Area Forecast Discussion
National Weather Service Wilmington NC
320 PM EDT Sat Jun 3 2017

.SYNOPSIS...
Weak high pressure will bring slightly above normal
temperatures through the weekend. The risk for showers and
thunderstorms will be on the increase early next week ahead of a
cold front. High pressure mid and late next week will bring a
return to dry weather.

&&

.NEAR TERM /THROUGH SUNDAY/...
As of 300 PM Saturday...Summer-like temperatures with a mix of
sun and clouds this afternoon, with enough low level moisture
for cu field development along with isolated diurnal convection.
Much like yesterday, very dry air aloft will limit this
convection in height and coverage. Expect a dry overnight period
with clear skies and lows in the upper 60s.

The latest WPC surface analysis drapes a front just south of the
forecast area, but this is very diffuse and hard to pick out. Model
soundings show that at the surface we can expect anything from a
light southerly flow to light and variable winds, while a deep and
dry westerly flow will prevail aloft. This will again act to
suppress convection on Sunday, with isolated diurnal showers and
thunderstorms and temperatures within a degree or so of what we are
experiencing today.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
As of 300 PM Saturday...Expect an active short term period
highlighted by a cold front moving into the area late Monday
into early Tuesday. Abundant moisture will be provided by cutoff
mid level low pressure meandering in the lower Mississippi
Valley with the low level front slipping down from the northwest
powered by a mid level vortex across the Great Lakes. With
precipitable water values above 2.00 inches for most of the
period and good forcing, I am a little concerned forecast
guidance seems to by a bit on the light side regarding QPF. It
is worth noting some of our most notable flooding events outside
of tropical activity have been with a west to east oriented and
slow moving front, which is what will be in place here. Of
course the severe threat is always present this time of the
year. It appears although CAPE values are sufficient, weak 0-6km
shear values near 20kt will preclude a significant event. As
with the flooding threat however an east to west oriented front
in convective season always garners extra attention. No real
headlines for temperatures through the period with highs in the
middle to upper 80s and lows in the lower to even middle 70s.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
As of 315 PM Saturday...Latest guidance continues to suggest a
cold front situated across the forecast area Tuesday morning, as
it's associated upper level trough remains north of the area.
As a result, anticipate plenty of clouds and scattered showers
and thunderstorms in the morning hours as ample available moisture
remains in place. Expect conditions to taper off into the
afternoon hours as drier air begins to slowly infiltrate in
behind the front. By midweek, a bit of a disagreement arises
between the GFS and ECMWF for the placement of the (anticipated)
closed upper low stretching from the Ohio Valley into the NE.
At the same time, guidance suggests the development of a
coastal low across the northern portions of FL, placing our
forecast areas in between the two synoptic features. With that
said, do not anticipate much in the way of precipitation
Wednesday through Friday, though would not entirely rule out an
isolated shower or thunderstorm on Thursday. Otherwise,
anticipate the remainder of the week to be fairly quiet,
weather-wise. Another frontal passage is possible towards the
end of the extended.

As for temperatures, high's in the lower 80's inland to upper 70's
along the immediate coast are expected through the end of the week,
with overnight low's in the low to mid 60's. An upward trend into
the mid to upper 80's begins by the weekend.

&&

.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
As of 18Z...High confidence VFR through at least midnight for
all terminals. Low chances for showers in the vicinity of FLO
this afternoon handled by VCNTY phrasing. Modest confidence MVFR
VSBYs in the pre-dawn hours of Sunday all terminals except FLO.
Low confidence brief IFR cigs in stratus for ILM Sunday
morning.

Extended Outlook...Chance of flight restrictions with showers
and thunderstorms ahead of a frontal passage, especially Mon
afternoon and Mon night when we expect the greatest coverage of
convection.

&&

.MARINE...

NEAR TERM /TONIGHT THROUGH SUNDAY/...
As of 300 PM Saturday...A slack gradient will keep winds light
through much of the period, generally at 10 kts or less. Winds
will likely increase into the 10 to 15 kt range Sunday afternoon
as the gradient tightens in advance of the next cold front.
Seas will range right around 2 ft through the period.

SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
As of 300 PM Saturday...The coastal waters break out of the
summer like doldrums during this period as a cold front
approaches from the northwest. Initially the south to southeast
flow of 10-15 knots will remain in place through midday Monday.
Wind speeds increase steadily from that point on to reach a
maximum of 15-20 knots moreso from the southwest and probably
leaning more toward the higher end of the range. Small craft
seas will likely develop late Monday and persist into early
Tuesday on the heels of the stronger winds. Early in the period
significant seas will be 2-4 feet.

LONG TERM /TUESDAY THROUGH THURSDAY/...
As of 315 PM Saturday...NE winds around 10 to 15 kts Tuesday
morning will become WSW around 10 kts in the afternoon hours as
a cold front pushes across the waters. Overnight into Wednesday
morning, winds veer to the north again, remaining sustained
around 10 kts, only to become NNE and 10 kts or less through
into Thursday. Seas will remain around 1 to 3 ft.
