.DISCUSSION...
KEY MESSAGE 1...Latest analysis shows high pressure anchored
offshore and cold front moving towards the Appalachians early
this morning. The cold front and shortwave will continue to
push eastward today while weak low pressure develops along the
front. Modest instability (ML CAPEs 2-2500 J/kg) and bulk shear
(25-40 kt) will support organized convection this afternoon and
evening. SPC has upgraded eastern NC to a Slight risk of severe
thunderstorms (lvl 2/5) today (2pm-9pm). The main threat will be
damaging wind gusts, however a localized tornado threat could
develop wherever locally backed near sfc winds occur. Multi cell
storms likely to develop initially with the threat possibly
morphing into a qlcs ahead of the front. Moderate to locally
heavy rain will be possible, which could lead to a minor flood
threat...best chances for areas north of Hwy 264. Front will
sweep offshore around or shortly after sunset this evening, with
precip grad ending from west to east.

KEY MESSAGE 2...With the return SWerly flow, hot and humid
conditions combine to produce uncomfortably warm heat indices,
though most likely remaining below heat adv thresholds, with
readings in the lower 100s each day early to late week. Brief
break from the heat expected on Wed behind the fropa, when
afternoon highs only in the low 80s OBX zones to upper 80s
inland with lowered RH`s as well. Heating back up Thu into the
weekend. Typical summertime diurnal convective chances return Sat
into early next week.

.AVIATION /09Z TUESDAY THROUGH SATURDAY/...
VFR conditions prevail at the terminals early this morning.
Sufficient S to SW winds should curb fog development. There is
also limited chances for sub-VFR stratus with HREF probs less
than 20 percent, best chances along the coast. A cold front
will approach the area today, pushing across terminals late
afternoon into the evening hours. SW winds will gust around
20-30 kt ahead of the front, becoming northerly and diminishing
after fropa. Chances for showers and thunderstorms also increase
through the afternoon bringing a threat for strong to severe
thunderstorms with strong wind gusts and lightning the primary
threats with the storms. This may bring temporary sub-VFR
conditions to the terminals, with best chances between 18-00z.

Outlook (Wed through Sat): Pred VFR conditions expected. Mostly
dry for Wed and Thu with high pres rebuilding. Next precip
chance on Fri night into Sat with another system approaching.

&&

.MARINE...
Latest obs show SW winds 5-15 kt north of Hatteras and 10-20 kt
south, with seas 2-5 ft. SSW winds will increase through the day
ahead of an approaching cold front and low pressure, peaking at
15-25 kt gusting 25-30 kt this afternoon/early evening with
seas building to 4-7 ft. SCAs continue for the nearshore coastal
waters, Pamlico/Croatan/Roanoke Sounds and Neuse/Bay Rivers.
The front will move through the waters tonight with flow
becoming NW-N 10-20 kt behind it, along with grad subsiding
seas. Sct showers and storms expected in the afternoon and
evening, diminishing quickly behind the front, though some
lighter showers wrapping around the departing low will be
possible through around midnight.

Outlook (Wed through Sat): Moderate N-NE winds Wed, grad veering
becoming light Wed night into Thu. S-SW winds return Thu night
into Fri though looks to remain below SCA conditions. SW winds
increase to 10-20 kt Sat.
