.UPDATE...
Issued at 1205 PM EDT Sun Jul 27 2025

A quiet stretch continues in the world of South Florida weather as
ACARS data from area airports continue to depict an expansive dry
layer above 900mb with the caveat of a mid-level subsidence
inversion courtesy of stout mid-level ridging anchored to our
northwest. While CIMSS`s S.A.L. (Saharan Air Layer) Airmass depicts
the majority of the Saharan Dust plume has pushed off west of our
region into the center of the Gulf, a residual portion of the dust
plume is still passing over South Florida today. This shows up
nicely on 16z RTMA/mesoanalysis that depicts precipitable water
values still in the 1.3 to 1.5 inch range as of the writing of this
update forecast discussion. Looking at GOES-19 visible imagery
across the region reveals streaks of low-capped low level cumulus
originating from the coast/oceanic interface of the east coast and
advecting southwestward over our land areas. With the mixing of dry
air down to the surface over the next several hours, most of our
land areas will once again see sparse cloud cover by mid to late
afternoon with the exception being a pinned gulf breeze along
mainland Monroe and southern Collier counties. Given so much dry air
aloft and a subsidence inversion, rain chances will be limited even
along the pinned mesoscale boundary. Still can`t rule out an
isolated shower or two along the pinned gulf breeze mainly during
the late afternoon into early evening hours. Once again, dry air
will prevent heat indices reaching heat advisory thresholds across
the region this afternoon with a "dry" heat being experienced
compared to our usual high dewpoint, high relative humidity feels-
like temperature bonanza. Regardless, if you will be out and about
for the remainder of today, be sure to remain hydrated and take
frequent breaks in the shade/air condition if you are sensitive to
heat illnesses.

.SHORT TERM...
(Today through Monday)
Issued at 105 AM EDT Sun Jul 27 2025

Surface high pressure over the northern Gulf and upper level high
pressure over the SE US today will continue to gradually shift to
the west today and Monday. This will continue to keep plenty of dry
air across the region with PWAT values running well below normal.
The 00Z MFL sounding showed a PWAT value of only 1.14 inches.
Forecast soundings show gradual improvement to around 1.3-1.4 inches
today and then 1.5-1.7 inches on Monday. Today will be the last day
of Saharan dust influence before conditions begin to improve
starting on Monday. Expecting mainly dry conditions today with just
a slight chance of some late day showers or storms over SW FL along
the Gulf coast sea-breeze. High temps today will be in the low to
mid 90s across the east coast metro, and mid to upper 90s over
inland and SW FL. Despite the well above normal temps, lower than
normal dewpoints in the low 70s this afternoon will prevent heat
indices from reaching advisory criteria for the necessary duration.

As low level moisture starts to increase overnight, some coastal
showers will be possible towards Monday morning, otherwise dry
conditions expected for inland and SW FL. Low temps will range from
the lower 70s over inland South FL to upper 70s closer to the coast.

We`ll start to see a return to a more summer-like pattern on Monday
as moisture continues to slowly increase. While PWAT values will
remain below normal at least through the first part of the day,
expect scattered showers and thunderstorms to develop along the sea-
breezes during the afternoon into early evening. High temps will
remain hot with lower 90s over the east coast metro and mid to upper
90s over inland and SW FL. With dewpoints starting to creep up into
the mid and upper 70s, max heat indices of 105-110 are expected.
Will need to monitor closely over the next day to see if headlines
will be needed.

.LONG TERM...
(Monday night through Saturday)
Issued at 105 AM EDT Sun Jul 27 2025

A weak mid level trough and upper level TUTT will move across the
Caribbean on Tuesday and Wednesday. This will have a peripheral
impact on South FL, mainly continuing to increase PWAT values to
near or slightly above climatological norms. These features will
move off to the west and then upper level high pressure builds into
the western Atlantic for the end of the upcoming week and into the
beginning of next weekend reinforcing the low level E/SE flow and
keeping moisture levels at or slightly above normal. Convection each
day will primarily follow a typical summertime pattern, with PoPs
increasing during the afternoon and early evening hours along the
sea-breezes and favoring inland and SW FL, and coastal showers
possible during the overnight hours each day.

Temperatures through the week and into the beginning of next weekend
will remain above normal with highs in the lower 90s across the east
coast metro, and mid/upper 90s over inland and SW FL. Max heat
indices will linger near advisory criteria each day, especially in
Miami-Dade, Broward, and Collier counties. Low temps each night will
be in the mid to upper 70s, and around 80 near the Atlantic coast.

.AVIATION...
(18Z TAFS)
Issued at 1205 PM EDT Sun Jul 27 2025

VFR and dry conditions expected for the remainder of today. ENE
winds at all east coast terminals will continue over the next
several hours with onshore northwesterly winds expected at KAPF as a
gulf breeze gradually pushes inland. An isolated shower or two
cannot be ruled out near KAPF during the late afternoon and early
evening hours. L/V winds once again after sunset with the potential
of SHRA occurring during the early morning hours of Monday along the
east coast of South Florida.

.MARINE...
Issued at 105 AM EDT Sun Jul 27 2025

Gentle NE flow expected today shifting to an easterly flow on
Monday. Seas in both the Atlantic and Gulf waters will be 2 ft or
less. An isolated thunderstorm is possible today with scattered
storms possible on Monday which may result in locally higher winds
and seas.
