Aviation
A breezy easterly to northeasterly wind is forecast to persist
through tomorrow evening. Shower activity also is possible through
the, mainly from fll, south. Then, early tomorrow morning, rain
chances begin to increase, and will continue to increase through
the morning hours. The best chances for rain will be generally
south of alligator alley through the afternoon.

Update
No significant updates to the forecast this evening, just a few
tweaks to account for current conditions. The forecast continues
to call for breezy to continue through the weekend, with an
increase for rain tomorrow afternoon, especially over miami dade
county, where 2 to 4 inches are possible.

discussion...

breezy conditions, with passing showers looks to the story for the
weekend. Also, a few thunderstorms will be possible. The models
are showing strong surface high pressure building to the north.

This is causing an increasing pressure gradient over the area,
which is responsible for the breezy conditions across the area.

Also, while not very clear, there does seem to be a moisture
boundary setting up over the area. The GFS is showing higher pwats
setting up from around alligator alley, south. Both the ECMWF and
the GFS are showing the highest potential for precipitation
generally in this area as well. This seems to be the pattern for
the weekend.

However, for Saturday models are showing a weak short wave at
500mb moving across the area. Models are indicating some heavier
showers may be possible on Saturday, especially over miami dade
county. Pops are supporting this as well, with a model blend
coming in at around 70 percent chance of rain tomorrow. Qpf
amounts are coming in in at 2 to 4 inches for this area as well.

This will bring the concern of urban flooding for tomorrow for the
miami metro area.

By Sunday, as the high builds to the north, the chances of
precipitation are slowly nudged southward as well. While there is
still a good chance of rain on Sunday for most of the cwa, the
best chances will be south of tamiami trail. Also, models are
ticking the QPF amounts down quite a bit for Sunday. However, if
the totals on Saturday to come to fruition, this could leave the
area saturated for Sunday, keeping the threat of urban flooding a
concern for the area.

The change to the pattern comes on Monday. This is when jerry
should make it far enough north to begin to interact with the
boundary, and push it southward. This helps to dry out the area,
and bring a drier air mass to the region. Dew points are forecast
to trend downward through most of the week. Along with this
downward trend, some of the low temperatures in the western lake
region are forecast to be in the upper 60s as early as Tuesday
morning. This trend looks to last most of the week, with very
little in the way of pops forecast through the end of the week.

There is a slight chance of some showers for most of the area on
Thursday as a small area of moisture advects across the area.

So in summary, increasing pops for Saturday, with rain and a few
thunderstorms possible for the area through the weekend. The
moisture boundary is pushed south on Monday, drying out the area
for the remainder of the forecast period. A drier and slightly
cooler air mass sets up for most of the week.

Marine...

showers and a few storms will be possible this weekend as high
pressure builds to the north. The high is causing a strong
pressure gradient to continue over the area, keeping the breezy
conditions over the south florida waters through the weekend.

This wind, plus a northeast swell is causing seas to run from 7 to
12 feet in the gulf stream, especially off the palm beach coast.

Models are showing the swell slowly subsiding through the weekend,
but keeping seas above advisory criteria through at least Sunday
evening. There is a small craft advisory in effect for all south
florida waters through the weekend, with the atlantic waters
through Monday morning.

Beach forecast...

rough seas off the palm beach coast are bringing high surf to the
palm beach coast. This may cause beach erosion and possibly cause
waves to crash over jetties and piers. With the surf around 8 to 9
feet, a high surf advisory is in effect through Monday morning.

Also, the east wind, along with rough seas may bring strong rip
currents to all beaches along the atlantic coast. There is a high
risk of rip currents through Monday morning as well.
