KEY MESSAGES

Updated at 611 AM EST Thu Dec 25 2025

- Areas of patchy fog will develop across the interior this morning. Visibilities could drop below 1 mile at times.

- Isolated showers will develop across the East Coast this morning, with low-end (10-20%) chances for rain.

SHORT TERM

(Today through Friday) Issued at 301 AM EST Thu Dec 25 2025

A ridge of high pressure will continue to build over the Gulf during the short term period, promoting light northerly surface winds and generally benign weather conditions. Dry air will continue to filter in at the mid and upper levels as the ridge strengthens, which will help suppress any widespread chances for rainfall. However, enough low-level moisture still present along the local Atlantic waters and East Coast (as evidenced via ACARS soundings and satellite imagery) will support a few stray showers developing today. The NBM came in a bit low on PoPs today, so we bumped them up to the 15-20% to account for these low-end chances.

Given light winds and available low-level moisture, radiation fog could form in the early hours of the morning across portions of the interior and southwest FL. SREF and HREF guidance suggests coverage should remain patchy in nature, but visibility in some areas could drop below 1 mile at times, resulting in hazardous commuting conditions.

High temperatures today and tomorrow will top off in the upper 70s and lower 80s, while lows could drop into the low-mid 60s along the East Coast, and into the mid 50s over the interior. These temperatures are a few degrees above normals (which are in the 76- 78F range) but should remain well below record values (in the upper 80s).

LONG TERM

(Friday night through Wednesday) Issued at 301 AM EST Thu Dec 25 2025

The mid-level ridge axis will shift southward over the Florida peninsula through the weekend as stout troughing builds over the Rockies. This will promote continued light northerly flow and generally dry conditions across South Florida this weekend as dry air overspreads the region. Temperatures will remain generally seasonable, with highs in the upper 70s and lower 80s each day, and lows in the 50s over the interior and upper 60s along the East Coast.

A pattern change approaches next week as the aforementioned trough quickly progresses eastward and drags a cold front south along the peninsula. This front is forecast to move across the region sometime between Monday and Tuesday. High pressure will build behind the front, and cooler, drier air will settle over the region, resulting in mild and pleasant weather to end the year and start 2026.

AVIATION

(12Z TAFS) Issued at 612 AM EST Thu Dec 25 2025

VFR continues during he next 24 hours at all terminals. L/V winds will shift ENE around 8 kts after 15Z, and allow for sea breezes to develop along both coastlines near noon. A few passing showers are possible today, but no significant vis/cigs impacts are anticipated. Any remaining VC patchy fog should dissipate shortly after sunrise.

MARINE

Issued at 301 AM EST Thu Dec 25 2025

Light to moderate northerly winds will prevail Thursday and Friday as a ridge of high pressure remains in place over the Gulf. A few isolated showers will remain possible across the eastern half of South Florida today. Seas should remain below 3 ft.
