.SHORT TERM...
(Rest of today through Sunday)
Issued at 1241 PM EDT Sat Apr 20 2024

Broad mid level ridging that has been in place across South Florida
will gradually continue to break down through the rest of the
weekend. This is in response to a deepening mid level trough digging
southeastward through the Plains and eventually into the Southeast.
At the surface, a broad area of high pressure will continue to push
further east into the Atlantic as a frontal boundary remains draped
across the Gulf Coast States. This frontal boundary will slowly push
southeastward and through Northern Florida tonight into Sunday.
Across South Florida, this will cause the southeasterly wind flow
this afternoon to gradually veer and become more south to
southwesterly on Sunday. With moisture advection continuing to take
place through the rest of the weekend, some isolated shower activity
will be possible across interior sections this afternoon and then
again on Sunday afternoon where the Gulf and Atlantic sea breezes
collide and interact with each other. Due to lack of mid to upper
level support, any shower that develops will be low topped and
relatively short lived. High temperatures will rise into the upper
80s and lower 90s across most areas this afternoon and Sunday.

.LONG TERM...
(Sunday night through Friday)
Issued at 215 AM EDT Sat Apr 20 2024

The aforementioned "cool" front will continue its trek along the
FL peninsula on Monday, potentially reaching South FL by
nightfall. The best dynamic support will most likely remain well
north of the area with the boundary reaching the area basically as
a frontolytic feature, which would support mostly scattered
showers to accompany this boundary. However, some model solutions
do show a subtle mid-level shortwave that could move over the
region during peak daytime heating along with the boundary, which
could support an isolated thunderstorm threat, mainly over the
Lake Okeechobee/Palm Beach county region. Models still show the
decaying front stalling out somewhere over the region and
lingering through mid week, and keeping slight chances of showers
across the region each day.

With increased moisture and warm advection over the area,
temperatures through the period will remain warm across the area,
with highs consistently reaching the mid to upper 80s along the
coasts and the lower 90s across the interior sections.

.AVIATION...
(18Z TAFS)
Issued at 1241 PM EDT Sat Apr 20 2024

VFR conditions will prevail throughout the forecast period.
Southeast winds of 10 to 15 kts this afternoon will gradually
diminish and become light and variable as this evening progresses.
At KAPF, winds will increase and become west southwest this
afternoon as a Gulf breeze develops.

&&

.MARINE...
Issued at 1241 PM EDT Sat Apr 20 2024

A gentle to moderate southeasterly wind flow will continue across
the Atlantic waters for the rest of today. Wind shifts to the west
southwest can be expected over the nearshore Gulf waters this
afternoon. Winds will gradually become south to southwesterly across
all local waters on Sunday. These winds will gradually increase and
become moderate to fresh over the Atlantic waters later on Sunday
afternoon. Wave heights across the Gulf waters will remain at 2 feet
or less through the rest of the weekend. Wave heights over the
Atlantic waters will remain at 2 to 4 feet.

.BEACHES...
Issued at 1241 PM EDT Sat Apr 20 2024

A moderate risk of rip currents will continue through the rest of
the weekend mainly across the Palm Beaches. The risk of rip currents
may increase across all Atlantic Coast beaches towards the middle
portion of next week as onshore flow returns.
