.DISCUSSION...
As of 107 PM Friday...

KEY MESSAGE 1... Continued light patchy rain through this evening.
Overcast with patchy dense fog possible tonight.

The sfc cold front remains stalled to our south this afternoon while
cooler, saturated nely flow remains locked in over central NC. The
steadier rain has moved well east of the Coastal Plain at this point
following the exit of a lead vorticity perturbation. The strong
short-wave/vort max has dug deep into GA/AL this afternoon, largely
directing convection to our south into FL. Any lingering light
patchy drizzle/rain over the area should dissipate with time through
this evening. Otherwise, overcast conditions are expected again
tonight for much of central NC with warm overnight lows lower to mid
40s. Similar to this morning, expect reduced visibility largely from
elevated fog (lowered stratus) with perhaps some locally dense fog
possible in areas. Best signal for dense fog appears to possibly be
in the Foothills/Western Piedmont where some thinning of the clouds
may result in radiational fog.

KEY MESSAGE 2... Low probability of wintry mix Mon into Tues morning
in the Piedmont, but predominant precip type, and amounts remain
uncertain.

Developing moist isentropic ascent atop the shallow sloped low/mid-
level frontal boundary is expected to support light stratiform rain
over the Mid-Atlantic, but timing and southern extent of the
precipitation footprint remains uncertain and highly dependent on
the evolution of mesoscale features (position and strength of 925-
850mb WAA/FGEN). The EPS has been consistently the northern most
solution with precipitation directed over the Virginias, although
its AIFS counterpart has shift slightly south compared to model runs
from 12z Thurs. The GEPS/GEFS/AIGFS-ensemble remain farther south
and paint highest probabilities of > 0.1" across the NC/VA border.
Best chances will likely be along and north of the I-85 corridor
into the northern Coastal Plain.

Using top-down and nomogram techniques for expected p-type, the
overwhelming model consensus is that the 850-700mb layer is expected
to remain > 155dam over NC and likely will not support anything
other than sleet, freezing rain, or cold rain. The surface wet-bulb
zero line and strength of the warm nose will likely determine
predominant p-type over our area. Unfortunately, predictability in
these variables remains low for our area at this time to say much
with any degree of certainty.

Most likely scenario: Minimal amounts of liquid equivalent with most
places only achieving trace amounts to 0.05". Light rain and
conversational onset of some sleet Mon afternoon/evening ends as a
cold light rain with surface temperatures above freezing throughout
Mon night into Tues morning. No hazardous weather or impacts to
travel expected.

Worst-case scenario (5-10% chance): Onset of pure sleet Mon
afternoon/evening results in very light sleet accumulation (abated a
bit by warm ground and above freezing surface temps) transitions to
light freezing rain after sunset when surface wet-bulb temps drop
below freezing. Even in this scenario freezing rain accrual will
almost certainly be less efficient than a 1:1 ratio since air temps
will likely be > 28 degrees. Minor impacts to travel for Tues
morning commute would be possible due to a light/thin glaze on
elevated surfaces and bridges.

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
As of 710 PM Friday...

Confidence is high in poor aviation conditions dominating at all
central NC terminals through at least mid morning Sat. A frontal
zone has settled to our S, with cool high pressure nosing into NC
from the N and NE. While patchy MVFR cigs have dipped into far north-
central NC in the last few hours, the cool flow combined with moist
air in the low levels will bring a continued high threat for
IFR/LIFR cigs at central NC terminals tonight through mid morning.
Vsbys are expected to drop to MVFR prior to 05z and to IFR and
perhaps LIFR overnight until returning to mainly MVFR by around 12z-
13z. LIFR/IFR cigs are likely to hold until around 14z-16z N and 16-
19z S, when cigs are expected to rise to MVFR for an hour or two
before becoming VFR as clouds scour out from N to S. Confidence is
high that VFR conditions will return by 19z at northern terminals
(INT/GSO/RDU/RWI) by 21z S (FAY). Surface winds will be light, under
8 kts, and variable or from the NNE and N through Sat.

Looking beyond 00z Sun, VFR conditions should hold through Sat
evening, but sub-VFR vsbys in fog are possible late Sat night
through Sun mid morning, especially over the S and E (RWI/FAY most
likely to be affected). Starting Sun evening, another weather system
will bring low gray clouds and a high chance for sub-VFR conditions,
lasting into Tue. And cold rain or drizzle, perhaps mixed at times
with sleet, is likely Mon/Mon night. Brisk/gusty winds from the NE
are possible Sun evening through at least Mon morning.
