Discussion
Today: upper level trough is pushing through the eastern us this
morning, driving a surface low that is lifting northeast away from
the coast of the carolinas. Two frontal boundary are trailing
behind this low: the first is little more than a weak surface trough
moving south of lake okeechobee, and the second a stronger one
moving through north florida.

The weaker trough is expected to push through south florida
around daybreak, allowing light northwesterly flow to overspread
the region. Other than the wind shift, little change is expected
with daytime highs comparable to Monday in the low to mid 80s.

Flow will be light enough for the east coast seabreeze to develop,
with scattered showers as it struggles to move inland. A few
storms can't be ruled out, though the instability does not look as
high as yesterday given we're currently in between two upper
level features.

Tonight through Friday: strong vort MAX is expected to drop into the
upper level east trough late this evening, digging the larger trough
across the peninsula Wednesday morning, with a strong upper level
low expected to develop just to our east into Wednesday afternoon.

This feature will be driven by a 90-100kt upper jet, which will also
be digging across the state in the same timeframe.

This will drive surface cyclogenesis just to our east across the nw
bahamas along the second front as it moves into central and south
florida into Wednesday morning. The surface low is expected to
deepen as drifts east, setting up a strong pressure gradient across
the state into georgia and the carolinas Wednesday afternoon through
Friday. The net result will be several days of windy, showery, and
slightly cooler weather across the area.

Wind speeds look strongest on Thursday, when north-northeast flow
below 700mb will be a solid 25-35kts across the region, highest
across the local atlantic where the gradient is the tightest. While
it will be a windy day on Thursday, at the moment the forecast stays
below wind advisory criteria, though the east coast will have to be
re-evaluated closer in.

The deeper moisture pooled along the second front looks to get
wrapped up in the low before it quite reaches south florida, meaning
our better moisture will arrive in the form of wrap-around late
tonight into Wednesday afternoon. Overall chances will generally be
30-50%, generally limited the east coast. Chances will diminish to
isolated Thursday and Friday. Rainfall amounts don't look high, but
given the strong winds, will have to watch if any convergence bands
can set up if flow veers a little more northeasterly, or the front
drifts a little further south. Storm threat looks minimal, and
confined to the local atlantic waters.

Winds diminish as we head into Friday as the low moves further away
and the gradient gradually relaxes. However, still expect a breezy
day across the area.

Next weekend into early next week: pressure gradient will decrease
as storm system continues to move well east into the atlantic and
the high pressure center drifts into the state. With a shortwave
ridge aloft also transiting the region this weekend, expect to see
decreasing moisture and winds across the area. A few showers can't
be ruled out, but overall expect partly cloudy skies and seasonably
warm temps in the low to mid 80s. Overnight lows will range from the
low 60s in the interior to upper 60s along the atlantic coast.

Both the GFS and ECMWF agree on keeping a progressive pattern in
place as we head into next week, but disagree on the timing of the
next system. A model consensus has rain and potentially storm
chances returning early next week as the next front approaches.

Marine The main story remains the development of hazardous
boating conditions across all the local waters starting on Wednesday
and continuing into Friday.

The development of a surface low just to our east will set up a
strong north-northeast pressure gradient across the area, that will
extend into the nearby western atlantic. The result will be winds
increasing to 20-25 knots by Wednesday afternoon, with gusts
to gale force into Thursday morning across the atlantic. Winds
will be a little slower to pick up over the gulf waters, more
Wednesday night, and gales do not look as likely.

The combination of local wind wave and fresh swell moving from
further north will drive seas up to 11-15ft in the gulf stream by
Thursday morning, with 6-7ft in the offshore gulf waters.

A small craft advisory is currently in effect for the local
atlantic, with a gale warning now in effect for the offshore
atlantic waters. Advisories will likely be needed for portions of
the gulf waters and lake okeechobee as well, though the current
timing, Wednesday night, places it a little far out to issue an
advisory at this time.

While winds will diminish late on Friday, hazardous seas are likely
to linger for at least portions of the atlantic in Saturday morning.

Aviation Vfr conditions are expected through the period. Winds
will become light NW this morning. The east coast sea breeze should
push through the east coast terminals, causing winds to become E for
awhile this afternoon. There could be a few showers along the east
coast this afternoon and evening, but chances are too low to include
for now.

Beach forecast Several days of rough surf are expected to end the
week as an area of low pressure is expected to develop just to the
east of the state midweek and slowly drift east. The strong north-
northeast winds around the low will lead to a high risk of rip
currents along the atlantic beaches.

Surf heights may peak around8-10 feet along the palm beaches
Thursday and Friday as the longer period fresh swell reaches the
area, with surf heights 2-4ft for broward and miami-dade counties.

In addition to the likely high and rough surf, there may be beach
erosion and coastal flood impacts, especially at high tide. A
high surf advisory or coastal flood statement may be required for
portions of the atlantic coast during the timeframe if the
forecast holds.
