.KEY MESSAGES...
1) Seasonably warm conditions through Thursday.

2) Dangerously hot and humid conditions for this 4th of July
weekend into early next week.

.DISCUSSION...
KEY MESSAGE 1...A weak area of low pressure meandering off the
NC coast will continue to slowly drift away from the region
tonight. Temps will warm slowly into the low 90s inland by
Wednesday and mid 90s on Thursday. Despite the warming,
relatively low TD`s in the 60s to around 70 will not make it
feel much hotter, with heat indices no higher than the 90s
through Wednesday, possibly reaching around 100 by Thursday.

KEY MESSAGE 2...The advertised heat and humidity will build
into ENC from the north and west Friday into the weekend. High
impact heat and humidity is expected, as the peak of it will be
during the busy 4th of July holiday weekend (Saturday through
Monday) with highs expected to reach well into the 90s inland,
possibly reaching 100 in some locales, with upper 80s to mid 90s
beaches. The combination of the heat and humidity will push
heat indices towards the 105 degree mark or slightly higher this
weekend. Overnight lows will also be warm due to the increased
TD`s, with lows around 80 near the coast, and mid 70s interior.

NWS probabilistic Heat Risk values peak Saturday into Monday in
the major (coast) to extreme (inland) range. The chance for
extreme heat risk has come down a bit on Saturday and Sunday to
around 40-60% inland with the compounding days and little relief
during the nighttime periods. Those sensitive to heat and
anyone planning on spending ample amounts of time outside this
weekend into early next week should monitor the forecast trends.

With the ridge of high pressure building in, a cap will develop
with little to no shower or thunderstorm relief esp on Saturday.
On Sunday, the ridge may break down just enough for some
scattered storms to develop mainly inland zones, but the chance
for rain is only 20-40% at this time. Better precip chances
expected early next week.

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
Low-impact aviation conditions are expected over the next 24
hours as high pressure builds in over the region. The one minor
note of consideration is that relatively light winds may support
a short window of reduced VIS from 09z-12z early Wednesday
morning (due to MIFG).

Outlook (Wednesday night through Sun): Dry weather is expected
to prevail with pred VFR conditions, but could see patchy fog
and low stratus each morning. Winds will be light through the
period with high pres in vicinity.

&&

.MARINE...
Latest obs show NE-E winds 5-15 kt with seas 3-6 ft (highest
across the outer central waters). Winds will continue to veer
easterly overnight as high pressure builds in and weak low
pressure lingers off the SE coast. Will continue SCA for the
outer central waters through the overnight with seas up to 6 ft,
though based on obs this seems a bit marginal at this time. E-SE
winds 5-15 kt Wed with seas mainly 3-5 ft.

Outlook (Wednesday night through Sunday): The Bermuda high
becomes dominant mid to late week with light winds 5-15 kt and
seas around 2-4 ft.
