 15Z. A gulf breeze may briefly shift winds at APF to a westerly flow after 18Z. Light and variable flow returns tonight.

MARINE

Issued at 335 AM EST Thu Dec 11 2025

Moderate northerly to northeasterly winds will prevail across the local waters over the next couple of days as a frontal boundary lingers over the FL straits. A few showers may return to the southern Atlantic waters by Saturday. Seas will range from 3-5 ft each day.

BEACHES

Issued at 335 AM EST Thu Dec 11 2025

A high risk of rip currents continues for all Palm Beach county beaches today as a northeasterly swell increases along the coastline.
