Update
A few changes with this update that include adjusting pops along
the atlantic coast to reflect new hi-res modeling this morning.

Also, the wind across the gulf are no longer forecast to be above
small craft advisory criteria, so that advisory is now cancelled.

The adjustment to pops is fairly minor, mainly just fine tuning
the pop, not really changing the locations where rain may occur.

aviation...

the wind is forecast to become NE this morning and increase to
around 15kts, with a few higher gusts. Shra is moving into the
area already this morning, so, vcsh is in TAF for the entire
period for most east coast terminals. In generalVFR conditions,
other than only brief ifr restrictions possible in and near
showers through the day.

discussion...

synopsis: an unsettled pattern setting up as a front stalls over
the region today and a series of disturbances moves over the
region Tuesday and again late in the week.

Near term (today-tonight): the front now moving through south
florida will stall out later today near the southern tip of the
peninsula. Showers have been forming overnight over the atlantic
waters along and behind the surface boundary, and the front will
continue to be a focus for showers today. As winds veer to more
easterly and the residual boundary begins to retreat northward,
the showers are likely to spread back over south florida from
southeast to northwest this afternoon and tonight.

Short term (Tuesday-Wednesday): as the remnant front continues
moving northward Tuesday, the greatest concentration of showers
will also shift northward into the lake okeechobee palm beach
region and up into central florida. However, with a relatively
moist air mass in place and a shortwave trough approaching from
the gulf, scattered showers will be possible at times farther
south Tuesday. The strengthening wind fields aloft and focused
upward motion ahead of the shortwave trough should be sufficient
for a few scattered thunderstorms Tuesday, particularly northern
sections closer to the front. Wednesday now appears to be a
relatively dry day with the remnant surface boundary north of the
area and lower tropospheric subsidence in the wake of the
departing shortwave trough.

Medium range (Thursday-Friday night): medium range models are
still having some difficulty with a complex mid troposphere
evolution expected. What they agree on is some vorticity dropping
into the gulf Thursday, prompting cyclogenesis by Thursday morning
along the low level shear axis (remnant front). The timing of the
main shortwave trough turning the corner and lifting out is still
tricky, with the GFS now a bit faster than the ecmwf. So the
period from Thursday afternoon through early Friday will have the
highest chance for showers and scattered thunderstorms, but some
rain risk may stretch into late Friday if the slower ecmwf
solution is correct.

Weekend: although there air mass behind the late week storm
system is not particularly cold, steadily drier air should invade
the region, bringing clearing skies Saturday and allowing low
temperatures to fall into the lower 50s northwest to lower 60s
southeast beaches Sunday morning.

Marine...

northerly wind surge behind the front is bringing 20-25 knot winds
to the atlantic and gulf waters early this morning. Winds on the
gulf side will diminish this afternoon as the front washes out,
but the pressure gradient will remain tight over the atlantic
waters through tonight as wind veer around to easterly, so
hazardous boating conditions will continue. The fresh breeze will
be accompanied by significant wave heights of 7 feet or so in the
gulf stream. Conditions improve Tuesday on through the rest of
the week, though scattered thunderstorms will be possible Tuesday
and again on Thursday into Friday.

Beach forecast...

there will be a moderate risk of rip currents at the atlantic
beaches today as onshore winds increase. If winds come around to
easterly and increase faster than currently forecast, a later
upgrade to high risk may become necessary. Regardless, beachgoers
should be aware of the risk of rip currents today.
