Discussion
Subtropical high pressure continues to slowly build expand over
south florida and this will be the case for the next 2-3 days. Dry
air in the 850-500 mb layer has moved into far southern portions of
south florida from the east and will generally spread north as the
high pressure slowly expands over the peninsula through Tuesday. The
mid upper level trough across north florida which has been nearly
stationary the past few days will still play a role in keeping a
more unstable atmosphere across glades, hendry and palm beach
counties where the more stabilizing influence of the high will not
be as pronounced until Monday or Tuesday when the trough weakens in
response to the expanding high.

Today: a few showers over the gulf stream moving onshore southeast
florida will transition to sea breeze-initiated showers and
thunderstorms, with likely initial development of scattered showers
and a few thunderstorms over the metro southeast florida corridor in
the late morning before moving into the everglades by early
afternoon. The gulf seabreeze will also begin to set off showers and
thunderstorms in the naples area during the midday time frame, with
both sea breezes converging over the middle of the peninsula during
the afternoon and drift generally northward. This should place the
highest coverage of afternoon storms from the central everglades to
the lake okeechobee area, but with light steering flow the
outflow boundaries should propagate back towards both coasts. The
gulf coast is a little more likely to see the additional
development later in the afternoon, but could also approach the
western suburbs of SE florida metro. Drier mid levels will cut
down some on the coverage of showers storms south of tamiami
trail. Warmer mid-level temperatures should keep all but the
strongest storms below strong levels. After convection dissipates
early in the evening, another mainly dry night is expected except
for a few atlantic showers or thunderstorms approaching the se
florida coast in the SE flow.

Monday: similar pattern timing to today, except with drier air in
place over most of the region, coverage of showers and
thunderstorms should be slightly lower. The GFS model does show an
increase in moisture from the northernmost extension of a
tropical wave over cuba, but at this time not expecting major
changes in the coverage of precipitation due to the low amplitude
of this wave as it passes our longitude.

Tuesday: deeper E SE flow becomes established across south florida
as the subtropical ridge axis at the lower levels shifts north of
lake okeechobee. Slightly higher moisture tries to move back into
the area with the deeper easterlies, which should bring coverage of
showers and thunderstorms back to near climatological levels for
late july, greatest over interior and gulf coast in the afternoon
and morning night across the SE florida metro.

Temperatures will trend slightly higher through Tuesday as the high
builds over the area. We should see more mid 90s over the everglades
as well as all the way to the gulf coast communities and western
metro communities of SE florida. Heat index values will also rise to
100-105 most areas today and Monday, peaking to around 105-107 over
interior collier county. Tuesday could be the most oppressive day
with heat index reaching or exceeding 105 over much of south florida
even into the metro areas. Low temperatures will stay near or above
80 east coast metro, with mid to upper 70s elsewhere.

Extended period (Wednesday through next weekend): the subtropical
ridge will hold strong across south florida on Wednesday, then begin
to break down late in the upcoming week into next weekend as a
longwave trough sets up over the eastern united states. At least
until Friday the overall precipitation pattern remains about the
same as the beginning of the forecast period, then by next weekend
the flow may turn back to the S and SW as the eastern u.S. Trough
deepens. This shift in the flow would bring afternoon showers and
thunderstorms to the east coast metro areas, with possibly lesser
coverage as you go towards the gulf coast. Temperatures remain
typically hot for late july but perhaps a degree or two cooler than
the hottest day of Tuesday. The SW flow could increase temperatures
a few degrees for the east coast areas, but at this early stage will
keep temperatures only 1-2 degrees above normal with the potential
for even hotter temperatures if trends hold.

Marine
Rather benign conditions expected through most of the upcoming
week. Southeast winds mainly 10 knots or less, except periods of
winds around 15 knots in the gulf stream off miami beach.

Beach forecast
Aside from a few morning showers isolated thunderstorms, it should
be fairly good beach weather with light winds and low risk of rip
currents. The chance of afternoon thunderstorms increases by
Tuesday at the naples marco island area beaches.
