.DISCUSSION...
Issued at 252 PM EDT Mon Jul 1 2024
After the very wet morning across the Florida Keys, the afternoon
has been much quieter. KBYX radar shows virtually all the rain
that it was detecting earlier having dissipated. GOES 16 Visible
satellite imagery shows just some cirrostratus cloud debris
leftover. The cloud cover has kept temperatures in check today
with the Island Chain observing lower 80s with dew points in the
mid 70s. At the surface, the western periphery of the subtropical
ridge extends into the Florida Keys. As a result, marine platforms
around the Keys are observing east to southeast winds near 5 knots
with Island Chain communities observing near 5 mph.

.FORECAST...
CIMSS Vorticity shows the lobe that was responsible for the
earlier rain continues to slip to the southwest moving away from
the area. For tonight, expect the Keys to remain quiet for at
least the next several hours as the air mass over the region has
been stabilized for the time being. It will take some time to
destabilize again but some guidance is indicating more showers
and storms during the wii hours of the morning to daybreak
Tuesday. However, we are not expecting this to be nearly as
widespread as it was this morning. A more normal summer-time
pattern is expected to return starting tonight and continuing
through the week. Therefore, the previous 40% from the earlier
forecast package was maintained.

For the remainder of the forecast package, an upper level ridge is
expected to be the main driver of the pattern. Therefore, expect
the typical summer-time chances for rain as moisture undulations
move through the east to at times southeasterly flow with 30%
through the week and weekend including the 4th of July holiday.
Outside of the rain chances, expect more sunshine to return,
therefore, temperatures will also rebound back to where they
typically are for this time of the year. However, we will be
teetering on the edge of Heat Advisories with highs in the lower
90s and dew points of 77 to 78 degrees. Therefore, there may be a
couple times in the coming days where one of these may be issued.

Lastly, Hurricane Beryl which is currently over the western
Caribbean Sea as of the latest National Hurricane Center (NHC)
Advisory at 2 PM EDT, is expected to continue on its west-
northwest trajectory. The projected path keeps the storm well
south of the Florida Keys with it making its closest approach
sometime Wednesday/Wednesday night. This will be when the
gradient may tighten a bit resulting in a slight uptick in winds.
Therefore, a possible breezy period is anticipated Wednesday
evening.

.MARINE...
Issued at 252 PM EDT Mon Jul 1 2024
There are currently no watches, warnings, or advisories in effect
the Florida Keys coastal waters. From synopsis, high pressure
over the western North Atlantic will maintain gentle to moderate
easterly breezes across the Florida Keys. Hurricane Beryl will
remain south of the Florida Keys as it marches west northwest
through the Caribbean Sea Tuesday through Thursday. Breezes will
freshen Wednesday and Wednesday night as Beryl makes its closest
approach. Please review the Tropical Cyclone Advisories for
additional information on the track and future evolution of Beryl.

.AVIATION...
(18Z TAFS)
Issued at 252 PM EDT Mon Jul 1 2024
Weather conditions will transition to a more normal pattern
through tonight. As a result, shower and thunderstorm potential
will taper off to seasonal norms. Surface winds will be light and
variable to start, becoming a prevailing light southeasterly.
