.DISCUSSION...
Issued at 1040 PM EDT Wed Jun 26 2024

The reverse cloudline today was well underway this afternoon when
we started the afternoon shift. This cloudline though was not as
enthusiastic as yesterday`s. There were no noticeable lightning
activity today and we did not receive any reports of waterspouts.
So in summary, a more active cloudline in terms of precipitation
but not so with lightning or waterspouts. All of the activity came
to a halt shortly after 7 pm though an outflow boundary from the
southern mainland tried to intrude across the Upper Keys and
surrounding waters. This didn`t last long and barely any effects
were felt.

Winds are a little lighter tonight as we are in between features.
A cold front is marching across the northeast and drapes back to
the southwest into the Lower Mississippi Valley. This along with
an accompanying upper level trough is helping to push a ridge out
across the Atlantic further east. This is leaving us in a
temporarily weakened pressure regime. As a result winds are light
and almost variable across the island chain and surrounding
waters. Given a weaker flow, moisture will find it hard to
coalesce into new showers overnight. The best chances may be off
the Upper Keys where earlier convection has left behind
boundaries and that is if these boundaries can collide with enough
force to generate lift. Therefore, have maintained slight chance
PoPs for the overnight.

.MARINE...
Issued at 1040 PM EDT Wed Jun 26 2024

A weak ridge axis will extend westward from the
western Atlantic across the Straits of Florida overnight through
Thursday morning, 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
Thursday afternoon through Friday, allowing light southeast
breezes to resume. Building high pressure over the western
Atlantic during the weekend will bring gentle to moderate easterly
breezes across the Keys waters.

.AVIATION...
(00Z TAFS)
Issued at 1040 PM EDT Wed Jun 26 2024

Dry, VFR conditions expected for the overnight. Chances are lower
for any showers to redevelop, therefore have omitted any mentions
of VCSH at this time. Given the weak flow in place, another round
of cloud lines are again possible Thursday afternoon.
