.SYNOPSIS...
Below normal high temperatures stick around through next week. Dry
and cold high pressure remains in control through Saturday before a
cold front brings precipitation chances Sunday. Drier conditions
develop briefly Monday before a low pressure system from the Gulf
brings better precipitation chances Monday night and Tuesday. Dry
high pressure returns Wednesday into Thursday.

.NEAR TERM /THROUGH SATURDAY/...
As of 630 PM EST Friday...

Key Messages...

1) Lighter Winds Return this Evening

2) Tonight will be the Coldest Night of the Season

3) Cold and Dry with Well Below Normal Temperatures Again Saturday

Tonight, the center of high pressure passes just north of the area,
supporting favorable radiational cooling conditions. High clouds
will stream overhead, but they should have minimal impact on
temperatures. A cold airmass and ideal cooling conditions will set
the stage for the coldest night of the season thus far. Lows are
expected to fall into the teens across the mountains and the lower
to mid twenties across the Foothills and Piedmont.

High pressure shifts east on Saturday and moves toward the Mid
Atlantic coast, but it will continue to control our weather. A weak
southerly return flow develops by afternoon as warmer air begins to
approach from the southwest. However, the warm advection arrives
slowly, so highs on Saturday should be similar to today, mainly mid
to upper 40s outside the mountains with 30s at higher elevations. A
deep mixed layer should promote downward mixing of drier air again
on Saturday, allowing min RHs to fall near or below 30% across much
of the area. Lighter winds should limit fire weather concerns.

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
As of 11 am EST Friday:

Key message: Brief period of wintry precip remains possible in
portions of the mountains and possibly NW NC Piedmont late Saturday
night into Sunday morning ahead of a weak cold front.

SW flow remains progged to ramp up Saturday evening, along and
downstream of approaching weak baroclinic zone. 45 kt LLJ will
translate atop the cwfa after 06Z Sunday promoting stout winds
at higher elevations. Light pcpn should be initially forced by the
aforementioned LLJ, and the resultant diabatic cooling toward
critical wet bulb temperatures will give rise to the chances for
pockets of freezing rain to develop (after a token frozen
pcpn chance on onset) mainly in the mountains by early Sunday
morning.  Given the transient nature of the parent sfc hipres
and overall light nature of the pcpn, by the time precip becomes
more likely during the day Sunday, temps in most areas should be
able to warm above freezing.  With the frontolytic nature of the
cold front, numerous showers Sunday morning will give way to
diminishing chances in the afternoon.

Sfc ridging looks to reassert itself on Monday with a CAD regime
seeming more likely to develop by the end of the day.  We will be
watching for the likelihood of western gulf cyclogenesis on Monday
and the quick return of SW flow and moisture into the Southern
Appalachians. Thicker cloudiness remains fcst to overspread the
cwfa, and in concert with chilly NE sfc flow, maximum temperatures
will be 8-10 Deg F below the December 1st normal.

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
As of 1130 am EST Friday:

Key message 1: Precipitation redeveloping by Monday night. There
remains the threat of a period of wintry weather for the NC
mountains/foothills and NW NC Piedmont.  Rain tapers off Tuesday
afternoon, perhaps ending as a period of snow in the high mountains.

Ongoing high likelihood that the region will receive a round of
briefly heavy precipitation at some point late Monday night and/or
Tuesday as deepening Miller type A low affects the Southern
Appalachians. Based on the 28/12Z NBM, The NC mountains northeast of
the French Broad Valley, and parts of the NC Piedmont along and
north of I-40 remain the locations where the better chances exist
for a period of of wintry mix, with the highest p-type probability
being fzra.

Dry-slot looks to punch through before 00z Wednesday bringing a fast
end to widespread pcpn although cooling temps within the TN border
counties will support a transition to snow showers there on the back
side of the system.

Key message 2: Dry high pressure should return by late Tuesday
night, with daytime temps trending milder Wed and Thu.  Perhaps next
round of rain will be on Friday.

Sunshine returns on Wednesday as high pressure builds atop the
region with moderating return flow developing Thursday.  Gulf
moisture tap may return pcpn to the region on Friday.

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
At KCLT and elsewhere: VFR and dry with lighter winds expected
through the 00Z TAF period. Cirrus will periodically increase at
times over the terminals through the period ranging anywhere from
FEW to BKN. Winds will start out NW at KAVL, becoming VRB overnight
into daybreak Saturday before toggling SE by the early to mid-
morning hours Saturday. Winds elsewhere will generally range from
WNW/NW this evening, gradually turning more NE overnight then
turning more E/ESE by mid-morning to late morning Saturday.

Outlook: Restrictions and rain chances return Sunday before dry and
VFR conditions briefly return Monday. Another round of rain and
restrictions are expected Tuesday before dry and mainly VFR
conditions return Wednesday into Thursday.
