national weather service newport/morehead city nc
749 pm edt Mon mar 27 2017

Synopsis
High pressure will extend over the area from offshore through
tonight. A cold front will approach from the northwest Tuesday
and move through early Wednesday. High pressure will build in
from the north late Wednesday into Thursday. A warm front will
move through from the southwest Friday. A cold front will move
through early Saturday.

Near term /tonight/
As of 745 pm mon... No big changes with early eve update. Only
minor changes to late night with an inc pop trend towards
daybreak but main threat of showers/storms still on tue.

Previous discussion... As of 330 pm Monday... Shortwave ridging
will keep dry conditions in warm sector this evening, then a
more robust shortwave will approach from the west late tonight
with a slight chance of showers over coastal plains by morning.

Sw winds and increasing clouds late will keep min temps in mid
to upper 50s.

Short term /Tuesday/
As of 330 pm Monday... Models remain in good agreement with
shortwave moving across area ahead of cold front, producing
scattered shower/tstm threat through the day. Good instability
(sbcape values around 1500 j/kg and li's around
-5) supports marginal threat of severe mainly mid to late
afternoon. Kept pops in 30-40% range with scattered coverage
expected. Low level thicknesses 1380-1385 meters support max
temps 75-80 inland even with more cloud cover and scattered
precip threat.

Long term /Tuesday night through Monday/
As of 300 pm Monday... Most of the extend will be dry expect for
Friday as widespread rain will affect the region. Temperatures will
be near to above normal temperatures through the period.

Late Tuesday night through Thursday... Showers will taper off late
Tuesday night from west to east. High pressure will build and extend
down from the north... Bringing dry and cooler conditions through
Thursday. Temperatures will be cooler for Wednesday and Thursday.

Wednesday, expect highs in the low/mid 70s inland to low 60s along
the obx, then on Thursday, highs only in the lower 50s over the
northern outer banks to low/mid 60s elsewhere due to the influenced
of a northeasterly flow.

Thursday night through Friday... Deep mid-level trough will dig into
the southern plains and develop a sfc low which will track into the
oh valley/mid-atlantic region Friday. A warm front will lift
north... Allowing deep moisture to advect into the enc. This system
will bring widespread rain with forecast soundings showing pws over
an inch. Rain chances increase late Thursday night/early Friday
morning and continue through late Friday night. Highs will be in the
upper 60s/low 70s inland to 60s along the coast on Friday.

Saturday through Monday... .After the frontal passage and rain has
tapered off on Saturday, high pressure builds in Sunday. The sfc
high will slide off the coast Monday... Allowing a moist return flow
into the region; added a 20-30% pop for Monday. Expect highs in the
low 70s inland to low 60s over the obx.

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

as of 745 pm Monday...VFR conditions expected for most of the
short term, with some MVFR fog possible again tonight. Diurnal
strato CU has since dissipate and only sct/bkn cirrus overnight.

Winds become around 5 knots overnight. Some MVFR fog is
possible from 4-7 am, but with more widespread clouds
approaching overnight this is a low confidence forecast. If the
clouds arrive earlier, fog would be unlikely to develop.

Scattered thunderstorms expected later Tuesday, some storms
could be severe. Only a vcsh mention in terminals, as timing and
placement of storms difficult to discern at this time.

Long term /Tuesday night through Saturday/... .

As of 330 pm Sunday...VFR conditions will persist through most of
the period, expect for Friday. Widespread rain and thunderstorms
Friday will lead to periods of MVFR and possible ifr conditions.

Tuesday. Swell from distant low pressure north of hispaniola
will result in building seas during period, with heights to 6 ft
expected outer portions of southern and central waters
overnight and added southern waters to sca.

Long term /Tuesday night through Saturday/... .

As of 330 pm Sunday... Small craft advisories will be in effect
south of oregon inlet to surf city through Thursday morning.

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.
