Area Forecast Discussion
National Weather Service Newport/Morehead City NC
718 PM EDT Mon Jul 7 2025

.SYNOPSIS...
A series of mid level systems will push across the area bringing
periods of unsettled weather through the rest of the week.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
As of 7 PM Monday...Chances for rain are quickly diminishing as
the last of the scattered showers and thunderstorms moves off
the NOBX. Expect mostly dry conditions this evening and
overnight with partly cloudy skies. Mild lows expected in the
mid to upper 70s.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...
As of 3 PM Monday...

Key Messages

 - Hot with heat index values peaking up to 106 degrees

 - A marginal chance for severe storms across the coastal plain
   in the afternoon.

High pressure continues off the coast Tuesday while a mid-level
shortwave pushing into the Ohio River Valley with thermal
troughing across the piedmont. Isolated to widely scattered
showers and thunderstorms expected to develop along the sea
breeze as well as the inland thermal trough which will propagate
toward our area through the afternoon. Strong sfc heating will
bring moderate instability with SBCAPE peaking around 2500-3000
J/Kg and could see some more robust storms producing strong
winds gusts despite meager shear of 15 kt or less and SPC has
the western coastal plain in a marginal risk for severe storms
Tuesday. Hot and humid conditions will persist with temps a
couple of degrees warmer, in the mid 90s inland and upper
80s/lower 90s along the coast. With dew points in the mid 70s,
heat index values are expected to peak around 103-106 degrees
and have issued a Heat Advisory for all but the coastal zones.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
As of 3 PM Monday...A similar set up to Tuesday afternoon is
expected for Wednesday, with a similar threat of strong to
severe storms exists over the coastal plain. ~2000 J/kg MLCAPE
coupled with meager bulk shear will limit the overall severe
threat. SPC has the far western portions of the CWA in a
marginal risk, mainly for the potential for isolated damaging
wind gusts. Elevated PWATs will continue to support a risk for
heavy rainfall and isolated flooding, with WPC having a marginal
ERO for the western forecast area on Wednesday.

With increasing thicknesses due to the building ridge, the
warm temps expected Tuesday are forecast to continue into
Wednesday with MaxTs in the low 90s inland from the coast and
peak heat index values around 100-105.

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 3-5 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.

.AVIATION /23Z MONDAY THROUGH SATURDAY/...
SHORT TERM /through Tuesday/...
As of 7 PM Monday...

Key Messages

 - VFR conditions will prevail through tomorrow afternoon

High pressure offshore will provide mostly clear conditions
overnight, though some residual low level moisture may bring the
development of some low stratus at 2000-3000 ft. Not sure how
widespread this will be or to what areal extent, so will include
just a scattered group in the TAF this evening. Breezy
conditions overnight will keep fog at bay. VFR conditions
expected tomorrow with mostly sunny skies. Rain and
thunderstorm chances increase late tomorrow afternoon, but
remain at or below 30%.

LONG TERM /Tuesday night through Friday/...
As of 3 PM Monday...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.

&&

.MARINE...
SHORT TERM /through Tuesday/...
As of 7 PM Monday...A strong thermal gradient across the Pamlico
and Croatan/Roanoke Sounds and coastal waters north of Cape
Hatteras will cause wind gusts of 25-30 kts to persist through
late this evening. As a result, SCAs have been extended until 1
am.

Conditions will improve through the overnight with winds
diminishing to 10-15 kt late tonight. Expect to see a tightening
pressure gradient tomorrow between the inland thermal trough
and offshore high pressure with daytime heating bringing winds
back to around 10-20 kt. Seas will subside to 2-4 ft tonight and
continue through tomorrow.

LONG TERM /Tuesday night through Friday/...
As of 3 PM Monday...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 1-2ft long period
swell on the order of 13-15sec out of the east.
