1024 am est Tue feb 20 2018

Synopsis
High pressure will continue off the coast through mid week and
produce a very warm southerly flow across the region. A
weakening cold front will move into the area late week then
dissipate or lift north Friday. Another front will move
through the area Sunday night into early Monday.

Near term through tonight
As of 1015 am Tuesday... The latest METAR observation are still
showing low clouds across the area, but lifting very slowly,
while visibility have improved across the area... Therefore the
dense fog advisory was allowed to expire. Low level clouds is
expected to dissipate throughout the rest of this
morning... Leading to a mix of Sun and clouds. With high pressure
extending into the region and warm moist southerly flow
today... Most of the hi-res models continuing to indicating
isolated to widely scattered showers through this afternoon.

There will be enough afternoon sunshine to help boost high
temperatures to near record levels in the mid to upper 70s
inland and around 70 beaches.

Short term Wednesday through 6 am Wednesday
As of 255 am Tuesday... Ridging at the surface and aloft
continues from the western atlantic tonight with a persistent
warm moist southerly low level flow across eastern nc. Would
expect to see a repeat of low cloud fog development with the
potential for locally dense fog late as winds partially
decouple. Lows will be in the upper 50s.

Long term Wednesday through Monday
As of 250 am tue... Strengthening high pressure offshore will be
the dominant feature through Thursday, supporting temperatures
well above normal. A slow moving cold front will push into the
area Thursday night and early Friday, then wash out or lift back
to the north Friday afternoon. Above normal temps this weekend,
with another front progged to push through the area late this
weekend into early next week. See climate section below for temp
records.

Wednesday through Friday... The high will cont offshore through
wed as upr rdg builds off the coast. Mainly dry thru Wed night
with area in warm sector and little to no forcing, though an
isolated shower will be possible along the coast. Very mild wed
and Thu with highs in the mid 70s lower 80s. Beaches as usual
will be cooler with mainly upper 60s to low 70s. Areas of low
clouds and fog will be possible in the late night early morning
hours. Sea fog will be possible given the warm air temps cold
water temps and SW flow. If areas of sea fog develop continue,
temps along the coast could be several degrees cooler than
currently forecast. A weak cold front is forecast to push
southward into the area late Thu into early fri, then wash out
or lift back to the north Friday afternoon. Still some
uncertainty on the timing of the front, and how far south it
will get. The GFS and NAM continue to trend faster and further
southward than the ec. Isolated showers possible Thu through
fri, and kept small pops, with front in the vicinity but
moisture and forcing look weak with little in the way of
rainfall expected. At this time best chance looks like late thu
into fri, mainly across the northern forecast area. Temp
forecast could be tricky fri, and likely depend on how far south
the boundary gets. Bit cooler fri... Though hgts thicknesses
remain high so mild temps cont with mid 60s lower 70s inland to
lower mid 60s along the coast.

Saturday through Monday... High pressure will continue to extend
over the area from offshore Sat and sun. Isolated showers will
be possible sat, but better chances Sun ahead of the approaching
front. Temps will likely approach records again Sat and sun,
with low level thickness values and SW supporting highs 75-80
degrees inland, and upper 60s to low 70s along the coast. Cooler
behind the front early next week, with highs in the upper 50s
to 60s... And lows falling into the 40s low 50s. The next front
approaches the area Sunday, likely moving through Sun night into
early mon, though the 00z ECMWF is quite a bit slower than the
previous run. The GFS is much more progressive, while the ec is
slower and looks to stall it off the coast early next week.

Scattered showers possible. Increased pops to chance Sunday and
sun night, possibly lingering into Mon depending on the timing
of the frontal passage.

Aviation 15z Tuesday through Saturday
Short term through tonight ...

as of 605 am Tuesday... Widespread lifr ifr conditions in fog
and low ceilings are forecast to persist until early afternoon
then a return toVFR conditions are expected outside a brief,
isolated shower, from mid afternoon through mid evening. Late
tonight conditions again will be favorable for the development
of subVFR conditions in low clouds and fog as moist southerly
flow saturates the low levels beneath the nocturnal inversion.

Long term Wednesday through Saturday ...

as of 250 am tue... Forecast soundings and guidance support low
ceilings and areas of fog developing each night early morning,
with widespread sub-vfr conditions.VFR conditions likely during
the daytime hours after fog stratus dissipate each morning.

Marine
Short term through tonight ...

as of 1015 am Tuesday... Latest buoy obs are showing southerly
flow 5-15 knots and seas 2-4 ft. Based on current web cams will
continue the mention of dense fog along our southern coast,
while the rest of the coastal area visibility have improved.

The atlantic high pressure will continue to produce southerly
flow 10 to 15 kt through tonight with 2 to 4 ft seas. Areas of
dense fog could redevelop again tonight.

Long term Wednesday through Saturday ...

as of 250 am tue... Strengthening high pressure offshore will be
the dominant feature through most of the period. A weak cold
front is forecast to push south into the waters Thursday night
into Friday, before washing out or lifting back to the north
Friday afternoon. Still some uncertainty in how far south the
front will be able to get, and wind directions will depend on
the location of the boundary. S SW winds 5-15 kt expected wed
through thu, with seas 2-4 ft. A brief period of N NE winds
likely Thu night into Friday, before returning to S SW by Friday
evening. Best chances to see the wind shift will be the waters
and sounds, north of hatteras. Increasing SW flow sat, becoming
10-20 kt in the afternoon, with seas possibly building to 5 ft
on the outer central waters.

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.
