Synopsis
Low pressure over central north carolina will move northeast today
and push a cold front through the area later tonight. Several weak
disturbances will affect the area from late Thursday into the
weekend.

Near term until 6 pm this evening
As of 310 am wed... Low pressure has now moved into central nc,
with a cold front extending south so the myrtle beach area, and
a warm front extending to the NE up into the southern delmarva
region. A surface trough is pivoting around the low and through
eastern nc early this morning, with showers and thunderstorms
along along it. Most of the convection remains offshore, and
looks to be east of the outer banks now. Will maintain a slight
chance pop for the obx and offshore, but it will be mostly dry
though mid morning. Vertically stacked upper level and surface
low will move across nc and into SE va through the day today,
and will spark some showers after mid morning. By late morning,
and especially in the afternoon, scattered thunderstorms along
with showers are likely, especially north of us 264. No severe
weather is expected, although there could be some small hail.

Current temperatures are mild, mostly in the low to mid 60s. Expect
lows to be close to current readings, in the upper 50s inland
and the low 60s along the coast. Partly cloudy skies later today
will allow temperatures to rise into the mid to upper 70s
inland, with low 70s expected near the coast.

Some patchy fog will also be possible through sunrise, with lots
of low level moisture in the area, and could drop visibilities
to 1-3 miles at times.

Short term 6 pm this evening through 6 am Thursday
As of 320 am wed... Any shower or thunderstorm activity should
begin to weaken by this evening. A dry night is expected
thereafter, with mostly clear skies. The cold front behind the
slow moving low pressure system will finally push through early
tonight, with winds shifting to the nw. Low temps will reach the mid
to upper 50s across eastern nc by morning.

Long term Thursday through Tuesday
As of 330 am Wednesday... Models have come into better agreement
with handling of disturbances for Thu night and Friday and again
Saturday, thus increased forecast confidence with this issuance.

Area will be in-between systems Thursday, then dampening short
wave and associated relatively weak surface reflection will
affect area Thu night into Friday, with main threat of precip
late Thu night. Another short wave trough will move through fri
night into Saturday with main energy remaining north and south
of area. Main eastern u.S. Upper trough will finally move
through north of area late Sunday, followed by ridging surface
and aloft Sun night into Tuesday.

Thursday into Saturday... Thursday looks mainly dry with just
slight chance of showers inland with heating in afternoon.

Dampening short wave will move across SW to NE inland of area
thu night into early Friday with models in better agreement on
weak surface low moving across inland as well, pulling a weak
front through Fri night. Models do hint at possible NW and se
split of precip with this system late Thu night, thus kept pops
at 40% for now. Will have chance pops continuing eastern
sections Fri morning with just slight chance inland, then
flipping to 30% inland 20% coast during afternoon with weak
frontal boundary approaching. With main energy splitting north
and south of area with next shortwave Fri night and Saturday,
models have trended drier that period but still enough support
for slight chance pops. Temps near normal during period with
lows mainly in 50s and highs 65-70 coast and 70-75 inland.

Saturday night through Tuesday... No precip expected through
period. Upper trough passage and high pressure building in from
nw will result in temps cooler than normal Sat night into mon
night, then warming Tuesday with ridging aloft. Lows mainly
45-55 Sat night through Mon night with highs Sunday and Monday
from mid 60s to lower 70s. Highs Tuesday around 70 coast and mid
to upper 70s inland.

Aviation 08z Wednesday through Sunday
Short term through 06z Thursday ...

as of 120 am wed... A mix of MVFR andVFR conditions are
expected for the TAF period. There may be some brief periods of
ifr across the coastal plain overnight, but it should be
predominately MVFR.VFR conditions are present at all TAF sites
currently, with some scattered clouds 1000 to 2000 ft present.

Expect the coverage of this deck to increase overnight, leading
to MVFR ceilings inland, including kpgv and kiso. Closer to the
coast,VFR ceilings should persist through the TAF period. There
could also be some patchy fog developing inland, so have
included in the forecast across the coastal plain.VFR
conditions are expected to return later this morning, and some
scattered showers and thunderstorms are possible later in the
day.

Long term Thursday through Sunday ...

as of 330 am Wednesday...VFR expected most of period. Brief
sub-vfr possible with scattered showers Thu night into Friday
and isolated activity Friday night into Saturday.

Marine
Short term through tonight ...

as of 320 pm wed... Rough seas and strong, but diminishing winds
will continue this morning and through most of today. Small
craft advisories are ongoing for all the coastal waters, and
will continue through Thursday morning afternoon.

Winds are currently ssw 15-20 kts across the coastal waters,
with seas 7-12 ft. Winds and seas will continue to subside
today, although a period of winds SW 20-25 kts is expected late
this afternoon into the evening. Later tonight, winds will shift
to the NW as a cold front moves through the waters, and winds
will become NW 5-15 kts by tomorrow morning. Seas will subside
to 6-10 ft this afternoon, and then to 4-7 ft by early tomorrow
morning.

Long term Thursday through Sunday ...

as of 330 am Wednesday... Weak high pressure will result in light
veering winds for Thursday, the low pressure moving across
inland of area will result in SW winds 15-20 kt late Thu night
into Friday. A weak front will result in another brief wind
shift late Fri night into Saturday, then a stronger front will
move through Saturday night followed by a northerly surge of
15-20 kt winds Sunday.

Lingering elevated seas will finally subside below 6 ft during
the day Thursday, but will build again to near 6 ft outer
southern and central waters late Thu night into Friday with
increasing SW winds. Seas then gradually subsiding to around 3
ft by late Saturday, but building to 4-5 ft again Sunday with
northerly wind surge.

Tides coastal flooding
As of 330 am wed... Lingering long period swell energy will
continue to produce a high rip current risk for all beaches
today along with high surf advisory criteria for the outer
banks.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
