.FOR THE EVENING UPDATE...
Issued at 702 PM EST Fri Nov 28 2025
Canadian high pressure will hold over the region tonight and
Saturday. Mostly clear skies and decreasing winds will create
another rather cold night for much of the forecast area with lows
in the mid to upper 30s north, in the mid to upper 40s central,
and the lower to mid 50s south.

The main hazard will continue over the coastal waters with a
small craft advisory through Saturday night...and along area
beaches through tomorrow morning due to a high risk of rip
currents.

Warming trend on Saturday with some increasing high cloudiness
during the afternoon. Highs in the lower 70s north to the upper
70s south.

.DISCUSSION...
Issued at 1245 PM EST Fri Nov 28 2025

As a trough lifts off the NE coast, the synoptic pattern is
flattening out into a mostly zonal setup. In response, strong
surface ridging has settled over much of the central and SE CONUS.
The center of this axis extends from the Northern Gulf up to
southern Minnesota. With Florida just east of the center, a NE flow
is dominant this afternoon. There is a strong pressure gradient
(about 8mb from MIA to JAX), which has favors this NE flow to remain
gusty through the day and overnight. As the ridge axis shifts
farther east over the next 24 to 36 hours, the gradient will begin
to relax somewhat, allowing these winds to subside. Until that
happens, however, gusty winds will continue.

The combination of gusty winds and dry air means that fire weather
concerns are elevated. However, with some rain yesterday, the
significant fire potential remains low; and there is somewhat of
a mismatch between where the strongest winds are occurring and
where the lowest RH values are this afternoon. So it is still not
quite the right setup for red flag conditions. Rather, the main
weather impact is for the marine community. Gusty winds favor
continued rough seas into tomorrow.

The other main weather topic for today is the chilly weather.
However, the easterly component is already allowing temperatures
to warm this afternoon. When combined with gusty winds overnight,
it should keep temperatures well above freezing areawide tonight.
Nevertheless, it will still be chilly. Residents and visitors
should dress appropriately.

While most of the weekend looks fairly benign, the pattern doesn`t
remain zonal for very long. Beginning tomorrow, another trough
starts to dig over the central CONUS. This system will push the
ridge axis further east and suppress it`s influence, leading to a
pronounced easterly shift in the winds and thus additional warming.
By Sunday, there could be enough instability and moisture as a weak
warm front lifts north to support a few showers. Fog will also be a
possibility for Monday morning, especially across the Nature Coast.

Quickly on the heels of this system, a stronger system will dig into
the SE, bringing the next change of weather to the region to end
next week. Not unlike today, cooler, drier, and breezier weather
will settle across the region for the latter half of the week.
However, Monday and Tuesday will feature a more unsettled pattern
with more clouds, showers, and thunderstorms for much of the area.
The main exception is SWFL, where most of the energy and moisture
will be farther removed, favoring warmer and drier conditions
than the rest of the area.

Overall, the setup is will be somewhat of a roller coaster over the
next few days. Enjoy the quieter pattern for the next day or so
before things begin to change next week.

.AVIATION...
(00Z TAFS)
Issued at 702 PM EST Fri Nov 28 2025
VFR conditions will prevail at all terminals for the next 24 hours
with SKC to FEW250 tonight...and SCT LCL BKN250 developing
Saturday afternoon.

.MARINE...
Issued at 1245 PM EST Fri Nov 28 2025

Gusty winds will continue through tomorrow, leading to hazardous
marine conditions across coastal waters with seas of up to 9 feet.
As the winds decrease over the weekend, seas will begin to decrease
as well. However, another approaching front early next week will
again lead to a period of gusty winds and elevated seas for
Tuesday and Wednesday, along with showers and thunderstorms.

.FIRE WEATHER...
Issued at 1245 PM EST Fri Nov 28 2025

Despite being a dry and breezy day with critical RH values in the
20s and 30s, the overall significant fire potential is low given
some rain across central and southern sections of the state
yesterday. Farther to the north where the driest air is present,
winds also remain light enough to preclude rapid fire spread. While
borderline and some spots may instantaneous hit criteria,
widespread red flag criteria are not forecast to be met this
afternoon. As the winds veer to the east overnight and tomorrow,
RH values quickly rebound. There will be additional opportunities
for some showers and storms late in the weekend through early next
week. The next potential for elevated fire weather concerns will
be the latter half of next week.
