...New UPDATE, AVIATION...

.UPDATE...
Issued at 104 PM EDT Tue Aug 12 2025

Morning 12Z MFL sounding and recent ACARS soundings show PWAT values
of 1.6-1.8 inches across South FL, with plenty of mid and upper
level dry air. Thus far, mostly shallow showers have been scattered
across the area. A few thunderstorms are likely this afternoon into
early evening aided by sea-breeze and boundary collisions. While an
isolated stronger storm or two is possible, they should remain below
severe limits today. Highest PoPs will favor interior and SW FL
today. High temps this afternoon will be in the low to mid 90s, with
heat indices over 100 through early evening. No significant changes
made to the rest of the forecast period.

.SHORT TERM...
(Today through Wednesday)
Issued at 207 AM EDT Tue Aug 12 2025

Mid-level ridging and an area of surface high pressure will continue
to build in from the western Atlantic today, while a subtle tropical
wave slinks eastward across the northern Caribbean. The interaction
between these two features could promote moderate southerly to
southeasterly winds near the surface while also injecting some
tropical moisture across South Florida. The wave will remain far
enough away from the area to not provide much dynamical support for
convective development over the region; as such, the sea breezes
will once again provide the main lifting mechanism for showers and
thunderstorms to develop this afternoon. CAM guidance shows activity
being maximized over the interior and southwest portions of South
Florida. Coverage should remain isolated to scattered in nature.

Temperatures today will remain in the low 90s across the East Coast,
but would reach the mid 90s across the southwest and interior early
in the afternoon. Overnight temperatures will also remain balmy,
dropping to the   mid 70s and low 80s. Heat indices will reach the
low 100s and will approach advisory criteria, but confidence
regarding coverage and duration remains poor at this time.

Ridging will become more fully established on Wednesday and moisture
will remain near climatological norms, with sea breeze interactions
once again driving scattered convection in the afternoon.

.LONG TERM...
(Wednesday night through Monday)
Issued at 207 AM EDT Tue Aug 12 2025

Surface high will remain in place across the western Atlantic Ocean
and the Florida peninsula for much of the week, promoting light
easterly-southeasterly flow and seasonal afternoon showers each day.
Activity will be sea breeze driven and mostly clustered over
interior and southwest Florida. Temperatures will reach the low-mid
90s each afternoon and there will be a marginal concern for heat
indices nearing or exceeding advisory values across the whole CWA.

.AVIATION...
(18Z TAFS)
Issued at 104 PM EDT Tue Aug 12 2025

SCT MVFR ceilings through early this evening. Scattered showers
and thunderstorms this afternoon into early evening mainly over
interior and SW FL. SE winds around 10 kts, with a SW breeze at
APF after 20Z. Light and variable winds expected overnight.

&&

.MARINE...
Issued at 207 AM EDT Tue Aug 12 2025

Light to moderate easterly to southeasterly winds continue today.
Gulf breezes will bring a shift to west-southwesterly winds over the
west coast each afternoon. Seas should remain around 1-2 ft, except
around thunderstorms, which could produce brief periods of rough
seas and gusty winds.
