Lightning Strike in South Carolina, June 14, 2018

Area Forecast Discussion
National Weather Service Wilmington NC
Issued by National Weather Service Newport/Morehead City NC
347 PM EDT Thu Jun 14 2018

.SYNOPSIS...
Showers and thunderstorms today will gradually become fewer
from north to south on Friday as a cold front slowly moves
through the area. High pressure will follow, briefly bringing
some drier air. As high pressure moves offshore early next week,
the heat will build with afternoon heat index values possibly
topping 100 degrees for much of next week.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 330 PM Thursday...Convection blossomed this afternoon as a
trough approached from the north, helping trigger showers and
thunderstorms along it and its convergence with an inland moving
sea-breeze boundary. Storms became severe mainly from Brunswick
to Pender counties where these boundaries converged, with much
less convective coverage farther inland. Boundary interaction
will continue southwest of the current warnings into Horry
county through peak afternoon heating, then severe potential
should diminish by 22-23Z.

The cold front dropping south through the area tonight will
bisect the region after midnight. North of the front, winds will
become light with potential for fog, so maintained patchy fog in
forecast through 11-12Z. A shortwave trough will move southeast
towards SE NC/NE SC after midnight which may help maintain
shower activity after midnight. Overnight lows will remain mild
with temperatures in the lower 70s.

The cold front will shift south of the NC/SC border Friday
morning and washout by midday while an area of high pressure
ridges south from the DELMARVA peninsula, shifting winds back
east and southeast by late in the day. Aloft, upper trough over
New England will shift east off the Gulf of Maine, with weak
shortwaves moving southeast across the region, providing
marginal support for diurnally driven convection. PWATs peak
around 1.75 inches by midday, then diminish late as the ridge
noses southwest over the area. Max temps will build into the
lower 90s inland to upper 80s along the coast, yielding heat
index values in the mid 90s.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/...
As of 330 PM Thursday...The ridge building in from the north
will shift more offshore through Saturday, effectively shifting
winds more southerly helping to increase moisture across the
area late Saturday. Diurnally driven showers and thunderstorms
are possible Saturday though capped POPs no more than 30 for
inland locations Saturday afternoon. Fog could again become an
issue for inland locations if winds can sufficiently decouple.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
As of 330 PM Thursday...Sfc high pressure migrating south will
settle well offshore almost due east of Cape Fear through early
next week. This will produce a SE to S return flow through much
of the period. At the same time, a highly amplified flow in the
mid to upper levels will build a ridge eastward leaving local
area in deep north to northwesterly flow between this ridge just
to our west and deep trough over the western Atlantic. Overall,
expect dry air and subsidence in the mid levels over the area,
but may see quite a bit of cirrus streaming down from the north
through the period and some aftn cu development. One exception
may be a couple of impulses dropping down in N-NW flow in the
mid levels. The models have been consistently showing some
convection flaring with this feature Sun or Mon. Pcp water
values down less than 1.25 inches may reach up to 1.8 inches in
any associated convection with mid to upper level impulses
possible late Sun into Mon and low level moisture on the rise in
increasing SW flow. The ridge will get suppressed to the west
and south as mid to upper trough digs down heading toward mid
week next week. Therefore expect increasing chc of shwrs Tues
into Wed.

As the ridge builds east, heights will rise and 850 temps will
increase to around 20c by Mon. This will produce temps well
into the 90s by Mon. Highs early next week may reach close to
100 inland with humidity levels rising as dewpoint temps reach
into the 70s. Should see heat indices reaching above 100 with
heat advisories possible next week.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
As of 18Z...Northwest flow associated with a cold front will
drive convection southeast through the CWA with southwesterly
winds ahead of the front. Convection is expected near 18-20Z
beginning first for LBT, shifting southeast as the boundary
interacts with the inland-moving sea-breeze. Most shower and
thunderstorm activity will be over by 22-23Z with debris
convection through the evening hours.

Extended Outlook...Widely scattered afternoon or evening
convection Friday, mainly across the SC terminals. Predominately
VFR Saturday through Monday with possible short duration
MVFR/IFR fog or low stratus each morning.

&&

.MARINE...
NEAR TERM /THROUGH TONIGHT/...
As of 345 PM Thursday...Do not anticipate any SCEC or SCA
requirements this period.

Latest surface and buoy data indicate SW 5-15 kt across the
waters this afternoon, with wind-wave dominant seas of 2-3 ft
nearshore and 4 ft seas reported by the Frying Pan Shoals buoy.
Expect SW winds around 10 to 15 kt this afternoon through late
this evening. As the west to east oriented cold front
approaches, winds will become more westerly around 10 kt and
after it's passage, NW to N at 10 to occasionally 15 kt. The
better push south of the local area occurs Fri morning and
beyond with N-NE winds in the 10 to 15 kt range with gusts to 20
kt. Seas will range 2-4 ft overnight, with the 4 footers
primarily from Cape Fear northward.

High pressure will begin to build south over the NC coastal
waters on Friday, shifting winds back east to southeast across
the waters, though remaining 5-15 kt with seas mostly 2-3 ft.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
As of 300 PM Thursday...A cold front is expected to bisect the
waters Fri morning and should eventually move S of all the waters
Fri night as high pressure builds from the N. The area of high
pressure should trend offshore Sat/Sat night. Winds across the
northern waters will be N to NE Fri morning before becoming
easterly Fri afternoon. Winds across the southern waters will
settle on E or SE Fri afternoon. The wind direction will become
predominantly E or ESE Fri night and Sat before veering to SE
later Sat and S later Sat night. Wind speeds will be 10 to 15 kt
for much of the period. Seas will be mainly 3 ft as an easterly
swell slowly strengthens through the period.

LONG TERM /SUNDAY THROUGH MONDAY/...
As of 300 PM Thursday...High pressure will build over the local
waters as it migrates farther east off of the NC Coast Sunday
through Monday. Therefore, winds will shift from S to SW late
Sun into Monday, basically remaining 10 to 15 kt with an
increase to 10 to 20 kt on Mon in increasing SW winds. Seas will
be on a downward trend through Sun with a steady rise Sun night
through Mon night in increasing SW push, ranging from 2 to 3 ft
Sun and 3 to 4 ft by late Mon.
