Synopsis
Hot and dry weather will prevail much of the week. Rain chances
and slight cooling are possible next weekend, as the upper ridge
flattens, and allows moisture and a weak trough to approach the
coast.

Near term through Tuesday
As of 930 pm Sunday... A surface trough wind shift will enter
the western CWA after 06z, and make its way to the coast around
dawn, in association with a slight weakness in the mid-level
ridging which is established over the SE conus. A quasi-
stationary frontal boundary will drop into central nc Monday,
however it looks to remain north of the area, leaving conditions
Monday very similar to today. That is, rain chances almost nil,
and temperatures reaching the upper 90s away from the coast.

Lows Monday night generally 70-75.

Short term Tuesday night through Wednesday night
As of 3 pm Sunday... Mid-level ridge lingers over the southeast
during the middle of the week. Some differing opinions as to how far
north the center of the 5h ridge. This has impacts locally as there
will be a series of shortwaves, accompanied by moisture, moving
across the top of the ridge. Favoring a stronger ridge and drier
solution through Wed night. Combination of elongated high off the
coast and strengthening piedmont trough each afternoon will keep
winds west-southwest. Sea breeze will have limited success moving
inland, allowing for highs well above climo. Away from the beach,
highs will be in the mid to upper 90s with some areas reaching 100.

Lows are also expected to run above climo, with most areas in the
low to mid 70s. Rainfall chances remain quite limited. Mid-level
subsidence and dry air along with a lack of strong forcing work to
keep most of the area dry.

Long term Thursday through Sunday
As of 3 pm Sunday... Ridging aloft starts to weaken on Thu before
collapsing on fri. Flat mid-level flow develops late next week,
moving a weak front into the region. Lack of strong mid-level push
will keep the front stalled in the vicinity, likely just west of the
forecast area. Increasing moisture will lead to an increase in
rainfall chances late in the week.

-temperatures above to well above climo continue, highs will trend a
little closer to climo for the weekend.

-rainfall chances increase Thu through Sun with the best chances
over the weekend.

Aviation 06z Monday through Friday
As of 5z...VFR this period. Dry atmosphere and breezes will
prevent widespread fog or stratus into Monday, with SW surface
winds through 13z 3-6 knots, becoming w-wnw 6-10 knots in the
afternoon with occasional gusts to 17 kt in daytime, strong
heating. Shreds of cirrus or convective debris, mainly above 15
kft this TAF cycle, accompanied by scattered cumulus in intense
heating of afternoon, density altitudes will be impacted in the
peak of heating.

Extended outlook... MainlyVFR into next week. Slight chance
MVFR each morning in low stratus fog, or isolated tstms,
beginning mainly Monday night.

Marine
As of 3 pm Sunday... South to southwest winds around 10
kt... Gusting to 15-20 kt at times, will continue through the
evening around high pressure centered off the carolina coast. A
wind shift to west-northwest is expected around or just after
sunrise as a weak surface trough moves off the coast, but
southwest flow will reestablish during the afternoon. A weak
gradient will result in wind speeds 10 kt or less Monday night,
and direction will become variable after midnight. Seas of 2-3
ft this evening will fall settle to around 2 feet throughout by
Monday afternoon.

Elongated surface high off the coast and piedmont trough inland will
maintain southwest flow Tuesday through Friday. Gradient tightens up
each afternoon, especially later in the week as the trough becomes
more defined and starts moving toward the coast. Speeds 10 to 15 kt
tue and Wed will climb into the 15 to 20 kt range Thu and fri. Seas
build from around 2 ft Tue to 3 to 4 ft for Thu and fri. Seas
continue to be made up of mostly a south to southwest wind wave.

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.
