Synopsis
Dry high pressure will pass across the area today and tonight,
migrating offshore Thursday and Friday. A summertime feel will
return late week and through the weekend and into next week, as
warmth and humidity move into the carolinas, along a with a few
thunderstorms.

Near term through tonight
As of 3 pm Wednesday... Unseasonably cool and dry high pressure
will build in from the northwest this morning. The high passes
north of the area this afternoon then moves off the nc va coast
tonight. There will be an abundance of dry air in the region
today with precipitable water values under an inch this
afternoon and even lower overnight. Along with the dry air there
will be an increase in mid level subsidence. The exit of the 5h
trough in conjunction with gradual development of weak 5h ridge
results in a strong capping inversion around 11k ft. The dry
air and the inversion will prevent any precip and is likely to
keep cloud cover to a minimum. Temperatures will run below
normal with highs in the mid 80s and lows in the low to mid 60s.

Short term Thursday through Friday night
As of 3 am Wednesday... The chief feature of note this period is
increasing moisture and warmth, and the feel of humidity, as
return flow becomes more established. Weak surface convergence
may spawn a few coastal showers Thursday night, but moisture
will deepen more significantly Friday. A weak cool pool aloft in
the flow will sharpen lapse rates over the area Friday. The
pool will carry a vorticity feature providing a bit of upper
support on Friday. The track of this feature appears to favor
convection over NE sc Friday. Low level winds remain weak but a
few tstms can be expected Friday. Despite a warming trend, both
days may end up similar in maximum temperatures, since more
clouds and rain are anticipated Friday compared to Thursday.

Long term Saturday through Tuesday
As of 300 pm Tuesday... Bermuda high pressure will be well
established with the trough of low pressure inland. Temperatures
will be gradually warming and the moisture will be increasing
with dew points in the 70s returning. Precipitable waters over
the weekend increase to 2 inches and this will bring the best
coverage for diurnal thunderstorms with slightly less coverage
early next week.

Aviation 12z Wednesday through Sunday
As of 10z... FullVFR expected this TAF cycle. Reinforced high
pressure will bring NE winds this morning, veering to E during
this afternoon, then light and variable overnight as pressure
fields become flat weak. Isolated light mist possible near the
coastal interior into daybreak but not widespread nor dense.

Extended outlook... Flight restrictions possible in thunderstorms
over NE sc Friday, and area-wide Saturday afternoon.

Marine
Near term through tonight ...

as of 3 am Wednesday... Northerly flow this morning should peak
shortly after daybreak with speeds rising to 10 to 15 kt as
surge of cooler and drier air works its way down the coast.

Winds drop back closer to 10 kt by midday with direction slowly
veering from northeast to east by late afternoon and evening.

Onshore flow overnight will likely dip below 10 kt. Seas around
2 ft are expected.

Short term Thursday through Friday night ...

as of 3 am Wednesday... Broad high pressure offshore whose axis
will remain mostly north of the region will prompt an e-se flow
of 12 kt or less much of this period. A few showers and tstms
will be possible late Thursday night through Friday. Sea heights
2 feet Thursday and 2-3 feet Friday mainly from the SE every 6-8
seconds can be expected. No caution headlines or advisories. A
weak pressure pattern Friday night as the high retreats farther
offshore will result in S winds 10 kt or less.

Long term Saturday through Sunday ...

as of 3 pm Tuesday... Bermuda high pressure will be established
over the waters with winds shift from the south at 10 knots and
shifting to the southwest at 10 to 15 knots. Seas will range
between 2 to 3 feet Saturday and 3 to 4 feet on Sunday,

Ilm watches warnings advisories
Sc... None.

Nc... None.

Marine... None.

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.
