area forecast discussion
national weather service newport morehead city nc
636 pm est Sun feb 17 2019

Synopsis
A boundary to the south will lift back north through the area
as a warm front tonight. A cold front will pass through from the
northwest Monday, then move back as a warm front Tue night
through wed. The front will shift back and forth several times
late in the week, resulting in a continued unsettled weather
pattern.

Near term until 6 am Monday morning
As of 635 pm Sunday... A warm front currently located along the
outer near shore waters early this evening will lift north
across the area as a warm front and should be located north of
the region shortly after midnight. This will cause the flow to
veer from east to south resulting in increasing temps overnight.

Thus overnight lows (in the mid to upper 40s most locations)
will occur this evening before midnight with coastal locations
likely rising into the 60s by dawn. Expecting a lull in the
precipitation this evening, then light rain should develop after
midnight and increase in aerial coverage especially across the
coastal plain and western albemarle sound region with only a
small chance for measurable rain in areas to south and east.

Qpf totals should be quite light, with one-tenth of an inch or
less expected overnight.

Short term 6 am Monday morning through 6 pm Monday
As of 635 pm Sunday... Scattered to perhaps numerous mostly
light rain showers are forecast to occur ahead of an advancing
cold front Monday morning, with all the showers expected to be
over by 18z as the front pushes offshore followed by a northwest
flow of drier air in the afternoon. Highs are forecast to be in
the low to mid 60s aided at first by prefrontal southerly flow
and warm morning temperatures, then downslope flow and afternoon
insolation as skies clear after the cold frontal passage. Once
again, QPF totals are expected to be light with amounts 0.10" or
less expected.

Long term Monday night through Sunday
As of 3 pm Sunday... Mostly unsettled weather expected through
the period, as numerous frontal systems low pressure
areas shortwaves impact the region.

Monday night through Tuesday... High pressure will build in from
the north Monday night into Tuesday, allowing for drier and
cooler air to filter in and provide a break from the rain and
clouds. Temps drop into the 30s Mon night under mo clear skies
and light winds. Tuesday will be seasonably cool with highs
ranging from the low 40s NRN obx to the low 50s south and west.

Tuesday night through Wednesday night... As a deep mid-level
trough lingers in the southwestern united states, a moist sw
upper level flow will be present over the SE conus. A weak
shortwave moving up the coast, combined with coastal
front inverted trough developing off the nc coast and warm front
lifting north will be a focus for isentropically driven rain
tue night through Wednesday. The highest QPF and best rain
support continues to be over our northern counties. 17 12z
ecmwf cmc continues to be a bit wetter on Tue night, with gfs
and NAM drier, and will continue to highlight high chc pops tue
night as confidence not yet high enough to mention likelies.

Better consensus that widespread rain occurs Wed as
aforementioned shortwave and weak low pull north with best
moisture lift over the area.

Thursday through Friday... Tough forecast this period, as
wavering front will be nearby, and continued broad SW flow aloft
will mean rain chances each period. Therefore continue to
mention high chc pops. Thursday highs look to be quite warm with
highs in the 70s, then perhaps cooler on Friday if the front can
sink far enough south, though again with timing of front,
temperature forecast is subject to change.

Saturday through Sunday... Somewhat better chc for rain first
part of the weekend, as next low pressure area shortwave will
swing through the ohio valley and bring lift moisture through
the region. Timing of the system this far out is tough, so will
continue high chc rain in the forecast. Temps look to be quite
warm as area will be in warm sector, with highs in the 60s to
70s.

Aviation 00z Monday through Friday
Short term through Monday ...

as of 635 pm Sunday... Though confidence is high that prevailing
subVFR conditions, mainly in ceilings, will persist into
Monday morning, confidence that a long duration ifr event
tonight through Monday morning as depicted in most of the
aviation guidance is lower. Widespread lifr ifr ceilings
spreading into the coastal plain this evening (kinston as been
below 1k ft since early afternoon) should spread across all of
the TAF sites for a period this evening in advance of a
northward moving warm front passing through the area.

Uncertainty develops after midnight as strengthening southerly
flow develops in the warm sector behind the front which would
tend to result in rising ceilings. Forecast soundings indicate
saturation in the low levels overnight supporting persistent low
clouds but not sure they hold at ifr levels. Areas of light
rain are expected to develop in vicinity of the TAF sites after
midnight and should end by late morning as a cold front moves
through the region.VFR conditions will develop in the afternoon
as drier air moves in behind the cold front. A period of llws
is possible this evening ahead of the warm front.

Long term Mon night through Fri ...

as of 3 pm Sunday... Sub-VFR conditions for most of the week,
except for Monday night and Tuesday as conditions are expected
to beVFR under high pressure and partly cloudy skies.

Marine
Short term tonight and Monday ...

as of 635 pm Sunday... Sca's are in effect for the pamlico sound
and the waters south of oregon inlet. A warm front currently
located along the outer near shore waters early this evening
will lift north across the area as a warm front and should be
located north of the waters after midnight. This will cause the
flow to veer from E 10 to 20 kt to S SW 15 to 25 kt overnight
into Mon morning. SW flow Mon 15 to 25 kt early will shift to
the NW 10 to 20 kt in the afternoon behind a cold front. Seas 2
to 4 ft this evening will build to 4 to 7 ft late tonight and
early Mon over the southern and central waters in advance of the
cold front. Winds and seas will briefly drop below advisory
levels Mon afternoon but will increase again Mon night as
stronger cold advection occurs over the waters.

Long term Mon night through Thu ...

as of 3 pm sun... SCA conditions quickly redevelop Mon night as n
to NE surge of 15-25 kt develop behind cold front Monday night
into Tuesday with seas 3-6 ft. NE winds and seas diminish below
sca later tue, then veer E to S on Wed and strengthen back to
15-25 kt with SCA likely redeveloping. Winds turn swrly by thur
and diminish to 10-20 kt.

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.
