Discussion
Short term (tonight-Saturday)... Satellite and model data depict a
lingering stationary frontal near the florida keys, and keeping a
large swath of enhanced moisture across south florida. Not much
so far in terms of heavy rain, but there are scattered small cells
moving NE to sw, bringing brief periods of moderate rain at
times. This shower activity will continue through Friday, although
a decrease in activity is expected later tonight. A few brief
thunderstorms are also possible.

Expect scattered showers and isolated thunderstorms each day,
with best chances during the afternoon hours. Temperatures
should remain near normal values. Current moderate N NE winds will
gradually veer to the ene starting Friday and through Saturday as
high pressure starts building across the region in the wake of the
fropa.

Long term (Saturday night-Wednesday)... Strong high pressure is
shown by the models building across the western atlantic and the
se states Sunday and Monday, with tighter pressure gradients
resulting in periods breezy winds. These winds will become mainly
easterly early next week.

Global model solutions show another trough deepening over the
eastern half of the us, sending an associated cold front into
florida by Tuesday. Expect an increase in atmospheric moisture
early next week as winds become SE and then S as the cold front
approaches. Models agree in pushing the front into the florida
keys by Wednesday. This front may finally bring a significant
change in temperatures, with cooler conditions and lowering dew
points. In other words, the first days of fall-like weather.

Marine
N NE winds continue during the next few days, with speeds to 20
kts on Friday. Winds will become more easterly later in the
weekend but will remain breezy through the weekend. Seas in the
atlantic waters will be up to 5 to 7 feet for the rest of the week
and into the first part of the weekend.

Beach forecast
Stronger ne-e winds for the upcoming weekend may combine with high
astronomical tides, bringing water levels along the east coast
to near coastal flood criteria. A coastal flood advisory remains
in effect for palm beach county through Saturday. This may need
to be extended southward to include broward and miami- dade later
this week if conditions warrant.

Aviation
Scattered showers and a few thunderstorms will affect the taf
sites today. Coverage of thunderstorms will be few and far over
south florida. Therefore, vcsh has been included at all of the taf
sites but will need to be monitor this afternoon. The CIGS and
vis will remainVFR outside of any shower or thunderstorm where it
could fall down into MVFR. Light winds return tonight withVFR
cigs through Friday. Pressure gradient strengthens increasing ne
to E winds after 15z.
