AREA FORECAST DISCUSSION
National Weather Service Raleigh NC
740 PM EDT Sun Jul 5 2020

.SYNOPSIS...
A stationary front stretching from the NC Crystal Coast to the
Piedmont will weaken through tonight. Meanwhile, subtropical high
pressure will extend across the cntl Appalachians and NC through
Monday night.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 430 PM Sunday...

Convection has materialized generally as expected this afternoon,
but with no reports of severe weather despite a couple of SVR
Warnings. As subsequent convection develops on outflow and spreads
away from the primary moisture and convergence axis noted
previously, it will do so in an increasingly dry and less favorable
environment to the north and south for any vigorous convection. And
in conjunction with the onset of nocturnal cooling in a few hours,
that suggests convective coverage and intensity will wane in cntl NC
in the next few hours. Until that time, the area centered around
Johnston, Wayne, Wilson, and nrn Sampson Co. remains in a relatively
maximized near storm environment between outflow approaching from
all directions; and those counties will likely be the focus for
another strong to severe cell or three through 22-23Z.

.PREV DISCUSSION... /ISSUED 1135 AM EDT Sun Jul 05 2020/

12Z upr air data indicate a (700-500 mb) subtropical ridge has
expanded from the OH Valley to the cntl Appalachians and NC this
morning. Associated anticyclonic flow and generally subsident
conditions will result over cntl NC. And observed proximity
soundings this morning from VA to the Carolinas continue to depict a
subsidence inversion between 600-650 mb, one relatively least
prominent at GSO. An axis of relatively maximized 925-850 mb
moisture, characterized by lwr-mid teens C dewpoints in that layer,
was analyzed from MHX to GSO, with drier air flanking to the
northeast at WAL and and southwest at CHS.

At the surface, a front --one which generally coincided with the
aforementioned axis of maximized 925-850 mb moisture and has been
reinforced by maritime ely flow and outflow from convection Sat and
Sat night-- has become quasi-stationary from the Crystal coast wnwwd
across the Piedmont, roughly along I-40, to a lee trough/weak lee
low (1015 mb) centered near HKY/SVH. Both boundaries will remain
quasi-stationary today and likely serve as foci for mainly
scattered, diurnal convection. Meanwhile, weak, 1017 mb high
pressure just offshore the middle Atlantic coast will extend swwd
with a slightly cooler and more stable air mass expected from the
DelMarVA swwd into nern NC.

Convection will again be limited in intensity by the presence of the
inversion warmth/dryness in the mid levels, and also weekly-steered
and sheared, and slow-moving given the presence and proximity of the
subtropical ridge and less than 10 kts of flow from the surface to
400 mb; and localized heavy downpours will result. Despite the slow
movement, only modest precipitable water values of 1.5-1.7 " suggest
any associated flooding would be very localized. Instead, the
primary hazard today will again be from strong to locally damaging
wind gusts owing to the presence of a high DCAPE environment already
in place per 1150 J/kg values sampled at both GSO and RNK this
morning. And forecast models indicate the DCAPE will increase into
the 1200-1500 J/kg range through this afternoon. Convection will
likely diminish from late afternoon onward as outflow and subsequent
forcing mechanisms move away from a moderate instability axis along
the front, into the foregoing drier and more stable environments
flanking cntl NC to the ne and sw.

Otherwise, it will be hot again, with temperatures mostly in the lwr
90s, and with surface dewpoints that will be less prone to mixing
out than previous days. As such, maximum Heat Index values will
reach the mid 90s to around 100 degrees. Generally persistence low
temperatures in the upr 60s to lwr 70s are expected with variably
cloudy but dry conditions tonight.

&&

.SHORT TERM /MONDAY AND MONDAY NIGHT/...
As of 400 PM Sunday...

Subtropical ridging centered in the 700-500 mb layer will continue
to extend from the OH Valley to offshore the NC coast this period.
Meanwhile, a broad mid-upr level low --one comprised of several
smaller-scale perturbations from the mid and lwr MS River Valley to
the Gulf coast and n-cntl GOM this afternoon, will drift ewd and
become centered across the TN Valley and srn Appalachians by 12Z
Tue. At least a couple of the perturbations orbiting the mean low
will lift newd across the Savannah Basin and the wrn or w-cntl
Carolinas Mon afternoon-night and promote some weakening/erosion of
the preceding subtropical ridge.

At the surface, ridging and anticyclonic flow will extend from the
wrn N. Atlantic wwd into NC. The ridging will be flanked by an
Appalachian-lee trough to the north over VA and a surface trough
over nern FL wwd across srn GA and AL this afternoon, which is
forecast to lift nwd into SC and srn NC late Mon and Mon night. A
sea breeze will also likely make good progress nwwd into cntl NC
during the afternoon and evening, given prevailing onshore flow.

As such, cntl NC will be situated in a relative lull of convection,
with the srn of the two regimes described above likely to spread
north and affect the NC srn Piedmont, Sandhills, and srn-cntl
Coastal Plain during afternoon-evening. Associated clouds may keep
those srn areas up to a few degrees shy of persistence highs in the
lwr 90s that are expected otherwise and elsewhere. A chance of
showers and storms will persist throughout the night centered over
the srn Piedmont, as well as a good chance of low stratus there, in
closest proximity to the lift approaching from the surface to mid
level troughs approaching from the southwest. Lows mostly in the lwr
70s.

&&

.LONG TERM /TUESDAY THROUGH SUNDAY/...
As of 330 PM Sunday...

Not a whole lot has changed in the extended. The medium-range models
still have a weak upper low over the Deep South slowly drifting east-
northeast and amplifying a weak trough before moving east through
the region midweek. The model trend has been for the low to
strengthen along the Carolina coast by Thursday and either stalling
out or slowly lifting northeast along the coast through the weekend.
Given the continued model differences, still a lower than normal
forecast confidence Thursday onward. However, regardless of how the
aforementioned low evolves, both medium range models indicate a
northern stream trough amplifying as it moves through the Great
Lakes/Northeast over the weekend. The trough axis will remain over
the region through the remainder of the extended forecast area, with
shortwave impulses moving through it. At the surface, south-
southeasterly flow into the area off the Atlantic will persist, with
high pressure to the east and relatively low pressure to the west.
Though agreement is not great, still expect the development of a low
over the Carolinas in response to the low aloft, but confidence with
exactly when it would impact central NC is low at this time.
Regardless of the coverage, still expect shower and thunderstorm
activity to be diurnally driven through at least Thursday and best
chances to be across the southern portions of the area. Temperatures
should be within a category or two of normal through the period,
with the best chance for below normal highs on the days with and
where the more extensive cloud cover and convection occur. Highs
will generally be in the mid 80s to low 90s and lows in the upper
60s to mid 70s.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
As of 740 PM Sunday...

Afternoon and early evening storms essentially from FAY to RDU to
RWI have mostly diminished or propagated westward into the central
Piedmont, and should continue to migrate slowly around the western
Piedmont and perhaps impacts GSO/INT before completely dying off
after 03Z.  Probability is low but confidences is high enough to
include in the GSO/INT TAFs for a few more hours.

Fog and stratus coverage overnight is not expected to be a great as
it was last night, but earlier rain at RDU/ and climatology mat
support at least some MVFR vsbys by 09Z, with otherwise VFR across
central N.  A few isolated storms will be possible again Monday
afternoon, primarily in the vicinity of FAY

Outlook: The chance of showers and storms will increase through mid-
week, as low pressure approaches our region from the southwest.
Humid, sely flow off the sw N. Atlantic/Gulf Stream will also
increase the probability of morning stratus during that same time,
some of which could linger as MVFR ceilings through late morning to
midday Tue-Wed.
