What forecasters said that day

The local office's own words before this wind advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before this wind advisory went out at Dec 16, 3:35 AM EST, 8 minutes earlier.

Area forecast discussion, Dec 16, 3:35 AM EST, 8 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
335 AM EST Fri Dec 16 2016

.SYNOPSIS...
Strong Canadian high pressure will remain over the region and hold
temperatures below normal into Saturday. A moist cold front is
expected to push through Sunday and stall out south of the forecast
area through the early part of next week. Dry high pressure returns
late Tuesday.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 330 AM EST Friday:  Cold high pressure will consume the region
today, beneath confluent flow aloft.  Said ridge will migrate east
through the day, moving atop the Delmarva by later this evening
all the while wedging southward in the lee of the southern/central
Appalachians across the Carolinas into northeast GA.  Meanwhile to
the west, a weak upper disturbance will promote surface cyclogenesis
across the Central Plains, eventually moving east toward the mid
MS river valley by periods end.  As such, guidance continues to
favor temperatures today nearly 15-20 degrees below normal as a
combination of the cooler airmass and increasing sky cover thanks
to downstream advection of mid/high clouds from the upstream
disturbance.

The fcst will remain dry through 00z before slight/chance pops are
introduced from the south as moist upglide atop the cold wedge
commences into late evening/overnight.  This precipitation will
likely initiate as light rain, changing to freezing rain/drizzle
as temperatures fall off to near/below freezing.  That said,
there remains some uncertainty in the fcst as it pertains to
these critical temperatures and how they relate to timing of
precipitation onset, as well as warming trends into the daylight
hours on Saturday morning.  Nevertheless, the latest guidance
does yield light icing across portions of northeast GA and the SC
Upstate, northward into western NC, with ice accumulations less than
five hundredths of an inch.  Given these lower accumulations, and a
slight warming trend in the guidance, will defer any fzra advisory
issuance to the day shift and newer 12z guidance.  Furthermore,
a rather robust swly llv jet will move into the region overnight
tonight ahead of the approaching cold front.  Latest Nam12/GFS20
favor advisory level winds across the higher elevations of the
southern mtns, generally above 3500ft.  Therefore, will issue a
high elevation wind advisory starting at 00z tonight for these
locales, where gusts nearing 50mph will be possible.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
As of 320 AM Friday, guidance and overall pattern in good agreement
on Saturday. Light precip will continue through the day, but with
better chances over the SC/GA Blue Ridge and the SW NC Mountains.
With the cold surface air over the NC Blue Ridge and Piedmont, light
freezing rain may be continuing at the start of the day, but will
quickly change to rain as temps warm. With light precip and quick
changeover, any additional ice accretion would be very light. Even
with the warming temps during the day, highs will still show an
in-situ damming pattern with warmer temps along the TN border and
south of I-85, with cooler temps along and east of the Blue Ridge.

A cold front will move east to the NC/TN border Saturday night then
swing across the area Sunday. Expect temps to warm through the night
in the increasing SW flow and WAA. Precip chances will remain highest
over the mountains Saturday night then spread east on Sunday. There
is good forcing and moisture inflow with this front, so moderate QPF
amounts are forecast. Shear will be strong, but instability will be
low. Cannot rule out some thunder south of I-85. There is even a
non-zero severe weather chance over that area, but not enough to
mention yet in the HWO. Highs will be above normal Sunday.

Precip moves east of the area Sunday night with the cold front. Cold
air will move in across the area behind the front. Lows across the
mountains will be near normal, but a little above normal elsewhere.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
As of 220 AM EST Friday: The ulvl flow remains aligned sw/ly thru a
deep layer to begin the ext range. This will hold a sta front south
of the CWFA and keep the best chances of precip across the srn zones
with continuous moist GOM flow in the sfc-h85 layer. A weak h5 s/w
crosses the Midwest Tue disrupting the downstream pattern and heights
rise slightly while becoming less defined over the region. In
response...an elongated sfc high will settle south over the SE
region and aide in clearing skies and reducing the pop potential to
nil Tues night thru the day Wed. The op models have varying ideas
with the height pattern and degree of deep subs...but the overall
drier pattern has good confidence.

There are more sigfnt differences wrt the synoptic pattern Thu/Fri
as a stronger h5 trof digs across the mid-conus. The GFS is much
deeper and farther south than the ECMWF with the trof axis...which
allows for better moisture flux to a weak low pressure area and an
increased qpf response with a late period fropa. In any regard...it
should be a quickly passing and stable system with rather low-end
precipitation. Temp curves each morning will support diurnally
induced -snsh or a -ra/sn mix mainly over the nrn half of the CWFA
with no measurable accums expected. Maxes will begin the period arnd
10 degrees below normal and modify to seasonal levels by end of the
period.

&&

.AVIATION /09Z FRIDAY THROUGH TUESDAY/...
At KCLT and elsewhere:  VFR through the vast majority of the taf
cycle as high pressure migrates across the southern Appalachians,
eventually taking root atop the Mid Atlantic coastline all the while
wedging south in lee of the mountains.  In the meantime, quasizonal
flow will advect moisture downstream of a Rockies disturbance,
yielding mid/high clouds through much of the day on Friday.
Llv moisture will begin to spread in from south late on Friday as
the Rockies system slides east yielding sw flow and thus increasing
upglide atop the wedged high.  With that, included mention of
precipitation late at all sites, likely as ra changing to fzra as
wetbulbing and diurnal cooling yield subfreezing surface temps.
Cigs will lower in compliance with the increasing precipitation
potential into late evening/overnight from low VFR to MVFR.
Winds are fcst to remain nely tonight, veering sely through much
of the day Friday, before backing nely yet again late in the taf
cycle as precipitation commences and thus strengthens the surface
wedge pattern.  LLWS was included at KAVL on Friday night as llv
winds increase out of the sw atop weak ely surface flow.

Outlook: Sufficient moisture will linger about the region
through Saturday to keep chances for restrictions elevated,
then into/through Sunday as cold front pushes through.  Dry high
pressure will return to start the week leading to lower chances
for restrictions.
