.DISCUSSION...
Issued at 1010 AM EDT Sat May 25 2024

Another quiet start for the island chain with what was a gorgeous
sunrise if you manage to catch it this morning. Once again across
the deep Gulf waters, convergence from southeasterlies colliding
with northeasterlies from a land breeze off the mainland, led to
isolated to scattered showers over these waters. Elsewhere, the
radar is free of precipitation echoes. Temperatures across most of
the Keys managed to fall into the lower 80s. The exception (and
two-time winner) was at Big Pine Key where the RAWS measures a low
of 72 degrees. This was thanks to another night of clear skies,
and calm winds, which allowed for excellent radiational cooling to
occur. Since then, temperatures are already rebounding with lower
to mid 80s and dew points in the lower 70s. A broad surface
anticyclone is maintaining a light southerly wind for now.

No changes needed to today`s forecast. This morning`s sounding
continues to show dry air in place along with an inversion
between 850 and 700 mb. This comes as no surprise as a low level
ridge remains anchored over top of the Florida Keys providing
a deep layer of subsidence across the region. The combination of
which will make for nearly nil PoPs. As we go through the day and
the southern mainland and Cuba will heat up, eventually leading to
a diffluent flow across the Keys with light and variable winds.
In addition, a light steering flow from the northwest may allow
for an isolated shower or thunderstorm to drift over the extreme
northern end of the Upper Keys.

.MARINE...
Issued at 1010 AM EDT Sat May 25 2024

Light to gentle breezes generally out of the southeast
to south will continue through this afternoon and tomorrow, and
will periodically become variable in direction due to the light
nature and effects of daytime heating. During the later half of
tomorrow, breezes will clock to a southeasterly to south direction
and modestly freshen as the dominant high pressure shifts its
position.

.AVIATION...
(12Z TAFS)
Issued at 1010 AM EDT Sat May 25 2024

VFR conditions, with light and variable winds, will prevail through
the TAF period at both EYW and MTH.
