.SYNOPSIS...
A slow moving coastal low is forecast to drift north and then
northwest towards ENC over the next couple of days. The low is
then forecast to move inland Monday night or Tuesday before
lifting north and weakening mid-week. Late in the week, a cold
front will move through, with another coastal low possibly
developing offshore.
&&
.NEAR TERM /TODAY/...
As of 200 AM Sunday...
Guidance is in good agreement through today, depicting a
coastal low deepening 100 miles, or so, southeast of Cape
Lookout. With the low meandering offshore, the flow over ENC
will remain northeasterly. Breezy northeast winds plus
widespread high clouds should help to keep temperatures below
normal by mid September`s standards.
Regional radar shows a broad area of moderate to heavy rain
offshore, associated with the above-mentioned coastal low. Given
the lack of appreciable movement with the low, it appears the
better moisture will remain offshore through the day today. The
main exception is right along the immediate coast from Cape
Hatteras to Cape Lookout where occasional showers may clip the
area.
&&
.SHORT TERM /TONIGHT/...
As of 200 AM Sunday...
A coastal low is forecast to drift slowly north and west
tonight, edging closer to ENC, but likely still remaining 100
miles, or so, offshore. As the low edges closer, a tightening
pressure gradient should continue to support breezy conditions
along the coast (25-30 mph). An area of deeper moisture is
forecast to edge closer to the coast as well, and this may
support a gradual increase in the chance of showers, especially
along the coast.

Key Messages
- Monitoring the track and strength of a coastal low Monday
   and Tuesday
Early this week, the focus will be on the track and strength of
a coastal low that is forecast to move slowly inland across ENC
Monday or Tuesday. The latest suite of deterministic and
ensemble guidance have generally trended deeper and further
north with the track of the low. Regarding the strength of the
low, guidance is fairly well clustered with a 1005-1010mb low
moving through ENC. However, it`s worth noting that a few
ensemble members suggest the low bottoming out below 1000mb.
Regardless, we continue to expect a period of breezy northeast
winds, especially along the coast where gusts of 25- 35 mph are
expected. The note here is that if the deeper trend continues,
there would be a bump up in the magnitude of winds. Further
inland, winds are not expected to be as breezy. As the low moves
inland, it is expected to weaken, and this should lead to a
decrease in winds across the area.
Based on the latest trends in the track of the low, a plume of
deeper moisture is expected to pivot inland with the low Monday
into Monday night. This should support a band of moderate to
heavy rain on the NW and N side of the track of the low, with
rainfall rates and amounts potentially being enhanced with some
embedded convection late Monday into Monday night. Rainfall
amounts will be highly dependent on the track of the low, with a
larger than normal gradient in amounts possible across the
area. The latest guidance suggests the greatest risk of 1"+ will
be focused along the OBX and portions of the coastal plain east
of HWY 17. This area may shift depending on the track of the
low, but the key message is that there is a good signal for
1-2"+ along and to the N/NW of the track of the low. ENC has had
a very dry start to September, and this should help to limit
the flooding potential. The one exception may be if any area
sees convection train over the same area, with rates overcoming
poor drainage areas. For now, this looks to be on more of an
isolated basis, but we`ll continue to monitor rainfall trends in
guidance.
Once the coastal low weakens, it is forecast to lift north
through the Mid-Atlantic mid-week. This will allow a southerly
flow to return to the Carolinas, which should help temperatures
to warm back up closer to normal. Warming of the residually
moist airmass may allow a chance of scattered showers and
isolated thunderstorms to continue through Thursday.
Late in the week and into next weekend, a cold front is
forecast to move south into the area, with north to northeast
flow returning once again. Yet again, another low may develop
along this boundary then, but guidance isn`t as clear on the
upper level and surface pattern by then.

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
SHORT TERM /through tonight/...
As of 2 AM Sunday...VFR conditions expected through the period.
Scattered to broken high clouds with light northerly winds will
persist through the overnight hours, with these light winds
expected to preclude any fog threat. Some guidance suggests some
lower clouds with bases around 4-5kft may intrude across parts
of the southern OBX and Down East Carteret overnight, but do not
expect any low clouds to make there way to TAF sites. High
clouds persist tomorrow with northeasterly wind gusts again
increasing to 15-20 kts for all TAF sites. Guidance does show
chances for lower clouds to bring MVFR ceilings to the coastline
from MRH up to HSE tomorrow starting late morning and lingering
into the late afternoon, but confidence is high that any MVFR
ceilings will stay east of TAF sites.
LONG TERM /Monday through Thursday/...
As of 2 AM Sunday...Unsettled weather expected to return Monday
with increasing chances for showers (some thunderstorms
possible) beginning early Monday morning as a slow moving area
of low pressure works its way up the coast. Showers and
thunderstorms may bring periods of sub-VFR conditions, but
expect VFR conditions to mostly prevail otherwise. Winds will
remain gusty from the north-northeast, especially along the
coast.
&&
.MARINE...
SHORT TERM /through tonight/...
As of 2 AM Sunday...
Key Messages...
- Rough Marine conditions continue through short term.
Latest obs show NE winds generally 15-20 kt with gusts around
25-30 kt, and seas 5-8 ft. Guidance is in good agreement
through today regarding the development of a coastal low along a
stalled frontal boundary south-southeast of Cape Lookout.
Pressure gradient will remain pinched across the region between
high pressure centered over across the mid-Atlantic and the
coastal low as it meanders offshore today. This strengthening
low will allow winds to strengthen again today to 20-25 knots
(gusts 25-30 kts) across the Pamlico Sound and coastal waters,
with waves building to 6-8 feet (potential for some 9 footers to
creep in south of Oregon inlet). SCAs continue for the coastal
waters and Pamlico sound through the short term period. High-res
guidance is bullish on the increasing winds today and shows SCA
conditions expanding into the remaining inland rivers and
sounds. Currently, confidence is higher in inland rivers/sounds
reaching SCA criteria on Monday. As such, SCAs have been hoisted
for the rivers/sounds beginning Sunday night; however, there is
potential that the start of these new SCAs may need to be
pulled forward to this morning if winds follow high-res
guidance.
LONG TERM /Monday through Thursday/...
As of 2 AM Sunday...
Key Messages:
- Gusty northerly winds continue through Tuesday
- Small Craft Advisory conditions persist into mid-week
Guidance is coming into better agreement regarding the track of
the coastal low forecast to develop off the Southeastern US
coastline today. Most guidance favors the low drifting northward
towards ENC before moving inland and beginning to weaken Monday
night or Tuesday. The pressure gradient will remain pinched
between this coastal low and high pressure to the northwest,
allowing SCA conditions to persist through Tuesday/Tuesday
night. Have expanded SCAs with this forecast package to include
the remaining inland rivers and sounds beginning late Sunday
night. High-res guidance remains on the bullish side for winds
through Monday, indicating a roughly 40-60% chance for gusts to
Gale force for the coastal waters south of Oregon Inlet and the
Pamlico Sound on Monday. Upgrades to Gale Warnings for Monday
may be needed later today depending on how guidance trends
regarding the evolution of the coastal low. Marine conditions
are expected to subside into Wednesday, with winds becoming
southwesterly at 10-15 knots (gusts of 15-20) and waves
subsiding to 3-5 feet.
