Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
658 PM EST Thu Nov 15 2018
.SYNOPSIS...
Cool and dry high pressure moves over our region Friday behind a
departing cold front. The high remains in place for the weekend. A
couple of dry cold fronts cross the area on Monday then again on
Wednesday.
&&
.NEAR TERM /THROUGH FRIDAY/...
As of 2pm EST Thursday: Main brunt of precipitation with strong
upper system crossing through the central Eastern CONUS is past the
area, with precipitation having ended everywhere. Some light snow
is expected in the mountains and adjacent foothills tonight as low-
level upslope flow assists. Extensive cloud cover will gradually
improve overnight as low-level flow becomes more westerly to
northwesterly and Friday is expected to be mostly clear and warmer.
Currently northeasterly CAD surface flow is weakening as surface low
associated with the upper system becomes better defined east of the
area. On the backside of this low, surface winds are expected to
become westerly this evening. 850mb winds becomes quite strong
overnight as southside of system crosses over the region, with 850mb
winds up to 40kts. This might give some strong gusts at higher
elevations for awhile tonight, but diurnal stabilization of the
boundary layer should keep gusts isolated to higher elevations.
Do not expect significant problems from black ice as significant
snow or sleet did not accumulate today, though a few isolated
locations with some sleet that fails to melt this afternoon may see
some black ice, and will issue an SPS for that.
Flood watch will continue this afternoon as some rivers are still
high or rising from run-off from early rainfall.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
As of 140 PM EST Thursday: Zonal or low amplitude southwesterly flow
aloft develops behind the departing upper low Saturday and remains
in place on Sunday. Moderating surface high pressure builds in from
the west on Saturday and weakens on Sunday as a cold front
approaches from the west and a weak surface low develops along the
Carolina coast. The results of all this are diminishing winds and
mostly clear skies Saturday. Light winds continue Sunday but high
clouds increase late in the day as upper level moisture streams in
ahead of the two afore mentioned systems. Still, both days will be a
welcome respite from the weather earlier in the week. The only
potential weather concern is the possibility of morning fog both
days. Some guidance is hinting at widespread potentially dense fog
while others aren't as concerned. The ground will be very moist and
relatively warm with cool air temps. However, will leave out for now
given the discrepancies. Lows Saturday morning will be around 5
degrees below normal rising to near or just below normal Sunday
morning. Highs Saturday will be near or just below normal then
steady or a degree or so lower on Sunday.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
As of 215 PM EST Thursday: Expect the weather to generally be quiet
through the extended for a much welcomed break. A series of weak
short waves cross the area in a developing low amplitude eastern
trough. At the surface, a mainly dry cold front crosses the area
Monday. There may be enough moisture to wring out a few showers over
the TN border counties. However, temps will be warm enough for any
showers to be rain. Another dry cold front crosses the area
Wednesday with dry high pressure for Tuesday and Thursday. Highs
will be near normal Monday ahead of the front then remain around 5
degrees below normal through Thursday. Lows near normal Monday and
Tuesday mornings fall to a few degrees below normal for Wednesday and
Thursday mornings.
&&
.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
At KCLT and elsewhere: Cigs/vsbys expected to become VFR by 06Z
across main terminals as cold front pushes/mixes out lingering
low level moisture and associated low cigs. Gusty NW winds
behind the front expected across mountain sites through 08Z
including KAVL with a chance of briefly impacting KHKY.
Otherwise light winds and VFR conds should prevail for the
remainder of the TAF period as high pressure gradually filters
into the region from the west.
Outlook: VFR conds likely prevailing this weekend, except for the
potential IFR or lower cigs/vsbys during the late night to early
morning hours due to fog.
