Increasing winds and building seas will spread southwest over the atlantic and produce hazardous boating conditions from today into the upcoming weekend.

435 am edt Thu mar 23 2017

Northeast wind surge behind frontal boundary will produce
hazardous boating conditions through Friday...

High risk of rip currents and high surf developing at the
atlantic beaches today...

Breezy to windy conditions developing by late morning...

Discussion
Today... Strong high pressure will build toward the mid atlantic into
this afternoon allowing a strong wind surge of ene winds to move
south across the forecast area this morning. Low level convergence
and deepening moisture will allow coverage of showers isolated
lightning storms across the atlantic to move onshore this morning
along the coast and focus southward and into the interior this
afternoon. The area remains on the back side of an 500 mb trough
with cold temps aloft to -15 to -17 c at h5. Short range models
agree on increased low level speed convergence from the atlc
combining with a mid level disturbance and vort lobe dropping down
the peninsula in the NW flow aloft today to produce a chance of
lightning storms initially near the east coast and then into the
interior by mid day with convection tending to favor okeechobee
county and the treasure coast into late afternoon. With the cold
temps aloft could be some stronger cells with gusty winds and small
hail from brevard south into the southern interior. Mostly cloudy
skies are expected much of the day with highest rain chances to 50-
60 percent along the east coast. Highs will be in the lower to mid
70s with windy conditions developing. A lake wind advisory will be
in effect from noon to 8pm for all counties except lake and
okeechobee. Along the coast, a high risk of rip currents is
forecast. The surf will be rough in the morning and building into
the afternoon to high surf criteria. A high surf advisory will go
into effect this afternoon and remain in effect into the night time
hours.

Tonight... High pressure will move slowly off the mid atlantic coast
overnight with breezy/windy onshore flow along the coast and
diminishing winds for the interior. Deeper moisture will transition
to the SRN peninsula and will keep highest pops around 30 percent
for SRN coastal sections. Should see skies become partly cloudy
across the north with a low shower chance near the east coast
overnight. Lows will range from the mid to upper 60s south coast to
the upper 50s interior.

Friday-Saturday... Local weather pattern remains dominated by a
large area of high pressure pressing off the mid atlantic coast,
leaving its trailing ridge axis to our north. Continued maritime
flow through the weekend as gradient slowly relaxes and veers
winds to the east/southeast by Saturday. Model soundings suggest
what little moisture exists (pwats at or below 0.80") will be
squashed underneath a sharp inversion at around 850mb. Will keep
precip chances out of the forecast for most of the area, save for
a low chance over the atlantic waters given the continued stout
onshore flow regime.

Sunday-Wednesday... While several mid/upper level disturbances
will pass to the north of the peninsula through the period, mean
layer ridging appears strong enough to deflect most of their
associated energy away from the area, leaving precipitation
prospects low through the middle of next week. Ridge axis will
settle closer to the central peninsula, allowing the local
pressure gradient and winds to relax. Temps gradually warm
through the period with low/mid 80s becoming quite common by
Monday.

Aviation
Convection will increase in the kdab-kvrb this morning as a back
door front moves into area. The boundary will move south into this
afternoon with gusty ene flow developing for all terminals by late
morning and into the early evening hours. Gusts to around 25 knots
expected with the increasing gradient flow. Scattered convection
will focus south of kism-kmlb by late afternoon as deeper moisture
moves toward the SRN peninsula later today. MainlyVFR CIGS outside
of convection... Though some CIGS to 025-030 psbl with lower marine
stratocu moving onshore from the atlc.

Marine
Today... Ene winds will increase to 20-25 knots today behind a back
door front that will move south through the area. Seas will build to
6-8 ft near shore and 8-11 offshore into the late afternoon. Sca
will be in effect for all marine zones.

Tonight... Pressure gradient will remain tight overnight with east
winds to 20-25 knots. Seas will reach 7-9 ft near shore and up to 9-
11 ft offshore. Small craft remains in effect.

Friday-Saturday... Hazardous boating conditions continue. Tight
pressure gradient will produce a fresh to strong e/ne breeze on
Friday, diminishing to a moderate to fresh e/se breeze on Saturday
as the ridge gradually weakens over the atlantic waters. Seas
6-8ft nearshore and 8-10ft offshore on fri, subsiding to 5-6ft
nearshore and 6-7ft offshore by early Sat aftn.

Sunday-Tuesday... Overall conditions will remain marginal to poor
into early next week with a gentle to moderate e/se breeze, seas
5-7ft on sun, subsiding to 4-6ft north of sebastian inlet and
3-5ft south of the inlet on Monday/Tuesday.

Climate
A record high temperature was tied yesterday at melbourne
international airport at 90 degrees. This equaled the old record
set back in 1955.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
