.DISCUSSION...
KEY MESSAGE 1...A hot and muggy afternoon across ENC today with
widespread temps in the mid 80s to 90s and heat indices around
100-109F inland. A diurnal Cu field along and out ahead of the
seabreeze has developed this afternoon with widely scattered
showers and thunderstorms already developing along the seabreeze
today. Latest RAP mesoanalysis shows widespread MLCAPE values
around 2000-3000 J/kg, low level lapse rates of 8-9C/km, and
deep layer shear values around 20-25 kts across ENC as of this
update. With the seabreeze providing the focus for lift, expect
ongoing showers and thunderstorms to increase in coverage and
intensity as the afternoon wears on under this favorable
environment for thunderstorm development. With ample CAPE, and
enough lift a few of these storms could become strong to severe
in nature bringing a threat for wet microbursts (up to 60 mph
gusts), frequent lightning, and heavy rain. Given the expected
scattered nature of this activity have capped PoPs at Chance as
not everyone will see rain and thunderstorms today.

Seabreeze thunderstorms gradually push inland through the
afternoon and begin to dissipate after sunset. However, as this
occurs deep layer shear will be on the increase with the
approach of an upper level trough, peaking at 25-35 kts out
ahead of an approaching cold front with the highest shear values
noted along our northern periphery. This will lead into our
next potential thunderstorm threat from the west. Latest
guidance suggests broken linear segments of thunderstorms will
develop along a surface trough to our west this afternoon across
central NC/VA and push E`wards this evening and overnight,
likely reaching the area after sunset. While instability is
forecast to be waning, with enough shear these segments could
hold together long enough to promote a second strong to severe
thunderstorm threat into tonight. Greatest risk for this second
round of storms looks to occur across our northern zones tonight
with this activity pushing off the coast by about 2AM Monday.
This activity would once again bring a threat for strong and
damaging wind gusts (40-60 mph) to the area. SPC has noted much
of the area under a slight risk (level 2/5) for severe
thunderstorms today mainly west of the coast and OBX with a
marginal risk (level 1/5) for severe thunderstorms noted
elsewhere across the coast and OBX.

Beyond tonight, overall pattern through the week remains at
least marginally conducive for shower and thunderstorm threats
each afternoon and evening. The next best chance for stronger
storms appears to be Thursday into Friday ahead of a stronger
front where deeper shear will likely be present with equally
strong instability.

KEY MESSAGE 2...As expected higher heat and humidity have hung
on today with widespread heat indices around or above 105F and
have kept the current heat advisory going until 00Z. Will note
given ongoing convection this heat advisory may be cancelled
early.

Once the first front passes on Monday, a relatively cooler
couple of days are likely. Heat and humidity will likely return
again on Thursday and Friday ahead of the late-week front with
more widespread heat index values of 105-110 forecast.

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
VFR conditions across the terminals early this afternoon. Winds
become gusty this afternoon before isolated to scattered
showers and thunderstorms develop over the area. Sct storms
likely along the sea breeze this afternoon with potential for
more robust convection likely to enter from the west later this
afternoon and evening, potentially impacting terminals through
03-04z. A few storms could be strong with damaging gusts
exceeding 40 kt along with tempo sub-VFR. Behind the convection,
another pre- dawn bank of low stratus could develop inland. Fog
appears less likely overnight with winds unlikely to decouple.

Outlook: Front clears area later Monday although iso to sct
shower and thunderstorm risk will extend into Tuesday and
Wednesday. More widespread convective threat returns Thursday
into Friday with stronger front. Overnight fog and stratus
threat possible each morning.

&&

.MARINE...
Once again little in the way of changes to the marine forecast
as we do expect conditions to worsen this afternoon as the
pressure gradient tightens between a surface trough and cold
front to our west and a ridge of high pressure to the east. SW
winds are already about 10-20 kts with a few gusts up to 25 kts
noted across our coastal waters already. With the aforementioned
cold front not forecast to cross our waters until Mon morning
expect widespread 15-25kt SW winds with gusts up around 25-30
kts across our coastal waters, Pamlico, Croatan/Roanoke Sounds
and Neuse River this afternoon and tonight. This coincides with
ongoing small craft advisories. Elsewhere slightly lighter
winds will be in place and dont plan on expanding ongoing SCA`s.
These elevated winds continue into Mon morning, but as a cold
front tracks across our waters winds will ease as the pressure
gradient relaxes with winds lowering to 5-15 kts with a few
gusts up towards 20 kts across all waters. Winds will also
become NE`rly behind the front. 2-4 ft seas this afternoon will
increase to 4-6 ft across our coastal waters this evening and
remain elevated into Monday morning before lowering down to 3-5
ft by 11AM Mon. This will bring an end to our small craft
advisories. Lighter winds and lower seas are then forecast
through the rest of the period with the front hanging around the
area. Outside of SCA conditions, there will be a renewed risk
of showers and thunderstorms especially after nightfall as more
organized convection inland migrates over area waters after 00z.
Environment will be favorable for a few stronger storms with
gusts in excess of 40 kt.

Outlook (Mon night through Sat): Periodic nocturnal and early
morning risk of showers and thunderstorms is possible each
weeknight, although most likely odds will be Thursday night into
Friday ahead of stronger front approaching area waters. This
front will also be the next focus of widespread SCA conditions
with a low risk of Gales across the outer waters.
