Synopsis
A low pressure system will cross the area tonight. A cold front
will then move through late Tuesday followed by high pressure
Wednesday. Another area of low pressure will affect the area
Thursday into Friday. High pressure will ridge into the region
this weekend.

Near term tonight
As of 7 pm Monday... Latest sfc analysis shows warm front right
along the nc coast with weak low pressure slowly strengthening
on the front over the SE coast. Sfc low will continue to
strengthen and lift NE through eastern nc tonight and early tue
morning. Latest radar imagery shows the main area of light rain
pushing just west and north of the area early this evening.

Could see a brief lull of a few hours before it fills back in.

Late tonight, the warm front will lift north across the area,
while the sfc low moves through after midnight. Strong low level
shear will be present, with low level S SE winds becoming SW at
850 mb at 50+ knots, and MUCAPE values reaching as high as 1500
j kg along the the coast. The combination of instability, shear
and low level helicity is enough to support a few strong to
severe thunderstorms capable of producing locally damaging winds
and or an isolated tornado. SPC continues to outlook the area
in slight to marginal risks of severe weather, with the best
potential along the coast (east of hwy 17). Another concern will
be for the potential for heavy rainfall with 1-2 inches,
locally up to 3 inches possible. This could produce some minor
flooding of low- lying areas. Low temps will be realized early
this evening, increasing overnight with low level warm air
advection.

Short term Tuesday
As of 300 pm Monday... The low pressure system will lift ne
tomorrow, while the cold front moves through late morning.

Models continue to show rain during the morning, and then
redeveloping again as the secondary cold front pushes through.

Temperatures will be warm in the morning with highs in the low
60s inland to the low 70s along the coast, then gradually
decreasing during the day.

Long term Tuesday night through Monday
As of 3 pm mon... Active weather will continue into the second half
of the week. Then, drier and cooler air will move in Friday and
remain into the weekend.

Tuesday night and Wednesday... Some uncertainty remains with the
timing of the cold frontal passage late Tuesday, but it is expected
to make it through the area and offshore by the late night hours.

There is significant disagreement amongst global models with regard
to the amount of WAA moisture advection that will occur ahead of the
front, with some models, including the GFS and nam, trending much
drier. Have opted to trim pops late Tuesday to account for the
uncertainty, through high end chance to low end likely pops remain
Tuesday evening. High pressure will build into the area behind the
front, resulting in a mainly dry and cool day Wednesday. Gusty winds
(especially for coastal areas) will ensue Wednesday
afternoon evening as low pressure developing across the deep south
works with high pressure across the northeast to tighten the
gradient locally.

Thursday... The afore mentioned low will travel up the east coast
Thursday, brining another soggy and breezy day. There remains some
uncertainty in the timing track of the low, but confidence has
increasing in the impacts locally, with rainfall moving in early
Thursday, and Thursday Thursday night being very wet. At least
minor, localized flooding issues are possible given the already wet
soils and the potential for a couple of additional inches of
rainfall.

Friday through Sunday... As low pressure departs the area, it will
drag a cold front off the coast Friday morning, with cooler high
pressure building in behind it. High pressure will continue to ridge
into the area this weekend, however cooler conditions are expected.

High temps Friday will reach the low to upper 60s, with mostly 50s
likely for the weekend. Lows will dip into the 30s inland, but look
to remain above freezing, while remaining in the low to mid 40s
along the coast.

Aviation 23z Monday through Saturday
Short term through Tuesday ...

as of 7 pm Monday... Mixed bag of lifr andVFR conditions across
the TAF sites this evening. Widespread sub-vfr expected through
the period, likely bouncing between categories through 06z.

Light rain becomes heavier and more widespread late tonight and
early Tuesday morning. A line of more organized showers and
isolated thunderstorms is expected to move through the sites
between 07-12z. Strong low level wind shear likely to develop
tonight as 850 mb jet of 50+ knots develops over the area. Pred
ifr conditions likely to develop late tonight and continue into
Tuesday. Ceilings likely to lift to MVFR Tuesday afternoon, but
confidence is low at this time.

Long term Tuesday night through Saturday ...

as of 4 pm mon... The threat for ceiling and visibility
restrictions will persist into Tuesday night as a cold front
works across the area.VFR conditions will return Wednesday, but
be short-lived as ifr conditions are likely as low pressure
impacts the area late Wednesday through Thursday night.VFR
conditions return Friday.

Marine
Short term through Tuesday ...

as of 7 pm mon... Strong winds and dangerous seas developing
tonight and continuing into Tuesday. Latest buoy observations
show E SE winds 15-25 kt with seas 4-7 ft. SE winds this
evening, then becoming southerly and increasing to 25-35 kt in
response to developing low, which should cross the carolinas
late tonight into early Tuesday. Winds peak early Tue morning.

Gale warnings remain in effect for the coastal waters and
pamlico sound, with seas building to as high as 10 feet. Sca
continues for the remaining waters with frequent gusts above 25
knots likely. Winds will slowly diminish through the day
Tuesday, as seas will response as well, but remain above 6 ft.

Long term Tuesday night through Saturday ...

as of 300 pm mon... Winds will remain below SCA criteria, though
6 ft seas may persist across the coastal waters, Tuesday
evening. Winds and seas will increase Wednesday ahead of an
approaching low and remain elevated, with very dangerous boat
conditions expected as low pressure passes near the waters
through at least Thursday night. Winds will approach gale over
the coastal waters Wednesday afternoon and evening, with gusts
near or over 30 kt possible through late Thursday. Conditions
should begin to improve Friday.

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.
