KEY MESSAGES

Updated at 625 AM EST Sun Dec 28 2025

- Areas of dense fog expected Sunday and Monday mornings across Southwest Florida. Visibilities could drop below a quarter of a mile, resulting in hazardous driving conditions.

- Dry and warm conditions continue into early next week.

- A strong cold front is forecast to approach early in the week, ushering colder and drier conditions to start the new year.

SHORT TERM

(Today through Monday) Issued at 243 AM EST Sun Dec 28 2025

Mid-level ridging and surface high begin to shift southeastward over the Florida peninsula today as troughing builds over the Rockies. This will help keep conditions generally calm, sunny and dry for South Florida, with very light and variable surface winds and ample dry air along the atmospheric column. High temperatures will hit the low 80s this afternoon, and lows overnight could drop to the low-mid 60s along the East Coast, and into the mid 50s over the interior.

A pattern change approaches early next week as the aforementioned trough quickly progresses eastward, dragging a strong cold front along with it. Most guidance remains in agreement with the front beginning its descent along the FL peninsula on Monday, potentially reaching central Florida by late afternoon. Winds will veer from the west throughout the day in response, and South Florida will experience the last little bit of nice, seasonal warmth this year, with highs in the low 80s. Lack of moisture and forcing will keep chances for rain near zero.

Areas of patchy fog could be possible across the interior once again early this morning given light winds and sufficient low-level moisture. SREF and HREF guidance suggests coverage become dense in nature, with visibility in some areas dropping below one quarter of a mile at times, resulting in hazardous commuting conditions.

LONG TERM

(Monday night through Saturday) Issued at 243 AM EST Sun Dec 28 2025

The aforementioned front will continue its trek south along the Florida peninsula on Tuesday, and should have moved across South Florida by the end of the day. Guidance continues to try and develop some convection ahead of the front, but keeps it mostly focused over the local waters where instability and moisture will be maximized. Behind the front, cooler, drier air will advect over the area as high pressure builds over the region, and temperatures will drop significantly (by about 10 degrees compared to the last couple of days) starting on Tuesday. Highs each day will remain in the low 70s along the East Coast and in the mid 60s over the interior, while the lows could potentially dropping to the upper 30s-lower 40s across the interior and upper 40s-lower 50s each night. This air mass will also be anomalously dry, with PWATs forecast to drop to the 0.4-0.8 inch range (below the 25th percentile). As such, expect cool, sunny and dry conditions to begin 2026!

AVIATION

(12Z TAFS) Issued at 625 AM EST Sun Dec 28 2025

Generally VFR except for fog in Southwest Florida and inland portions of South Florida this morning and again late in the period overnight. Light and variable wind with sea breezes anticipated again today.

MARINE

Issued at 243 AM EST Sun Dec 28 2025

Light to moderate northerly winds will prevail today as a ridge of high pressure remains in place over the area, with seas generally at or below 3 ft. Conditions will begin to deteriorate on Monday as a cold front approaches the region. Winds will increase out of the north up to 15-20 kts across all local waters Tuesday-Wednesday, while seas will build to 5-7 ft. A few showers could be possible with this frontal passage on Tuesday.

BEACHES

Issued at 243 AM EST Sun Dec 28 2025

The Palm Beaches will experience a moderate risk of rip currents this weekend as swell increases.
