620 pm est Sat nov 18 2017

A strong cold front will move through the area late tonight and move
offshore early Sunday. High pressure will be over the area through
most of next week.

Near term until 6 am Sunday morning
As of 620 pm Saturday... A strong cold front just west of the
mountains early this evening will sweep quickly east and arrive
in eastern nc after midnight and move offshore by early Sunday
morning. The models are in excellent agreement that there will
be 2 opportunities for light precipitation during the next 12-15
hours. The first is with a batch of light showers currently
moving into the southern waters. These showers are forecast to
brush the immediate coast this evening and overnight and thus
have added a slight chance pop coast to cover. The second and
better chance will be with a broken to scattered area of showers
ahead and along the cold front which will affect the area
primarily from 8z to 14z Sunday (3 am-9 am). Precipitation
amounts are expected to be light, on the order of 0.10" or less
in most locations. Winds will continue to increase overnight,
especially vicinity of the sounds and coastal areas with a wind
advisory in effect for carteret county and the outer banks. The
combination of increased cloud cover and brisk SW winds will
lead to minimum temperatures on the order of 20 degrees warmer
than last night with lows in the 55-60 degree range.

Short term 6 am Sunday morning through 6 pm Sunday
As of 330 pm Saturday... Patchy showers in association with cold
front will end by mid morning with clearing skies as dewpoints
quickly drop into the 30s by afternoon. Despite decent caa, high
temperatures will still be in the pleasant low mid 60s with W nw
breezes subsiding by mid to late afternoon.

Long term Sunday night through Saturday
As of 230 am sat... High pressure then builds in Monday and
Tuesday. Another front will move off the coast Wednesday
morning. Low pressure will pass by to the southeast thanksgiving
day into Friday.

Monday and Tuesday... High pressure will build in from the west
Monday and then move off the coast on Tuesday. Cold air aloft
will lead to much below normal highs on Monday, but then warmer
southerly flow on Tuesday will lead to milder highs. Highs
Monday will be in the mid 50s, and on Tuesday highs will reach
60-65. Low temps will be in the lower to mid 30s inland both
Monday and Tuesday mornings, with mid to upper 30s further east,
and low to mid 40s along the coast.

Wednesday thru Friday... Another fast-moving front will move off
the coast Wednesday morning. After that, an offshore trough
will develop and move over the gulf stream on Wednesday, and
will bring showers to eastern nc. Have slight chance pops west
of highway 17 and chance east. Low pressure will pass by to the
southeast Thursday and Friday. GFS is much stronger with the
low, while the ECMWF is much weaker. Consensus is favoring the
ecmwf solution at this time. Will carry mostly slight chance
pops Thursday and Friday.

High temps will be in the mid 60s Wednesday, and then the mid
50s Thursday and 55-60 Friday. Low temps Wed will range from
the mid 40s inland to the upper 40s to low 50s along the coast.

Lows Thursday will be around 40 on the coastal plain to 45-50
south coast and obx. Lows Friday morning will be in the mid to
upper 30s coastal plain to mid upper 40s south coast and obx.

Aviation 00z Sunday through Thursday
Short term through Sunday ...

as of 620 pm Saturday... High confidence thatVFR conditions
will dominate most of the TAF period, except for a brief period
when the cold front and associated showers pass through the area
between 08-12z when a 1-2 hour period of MVFR conditions will
be possible. Winds will increase tonight into Sunday with gusts
up to 30 knots and a chance of low level wind shear 35-40 kt to
occur. After the frontal passage, conditions will return back to
vfr with gusty NW winds diminishing late.

Long term Sun night thru Thu ...

as of 230 am sat...VFR conditions forecast through the rest of
the period as high pressure builds back over the area.

Short term tonight and Sunday ...

as of 620 pm Saturday... Expect deteriorating conditions with
increasing winds and building seas tonight into Sunday as the
cold front moves through the waters. No changes to current gale
warning or small craft advisories. Anticipate SW winds ahead of
the front to increase to 25-35 knots on most waters after
midnight, with a few gusts to 40-45 knots early in the morning,
before winds become W wnw and subside by late morning to midday
on Sunday. Seas will rapidly increase from 3-5 feet early this
evening and build to 8-13 feet by late tonight and early Sunday
morning, before diminishing offshore winds help subside the seas
fairly quickly by late in the day Sunday.

Long term Sun night thru Thu ...

as of 230 am sat... Winds Sunday night Monday morning will be
nnw 15-20 kts, subsiding to 10-15 kts in the afternoon. Winds
Tuesday will be light and variable before becoming sse 5-10 kts.

Another front will cross the waters Wednesday morning, with
winds becoming north 10-15 knots.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
