Area Forecast Discussion
National Weather Service Newport/Morehead City NC
229 AM EDT Wed Jul 9 2025

.SYNOPSIS...
Typical summertime conditions are expected today. This will be
followed up by a series of upper level systems that will push
across the area bringing unsettled weather through the rest of
the work-week. A backdoor front approaches the area this
weekend, keeping an active pattern in place.

&&

.NEAR TERM /TODAY/...
As of 215 AM Wednesday...

Key Messages

 - Confidence remains low to moderate regarding thunderstorm
   strength and coverage through tonight

Early this morning, a stalled frontal boundary was draped from
SW Virginia east through the Chesapeake Bay region. Convection
ongoing along this boundary is expected to remain focused across
Virginia this morning, as the frontal boundary isn`t expected
to make much progress south. Increasing southerly flow through
the day should then shift this boundary back north, keeping it
well removed from ENC. South of the front, modest low-mid level
convergence should continue to support isolated shower and
thunderstorm development from the Atlantic waters north through
the nearby coastal areas of ENC. Through the day, the low-mid
level convergence is expected to weaken, which will then
relegate any convective potential to the afternoon seabreeze.
The overall lack of convection along the seabreeze yesterday was
likely due to somewhat drier air aloft and residual ridging
aloft. The overall synoptic pattern looks fairly similar for
today. However, ridging shifting a bit further east of the area,
plus the return of 2" PWATs, may allow a bit more convective
potential along the seabreeze compared to yesterday, and the
forecast reflects this. It should be noted, though, that short
term guidance shows a fairly muted seabreeze once again which
makes the convective forecast less certain.

Low-level thicknesses are forecast to decrease a bit compared
to yesterday, and this should allow highs to top out 2-3 degrees
lower than yesterday. Boundary layer dewpoints shouldn`t change
much compared to yesterday, but the slightly lower temperatures
should keep heat indices down some, with a lowered risk of
reaching heat advisory criteria. In light of this, heat
headlines are not anticipated for today.

&&

.SHORT TERM /TONIGHT/...
As of 215 AM Wednesday...

Mid-level ridging shifting offshore will allow upper level
troughing to edge closer to the eastern Carolinas this evening
and tonight, which will support an overall increase in large
scale forcing across the region. The approach of the upper
trough should also help encourage a frontal boundary to edge
closer to the local area as well. The net effect should be an
increased coverage of thunderstorms from central NC north into
central/eastern Virginia. For ENC, the question, then, is
whether or not any of this convection will be able to survive
into the area or not. Short-term guidance is mixed, ranging from
isolated thunderstorms tonight on one side of the spectrum, to
a slow-moving MCS moving east through the area on the other end
of the spectrum. Blended guidance favors the isolated
thunderstorm scenario, and the forecast will reflect that for
now. However, this is something we will continue to assess in
later forecast updates. As the front and upper trough approach
the area tonight, deep layer shear will subsequently increase,
but only to about 15-20kt. This combined with a stabilizing
boundary layer should keep the risk of strong to severe
thunderstorms at a minimum. However, this could be enough to
help maintain some thunderstorm organization through the night
if convection can survive this far east. In the reasonably worst
case scenario, a slow- moving MCS moving through the area would
favor gusty winds, heavy rain, and the potential for minor
flooding.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
As of 0445 Tuesday...A series of shortwave troughs will push
across the region mid to late week continuing to bring an
unsettled pattern across the region. With high PW values, the
greatest threat from the storms will be heavy rainfall. WPC
currently has marginal EROs for Days 2-4 for at least portions
of the forecast area. At this time, instability and shear
parameters do not look overly impressive for severe storms to
develop but could see a few storms producing strong wind gusts.
Temps expected to be near or a couple of degrees below climo.

This weekend, a backdoor front slowly sags down the MidAtlantic
coast, approaching the area but currently forecast to remain
near the NC/VA border.

.AVIATION /07Z WEDNESDAY THROUGH SUNDAY/...
SHORT TERM /through 06z Thursday/...
As of 215 AM Wednesday...

Key Messages

 - MVFR/IFR conditions possible through early Wednesday morning

 - Confidence remains low regarding the TSRA potential through
   Wednesday night

Satellite imagery and surface observations show scattered areas
of low CIGs across portions of ENC at this time. Some expansion
of the low CIGs is possible through early Wednesday morning,
and amendments may be needed if confidence increases at any TAF
site. For now, I opted to continue running with VFR TAFs through
the night due to recent trends in satellite and surface obs.
Any low CIGs that develop should mix out by 14-15z Wednesday.
Like yesterday, it looks like we`ll have at least one more day
of limited TSRA potential along the seabreeze. However, slightly
better lift and increased moisture may allow a bump up in the
risk of TSRA today. In light of this, I`ve kept the PROB30
mention in for all TAF sites, but it should be noted that
confidence is low regarding the TSRA potential. While I kept the
PROB30 groups in, I shortened the time window of TSRA potential
as a way to reflect the lowered confidence. By Wednesday
evening, TSRA developing across central NC may make a run at
ENC, but confidence remains low to moderate, and the TAFs will
not reflect this potential yet.

LONG TERM /Thursday through Sunday/...
As of 0430 Tuesday...A series of mid-level systems will push
across the region mid to late week continuing to bring the
threat of showers and storms with reduced flight cats. Late
night and early morning fog and stratus will also be possible
most mornings for areas that see meaningful rainfall.

&&

.MARINE...
SHORT TERM /through tonight/...
As of 8 PM Tuesday...

Improving conditions early this morning with winds becoming SW
15-20 kts, and then winds increase again during the afternoon
and evening to SW 15-25 kts. Seas mostly 2-4 ft.

LONG TERM /Thursday through Sunday/...
As of 0430 Tuesday...High pressure remains centered over the
Wern Atlantic this week with a series of systems pushing across
the area. This will keep gradients somewhat pinched with SW
winds around 10-20 kt (occasionally higher gusts possible),
highest in the late afternoon and evening with thermal gradient
peaking. Seas generally around 3-4 ft during the long term
period, however the dominant period through at least midweek
will be on the shorter wind wave side, 5-6sec. So, expect bumpy
3-4ft wind waves out of the S/SW on top of weakening 1-2ft long
period swell out of the east.
