.KEY MESSAGES...
1) Unseasonably warm, moist, and unstable airmass will support
some scattered thunderstorms today ahead of cold front.

2) Drier and cooler behind a cold front Fri into Saturday.

3) Another reinforcing cold front moves through Saturday night,
bringing an even cooler and drier airmass into the region
Sunday.

4) Next chance for showers arrives for the beginning of the work

.DISCUSSION...
KEY MESSAGE 1...Another round of showers and thunderstorms is
possible today, esp this afternoon across srn portions of ENC.
There will be multiple forcing mechanisms at play (front moving
south and sea/river/sound breezes), and where these interact
will present the best chance for deeper convection. The
environment will be more impressive with 30+ kt of bulk shear,
strong instability (1500-2000 J/kg MLCAPE), and 2" PWATs.
However, early morning showers and storms may act as a
`stabilizing` agent, along with debris clouds from said
activity, thus limiting severety and covg of storms. The
RRFS/HRRR has backed off on coverage of storms, and thus have
decreased pops from likelies, to high chc and retained the
highest chances for the southern areas, generally south of Hwy
70. If some storms manage to develop, they may utilize the
aforementioned deep layer shear that will be available and could
pose a localized convective wind threat, with some hail possible
as well.

KEY MESSAGE 2...The cold front will clear the area this evening,
leaving drier and cooler conditions in its wake on Friday as NE
flow develops. The front will lift back north as a warm front
on Saturday, though dry air in place will limit higher chances
for showers, and thus have cont to trend lower with shower
chances on Sat, with less than 10% chances for the north, and no
higher than 30-40% srn zones.

KEY MESSAGE 3...Reinforcing cold front will move through on
Saturday night, which will bring even drier and cooler temps for
the beginning of the week, with temps actually dropping below
climo for a change, with 75-80 for highs, and mid 50s inland to
low 60s coast for lows.

KEY MESSAGE 4...By Monday, return flow develops as high
pres shifts offshore and weak isentropic lift develops out ahead
of yet another cold front set to pass through late Mon or early
Tue. Ensemble spread remains high for the strength of this
system, but lack of appreciable instability means that mainly
light showers would accompany this system, and pops only in the
30% range at this time.

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
Retained VCSH for some precip that will slide through ENC
through the morning with advancing cold front. Otherwise
generally expect VFR conditions after some morning MVFR stratus
burns off by mid morning. VFR conditions then return to all
areas. Chances for storms has decreased today, and with lack of
appreciable coverage, have not indicated a prob30 or VCTS yet
for potential activity this afternoon. Will include a VCSH
mention for OAJ later this afternoon as this area has the best
chance of receiving precip with southward advancing front late
in the day.

Outlook (Thursday night through Monday): Drier and cooler
conditions are expected behind the front beginning tonight and
lasting through the weekend. A small chance for light showers on
Sat, but forecast trending drier. Next best chance for precip
will be on Monday with yet another cold front set to pass
through Mon night.

&&

.MARINE...
20-25 kt cont for the coastal waters south of Oregon Inlet, but
the winds have diminished below 25 kt for Pamlico so have
cancelled the SCA here. Seas will remain at 6 ft through about
mid- morning for the coastal waters. SCAs will remain in place
through that time.

Outlook (Friday through Monday): Cold front will push south of
the waters by this evening, with winds becoming N to NE behind
the fropa from north to south across ENC and remaining through
late Fri. Winds will remain below SCA levels behind the front,
with seas generally 2-4 ft. Winds turn back around to the S on
Sat as the front moves back north as a warm front. Then another
front moves through Sat afternoon and evening, with winds
becoming N to NE again and strengthening to SCA levels for at
least the coastal waters and Pamlico Sound, with seas responding
by building to 6+ ft. SCA will likely be needed for later Sat
through Sun.
