.SHORT TERM...
(Rest of today through Wednesday)
Issued at 1241 PM EDT Tue May 7 2024

A rather strong mid level ridge will extend through the Gulf of
Mexico and build towards South Florida as a mid level trough departs
further into the western Atlantic for the rest of today and into
Wednesday. At the surface, high pressure in the western Atlantic
will slowly continue to shift southeastward during this time frame.
The positioning of the surface high will promote southeasterly wind
flow through Wednesday. With just enough lower level moisture in
place, the Atlantic and Gulf sea breezes will provide enough lift to
support isolated shower and thunderstorm development where they
interact with each other over interior Southwest Florida this
afternoon into the early evening. With substantial dry air aloft,
chances for strong thunderstorm development will remain very low.
However, heavy downpours cannot be ruled out with any storm that
does develop. Shower and thunderstorm activity will gradually
diminish later this evening due to loss of diurnal heating. Low
temperatures tonight will generally range from around 70 around the
Lake Okeechobee region to the mid 70s across the east coast metro
areas.

On Wednesday, as mid level ridging continues to build over the
region, some drier air will work its way down into the lower levels.
This will keep chances of showers and thunderstorms very limited and
many areas will remain dry throughout the day. With the ridge
building, a warming trend will begin to take place as high
temperatures soar into the upper 80s across the east coast metro
areas to the lower to mid 90s across interior portions of Southwest
Florida.

.LONG TERM...
(Wednesday night through next Monday)
Issued at 241 PM EDT Tue May 7 2024

The Atlantic ridge of high pressure will shift south as a frontal
boundary associated with a low in northeastern Canada pushes into
the Atlantic. This will lead to the surface ridge axis sitting
over southern Florida from mid to late week period which will
enable a warming trend over several days with widespread 90 degree
temperatures save for sea breeze cooled areas closer to the
coast. Some inland portions of South Florida could see
temperatures reach into the upper 90s, particularly on Thursday
and Friday. Rain chances will remain minimal, though some
convection cannot be ruled out inland. The risk of heat illness
will require monitoring Thursday through Saturday as heat index
values start entering the triple digits. As drier air aloft mixes
to the surface, relative humidity values across interior South
Florida could drop into the upper 20 percent range on Thursday
and Friday which could lead to enhanced fire weather conditions.

Late in the week, the next frontal boundary will move across the
southeastern United States but it will lack the support to clear
South Florida. Increasing moisture will lead to more shower and
thunderstorm activity through the weekend as the front settles over
south central to southern Florida. Temperatures will cool slightly
with the additional cloud cover and rainfall. Saturday could be
more of a transition day where the temperatures could again reach
well into the 90s, particularly over the east coast metro where
the southwesterly to westerly wind flow and urban heat island
could combine to present another day with a heat illness risk
above normal for this time of year.

.AVIATION...
(06Z TAFS)
Issued at 259 AM EDT Wed May 8 2024

VFR conditions will generally prevail throughout the 06Z TAF
period, though some brief passing MVFR CIGs will be possible early
this morning at the east coast terminals. Light and variable
winds will increase out of the SE to around 10kts by late morning.
At KAPF, winds will become SW again in the afternoon as a Gulf
breeze develops.

.MARINE...
Issued at 1241 PM EDT Tue May 7 2024

A gentle to moderate southeasterly wind flow will continue through
the middle of the week across most of the local waters. The
exception to this will be over the Gulf waters where winds may shift
to the southwest in the afternoon as a Gulf breeze develops. Winds
will gradually become south to southwesterly across all local waters
heading towards the end of the week as a frontal boundary approaches
from the north. Seas across the Atlantic waters will remain at 3
feet or less through the middle of the week while seas across the
Gulf waters remain at 2 feet or less.

.BEACHES...
Issued at 1241 PM EDT Tue May 7 2024

The rip current risk will remain elevated throughout the rest of the
week across the Atlantic Coast beaches with the highest chances of
rip currents remaining over the Palm Beaches.
