.SHORT TERM...
(Today through Sunday)
Issued at 125 AM EDT Sat Jun 28 2025

As the weakening mid level low meanders over the Southeastern
portion of the country, mid level ridging will sneak in across South
Florida from the east and south today. At the surface, high pressure
will remain centered in the western Atlantic with the ridge axis
extending westward over the region. With weak mid level ridging
overhead today, this will allow for a very light steering flow to
set up across the area. At the surface, a light southeasterly
synoptic wind flow will give way to the sea breezes as the day
progresses. At the same time, South Florida will remain entrenched
in a relatively thick Saharan Air Layer. This feature will help to
continue to advect in a drier air pocket especially between 850mb
and 600mb today. This pocket of drier air is clearly seen on the
latest 00z KMFL sounding and the overall PWAT values for today
especially across the eastern and southern areas will be lower than
what they have been over the past several days. With still enough
lower level moisture in place, convective development will be mainly
sea breeze driven and it will focus over the interior and west coast
this afternoon into the evening hours. Convective initiation may
once again take place a bit later then usual due to the Saharan Dust
in place. Once convection does develop, there will still be enough
cold air aloft, (500mb hovering around -9C), and instability in
place due to peak diurnal heating to support a couple of strong
thunderstorms this afternoon where boundary collisions take place
over Southwest Florida. The strongest storms could contain strong
wind gusts as well as small hail and heavy downpours.

On Sunday, the weather pattern will start to show signs of change
again as weak mid level ridging begins to push out of the region in
response to another TUTT (Tropical Upper Tropospheric Trough)
pushing towards South Florida from the Bahamas. At the surface, high
pressure will continue to remain parked over the western Atlantic as
the surface ridge axis extends westward over the region. This will
keep the light southeasterly synoptic wind flow in place to start
the day before the wind field becomes sea breeze driven later Sunday
morning into Sunday afternoon. With the Saharan Air Layer still
remaining firmly in place, convective development may be held down a
little bit to start across the eastern areas on Sunday, however, as
the TUTT gets closer to the region later in the day, this may help
to enhance convection somewhat especially across interior sections.
With light southeasterly synoptic wind flow in place and enough cold
air aloft combined with modest instability due to peak diurnal
heating, some of the storms may once again become strong in the
afternoon and evening mainly across Southwest Florida. Once again
the strongest storms could contain strong wind gusts, heavy
downpours and small hail.

High temperatures for today and Sunday will remain typical for this
time of year as they will rise into the upper 80s and lower 90s
across most areas. Heat index values of 100 to 105 will be possible
across most areas today due to a bit more in the way of sunshine
coming through, however, some areas across southwest Florida could
see peak heat index values of 105-107 this afternoon.

.LONG TERM...
(Sunday night through Friday)
Issued at 125 AM EDT Sat Jun 28 2025

The TUTT will gradually drift over the region on Monday and then
slowly try to push off to the northwest as it weakens on Tuesday. At
the surface, the ridge axis from high pressure centered in the
western Atlantic will remain parked over the region for Monday,
however, it will slowly start to drift southward on Tuesday. At the
same time the Saharan Air Layer (SAL) will remain intact on Monday,
but it will gradually start to thin out heading into Tuesday. This
will cause the mid level pocket of drier air to erode and deep layer
moisture advection will take place as the mid level steering flow
turns southwesterly on Tuesday. The latest guidance suite shows this
pretty well with PWAT values range between 1.6 and 1.9 inches on
Monday and then they rise to 1.9 to 2.1 inches on Tuesday with the
highest values remaining over Southwest Florida both days. With the
drier air pocket still in place across the mid levels on Monday and
a light southeasterly synoptic wind flow, the highest chances of
showers and thunderstorms will remain over the interior and west
coast on Monday afternoon. On Tuesday the wind flow at the surface
will slowly start to shift more to a south to southeasterly
direction in response to the ridge axis drifting south. With deeper
moisture pushing into the region, this may increase coverage of
showers and thunderstorms during this time frame. While the exact
details still remain uncertain, with this type of wind flow on
Tuesday, this may cause the highest focus of convection to shift
towards the Lake Okeechobee region and portions of the east coast
during this time frame. The potential for a few strong to marginally
severe storms will remain in place with weak mid level troughing
still nearby. High temperatures on Monday and Tuesday will generally
rise into the upper 80s and lower 90s.

During the middle to the end of the week, the remnants of the TUTT
look to gradually get absorbed by larger scale mid level troughing
that will be pushing across the Eastern Seaboard during this time
frame. The uncertainty rises in this portion of the forecast as the
latest global and ensemble guidance suite remains in disagreement
with the evolution of this trough as it tries to amplify Thursday
into Friday. The ECMWF solutions are showing a deeper, more
amplified trough pushing through the region on Thursday and Friday,
while the GFS solutions are showing weaker troughing over the region
with the main trough axis remaining to the north. At the surface,
the ridge axis from the area of high pressure in the Atlantic gets
shunted further to the south as a frontal boundary pushes into the
Gulf Coast states as well as Northern and possibly Central Florida.
This will keep a general south to southwesterly wind flow in place
across South Florida from later on Wednesday through Friday allowing
for plenty of deep layer moisture advection to take place during
this time frame. As said before, while the details remain uncertain,
this could help to enhance shower and thunderstorm activity over the
region during this time frame depending on how deep that mid level
trough amplifies and how far south the frontal boundary actually
makes it. This will continue to be monitored as the week progresses.
Right now, the latest forecast takes a blend of the forecast models
and keeps it close to climatology until the confidence level in the
forecast starts to increase. High temperatures for Wednesday through
Friday will remain near climatological normals as they rise into the
upper 80s and lower 90s.

.AVIATION...
(06Z TAFS)
Issued at 125 AM EDT Sat Jun 28 2025

MVFR cigs will continue at a few East Coast terminals early this
morning, with conditions gradually improving with sunrise. Light
southeasterly winds prevail, with winds at KAPF veering from the
west with the Gulf breeze this afternoon. Scattered showers and
thunderstorms will develop in the early afternoon, first along the
western edges of the East Coast metro, then propagating northward
and inland. Short-fuse amendments could be needed in case of any
impacts to the sites.

.MARINE...
Issued at 125 AM EDT Sat Jun 28 2025

A gentle southeasterly wind flow will remain in place across most of
the local waters through the weekend and into the early portion of
next week. Seas across the Atlantic and Gulf waters will remain at 2
feet or less through the weekend and into early next week. Scattered
showers and thunderstorms will be possible across the local waters
each day. Any thunderstorm can produce brief periods of rough seas
along with gusty and erratic winds.
