Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles.. Southerly flow around atlantic high pressure will continue through tonight. A weak cold front will approach from the west during Tue and push across the area waters and offshore during Wed. High pressure will follow and build across the area from the north Wed night into Thu. Another cold front will move across the waters on Fri.

658 am edt Mon mar 27 2017
A progressive weather pattern will bring a few opportunities
for rainfall in the form of showers and thunderstorms through
next Monday. The potential for more substantial and widespread
rainfall appears to bookend the weekend at this point, Friday
and again next Monday. Otherwise, temperatures will be near or
above normal with many places reaching into the 80s the first
half of the week.
Near term /through tonight/
As of 600 am Monday... A warm and moist southerly return flow
will continue around high pressure off shore. Some mid cloud
will move across the area this morning, as morning showers pass
by mainly to our n. Cumulus will develop with the heating of the
day. The high will orient itself more SW to NE off the
southeast coast allowing for winds to veer from SE to s-sw on
mon. The column will moisten up as the ridge up the southeast
coast shifts off shore on Mon as a shortwave moves eastward
reaching the ohio valley by Mon night. Therefore the potential
for showers and possibly thunderstorms will increase through
late day and into tonight with mainly elevated instability as we
lose our heating. Therefore, have included slight chc of shwrs
associated with convergence along sea breeze as it pushes inland
but there will be a better chc of shwrs/iso tstms tonight as a
shortwave rides by.
Lows will be in the mid 50s for most locations. Temperatures will
remain above normal with highs well into the 70s to around 80
inland. Temps tonight will be in the mid 50s most places again.
Short term /Tuesday through Wednesday night/
As of 300 am Monday... Weak low pressure across the ohio valley will
move quickly offshore of the mid-atlantic states Tue night, dragging
a cold front across the area and offshore Wed morning. A strong area
of high pressure will begin to build across the area from the N wed
afternoon and night. Moisture return ahead of mid-week system
looks rather feeble given high pressure will be situated across
the gulf of mexico and across the atlantic, to our s. The column
does briefly moisten sufficiently to warrant isolated to
scattered showers and perhaps thunderstorms Tue with the
activity ending Tue night. High pressure and dry weather will
then gradually build in from the N later Wed and Wed night.
Temps will be well above normal this period, lower 80s inland and
lower to mid 70s at the coast due to marine influences. Tue should
be the warmer of the two days. Lows will be in the upper 50s to
around 60 Tue night, dropping to the lower to mid 50s Wed night.
Long term /Thursday through Sunday/
As of 300 am Monday... Strong high pressure centered across
quebec province Thu morning will ridge south across the eastern
carolinas. The ridge will drift offshore during the day Thu and
thu night. Strong low pressure across the midwest Thu night will
move to the northeast and gradually weaken. Its attendant cold
front will move across the area Fri night. Deep moisture will be
tapped ahead of this system, but the best upper level support
will pass by to our n. Still expect a likelihood of showers and
thunderstorms Fri and Fri night. Drier air will gradually build
into the area on Sat as high pressure slowly builds from the nw,
but with cool air aloft, can not rule out an isolated shower or
thunderstorm. Upper ridge late in weekend will move offshore
during Mon and this will allow a very potent southern stream
system to bring a heightened risk of showers and thunderstorms
across the eastern carolinas as it lifts NE from the gulf coast
states into the southern great lakes region and brings a surge
of deep gulf of mexico moisture northward.
High temps will be above normal through the period, lower to mid
70s. Lows will be mainly in the 50s.
Aviation /12z Monday through Friday/
As of 12z...VFR conditions will dominate this period, with perhaps|
a brief period of MVFR in br at kcre 12-13z and the potential
for MVFR br late tonight throughout. Convection through the
valid TAF period will be isolated and mainly inland. At this
time, did not include a shower or thunderstorm and resulting
visibility restrictions in the taf. However, later forecasts
may opt to include mention if timing resolution improves. Did
initialize with vcsh at klbt as showers are passing mainly to
the N of the terminal this morning. Did also include vcsh at
kflo from 18-00z as this terminal has the highest risk for a
shower or thunderstorm, but still the coverage will be isolated.
Extended outlook... Restrictions to ceiling and visibility possible
in scattered afternoon and evening showers/thunderstorms tue.
Numerous showers and thunderstorms fri/fri night will increase
the risk for reduced ceilings and visibility.
Near term /through tonight/...
as of 300 am Monday... A southerly return flow will continue
around atlantic high pressure through tonight. The high will
orient itself more SW to NE off the southeast coast allowing for
winds to veer from SE to s-sw on mon. The gradient will tighten
slightly as low pressure moves from the central mississippi
valley farther east to the ohio valley, but overall expect winds
around 10 kts through most of the period. Could see up to 15 kt
near shore in aftn sea breeze on mon. Seas will basically
remain 2 to 4 ft thru Mon with a slight rise through Mon night
but the greater SW off shore component will leave the slightly
higher seas off the coast.
Short term /Tuesday through Wednesday night/...
as of 300 am Monday... Weak low pressure across the ohio valley
will move quickly offshore of the mid-atlantic states Tue night,
dragging a cold front across the waters and offshore wed
morning. A strong area of high pressure will begin to build
across the waters from the N Wed afternoon and night. The wind
direction will be SW Tue and Tue night, shifting to the NW and n
wed morning and then veering around to the NE later Wed and wed
night. Wind speeds will be 10 to 15 kt Tue and Tue night. A
developing NE surge Wed night will bring wind speeds up to 15 to
20 kt. Seas will be 3 to 5 ft through much of the period.
Long term /Thursday through Saturday/...
as of 300 am Monday... A small craft advisory may be required
for all waters Fri and Fri night.
Strong high pressure centered across quebec province Thu morning
will ridge south across the waters. The ridge will drift offshore
during the day Thu and Thu night. Strong low pressure across the
midwest Thu night will move to the northeast and gradually weaken.
Its attendant cold front will move across the waters Fri night. High
pressure will gradually build across the waters from the NW during
sat. The wind direction will be from the NE Thu morning, veering to
the E Thu afternoon and SE Thu night. S winds Fri will veer to sw
fri night and then shift to W toward Sat morning. Wind speeds will
be 15 to 20 kt Thu and Thu night and may increase to 20 to 25 kt
fri/fri night. Wind speeds on Sat will be 10 to 15 kt. Seas will be
3 to 5 ft Thu and Thu night, building to 4 to 7 ft fri/fri night
before subsiding to 3 to 4 ft Sat afternoon.

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.
