.AVIATION...
(12Z TAFS)
Issued at 647 AM EST Sat Dec 6 2025

Widespread dense fog continues to impact all terminals through 15Z
with LIFR CIGs/VSBYs. The low ceilings and fog will lift by mid
morning with VFR conditions expected the remainder of the day. Fog
and low ceilings are possible once again early Sunday morning, so we
will likely see more impacts to the terminals during that time as
well.

.DISCUSSION...
Issued at 1233 AM EST Sat Dec 6 2025
Very favorable conditions the remainder of the night for areas of
dense fog to develop. A dense fog advisory has been issued until
10 AM across all of west central and southwest Florida including
the near shore waters including Tampa Bay and Charlotte Harbor. A
narrow band of light showers is currently located just north of
Tampa Bay and the adjacent coastal waters and is currently aiding
in mixing the boundary layer in that region preventing fog
formation. However, as the night progresses and the showers
dissipate, boundary layer conditions will become favorable for fog
development in this region as well.

The fog will lift by mid morning across the forecast area...but
may linger over the waters a bit longer. A chance of showers will
develop Saturday afternoon mainly from the Tampa Bay area and
north.

Over the weekend, an U/L ridge which has been over the region for
the past several days will be suppressed south and east of the
area as a mean broad trough develops over the eastern half of the
U.S., which will gradually sink south over the Gulf and Florida.
An associated cold front over the southeast U.S. will also
gradually sink south across the Florida peninsula late in the
weekend, with an increasing chance of showers and possibly a few
thunderstorms late Sunday and Sunday night.

Surface high pressure will build over west central and southwest
Florida in the wake of the cold front Monday and Monday night with
drier cooler air advecting over the area on gusty north to
northwest winds. The area of high pressure will hold over the
region through mid week.

The U/L trough/lower heights will persist over the forecast area
through mid week, which will keep temperatures near climatic
normals with highs in the mid to upper 60s north to the mid 70s
south...and lows in the 40s north, lower to mid 50s central, and
upper 50s to around 60 south. A gradual warming trend will develop
late in the week.

.MARINE...
Issued at 1233 AM EST Sat Dec 6 2025
High pressure will hold over the waters today with winds and seas
below cautionary levels. A cold front will push across the waters
late in the weekend with winds shifting to the north/northwest in
the wake of the front and increasing to cautionary levels.
Winds/seas will subside Tuesday and Tuesday night.
