Discussion
Tonight through this weekend...

not a whole lot has changed from the previous forecast thinking.

There's still a lot of uncertainty with the tropical disturbance,
whose center is actually just off the southeast florida coast at
the moment. While there are a few bands of showers and
thunderstorms pushing southwestward across the gulf coast and
waters, some subsidence on the immediate west side of the center
of the disturbance has been suppressing shower and thunderstorm
development across the east coast today. This system has become
much better organized over the last 24 hours, with the national
hurricane center now giving it a 70% chance of development over
the next 48 hours and 90% chance over 5 days. Although eventual
development is much more likely, there is still considerable
uncertainty with the track of the system, which in turn will
affect when the disturbance is finally able to develop into a
tropical cyclone. Regardless of development, the potential for
periods of heavy rainfall across south florida remains the primary
threat for this system.

Models are still pretty split regarding the track. GFS still
separates the low-level and mid-level circulations, sending the
low-level portion westward across the peninsula. The ECMWF brings
the center briefly onshore the east coast before emerging back
out over the atlantic as it pushes northward. Several other models
lie somewhere in between. Pretty much all solutions carry at
least some threat for heavy rainfall, but the location of this
potential vary widely based on the different solutions. To account
for this uncertainty, the weather prediction center has placed all
of south florida in a marginal risk for excessive rainfall through
tonight. Bands of showers and thunderstorms are expected to
develop across the eastern portion of the disturbance over the
atlantic overnight and into Saturday morning. If the center
remains near the east coast, the heaviest rainfall could remain
just offshore. However, if the center tracks further inland, the
east coast could be set up for a couple rounds of heavy rainfall
as the bands move onshore tonight. If this solution comes to
fruition, some flooding of urban areas will be likely as the east
coast metro areas have already received a surplus of rainfall over
the last month.

Where the system tracks over the next 12 to 24 hours will heavily
influence the setup going into daytime Saturday and even into Sunday,
both in regards to expected coverage of showers and thunderstorms
and antecedent conditions from rainfall tonight and early
Saturday. Deep tropical moisture will remain overhead throughout
the weekend, so heavy rainfall will be possible with any showers
and thunderstorms that are able to develop. However, again the
coverage and location of the heaviest rainfall will greatly depend
on what happens over the next 12 to 24 hours. If the wetter
solution becomes more likely, an upgrade to a marginal risk for
excessive rainfall would be likely and even a flood watch could
be considered.

Early next week...

as the tropical disturbance lifts northward out of the vicinity
of south florida, long range model guidance indicates that there
should be sufficient moisture left in its path over the peninsula.

For this reason, some of the stronger storms that form in the
afternoon each day may bring locally heavy rainfall and isolated
street flooding in poor drainage and low lying areas. Winds will
become southerly to southwesterly throughout south florida which
will help focus the majority of convection that develops over the
interior lake okeechobee region as well as palm beach county.

Mid-late next week...

high pressure begins to build back into south florida, allowing
for the return of a more typical summertime pattern. A frontal
boundary is expected to stall out to the north of south florida
which may act to enhance overall storm coverage. During this time,
winds will become light and generally southerly, allowing for the
formation of both atlantic and gulf sea breezes each afternoon.

Convection should be driven by a combination of sea breeze and
thunderstorm boundary interactions as well as daytime heating.

Storm coverage is expected to be greatest over the lake
okeechobee interior region as well as the gulf coast during this
period.

Marine
Generally southeast to south winds are expected across the area
through the weekend. A tropical disturbance currently centered off
the southeast florida coast will bring periods of showers and
thunderstorms to all waters tonight through the next couple of
days. A more typical climatological pattern is expected starting
out next week. Gusty and erratic winds with locally higher seas
are possible in and around any convection.

Aviation
Scattered showers and isolated thunderstorms have developed across
the region. These showers will continue throughout the afternoon.

There could be periods of MVFR in and around any shower or
thunderstorm. East southeasterly flow will continue this afternoon
around 10 knots. At kapf, winds will shift around to the west
northwest this afternoon. Scattered showers will continue through
the overnight hours especially across the east coast terminals.
