Update
Lows this morning got down into the 40s over most of south
florida, except lower to mid 50s southeastern portions of the
area and mid to upper 30s west of lake okeechobee.

High pressure over the southeastern united states will continue to
move slowly move east into the western atlantic waters through
Thursday. This will allow for the steering flow to become more
easterly and increase to breezy conditions this afternoon into
Thursday. This will allow for an enhance threat of rip currents
along the east coast beaches through Thursday, and the high risk
of rip currents has been expanded to include all of the east coast
beaches through Thursday evening. The weather will also remain
dry over south florida today into tonight.

There is also a small northeast swell of 2 to 4 feet that will
continue to affect the atlantic waters through this evening. This
will keep the seas at 5 to 7 feet in the atlantic waters today.

Therefore, the SCA conditions will continue for the atlantic
waters through this evening.

Rest of the forecast looks good at this time and no other changes
are planned.

sct to brief bkn ceilings 4,000-5,000 feet at east coast sites as
winds become northeast to east and bring atlantic moisture back
into the area. Prevailing bkn ceilings at similar levels after 00z
east coast sites, althoughVFR conditions will continue to
prevail. Gulf coast kapf will have only sct clouds through the
period. Light nw-n wind early, becoming 060-080 degrees at 10-12

discussion...

a chilly morning across south florida so far this morning with the
coolest temps of the week thus far due to clear skies and
radiational cooling. The threat for frost is non- zero for hendry
and especially glades counties, but with temperatures dropping
just a degree or two below 40 and winds not completely calm, the
risk seems low enough to keep out of grids forecast. Otherwise,
this mornings low temps are forecast to drop in the lower 40s
across the lake region, low- mid 40s across the gulf coast, and
upper 40s to low 50s for the east coast.

As high pressure slides eastward into the atlantic today, winds
start veering from the east, consequently commencing the
warming moistening trend. Because of this, blue skies will
gradually fill with clouds and a quick passing shower can't be
ruled out over the atlantic waters .Even so, high temps for
Wednesday will only rise into the low-mid 70s across the region.

By Thursday, the combination between high pressure across the
atlantic and a parent low pressure system lurking across tx ar
will aid in a predominantly southeasterly flow. This will spur
deeper moisture and an increase in showers across the region with
forecast derived pwat values increasing up to 1.00 inches
Thursday.

As the work week comes to an end, so does the drier weather. By
Friday, forecast derived pwats swiftly increase up to 2.00 inches
and rain chances spread across the CWA as the aforementioned low
pressure system and associated cold front traverse across the
southern gulf states. With this in mind, GFS has an increase in
cape values on Friday across much of the area with some areas
exceeding 1100 j kg. The problem here is that both GFS and ecmwf
differ on the exact timing of fropa, so the timing of possible
thunderstorms, etc. Are still a bit iffy. GFS continues to trend
faster than ECMWF with FROPA Saturday morning afternoon whereas
ecmwf is insisting on a Sunday morning fropa. This gap in timing
leads to low forecast confidence beyond Friday and could create
some variability in the weekend forecast as the week continues.

Because of this, pops are again capped at 50 percent for the time
being Friday into Saturday, though grids are favoring GFS moreso
than ecmwf. The strong to severe storm potential with this next
low pressure system is still too far in time to discern right now,
especially with variances in models; however, the forecast
evolution will continue to be monitored through the week in case a
threat emerges.

Into early next week (after fropa), high pressure returns and nw
will winds prevail, allowing for a dry and pleasant conditions,
along with cooler temps.

Marine...

as NE winds of 15-20 kt prevail across the atlantic waters, seas
of 6-8 ft, with occasional 8 ft waves, are possible. Because of
the higher seas, a small craft advisory is valid to 1 pm this
afternoon for the atlantic. Small craft exercise caution should
be followed through the first half of the day Wednesday for the
gulf waters as winds stay within 15-20 kt. Wind speeds will
continue to lower Wednesday and Thursday but could increase to
near advisory levels again for the atlantic waters on Friday.

Increasing moisture will also bring a chance of showers early
Wednesday and then Thursday into Friday for the atlantic. The
next cold front is poised to impact the waters sometime between
late Friday and late Saturday.

Winds and seas will slowly start to improve across the atlantic
and gulf waters towards the end of the weekend.

Beach forecast... In concerns to the atlantic, a high risk of rip
currents will exist today across palm beach county beaches thanks
to an easterly wind component and easterly swells. Outside of
palm beach county beaches, a moderate risk of rip currents will
prevail. As the week progresses, moderate to high risk of rip
currents will be possible across the atlantic coast, especially as
easterly winds continue. &&
