Area Forecast Discussion
National Weather Service Wilmington NC
306 PM EDT Sat Jun 24 2017
.SYNOPSIS...
Deep tropical moisture will move across the region this
evening and linger through early Sunday, bringing an increased
chance of showers and thunderstorms to the region. Slightly
cooler and much drier air will move into the region early next
week. A warming trend will develop later in the week with
temperatures returning near normal Thursday through Saturday.
&&
.NEAR TERM /THROUGH SUNDAY/...
As of 3 PM Saturday...The afternoon convection began along the
ribbon of deep moisture that was located on an axis from Cape
Hatteras to central Georgia. The GOES-16 precipitable waters
indicated the values were around 2.2 inches. The SPC meso-
analysis paints an area of 1500 J/kg of mixed layer Cape along
this ribbon. Wet bulb zero heights continue to be very high at
levels above 13,000 feet. Shear is around 25 knots so at this
time wet micro- burst are the threat for this evening.
As a slow moving front nears the coast in the morning the chances
for showers and thunderstorms lowers in the I-95 corridor to a
slight chance by the afternoon. A high chance of convection is
possible through daybreak with chances slowly dropping through the
day.
Lows tonight will be in the middle to upper 70s and highs are in the
upper 80s inland an the middle 80s at the beaches.
The current tide forecast is for the water levels downtown to rise
to 5.65 feet at 11 PM so coastal flood advisory will most likely be
issued later this evening.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
As of 3 PM Saturday...Airmass change underway to start the
period as cold front makes slow progress to the coast. It may
hang up just close enough to the shore that some POPS will be
maintained for coastal areas into at least early Monday (though
not all guidance convinced as such). Even so, the dewpoints will
be dropping into the low to mid 60s as the drier air advects in
from the north and west. The deep moisture will continue to be
pushed offshore Monday night though shallow low level moisture
will linger near the front. AFter a seasonable and muggy Sunday
night the temps and dewpoints will be a few degrees below normal
Monday and Monday night.
&&
.LONG TERM /TUESDAY THROUGH SATURDAY/...
As of 3 PM Saturday...Longwave 5h trough over the eastern CONUS at
the start of the period lifts east-northeast Wed. Surface high
building in from the north Tue will move overhead Wed and off the
coast by Thu. As the Bermuda High sets back up Thu the pattern aloft
will transition from flat/progressive flow late Wed into Thu to
weak, but strengthening 5h ridging over the western Atlantic late in
the week. Arrival of the 5h trough will be accompanied by an
anomalously dry airmass. Forecast soundings drop precipitable water
values under half an inch Tue night into Wed. The exiting trough and
then the building 5h ridge will produce a significant amount of
subsidence through at least Thu which, combined with dry air, should
keep the region dry. Moisture starts to creep back in Fri as the
surface and mid level ridge setup in a more typical summer time
location. Moisture return may not be enough to support much more
than isolated sea breeze convection on Fri. Coverage will increase
Sat with both the sea breeze and the Piedmont trough becoming more
active. Temps early in the period will run about 5 degrees below
climo as an unseasonably cool and dry air mass builds in.
Development of return flow Thu will return temperatures to climo
late in the period.
&&
.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
As of 18 UTC...Convection beginning over inland TAF sites.
Coverage of convection is expected to increase and move to the
coast generally after 19 UTC and be in the general area through
midnight. Mainly VFR outside convection with MVFR ceilings and
isolated IFR visibilities if convection occurs over airport. At
this time will go with VCTS.
Extended Outlook...MVFR/IFR conditions are possible in
thunderstorms Sunday afternoon then mainly VFR conditions has
drier air moves in the area.
&&
.MARINE...
NEAR TERM /THROUGH SUNDAY/...
As of 3 PM Saturday...Currently at Frying Pan Shoals Buoy the wind
is from the southwest at 18 knots with gust to 20 knots and seas
running 5.5 feet. Closer to the coast at 41110 seas have fallen to 4
feet this afternoon. Winds are expected to remain at 15 to 20 knots
through midnight and weaken as the front gets closer to the coast.
Will continue with the small craft advisory through 6 AM but this
may be able to be lifted a few hours earlier.
Also, tides are forecast to fall below 1 foot tonight between 3 and
4 AM. So a Marine Weather Statement for low water levels especially
in and around inlet will need to be issued.
SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
As of 3 PM Saturday...West wind to start the period rather than
the more climatologically favored southwesterly flow as a cold
front enters the coastal waters. By Monday morning wind will
turn to the N or NE as the boundary decelerates and stalls just
offshore. The front washes out sufficiently Monday night to no
longer be a wind- maker and weak piedmont troughiness ought to
be able to allow a light SW flow to return.
LONG TERM /TUESDAY THROUGH THURSDAY/...
As of 3 PM Saturday...Northeast flow Tue following passage of a
cold front prior to the start of the period will continue into
Wed. Northeast flow starts a slow veering trend later Wed,
becoming easterly Wed night and ultimately southeast on Thu.
Gradient will remain weak for much of the period with speeds 10
kt or less. Exception will Tue night when a surge of cooler air
spreading down the coast pushes northeast flow close to 15 kt.
Seas will be around 2 ft through the period.
