AMZ600 Synopsis For Jupiter Inlet To Ocean Reef Fl Out To 60 Nm And For East Cape Sable To Bonita Beach Fl Out To 60 Nm- 1015 Am Edt Sun Aug 25 2019
Synopsis.. A weak area of low pressure will continue moving off to the northeast away from the state early this week, leaving light west-southwest flow across south florida. A small northeasterly swell may arrive for the atlantic waters in the wake of the system mid to late week, bringing seas to 3 to 4 feet. Showers and storms can be expected each day, with the highest coverage moving offshore the atlantic coast in the afternoons.
Gulf stream hazards..None.

Update
The area of low pressure that was over south florida yesterday has
lifted out to the northeast of florida this morning, remaining
disorganized as it drifts away. It continues to be monitored by nhc
for additional development, with a medium chance in the next 48
hours and a high chance in the next five days.

While this system will no longer be directly impacting us, it leaves
behind a well defined trailing low-mid level trough across central
and south florida. Satellite imagery and radar this morning show two
large scale convergence bands associated with this feature; one
aligned from jupiter-lake okeechobee-naples, and the other from
grand bahama-biscayne bay-cape sable.

Showers and storms are already picking up in coverage along the
aforementioned convergence bands late this morning, and expect
activity to continue to increase as we head into midday and peak
heating. The east coast seabreeze is a little uncertain given the
prevailing SW flow, but feel speeds are generally light enough for a
weak boundary to develop just inland from the coast by early
afternoon. This will lead to a pile up of activity along the east
coast mid to late afternoon, especially across palm beach and
broward.

With a moist tropical atmosphere still in place, and the best rain
chances across areas that saw heavy rainfall yesterday, flooding
remains the main threat.

lingering influence from yesterday's weak low pressure system
keeping prevailing SW flow, though very light. East coast
seabreeze uncertain, but expect at least a S to ssw backing 16z-
18z. Ongoing shra likely to expand after 15z, though kapf may see
vcnty activity to start cycle. Shra tsra shift towards east coast
late afternoon, with activity winding down towards sunset. Light
and variable winds overnight.

discussion...

a weak low pressure system, which has been wandering around the
region for the last couple of days, should begin it journey off to
the northeast, along with a 500mb low. As the system exits the
area, models are indicating some weak ridging at 500mb, and a
fairly neutral sfc pattern over south florida. There is still a
bermuda high sitting well to the east north east, which will help
to shift the surface wind to the southwest behind the system.

However, pwats should continue to run over 2 inches for a couple
more days. This with daytime heating should allow for mainly
afternoon showers and thunderstorms to affect the area. The models
are not showing much in the way of a sea breeze today, at least
not for the atlantic coast. With the SW flow, the eastern half of
the cwa, especially around the lake and in broward and palm beach
counties, look to have the best chances for convection today. With
the are still fairly saturated, the flooding of roadways and low
laying areas may still be subject to flooding. The GFS is
indicating that the 500mb temperatures should be around -6c and
cape should be between 1500 and 2000 j kg. Again, conducive for
diurnal convection today. Monday looks to be very similar to
Sunday, with perhaps a somewhat stronger SW flow.

Tuesday, the pattern begins to change a little, with some drier
air trying to work is way in and a weak high trying to build over
the keys. However, the GFS is showing the drier air may have some
trouble totally covering the area. Even so, pwats may drop to
below 2 inches for much of the area for Tuesday and Wednesday.

Cape values also drop to around 1000 j kg over much of the area,
with the exception of the lake region, which is still around 2000
j kg. Wednesday shows a more consistent CAPE value of around 1600
j kg in the afternoon. Tuesday should see a downward trend of
coverage, which GOES into Wednesday, with only a chance of showers
and thunderstorms across the area. The GFS and ECMWF show the low
is slowly moving away from the area, still sitting off the
carolina coast on Wednesday. There is a possibility that the area
could see a dry slot behind this system. Both models are hinting
at this solution, but with slightly different timing, and
coverage. So confidence is fairly low at this time that this will
occur.

By the latter half of the week, a strong 500mb trough will be
traversing southern canada and the great lakes region. This trough
should pick up the low and quickly move it away from the carolina
coast, and bring a cold front as far south as north florida, maybe
even north central florida by Thursday morning. This, of course
would keep south florida in the warm sector and keep convection in
the forecast for the remainder of the week. This will increase
pops for Thursday.

However, the bermuda high should begin to strengthen and
retrograde back towards the area, pushing the front back to the
north on Friday, and allowing a south southeasterly flow to set
up. This would help to lower the pops a tick along the east coast,
but would increase the for the western lake region. Saturday is
still very questionable. The wind pattern does look to turn more
easterly, which would mean lower pops for the atlantic coast, and
an increase for the gulf coast. However, there is a large amount
of uncertainty with the weather for the weekend as a tropical
system may approach the area. The models are currently showing
that the moisture from dorian may move into the area. It is very
uncertain if this will be in the form of an organized system, or a
simple wave of tropical moisture. It is also possible that the
system misses the area entirely. For this reason, have kept pops
right around 50 percent for the weekend. As the system gets closer
and the models get a better handle on its life cycle, the
forecast certainty should increase.

Marine...

showers and thunderstorms continue to be in the forecast through
the week. The wind is forecast to become southwesterly today. By
Tuesday, the wind should shift more westerly for the middle of the
week. Seas are forecast to run 1 to 3 feet, with some possible
building in the gulf stream off palm beach county mid week due to
a weak swell. Even then, the models are only calling for 4 foot
seas for the middle of the week, before dropping back to the 1 to
3 foot range.
