Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
322 PM EDT WED JUL 13 2016
.SYNOPSIS...
Influence from a Bermuda high will keep the area in a typical
summertime pattern through Thursday. A weak cold front will approach
the southern Appalachians by Friday and stall through early next
week, generally enhancing rain and thunderstorm chances across the
forecast area.
&&
.NEAR TERM /THROUGH THURSDAY/...
At 230 PM Wednesday: Zonal upper flow was in place across most of
the CONUS this afternoon, and this pattern is expected to persist
into Thursday. A weak shortwave is expected to cross the southern
Appalachians this evening, perhaps followed by an even weaker one on
Thursday. Weak surface troughing is expected to persist over the
Carolinas and northeast Georgia through Thursday.
Although instability is present this afternoon, moisture is somewhat
limited, especially east of the mountains, and shear is rather weak,
limiting convective coverage and intensity. Instability and
moisture appear to be slightly greater on Thursday, mainly over the
mountains, improving convection chances and coverage slightly.
Temperatures will run above normal both tonight and tomorrow, with
heat index values between 100 and 102 in the upper Savannah River
Valley Thursday afternoon.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
As of 230 pm EDT Wednesday, troughiness extending from the Great
Lakes to the mid South will push east toward the southern
Appalachians on Friday. At the surface, a lee trough will develop as
the upper support arrives and likely west to solid chance PoPs for
convection will be supported by late day. A surface reflection may
form over the piedmont of the western Carolinas late Friday, and
this added forcing will likely keep scattered convection going well
into the nighttime hours Friday night/Saturday morning - especially
with upper divergence increasing as well. Consensus SBCAPE values of
2000 to 2500 J/kg look likely as 850 mb flow toggles more southerly
and there is less dewpoint mixing late Friday. Wind profiles will be
fairly weak up the column and organized severe is not likely, but
pulse to multicell isolated severe will be possible.
The trailing surface cold front will settle into the region and
stall on Saturday. This should lead to another day of fairly robust
coverage across the forecast area, but temperatures should be cooler
with more clouds.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
As of 200 PM Wednesday...the extended period begins 00Z Sunday with
a large, deep upper ridge setting up over the central plains and a
trough deepening over the eastern CONUS. At the surface, a weak
frontal boundary stalled across the southern Appalachians will
remain relatively stationary through the end of the extended period.
The combination of the upper trough, some upper diffluence over the
southeast, and the stalled boundary will enhance precip chances
through the middle of next week, though pops will remain diurnally
favored and generally higher over the higher terrain. The strong
upper ridge will continue to deepen over the central CONUS through
the middle of next week, but its influence on temps will remain
generally confined to the central plains, and max and min temps will
remain near or less than a category above normal.
&&
.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
At KCLT: VFR. Convective chances this afternoon are a bit too low to
mention. Overnight vsby restrictions remain northeast of the field.
Cigs, though not supported, would be low VFR. Winds will favor the
SW.
Elsewhere: Afternoon convective chances only reach levels warranting
a mention at KAVL, but foothills sites will be close. Vsby
restrictions will be limited to KAVL, but restrictions are expected to
the west of KHKY. Cigs are not favored, but would be low VFR in the
foothills and upper MVFR at KAVL if they occur. Winds will favor the
SW in the foothills, and NW at KAVL.
Outlook: Fairly typical midsummer weather with PM showers and
thunderstorms expected through Friday. A frontal boundary pushing
in this weekend will enhance the daily coverage thereof. Each day,
AM fog and low stratus will be possible in the mountain river
valleys and also in locations that receive heavy rainfall in the
preceding PM.
