Dry high pressure will pass across the area through 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

Near term through tonight
As of 1230 pm Wednesday... A wonderful carolina day in store as
dry high pressure shifts over the region today. The morning
sounding from mhx confirms the dry air with a modified sounding
producing a surface base CAPE of 131 j kg and pw of 0.63. Just
south of the forecast area it is a bit more unstable and
slightly more moisture. So sunny skies and temperatures running
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 18z Wednesday through Monday
As of 18z...VFR conditions are expected through this forecast
period as high pressure and drier air will remain. At the end of
the period few to sct clouds below 4000 ft are possible as
onshore flow begins. Northeast winds are expected to veer to the
east this afternoon with speeds reaching 8 to 10 knots in the
afternoons. Overnight winds will be less than 4 knots except
along the southeast coastal tafs which see winds of 5 to 8

Extended outlook... MVFR and ifr conditions are possible in and
near diurnal convection each day from Friday through Monday.

Near term through tonight ...

as of 1230 pm Wednesday... Northeast winds 10 to 15 knots this
morning over the coastal waters will shift to the east by
afternoon and will slowly fall to around 10 knots later this
afternoon and overnight. Seas are ranging between 2 and 3 feet
and this is expected through the overnight period.

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,

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
