Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
445 PM EDT THU MAY 12 2016

.SYNOPSIS...
A cold front will move into the southern Appalachians from the west
tonight and then move east across the piedmont of the Carolinas on
Friday. Drier air will spill into the region Friday afternoon into
Saturday. A reinforcing cold front arriving from the northwest
Saturday night will bring even cooler and drier high pressure to the
area Sunday into Monday. Moist southerly flow will return through
mid week along with steadily increasing shower and thunderstorm
chances.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 4:35 pm EDT Thursday: Scattered showers and thunderstorms
currently across the region, more numerous in the mountains, will
continue through this evening.  Activity has seen hail to 1 inch and
some severe wind gusts, with more such low-end severe reports likely
this evening.  Activity will transition from thunderstorms to
showers overnight as surface cooling reduces convective
instability.  Showers will end from northwest to southeast Friday
morning through afternoon as a major cold front passes through the
region.  Cold frontal passage will veer wind to northwesterly and
dry and cool the region, bringing temperatures back down to near
normal on Friday.

The cold front will slowly cross the foothills and piedmont portions
of the forecast area Friday morning. Upper jet divergence and one
final shot of upper level DPVA will also cross the forecast area
Friday morning and this upper support may catch up to the
pre-frontal instability along and east of I-77 by late morning. Will
bring back thunder chances across these areas through at least Noon
or perhaps into the early afternoon. West to northwest flow and
strong deep layer drying will develop behind the front through late
Friday. Breezy conditions are likely in the mountains post fropa
Friday as a narrow window of cold advection overlaps mixing.
However, winds should remain below advisory criteria. Max temps will
be a couple of categories cooler than today.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
As of 200 PM Thursday...This upcoming weekend looks relatively quiet
and seasonably cool, as a long wave upper trough digs across the
eastern CONUS. A reinforcing cold front will approach the area from
the NW on Saturday, with dry WLY flow ahead of it. Other than a few
upslope showers near the TN border, expect dry wx for the region.
Temps will be near normal in the mtns and a category above in the
piedmont.

Significantly lower thicknesses will spill in from the NW for
Sunday, resulting in slightly below normal temps. Breezy to windy
conditions are expected in the mtns from Saturday afternoon into
Sunday within decent 850 mb CAA.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
As of 230 PM Thursday...the eastern CONUS upper trough will lift NE
on Monday, allowing upper ridging to begin across the Southeast. The
upper pattern remains somewhat flat thru much of next week, but with
general troughing over the west and ridging along the East Coast. At
the surface, high pressure will slide off the Mid-Atlantic coast on
Monday, while a low pressure system tries to organize over the
Southern Plains. The medium range guidance generally agrees on a
warm front, extending east of the low, activating across the Gulf
states, while a weak wedge lingers across the Carolinas. This should
set up a more unsettled wx pattern for the CWFA, with max temps
returning to near normal and min temps above normal by the middle of
next week.

&&

.AVIATION /21Z THURSDAY THROUGH TUESDAY/...
At KCLT, radar coverage remains fairly sparse around the airfield
but LAPS CAPE values of 1500 to 2000 J/kg indicate that the airmass
is primed for convection with any nearby triggering
boundaries/outflows. Will keep TEMPO TSRA timed mainly 19Z to 23Z at
this point but another round of convection could arrive later this
evening with activity developing from northern GA to eastern TN. A
third round of showers and thunderstorms may reach the Interstate 77
corridor late tonight but with a weakening trend given the more
limited nocturnal instability. Finally, upper level support may
catch up to the passing front by Noon on Friday to generate one last
round of scattered SHRA/TSRA with fropa. Anticipate mainly S to SW
winds for much of the period, but with winds toggling NW late in the
period with fropa.

Elsewhere, thunderstorms triggering along the Blue Ridge will keep
TEMPO TSRA going at KAVL for a few hours past issuance time.
Development should hold off until around 19Z at most of the foothill
sites and TEMPOs timed 19Z to 23Z appear about right for these
locations. Another round of convection may arrive from the west
through the evening hours with yet another round of weakening
SHRA/TSRA possible overnight just ahead of the approaching cold
front. MVFR conditions will be limited mainly to the heaviest
downpours and also possible at KAVL and KHKY early Friday with
better low level moisture. Expect a drying trend with a sharp
northwesterly wind shift Friday morning. Gusts of 20 to 25 kt are
likely at KAVL Friday morning with mixing and cold advection.

Outlook: A cold front will move east of the area Friday afternoon
with drying expected through Saturday. A reinforcing cold front will
cross the region Saturday night with cooler and drier conditions
expected Sunday through Monday. Southerly flow and moisture will get
slowly reestablished through the middle of next week. Diurnal
thunderstorms will become possible again - especially over the
mountains.
