Synopsis
High pressure will move from the carolinas down to florida
by Friday, allowing temperatures to soar into the 90s. A weak
backdoor front could briefly make it into the area Saturday,
but should return north Saturday night. Unseasonably hot conditions
will continue next week.

Near term through Friday night
As of 330 pm Thursday... A few showers will pass across the northern
tier of local forecast area this afternoon as shortwave passes just
north of the area. Sea breeze was pushing inland with an on shore
flow along the coast and w-sw flow inland. Any clouds associated
with shortwave will dissipate and pass off the coast by Fri morning
leaving plenty of sunshine. A downslope westerly flow will develop
between tail end of a front to the north and high pressure to the
south. This downslope flow will combine with increasing heights from
upper ridge building up from the south to produce temps well into
the 90s, with most places just inland from the beaches running
between 95 and 100. The westerly flow should also slow the sea
breeze progression inland, allowing beach temps to be very warm on
Friday, as well. Overnight lows will be back up a few degrees
tonight as dewpoints creep back up.

Current record highs for Friday may 24:
wilmington 97 in 2011
florence 97 in 1994
n. Myrtle beach 90 in 1949
lumberton 98 in 2011
by Fri night, the tail end of cold front should drop far enough
south with a NE flow developing as high pressure builds down behind
it. After such a warm aftn on fri, expect temps to still be well
into the 70s Fri evening, but as NE flow develops toward morning, we
should shave a few extra degrees off of the dewpoints and temps by
morning.

Short term Saturday through Saturday night
As of 330 pm Thursday... The area will be under a northwest flow aloft
as a potent mid level ridge will reside near the florida
panhandle. At the surface there will be a residual but fading
boundary across the area thus some guidance is generating a
little qpf. Not really surprised to see guidance, especially in
the summer to initially advertise dry conditions only to
transition to some convection albeit isolated. It appears to be
showing up in the extended period as well and is occurring
today. Long story short, I incrementally increased pops but they
still remain below the 15 percent criteria for showing up in
the zones. Highs Saturday will range from the upper 80s along
coastal areas to the middle 90s inland.

Long term Sunday through Thursday
As of 330 pm Thursday... The mid level ridge will slowly drift to
the south through the period but warm temperatures and little
chance of rain will continue. Guidance again shows enough
transition to allow the piedmont trough to become more active
late in the period and have maintained the very slow increase in
pops throughout the period. Highs in the 90s and lows well into
the 70s.

Aviation 00z Friday through Tuesday
As of 0z...VFR continues to prevail with surface high moving to
the south and upper level ridge persisting over the southeast.

Few cirrus clouds overnight before skies clear, with few to
scattered diurnal cumulus possible tomorrow afternoon. Moisture
profiles and elevated winds both unfavorable for fog this taf
period. Current south-southwesterly winds will veer to westerly
by late tomorrow morning, and northwesterly towards end of taf
period, with exception of southwest winds tomorrow afternoon at
cre myr.

Extended outlook... ContinuedVFR conditions are expected through
the weekend as high pressure dominates. There is a slight
chance of MVFR conditions each morning from low stratus and or
fog, and also from isolated afternoon thunderstorms.

Marine
As of 330 pm Thursday...

the tail end of cold front moving by to the north of the waters
and high pressure to the south will kick winds around from s-sw
tonight to W by fri. Sea breeze developing through the aftn
will back winds around slightly to the SW around 10 to 15 kts.

Seas should remain 2 to 3 ft. This front may actually drop into
the waters overnight Fri into early Sat with winds veering
around to the NE to E pushing seas up a bit heading into sat.

There will be a day or two of onshore southeast winds
before a southwest to at times southerly flow prevails through much
of next week. Wind speeds as usual for a summer time pattern will be
10-15 knots. The forecast for significant seas is very stable and
weak with mostly two feet with a few three footers in the spectrum
from time to time.

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.
