Locally heavy rainfall possible along the space and treasure
coasts this morning...

Update
A quasi-stationary boundary over the treasure coast is beginning
to move slowly to the north as a warm front. Isentropic lift, a
result of veering winds above the surface, along with low-level
convergence along the boundary is aiding shower development.

Expect 4- to 6-hours of enhanced rain coverage over the space and
treasure coasts as the boundary lifts north. The combination of
the front and coastal convergence will enhance rainfall rates in
some of the showers, especially closer to the coast. Considerably
drier air over south florida, noted on water vapor imagery, will
lower rain chances from south to north this afternoon especially
over the treasure coast.

Further to the north (interstate 4 corridor), higher rain chances
are expected this afternoon as moisture from the aforementioned
front begins to interact with an incoming shortwave trough over
the eastern gulf of mexico. Enhanced lift on the ascendant side of
the mid upper level trough and from the right entrance region of
an upper jet should generate scattered to numerous showers from
mid to late afternoon, along with some deeper convection
(thunder). Most of the available guidance shows convection over
the eastern gulf dissipating by the time it reaches the coast, so
afternoon rain chances will likely come as a result of surface-
based instability. Widespread cloud cover overhead will limit this
instability, however, so confidence is lower than usual.

Have adjusted grids to account for current radar trends and the
most recent high resolution model guidance.

Aviation
Vfr ceilings between fl035-fl070 spreading north this morning,
with MVFR CIGS vsbys in showers confined mainly to the treasure
coast terminals (kvrb-ksua). Expect these showers, and perhaps a
thunderstorm, to spread north toward kmlb-ktix through early
afternoon. Additional showers and isolated tsra are expected to
develop elsewhere (kdab-klee-ksfb-kmco-kism) from mid to late
afternoon.

Rain chances are forecast to decrease after sunset (23z), however,
a lingering frontal boundary, enhanced moisture, and light winds will
allow areas of fog to develop overnight, especially over interior
aerodromes.

Marine
Today... A warm front will lift north over the waters today,
shifting winds from the east to the southeast and generating
scattered to numerous showers and isolated thunderstorms. Ese
winds 15-20 knots offshore will decrease some into the afternoon
with seas slowly decreasing. Will continue SCA for sebastian to
jupiter offshore segments into the afternoon otherwise scec
conditions expected.

Tonight... A weak boundary across the waters and weakening pressure
pattern will allow winds to lighten and seas to continue to
decrease, ranging from 3-4 ft near shore to around 5 ft offshore
past midnight.
