Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles.. High pressure will shift farther offshore through today. A strong cold front will approach from the nw tonight and push across the local waters and offshore during Sat. High pressure will follow late Sunday thru the early to mid-week period of next week.

Thunderstorms will become more numerous this evening and overnight
and likely persisting well into Saturday until the unseasonably
strong cold front pushes thru late in the day or early evening.
Given the dynamics ahead of the front, strong to severe
thunderstorms may occur primarily during this evening and
overnight. Drier and cooler air will follow in the wake of this
system Sunday through early next week, with a warming trend to
normal summer heat by the mid to late week period of next week.
Near term through tonight
As of 300 am Friday... A weak area of low pressure will move up
along the coast early this morning, but will weaken further and
get nudged out to sea by mid to upper trough digging down from
the north. The latest models show most of the associated weather
to remain well off shore, but there may be some shwrs tstms
brushing the grand strand and CAPE fear coasts through the
morning hours. Once this moves east, the area should remain in a
lull in pcp for the most part with just some fairly minor sea
breeze convective development as it pushes inland, as well as
some development along piedmont trough farther inland. The flow
will basically be SW veering aloft to a more westerly steering
flow. Therefore, expect periods of sunshine with temps reaching
up around 90 most places.
Expect places west of I 95 to see an increase in convection
between 5 and 8 pm mainly due to localized convection along
piedmont trough and any pre existing boundaries. May see some
stronger storms and possibly some marginally severe with
moderate instability as temps reach around 90 and dewpoint temps
will be in the low to mid 70s. SPC has outlined a marginal risk
for all of south carolina into our local area with a slight
risk reaching down into nc from the north where better dynamics
and greater height falls exist. As shortwave digs south and
pushes a pre frontal trough east overnight, pcp water values
will increase up near 2.3 inches and shear increases within
0-6km. This will increase coverage and potential for damaging
wind gusts in strong to severe thunderstorms overnight.
Overnight lows will be in the mid 70s most places.
Short term Saturday through Sunday night
As of 400 am Friday... Convection will be ongoing at the start of
this period. The worse of the thunderstorm activity having
already occurred during the past evening and overnight but
enough dynamics to support a good chance to likely pops.
Vigorous and potent mid- level close low to drop to the mid-
atlantic states Sat night. As it does so, flow aloft will help
drive the cold front east and south of the area by late
Saturday. The pcpn will end as the cold front moves across the
area. Decent drying occurs in the mid and upper levels Sat night
into Sunday, however plenty of low level moisture to keep
stratocu cloudiness going Sat night into Sunday with a partly to
mostly cloudy sky condition. The closed low opens up Sunday
with the mid-level trof axis progged to swing across the fa late
sun morning thru Sunday evening. The cold pool aloft, excellent
pva and plenty of low level moisture, all will combine to
produce mostly cloudy skies with showers, and the possibility of
thunderstorms. Thus, a low chance pop will be required. With
the freezing level progged to drop as well as wbzs, pea sized
hail is a possibility with the storms that are able to develop
in the vertical, which will be difficult given the dry air
aloft. Will see a downward trend in temps including both maxes
and mins. Thus, for Sunday highs will only range from 80-85 and
sun night lows will see widespread 60s.
Long term Monday through Thursday
As of 300 pm Thursday... Chief headline this period 'early taste
of fall' as both t TD fall below normal for late july Sunday
onward, before a warmup to near normal values by Wednesday or
Thursday. Daybreak Sunday a seasonably robust cold front will be
positioned offshore, while canadian high pressure centered over
the great lakes exerts itself SE into the carolinas. The air
mass change will ring of an early fall feel with dewpoints
dipping deep into the 60s, erasing any muggy feel to the air.
Lingering low level moisture in wake of the front will result in
periods of cloudiness on north winds and many areas could
struggle to crack 80 degrees Sunday. Low-level drying should
bring plenty sunshine Tuesday onward while a warming trend
Aviation 12z Friday through Tuesday
As of 12z...VFR conditions expected mainly late this morning|
thru the afternoon hrs. The exception will be initially this
morning, spotty ifr lifr ceilings across inland terminals that
should scour out by 14z. And, spotty showers along the immediate
coast expected thru 17z, just not enough coverage to warrant
other than vcsh but did include MVFR ceilings. The afternoon
will see occasional CU sc ceilings in the 3k to 5k foot level
but should remain pcpn-less.
Dynamics aloft including the approaching S W trof, and at the
sfc, ie. Pre-frontal trof, and ample moisture with pws
increasing to eventually 2.0+ inches. Will all combine to
produce increasing showers and tstorms that will track from west
to east with storm motions running W at 10 to 20 kt this
evening, and increasing to W at 20 to 30 kt by 12z sat. At this
point have indicated vcts this evening and overnight with prob30
groupings for the actual convection.
Winds generally increasing by midday to s-sw at 5 to 10 kt
inland and becoming S 10 to 15 kt at the coast. Winds will
remain ongoing during tonight with wind directions becoming sw
thruout and speeds around 10 kt with some hier gusts especially
within thunderstorm activity.
Extended outlook... MVFR ifr flight restrictions are likely in
thunderstorms ahead and along cold front sat. Some of the
storms may become strong to severe.VFR expected Sunday thru
Tuesday with Sunday possibly seeing brief MVFR from showers
and or ceilings during the aftn.
Near term through tonight ...
as of 300 am Thursday... Light S to SW winds will increase as
they veer around to the SW to W as gradient tightens ahead of
an approaching cold front through tonight. Winds should back and
pick up slightly in afternoon sea breeze up to 10 to 15 kts but
winds will become 15 to 25 kts late this evening into the
overnight ahead of front. This will push seas up from 2 to 3 ft
today up to 4 to 6 ft by early Saturday. A small craft advisory
has been raised beginning later this evening. A weak area of low
pressure will produce some isolated convection across the
waters this morning but there will be a lull through late this
afternoon before strong to possibly severe thunderstorms move
across the waters overnight.
Short term Saturday through Sunday night ...
as of 400 am Friday... SCA conditions will be ongoing as SW winds
15 to 25 kt with gusts up to 30 kt, veer to the wsw-w during
Saturday. Significant seas will run 4 to 7 ft with the 7 footers
primarily off CAPE fear. The waters from CAPE fear south to
little river inlet will overall experience the hier seas given
the better fetch associated with westerly winds. Wind speeds
will diminish below SCA thresholds for a period of time
associated with the cold front slowly pushing across the local
waters Sat evening. The sfc pg then tightens again with winds
becoming n-ne at 15 to 25 kt which may require a SCA or a scec
at the minimum. Will see a slight drop in the significant seas
to 3 to 5 ft thruout Sun thru Sun night. The primary driver to
the seas will be wind driven waves with periods around 5 to 6
Long term Monday through Tuesday ...
as of 300 pm Thursday... Atypical n-ne winds Sunday through a
good part of Monday in wake of an unseasonably strong cold
frontal passage. Wind direction veers to e-se Monday
afternoon evening and holds from the SE Tuesday. Because of the
unusually strong cell of high pressure pushing in from the nnw,
gusts to 20 kt will become common Sunday and Sunday night,
veering slightly from N to ne, and an 'exercise caution'
headline could be needed Sunday, with 4-5 foot seas outer waters
probable. A few storms early Sunday may be rumbling near the
west wall of the gulf stream and around frying pan shoals.

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.
