Area Forecast Discussion
National Weather Service Wilmington NC
821 PM EDT THU JUL 7 2016
.SYNOPSIS...
Oppressive heat and humidity will build through Saturday with heat
advisories likely each day. Thunderstorm chances will be greatest
late today beneath an upper disturbance, before falling Friday and
Saturday. Temperatures will slowly drop back to more seasonable
levels by early next week, accompanied by increasing shower and
thunderstorm chances as a trough stalls near the area.
&&
.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
As of 800 PM Thursday...First batch of severe thunderstorms has
moved off the Cape Fear coast. Other severe thunderstorms were
moving by to our NE. Another cluster of severe thunderstorms was
upstream of Darlington County and moving southeast. Some of these
storms may still impact portions of our western counties before
the overall intensity of the thunderstorms begins to diminish.
Therefore, the Severe Thunderstorm Watch will continue. Have
dropped POPs back to chance as the coverage should be more
scattered through the late eve hours as a good portion of the
forecast area has been worked over from previous convection.
A Severe Thunderstorm Watch is in effect til 11 pm for all of
southeast North Carolina and northeast South Carolina. Main risk
will be damaging wind gusts and frequent cloud to ground
lightning.
Mins tonight will again be tricky dependent upon convection
creating some rain cooled air. Have sided more heavily on the
slightly cooler MAV numbers, with mins forecast to fall to around
72 well inland, 78 at the beaches.
&&
.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/...
As of 800 PM Thursday...A Heat Advisory has been issued for the
entire area for Fri for heat index values up to 109 degrees. Near
record heat forecast for the short term as Bermuda high and mid-
level ridging expand further across the area.
A shortwave will be moving offshore Friday morning with subsidence
likely developing behind it. As this occurs, the mid-level ridge
axis will blossom across the MS VLY, producing NW winds /downslope
flow/ into the Carolinas. This allows a piece of the thermal ridge
across the Great Plains to advect eastward, pushing 850mb temps to
21-22C Friday, and then to as much as 23C locally on Saturday, which
would be records for the date. These will combine with W/NW flow
through much of the column to produce the hottest temperatures we
have seen so far this year. Guidance is in good agreement with 100+
degree readings except at the immediate beaches on Saturday, with
highs Friday just a degree or two cooler. Downsloping may even
permit the favored hot areas in Cape Fear to be as hot if not hotter
than the rest of the CWA. At the same time, dew point temperatures
will increase from Wed/Thu, and heat advisories are expected with
excessive heat warnings possible for portions of the area Saturday
thanks to heat index values potentially exceeding 110.
Record temperatures for Fri/Sat:
Location Fri July 8 Sat July 9
Wilmington 100 - 2012 102 - 1977
Florence 105 - 1977 104 - 1977
N Myrtle Bch 97 - 2010 100 - 1992
Convection will be possible each day simply due to extreme
instability in these very hot temperatures. W/NW mid-level flow will
keep the column relatively dry, and warm 500mb temps will serve as a
lid to convection. However, the piedmont trough may be able to drive
updrafts into storms Fri/Sat, with any weak impulses moving to the
north aiding in development. Will maintain inherited silent POP for
Friday, with just a SCHC Saturday. Mins both nights will drop only
to around 80, upper 70s inland.
&&
.LONG TERM /SUNDAY THROUGH THURSDAY/...
As of 330 PM Thursday...The H5 subtropical ridge will be in place
across the northern Gulf of Mexico across FL and off the southeast
U.S. coast with peripheral influence across this segment of the
Carolinas. H85 temperatures are shown to lower a couple degrees C
through the extended with slightly lower dewpoints are expected
through the week. This could be enough of a change to hold heat
indices to at or just below 100F versus the 105-110F projected
during the short term. However, during Sunday afternoon the heat
index across the Pee Dee could range from 100-105F. A weak impulse
aloft during Sunday could lead to widely scattered showers/tstms
persisting into the evening hours. Otherwise inland trough and sea
breeze may produce similar coverage of storms during Monday with
an increase in coverage Tuesday through Thursday.
&&
.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
As of 00Z...Showers and thunderstorms will continue to affect the
terminals this evening. Generally TEMPO MVFR with this activity but
very brief IFR/wind gusts to 35 kt is possible. Activity will end
from NW-SE 02-04Z. Expect VFR after midnight all terminals with SW-W
winds 4-9 kts. After sunrise winds will be W around 10 kts except
becoming SW at the coastal terminals 10-15 kts by noon. Showers
and thunderstorms tomorrow should be mostly N of KILM/KLBT, but
could move S towards KILM/KLBT late in the TAF valid period.
EXTENDED OUTLOOK...Mainly VFR. Possible brief MVFR/IFR from
scattered convection each day. Possible brief MVFR from fog each
morning.
&&
.MARINE...
NEAR TERM /THROUGH TONIGHT/...
As of 800 PM Thursday...Gradient winds, enhanced by the seabreeze
circulation, have been stiff this eve...regularly 20 to 25 kt
with some gusts up to 30 kt. A thunderstorm wind gust across the
northern waters resulted in a brief period of even stronger winds
earlier.
Expect winds of 20 to 25 kt will continue for several more hours,
even as the seabreeze circulation breaks down, as nocturnal
jetting develops. May end up extending the Small Craft Advisory
later this eve. The low-level jet should weaken during the late
night hours, allowing winds to drop to 15 to 20 kt. Seas of 3 to 5
ft and up to 6 ft will subside to 3 to 4 ft Friday morning.
SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
As of 300 PM Thursday...More of the same through the short term as
Bermuda ridging remains the dominant feature. This leaves W/SW winds
across all portions of the waters, with the exception being a
slightly backed near-shore sea breeze each aftn, returning to W/SW
in the evening. Speeds will be elevated, 10-15 kts during the day
and 15-20 kts at night. Wave heights will be generally 3-4 ft with
isolated 5 fters at times, created primarily by a 5-6 sec SW wind
wave.
LONG TERM /SUNDAY THROUGH TUESDAY/...
As of 300 PM Thursday...A weak front will push off the waters
during Sunday morning then wash out with the return of
southwesterly flow by the afternoon. Weak inland troughing
combined with high pressure far offshore GA/FL will maintain
southwesterly flow across the waters Monday through Tuesday.
Speeds will average 15 knots or less through the period while seas
are generally 3-4 ft away from the coast. The bulk of the spectral
wave energy will be comprised of the dominant south-southwest wind
wave with a much smaller contribution from ESE ground swell.
