Synopsis
Isolated showers and thunderstorms along the sea breeze this
afternoon will dissipate in the evening. Temperatures in the
mid to upper 90s will be widespread next week with potential for
triple digit temperatures inland. Slight chance of showers and
thunderstorms Monday night, but widespread rainfall is not
expected for much of the week.

Update 9:30 pm through tonight
Tonight: patchy fog possible with slight chances for isolated
showers thunderstorms.

Satellite night fog product shows a steady stream of moisture
this evening pushing into the CAPE fear region tonight, which
brought low clouds for mainly the coastal locations. Weak front
pushing through the region may bring some isolated showers and
ever so slight chance for thunder tonight.

Patches of fog are possible as dew points remain elevated for
the forecast area and low temperatures are expected to drop with
increasing relative humidity values. Otherwise, no major
changes to the forecast tonight.

Near term through Sunday night
As of 330 pm Saturday... Latest surface analysis shows a frontal
boundary near the sc nc border. This front will continue to
dissipate into tonight, but with some associated weak convergence
and decent moisture around 900-700mb, isolated tstms have developed
this aftn. This should continue until around sunset, with coverage
remaining isolated at best. Dry then for tonight with low temps in
the lwr 70s under a partly cloudy sky. Light onshore flow will again
bring the potential for fog and low stratus near the coast. Upper-
level ridge persists over the SE CONUS Sunday, and with westerly sfc
winds, the heat returns for even areas closer to the coast. Expect
highs range from near 90 right at the coast to the upr 90s inland.

Continued mild and dry for Sunday night with lows in the lwr
70s.

Short term Monday through Tuesday night
As of 3 pm Saturday... Mid-level ridge holds strong Mon into Tue as
weak backdoor cold front tries to drop in from the north. Appears
the front will stall just north of the area, but it will lead to
westerly flow at the surface Mon afternoon. This will keep the sea
breeze pinned along the coast, allowing for a return of highs in the
mid to upper 90s for much of the forecast area. Stalled front
lingers north of the area Tue with elongated surface high extending
from the northern gulf of mexico to the western atlantic. Pattern
will maintain westerly flow on Tue at the surface while strong
subsidence continues under the 5h ridge. The result will be another
hot day with temperatures similar to those on mon. Precip chances
appear bleak with subsidence working against upward motion above 8k
ft. Additionally an abundance of mid-level dry air will erode any
cumulus that start to develop. Lows each night will be well above
climo with most areas in the lower 70s.

Long term Wednesday through Saturday
As of 3 pm Saturday... Mid-level ridge over the southeast Wed starts
to weaken on Thu as 5h shortwave passes well northwest of the area.

The flattening ridge retreats south, setting up a progressive mid-
level pattern. Low pressure moving across the mid-atlantic states
and across southern new england drags a cold front into the area
late next week, increasing rainfall chances.

-heat continues Wed and Thu with temperatures 10 to 15 degrees above
normal.

-temperatures moderate slightly Fri and sat, although both highs and
lows will still be 5 to 10 degrees above climo.

-weakening ridge and approaching cold front increase rain
chances Fri and sat.

Aviation 02z Sunday through Thursday
As of 0z... .Tricky overnight conditions in the area due to south-
southeasterly flow moistening low levels at the coast, and increased
relative humidities inland. Ifr stratus currently over cre and myr,
expected to dissipate in a few hours but may hold on longer than
anticipated. Expect MVFR stratus to develop at ilm in the next couple
of hours and look to hold on til morning. Due to ample low level
moisture, forecasting MVFR fog at most terminals, except ilm, but
increased winds may lead to patchy fog and intermittent MVFRVFR
conditions. After daybreakVFR conditions return with clear skies
followed by some diurnal cumulus. Southerly winds overnight will
veer to westerly by tomorrow afternoon, with southwesterly at coastal
sites as sea breeze will remain pinned to coast.

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

Marine
As of 330 pm Saturday... Fairly benign marine conditions for
tonight through Sunday night as a weak front dissipates over the
area and sfc high pressure remains centered offshore. Expect
onshore winds of 10-15 kt tonight, shifting to the SW at a
similar speed Sunday Sunday night ahead of a weak trough
dropping into the area. Seas 2-3 ft. There will be some very
weak sely 7 second swell moving into the area by late Sunday.

Elongated surface high south and east of the waters next week will
maintain southwest to west flow across the waters. Strengthening
piedmont trough each afternoon pinches the gradient, increasing
speeds over the waters. Development of sea breeze will also induce
onshore flow along the coast. Speeds will generally be 10 to 15 kt,
but with potential for solid 15 kt later in the day. Seas 2 to 3 ft,
mostly southerly wind wave, for much of next week will creep up to 3
to 4 later thu.

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.
