AREA FORECAST DISCUSSION
National Weather Service Raleigh NC
830 PM EDT Mon Jun 14 2021

.SYNOPSIS...
A pre-frontal trough will be located over central NC tonight. A cold
front will push southeastward through the area late tonight through
Tuesday morning, as an upper level trough shifts over the Mid
Atlantic coast. This front will slow down before stalling over
coastal North Carolina through mid week, as high pressure otherwise
builds in from the northwest.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 830 PM Monday...

Isolated to scattered pre-frontal convection is still favored across
the Southern Piedmont, Sandhills, and SE Coastal Plain through late
evening. There continued to be enough instability and moisture
convergence to generate isolated convection, but the lack of mid
level moisture has been a negative. Downdraft CAPE continues 1300+
around Fayetteville, thus any of these showers/iso thunderstorms
will likely produce gusty winds to 40 mph or so.

Regarding the severe threat, SPC had much of central NC in a
marginal risk for severe storms. It appears the lack of any
organization of the storms has led to sub-severe over our region.
Expect the threat to continue to diminish with increasing CINH.

Otherwise, skies should become mostly clear with lows in the 65-70
range.

Previous valid discussion issued at 300 PM Monday...

As far as the tropics are concerned, satellite and radar has shown
the low pressure system off the NC coast has become organized enough
to become a tropical depression as of 11 AM. It is expected to
become a tropical storm tonight, but it is quickly moving
northeastward and this will continue as it gets pushed out to sea by
a large upper trough that will be digging over the Eastern US. Thus
no impacts are expected from this system for central NC.

&&

.SHORT TERM /TUESDAY AND TUESDAY NIGHT/...
As of 400 PM Monday...

The cold front will remain near the NC coast tomorrow, with the
aforementioned mid-level shortwave trough moving across central NC.
Resulting deep-layer shear will be impressive, with 500 mb winds of
35-45 kts, but moisture and instability will be marginal at best.
Thus only have slight to low chance POPs in the far SE (essentially
Cumberland, Sampson, and Wayne counties) in the afternoon and
evening. Highs will range from the lower-80s in the far north to
near 90 in the far south. The biggest change behind the front will
be the much drier dew points, generally in the 50s, thanks to NW
downslope flow. Mostly clear skies and diminishing winds will help
bring temperatures down into the upper-50s to mid-60s on Tuesday
night with good radiational cooling.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
As of 300 PM Monday...

A high amplitude long wave trough over the Eastern US, featuring
negative H5 anomalies on the order of 2 S.D. below normal, will
drift slowly east, off the Eastern Seaboard late Thursday/Thursday
night. At the sfc, a wavy, stationary frontal zone will remain
draped across across the SE US as weak high pressure holds over NC.

While shortwave energy diving SE through the base of the upper
trough will likely result in a period of scattered to broken mid-
level cloudiness across central NC Wednesday and Wednesday night,
it's look increasingly drier across the area, with any convective re-
develop mostly likely remaining along the immediate coast. Instead,
under the influence of deep NWLY flow aloft, the airmass in place
across central will become increasingly drier, with PWATS decreasing
to 0.5-0.75" by Thursday. Furthermore, this downslope component,
aided by deep daytime mixing(8-10kft) will allow BL dewpoints to mix
out into the 40s and 50s Wednesday and again Thursday afternoon,
resulting in comfortable humidity levels as Highs top out in the
lower to mid 80s. Lows in the upper 50s and 60s.

Increasing heights/warming aloft in the wake of the exiting Eastern
US trough combined with the onset of southerly return flow will mark
a return to more summer-like heat and humidity starting on Friday,
with temperatures likely topping out into the lower to mid 90s over
the weekend. The cold front that models once suggested would move
into the area over the weekend now appears that it will remain north
of the area, keeping central NC in the warm sector. Keeping this
cold front north of the area would limit rain chances.
However, rain chances by late weekend and into early next weekend
could be more closely tied to the possible tropical remnants of the
broad low pressure area, currently over the Bay of Campeche and it's
tropical moisture feed into the SE US. Will continue to monitor, but
for now will advertise low chance PoPs.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
As of 730 PM Monday...

24-hour TAF period: Mainly VFR conditions are expected across
central NC through the next 24 hours. The only exception continues
to be the isolated thunderstorms this evening, mainly from near
Charlotte to Fayetteville. Gusty winds over 40 mph and brief sub-VFR
conditions are possible with any storm, and continue to highlight
the possibility with vicinity thunder at KFAY through mid-evening.
Any convection will diminish by around midnight. Winds will be light
from the SW today, shifting to the NNW late tonight and early
Tuesday morning as a cold front moves through. NNW winds may gust as
high as 15-20 kts behind the front Tuesday morning.

Looking beyond 00z Wed: The cold front will bring dry weather to the
region on Tuesday, except in the far SE including FAY where an
isolated shower or storm (and associated brief sub-VFR conditions)
can't be ruled out. Dry weather and VFR conditions are expected
everywhere from Wednesday through Friday. There is a slight chance
of showers and storms on Saturday as the next cold front approaches
from the NW.
