.KEY MESSAGES...
Updated at 549 AM CST Thu Dec 25 2025

  - Dense fog will reduce visibilities across the area each night
    through the weekend. This will result in hazardous travel and
    motorists are urged to use caution when driving. Dense marine
    fog will also persist through the remainder of the week.

  - Well above average temperatures are expected to continue
    through the remainder of Christmas week and into the weekend.
    A strong cold front brings an end to this warmth Sunday night,
    with cold weather products potentially being needed for
    Monday and Tuesday nights.

.DISCUSSION...
Issued at 1114 PM CST Wed Dec 24 2025

An anomalously strong upper ridge anchored over the central US
continues to be the dominant synoptic feature over our area
through Sunday. This, along with surface high pressure directly
overhead, is giving way to a warm and humid Christmas week. The
primary impact we continue to monitor is the development of dense
fog each night through Saturday night. Satellite imagery at
issuance time shows that fog has already developed across much of
the area, including over our local bays, sounds, and adjacent
nearshore Gulf waters, and numerous observation sites have already
dropped to a quarter mile visibility or less. A Dense Fog
Advisory remains in effect for all land areas through 11 AM. In
addition, a Marine Dense Fog Advisory is in effect for all local
bays and sounds, and nearshore Gulf waters out 20 NM through Noon
for visibilities dropping to below 1 nautical mile. Similar to
yesterday, considering that dew points today are forecast to rise
into the low to mid 60s during the daytime hours, moving over
water temps in the upper 50s, cannot rule out the possibility of
dense sea fog lingering into the afternoon hours. We will monitor
satellite/observations throughout the day and, if necessary, will
extend the Marine Dense Fog Advisory. Additional advisories will
likely be needed for tonight. Highs through Sunday will top out in
the mid to upper 70s (low 70s along the immediate coast) and lows
through Saturday night will only drop into the 50s.
Climatologically speaking, these temperatures are roughly 10-15
degrees above average over coastal counties and an impressive
15-20 degrees above average for interior counties.

The pattern finally begins to change by next week as a longwave
trough deepens over the eastern US. This trough will help to send
a strong cold front southward, sweeping through the local area
sometime late Sunday night/early Monday morning. At this point,
guidance suggests that the best forcing from the upper trough
looks to remain well to the north of the local area. That being
said, moisture pooling out ahead of the front should help to
support the development of some scattered shower activity. Once
the front passes through, a much colder and drier airmass filters
in from the north. Temperatures early next week will plummet by
roughly 20 to 30 degrees from where they were over the weekend! In
fact, we may even need to consider cold weather products for
Monday and Tuesday nights, with wind chills potentially dropping
into the teens and lower 20s. We look to close out 2025 with highs
in the 50s and lows in the 20s and 30s. A Low Risk of rip
currents will be in place through the period. /96

.AVIATION...
(12Z TAFS)
Issued at 549 AM CST Thu Dec 25 2025

Nearly every METAR across the region is reporting VLIFR conditions
due to widespread dense fog, with the exception of a sliver of VFR
conditions along coast of northwest Florida. The fog should remain
in place into the late morning hours before dissipating sometime
between 16z-18z. VFR conditions should briefly return during the
afternoon hours for much of the area. However, a few localized
spots of IFR or lower visibilities could linger through the
afternoon along the immediate coast due to dense sea fog
continuing over local area bays and sounds. Another round of dense
fog should develop this evening. Calm winds this morning will
become a light southwesterly flow by this afternoon. /22

.MARINE...
Issued at 1114 PM CST Wed Dec 24 2025

Dense sea fog will continue to develop each night through the
remainder of the week across local area bays and sounds, as well
as the nearshore Gulf waters. Light and variable winds today will
become a light southwesterly flow tonight. This pattern will
continue through the remainder of the week and into the weekend.
