Synopsis
A slow moving, deepening low pressure system will move across
the southern mid-atlantic states tonight through Tuesday,
bringing widespread rain and gusty winds. The low will move
northeast Wednesday and push a cold front through the area
Wednesday night. Several weak disturbances will affect the area
late Thursday into Saturday.

Near term until 6 am Tuesday morning
As of 10 pm mon... Solid rain shield that was spreading into
southwest counties has broken up. Drier boundary layer air
taking a bit longer to erode. However, rain still expected to
overspread area after midnight so will make no changes to
current zones.

Prev disc... Heavy rain threat will arrive late tonight as
continued vort advection diffluence aloft increases with pw's
steadily rising through AOA 1.5in, especially WRN half of the
fa. Winds will also pick up in strength as southeasterly
gradient steadily increses through the night, and begin time of
wind adv still on track with winds gusting AOA 45 mph by dawn
for downeast carteret through obx zones.

Short term 6 am Tuesday morning through 6 pm Tuesday
As of 330 pm mon... Nasty day, especially first half, expected
on Tuesday with continued strong moisture feed into E nc, with
large scale lift maximized through the morning. This will
produce heavy rain localized flooding threat as a couple inches
may fall in short order for some locations. Strong winds will
peak Tuesday from SW to ne, with winds strongest for the obx in
the afternoon, and diminishing for carteret by early to mid
afternoon. Marginal wind adv criteria for the counties bordering
the sounds, though will hold off on issuance attm. Instability
will be on the rise through the day, but large scale lift will
be shunted northeast with organized showers diminishing by
afternoon. However, area will remain in warm sector all day, and
some redevelopment of showers with isolated thunder expected by
afternoon. May be a threat for a marginally strong to severe
storm, especially western portions of the fa.

Long term Tuesday night through Monday
As of 400 am Monday... Slow moving upper low and associated
surface low will produce ongoing wet and windy period into
Tuesday. Lingering upper trough pattern will then result in
some chance of showers into Saturday, with ridging and drying
expected Saturday night into Sunday.

Tuesday night... Surface low will be moving across just inland of
area with precip tapering off as some dry-slotting moves over
area, along with winds gradually diminishing as tighter pressure
gradient moves N and E of area. Pops will diminish to chance
overnight with low temps from upper 50s to low 60s.

Wednesday through the weekend... Dampening upper trough will
finally lift across area Wednesday with lingering small chance
of showers. Wed night looks dry with brief period of upper
ridging, then low chance pops for showers will exist for thu
into Saturday as series of dampening short waves move through
mean upper trough with associated weak surface features. Rain
will become more scattered and taper off as the sfc low lifts ne
and drier air filters in. Temps will warm well into 70s inland
on wed, then generally low to mid 70s rest of period except for
65-70 outer banks.

Aviation 02z Tuesday through Saturday
Short term through Tuesday morning ...

as of 7 pm mon...VFR conditions early this evening but rain
shield is spreading into the area from the southwest with oaj
reporting light rain. Expect MVFR conditions to develop at the
taf sites 4-6z (midnight-2 am) as rain coverage and intensity
begin to increase. There is strong consensus in the guidance
that after 12z (8 am) ifr conditions will develop as the
heaviest rain area moves across the region. Some improvement to
MVFR is expected after 2 pm as the initial widespread rain area
moves out and yields to a more showery regime with scattered
strong showers and thunderstorms possible. Strong SE winds will
gust to 20 to 30 kt through the period.

Long term Tuesday night through Saturday ...

as of 255 pm Monday... Conditions will improve to mostlyVFR
Wednesday through Friday, but the threat of isolated to
scattered showers will continue each day with a possibility of
brief sub-vfr conditions. Direr conditions are forecast to
develop over the area Sat as high pressure builds in.

Marine
Short term through Tuesday ...

as of 10 pm mon... Deteriorating conditions are expected for the
waters and sounds overnight. Ese winds currently 15-20 kt with
gusts to 25+ kt over the warmer gulf stream waters. Winds
further increase tonight becoming SE 25-35 kts, with gusts to 40
knots. Have added neuse and bay and pamlico rivers to the gale
warning as gradient orientation will be up river.

Winds and seas will peak on Tuesday with SE gradient still
producing 25-35 kt winds with highers gusts south of oregon
inlet and pamlico sound. May need a short period gale warning
for albemarle, alligator, and waters north of oregon inlet
Tuesday afternoon as SE gradient pushes through, but marginal
attm and will let later shifts reevaluate. Seas will peak tue
afternoon in the 10-17 ft range.

Long term Tuesday night through Saturday ...

as of 400 am Monday... Ongoing strong and gusty e-se winds will
continue gradually veer to SE and peak at 30-35 kt mainly off
cape lookout to CAPE hatteras during the day as deepening low
pressure approaches from sw. Winds will become s-sw Wed night
and diminish below 20 kt, shifting to NW and N 10 kt or less wed
night into Thu behind weak cold front. Series of relatively
weak systems will affect area late Thu into Friday and again
Friday night into Saturday with speeds mainly 15 kt or less.

Seas peaking 10-15 kt Tuesday will gradually subside to 6-9 ft
by Wed morning, finally dropping below 6 feet by Thu morning,
and then lingering around 3-4 ft into Saturday.

Tides coastal flooding
As of 330 pm mon... A low pressure system will impact the region
tonight through late Tuesday. Strong SE winds will develop,
resulting in many coastal impacts across eastern nc. Minor
coastal flooding will be possible as early as late tonight but
especially Tuesday, for areas adjacent to the pamlico sound and
rivers, as strong southeast winds develop. Winds are expected to
funnel water up the pamlico river, leading to possible minor
flooding up through the town of washington. Minor coastal
flooding, beach erosion, and overwash will be possible late
tonight through Tuesday night for areas along the immediate
coast. Rough surf, dangerous shore break, and a high rip current
risk are expected along the beaches.

It is not checked for accuracy either by anyone at L-36.com 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.
