Area Forecast Discussion
National Weather Service Wilmington NC
227 PM EDT Fri Aug 24 2018
.SYNOPSIS...
A stalled front offshore will dissipate this weekend. High
pressure will build over the Carolinas and remain through the
middle of next week. Temperatures and humidity will creep back
to typical summertime levels.
&&
.NEAR TERM /THROUGH SATURDAY/...
As of 300 PM Friday...High pressure is ridging from central
Pennsylvania along the axis of the Appalachians along with a trough
of low pressure off the coast created by the dissipating frontal
boundary. At the surface, dewpoints range from the lower to
middle 50s well inland to the middle 60s along the coast with
Georgetown being the lone dewpoint at 70 degrees. Aloft the
lower precipitable waters are expected to remain through
Saturday.
The question is whether the area will see any showers along the
coast. The latest model runs are showing a weak low moving up the
old front and this will back the winds more to the northeast and
thus models are showing the showers remaining off the coast. So have
removed the isolated showers from the forecast. If a shower does
develop the coastal areas south of Myrtle Beach would be the likely
location.
Temperatures tonight should make a comfortable evening for the 2nd
weekend of high school football. Lows tonight are expected to drop
into the middle 60s inland to the lower 70s at the beaches.
Temperatures on Saturday will top out at the upper 80s inland to the
middle 80s at the beaches.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 300 PM Friday...Though weakening, high pressure will remain
north of the area until midday Sunday at which time it shifts
offshore. A shortwave will traverse the area on Sunday but forecast
soundings show conditions far too dry (PW 1.5") to support any
meaningful rain chances. Rain-free conditions will continue into
Sunday night as PW values remain the same and the diurnal wane of
instability occurs. Temperatures will be close to climatology
through the period.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
As of 300 PM Friday...All models position the subtropical ridge
directly over the Carolinas for most of next week, supporting
surface high pressure just offshore. The net effect should be
several days of dry weather, mostly sunny skies, and warm
temperatures. 850 mb temps around +18C will support highs in the
lower 90s inland and upper 80s on the coast, with no more than
2 degrees of spread among any of the model guidance. Dewpoints
will creep back into the 70s even inland, and heat indices could
eclipse 100 degrees again Tuesday and Wednesday.
The subsidence inversion associated with the upper ridge should
be strong enough to prevent any showers from developing Monday
and Tuesday, and probably Wednesday as well. By Thursday the
ECMWF (and to a lesser extent the GFS and Canadian) show a
weakness developing in the ridge as shortwave energy moves from
the Great Lakes into the Mid-Atlantic region. My forecast PoPs
Thursday are limited to no higher than 20 percent, then 30
percent on Friday.
&&
.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
As of 18Z, high pressure to the north continues to funnel dry
air into the area. There is high confidence that this will
maintain VFR conditions throughout the period. With a slow
arrival of moisture from the south. Dry conditions will likely
continue tomorrow with a similar forecast.
Extended Outlook, moisture will slowly work its way back to the
north and take us back to reality. Afternoon thunderstorms will
become more likely as we return to our typical summertime
pattern.
&&
.MARINE...
NEAR TERM /THROUGH SATURDAY/...
As of 300 PM Friday...A trough of low pressure off the coast created
by the dissipating cold front that passed offshore on Wednesday
night is expected to remain off the coast per the latest models.
East to east-northeast winds are expected to shift to the northeast
as a weak low translates up the old boundary. Winds will begin
around 10 to 15 knots tonight and will slowly weaken to 5 to 10
knots by late Saturday. Seas will fall from 3 to 4 feet tonight to 1
to 2 feet by late Saturday.
SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 300 PM Friday...Winds remain very light through the
period and show a gradual veering in direction. High pressure
initially centered north of the area-then forecast to move
offshore by about midday Sunday. With such light winds and no
swell energy seas will be capped at 2 ft.
LONG TERM /MONDAY THROUGH WEDNESDAY/...
As of 300 PM Friday...High pressure centered just offshore will
maintain dry weather and a gentle southwesterly wind across the
area. Inland temperatures are expected to get quite hot each
afternoon, developing a seabreeze circulation that will
increase nearshore winds to at least 10 knots. An 8-second SE
swell will be supplemented by a small wind chop each afternoon
and evening, totaling only 1-2 feet. The high should be strong
enough to prevent more than isolated showers at best.
&&
.TIDES/COASTAL FLOODING...
As of 300 PM Friday...A coastal flood advisory was raised for
the Cape Fear River downtown with river levels expected to be
above 5.5 feet between 8 PM and 11 PM. Water levels are expected
to reach a maximum of 5.85 feet around 9 pm. Also, water levels
at Wrightsville beach are expected to fall just below advisory
conditions at high tide around 7 PM tonight.

1 rip current. Local standard time, as filed.
At Myrtle Beach near 9th St, a man drowned attempting to rescue his daughter who was caught in a rip current.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
