1235 pm edt Wed aug 21 2019

Synopsis
High pressure offshore will extend west into eastern north
carolina through mid week as a trough lingers well inland. A
cold front will slowly approach the area late this week and move
through the region this weekend.

Near term until 6 pm this evening
As of 1100 am Wednesday... Short wave evident in mdls and
satellite across central nc is leading to decent cvrg of shra
across the region. Based on this increased init pops thru early mid
aftn over most of the region. Also appears as this short wave
passes E may see less cvrg inland later this aftn.

Prev disc... No major changes to the current forecast as mid and
high level clouds continue over the region. Some sprinkles
earlier along the crystal coast have dissipated. Moist southwest
flow coupled with some weak shortwave energy in the mid-levels
today will lead to a decent coverage of showers and
thunderstorms, especially during the later afternoon and evening
hours. Using a consensus of some of the high-resolution models,
would expect the best chance for convective initiation to again
be the northern and western tier, mainly west of highway 17 and
north of highway 264. Will have 40-50 percent pops in these
areas, tapering to just a slight chance along the southern coast
and southern outer banks. High temperatures today will be
mostly within a degree or two of 90 degrees, except mid 80s
outer banks.

Short term 6 pm this evening through 6 am Thursday
As of 340 am Wednesday... Coverage of showers and storms should
diminish by late evening inland, but given the very moist
airmass, will keep low rain chances near the immediate coast
through the overnight hours. Very warm and humid once again
tonight with lows in the mid to upper 70s.

Long term Thursday through Wednesday
As of 300 am wed... High pressure will extend over the area
Thursday with only scattered thunderstorms expected. A cold
front will approach the area Friday, and then slowly cross
through the forecast area over the weekend, leading to another
period of unsettled weather which may continue into next week.

Thursday and Friday... Lee trough over central nc will help kick
off some showers and thunderstorms Thursday afternoon over the
coastal plain, with the sea breeze possibly sparking some
additional activity closer to the coast. Will keep chance pops
through the evening inland, and then shift pops over the coast
Thursday night as some offshore convection is expected to
develop and may move over coastal areas overnight. A cold front
will slowly move into the area Friday, and will act to trigger
scattered to widespread showers and thunderstorm especially
over the northern sections of the area. Have chance to likely
pops for this region, with some heavy rain and training cells
possible.

High temps both days will reach the low 90s inland, and the mid
to upper 80s along the coast. Low temps remain warm and muggy.

Saturday and Sunday... Better agreement between model guidance
has finally been reached, and it looks like the cold front will
slowly drop through nc on Saturday, passing south of the region
and off the southern nc coast by Saturday night. Have increased
pops to likely at times over the weekend where the best
coverage of precip is anticipated as the front moves south.

Heavy rain and training of cells is possible and flooding may be
an issue, especially considering the copious amounts of rain we
have seen this past week.

On the bright side, cooler temps are expected, with temps
ranging from the low to upper 80s on Saturday... Highest along
the southern coast, where it will stay dry the longest. Then on
Sunday, low 80s expected everywhere as cooler air moves in up in
northern nc, and cloudy conditions limit highs over the southern
tier. Low temps more seasonable, reaching the upper 60s to
low mid 70s.

Monday and Tuesday... Model differences exist for the start of
next week, with the GFS stalling the front and immediately
bringing it back north on Monday leading to more rain chances,
while the ECMWF keeps the front stalled and more less over the
gulf stream, with high pressure building in from the north,
keeping the area mostly dry. Will hedge towards a middle ground
for now, and keep chance pops both Monday and Tuesday. Cooler
temperatures will likely continue with highs only in the low to
mid 80s, and low temps into the 60s and low 70s.

Aviation 18z Wednesday through Monday
Short term through Thursday ...

as of 1235 pm Wednesday...VFR will cont to dominate. Sct
shra tsra will cont thru mid late aftn espcly ERN sites but
limited cvrg with only brief impact to a terminal if at all.

Guidance is showing no fog st again tonight so will go with
persistence fcst with pc to mclr skies. On Thu will see cu
develop thru the morn with some convection poss from mid day on
but again limited cvrg with any impacts very brief.

Long term Thursday night through Sunday ...

as of 315 am wed... MostlyVFR conditions expected through
Friday morning, when scattered to more widespread convection
develops as a cold front moves into the area. The front will
slowly move south through the airspace this weekend, leading to
some periods of extended low visibilities and ceilings with
continued high chances for rain and thunderstorms.

Marine
Short term today and tonight ...

as of 940 am Wednesday..No changes with high pres offshore and
trof to the W producing ssw winds 10 to 20 kts. Will cont to
monitor for poss brief SCA late today into tonight pamlico
sound and portion of coastal wtrs.

Prev disc... Breezy SW winds of 15-20 knots being observed at
daybreak over the pamlico sound and the northern waters, with
10-15 knot winds elsewhere. Seas are 2-3 feet with 10-11 second
swell periods. With an approaching surface trough to the west
and bermuda high pressure lingering offshore, the gradient will
tighten later today and into tonight. Current indication are for
sw winds of 15-20 knots, with a few gusts to 25 knots. Latest
nwps swan model indicates only a small and brief area of 6-foot
seas, so will hold off on any SCA for now and let the dayshift
re- evaluate based on later guidance.

Long term Thursday through Sunday ...

as of 320 am wed... Near small craft conditions will be possible
from Thursday morning through early Saturday morning, with winds
sw 15-20 and occasional wind gusts to 25 kts. Seas will be
mostly 4-5 ft, but some periods of 6 ft seas are possible over
the outer portions of the coastal waters. Will hold off on
an advisory for now.

Winds and seas then weaken slightly as a slow moving cold front
enters the region. Winds will turn to the W at 10-15 kts
Saturday morning, and then as the front slowly sinks south
Saturday, winds will turn to the N NE behind it, but turn to the
s south of the front around 10 kts. Winds will then turn to the
ne on Sunday for all waters and range from 10-15 kts over the
northern waters to 5-10 kts over the southern waters. 3-5 ft
seas will continue through Saturday morning, and then seas
become 2-4 ft through Sunday.

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.
