.DISCUSSION...
KEY MESSAGE 1...Current analysis this morning depicts a complex
mid-level pattern with three distinct shortwaves digging across
portions of the Great Lakes, Midwest and MS Valley while primary
jet axis sits just to their east over the spine of the
Appalachians. At the surface, main feature of interest for us
is a stalled to slow moving front sitting across far western NC
which is just now beginning to push eastward. Pre-frontal
trough ahead of it is driving a broken band of showers and a few
embedded thunderstorms extending roughly along the I-85
corridor.

The forecast for today has changed little, with widespread
showers and a few thunderstorms developing late this afternoon
as the aforementioned front finally makes its way through our
area. Most CAMs continue to depict some isolated showers
migrating NEward off the water along the pre-frontal trough.
This is certainly possible although it is worth noting this is a
common artifact in guidance that has a very mixed history of
being realized. If such activity does develop, it could modestly
hamper destabilization through the day. In either scenario, a
minimum of around 500 J/kg MLCAPE (worst case scenario 1000 J/kg
as suggested by the HRRR) to be in place this afternoon across
the region fueled by above average moisture and temperatures in
the mid to upper 70s. This is unusually high for early November,
supported by EFI highlighting CAPE values in the 75-80th
percentile.

In addition to instability, respectable low-level shear will be
present ahead of the front with 0-1 km values potentially
reaching 20-25 kt. This will support a pre-storm environment
that could support organized convection and possibly low-topped
supercells in the afternoon and evening hours. The primary
hazard would be damaging winds, but model hodographs do show
low-level veering suggesting a brief tornado is not implausible.

The main threat window runs from early afternoon to around
sunset inland, lingering slightly longer over the Outer Banks
but with a diminishing severe risk as instability collapses. The
main front sweeps offshore late tonight with any remaining
showers exiting the OBX around or shortly after midnight. There
will likely be a delay between the main front coming through and
the dry air surge, so would not be surprised to see a period of
low stratus Fri night into Sat morning.

KEY MESSAGE 2...A more seasonably dry airmass will be ushered
in for the weekend behind the front. Expect a return to mostly
sunny skies and highs in the upper 60s to low 70s Sat, then
cooler yet for Sun with 60-65. Lows will be in the 40s, with
some 30s for some of the normally colder spots. We will have to
monitor the temp forecast for any frost concerns Sunday morning.

.AVIATION /12Z FRIDAY THROUGH TUESDAY/...
Forecast confidence is moderate over the next 24 hours.

A strengthening cold front will move east across central and eastern
NC today, eventually moving offshore by tonight. Scattered SHRA and
TSRA will accompany the front, some of which could produce wind
gusts in excess of 40kt. There will also be a risk of significant
reductions to VIS (LIFR/IFR). While not likely, a low-end tornado
risk is present as well, mainly for inland TAF sites. Ahead of the
front and TSRA, gradient/mixing winds will be capable of gusts up to
20-25kt out of the south.

The most uncertain part of the forecast is CIGs. CIG heights have
varied between 2500ft and 8000ft this morning, and this will
probably continue until the front gets closer. At that point, CIGs
should fall into the 2500ft to 4000ft range. In the wake of the cold
front, guidance insists on a period of low CIGs due to residual low-
level moisture. During this time, CIGs may fall as low as IFR/LIFR
for several hours.

Outlook: An extended period of VFR conditions is expected after
today`s TSRA as a much drier airmass builds in across the region.

&&

.MARINE...
Light to moderate southerly winds will continue through the
period (strongest across the outer southern and central waters).
Seas will persist at 3-5 ft nearshore and near 4-6 ft offshore
through today. A cold front moves through this evening into the
overnight hours for our waters, and ahead of this boundary
strong thunderstorms capable of gusty winds and a brief
waterspout are possible. Behind the front, winds switch to the
north/northwest, gusting to near 20 knots. Gusts exceeding 25 kt
will likely be concentrated beyond 20nm offshore, so no
headlines were offered this morning.

Outlook (Saturday through Tuesday): High builds in this weekend
into next week, keeping winds below 20 kts and skies rain-free.
Despite the decrease in winds, elevated seas may linger through
the weekend for 20-60nm zones at around 4-6 feet, and an
isolated 6 foot wave is possible just within 20nm primarily for
waters in Raleigh Bay.
