.DISCUSSION...
Issued at 1041 PM EDT Tue Jun 25 2024

A couple reverse cloudlines across the Lower and Middle Keys got
excited towards the late afternoon and early evening. In fact we
saw two rounds of convection develop within these bands. The first
band last about 2 to 3 hours and produced just under a half inch
of rain at the Marathon Airport, an isolated thunderstorm, and a
couple of waterspouts. Based on public report and images sent to
us via social media, they developed across the Bay waters north of
Marathon. The second round occurred just prior to sunset and
produced a more robust looking thunderstorm that put out quite a
bit of lightning strikes before eventually dissipating.

For now the radar is quiet with decaying convection moving off
south Florida towards Bimini and the Bahamas. Closer to home there
are several ghost boundaries left over from earlier showers and
storms. It remains to be seen how this will evolve overnight. Some
of the hi-res CAMs show activity reinvigorating overnight as the
flow slows down. While others show any resurgence in showers and
potential thunderstorms staying offshore across the Straits of
Florida. For now, given the uncertainty as to where things may
re-fire, have maintained chance PoPs for the overnight.

.MARINE...
Issued at 1041 PM EDT Tue Jun 25 2024

No watches, warnings, or advisories are in effect for the Florida
Keys coastal waters. A weak ridge axis will extend westward from
the western Atlantic across the Straits of Florida overnight
through Thursday evening, with light to gentle southwest to west
breezes prevailing over the Keys waters. Breezes may become
variable at times during this period. The ridge will shift back
northward late this week into the weekend, allowing gentle east to
southeast breezes to resume.

.AVIATION...
(00Z TAFS)
Issued at 1041 PM EDT Tue Jun 25 2024

All is quiet for both airfields at this time. There is a chance
that additional showers and thunderstorms may develop overnight
however, exact timing and location remains uncertain. As such,
will omit for now and leave for future amendments. Given the light
southwest to west flow expected to continue into Wednesday (6/26)
there the potential for another cloud line to develop within the
vicinity of both terminals.
