AREA FORECAST DISCUSSION
National Weather Service Raleigh NC
255 PM EDT Tue Jun 9 2020

.SYNOPSIS...
In the wake of the warm front, southerly flow will advect warm moist
air into central NC as the sub-tropical ridge extends into the mid-
Atlantic. A cold front will slowly approach from the west through
Thursday. This front will stall and remain over central Carolinas
through Friday.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 200 PM Tuesday...

As of 12Z today, Tropical Depression Cristobal was located over
Missouri, remaining east of the low over western KS as it continues
its northward trek toward Canada. The sub-tropical ridge remains in
place over the Southeast and mid-Atlantic regions. With the warm
front lifting north through central NC today, southerly flow will
increase into the area, resulting in an increase of temperatures,
moisture and instability. Scattered showers with isolated
thunderstorms will continue to develop over and/or move into the
area through this evening. Best chances for showers and storms will
be over the southwestern two-thirds of the area. Highs today should
top out in the mid 80s to around 90 degrees. Lows will be on the
muggy side, low to mid 70s most places.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
As of 255 PM Tuesday...

The mid/upper level ridge axis will shift further east on Wednesday
ahead of the shortwave currently over Front Range.  That shortwave
will swing through the Midwest and Oh Valley, deamplifying
significantly as it does so, while the associated surface cold front
tracks east across the mountains early Thursday.  Ahead of the front,
a moderately unstable airmass owing to highs in the upper 80s and PW
rising above 1.5" will lead to scattered to numerous showers and
storms by midday, focused primarily in the Foothills and western
Piedmont from differential heating.  However, guidance shows a
secondary PW surge associated with the Bermuda high that will focus
across the coastal plain, so POPs end up relatively uniform across
the CWA.  Severe threat is limited given the lack of forcing and
shear, and the trough passing to our NW should veer the mid-level
flow sufficient to give storms some movement and limit flooding
potential.

Expect showers and storms will continue across the western piedmont
Wednesday night as the cold front approaches from the west.  Again,
with only remnant boundaries and an unseasonably moist atmosphere to
support the showers, its unclear how much coverage there will be
overnight, at least not until the cold front emerges from the
mountains.  Lows in the upper 70s and lower 70s.

The cold front is forecast to cross the mountains Wednesday night,
though guidance continues to slow its progress without any upper
support, and both the GFS/ECWMF hang it up in the Piedmont on
Thursday before finally pushing it toward the coastal areas by
Fri/Sat.  Models indicate the primary moist axis lying through the
heart of the Piedmont Thu, and soundings show moderate instability
with up to 1500 MLCAPE once again.  The lack of upper forcing and
deep layer shear should limit the severe threat to just wet
microbursts, but given the generally weak steering flow and very
weak MBE's, flash flooding from slow moving or back-building
multicells looks like the primary threat.  FFG is relatively high
given a week or so without significant rainfall, so the threat may
be confined to mainly urban areas.

The humid airmass and cold front will linger Thursday night,
continuing the potential for showers and storms.  Highs Thursday in
the mid 80s with lows in the mid 60s west to lower 70s east.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
As of 255 PM Tuesday...

With the front only creeping to the coast, scattered showers and
storms are possible again in the coastal plain Friday.  A second
cold front is then forecast to approach the area over the weekend as
an upper low over the NE slides south to the Mid-Atlantic, or even
splits into a second upper low over the southern Appalachians. The
patterns continues to be complicated and not handled consistently by
the models, but it is also a pattern that strong favors below normal
highs in the upper 70s by early next week and daily chances of
showers and storms, perhaps above June climo.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
As of 140 PM Tuesday...

24 hour TAF period: Scattered showers and isolated thunderstorms are
expected across much of central NC this aft/eve, most likely
impacting KINT, KGSO and KFAY. Aviation conditions will largely be
VFR, with the exception of under heavy thunderstorms/showers,
through midnight. MVFR/IFR cigs will develop shortly thereafter and
remain at best in those categories through daybreak Wednesday. A
period of LIFR/VLIFR cigs is possible at all terminals in the hours
around dawn. Cigs will slowly lift back to VFR through the morning,
returning to VFR around noon or so. Winds should be light and
generally southerly throughout the TAF period. -KC

Looking ahead: Sub-VFR (or low-end VFR) conditions are likely to
dominate the rest of this week, with much more clouds than sun as a
warm/humid air mass holds over central NC. Numerous showers and
storms producing pockets of sub-VFR conditions are expected Wed
through Thu night, mainly (but not exclusively) each aft/eve as a
cold front approaches then stalls over the region. This front is
expected to drift slightly E to along or E of I-95 Fri through the
weekend, keeping the best shower/storm chances over RWI/FAY,
although this could change with later forecasts. -GIH

...A LINE OF STRONG THUNDERSTORMS WILL AFFECT NORTHEASTERN MOORE...
HARNETT...NORTHWESTERN CUMBERLAND...LEE AND NORTHEASTERN HOKE
COUNTIES UNTIL 800 PM EDT...

At 653 PM EDT, Doppler radar was tracking a cluster of strong
thunderstorms along a line extending from near Carthage to 9 miles
south of Lillington. Movement was north at 15 mph.

Wind gusts up to 40 mph will be possible with these storms, along
with heavy rainfall and the threat for flooding.

Locations impacted include...
Fayetteville, Sanford, Southern Pines, Lillington, Carthage, Fort
Bragg, Pinehurst, Aberdeen, Angier and Pope AFB.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Seek shelter in a nearby building or vehicle. Wind gusts as high as
40 mph are capable of knocking down tree limbs and blowing around
trash cans, potted plants, lawn furniture and other light outdoor
objects.

Locally heavy rain will quickly reduce visibility and result in
ponding of water on roadways, standing water in low lying areas, and
minor flooding of creeks, streams, and areas of poor drainage.
Drivers are urged to slow down and use extra caution to avoid
hydroplaning, especially in urban areas where prolonged heavy rain
can quickly lead to flooding.
