Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
258 PM EDT Thu Jul 6 2017

.SYNOPSIS...
Seasonable temperatures and mainly afternoon showers and
thunderstorms will continue through Saturday. A front will push
through the area Saturday night, bringing somewhat drier and cooler
air for Sunday and Monday. More humid and unsettled weather are
expected by Tuesday as that front creeps back into the area from
the south.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 245 PM: Scattered showers and thunderstorms continue to
develop over the mtns/foothills and back across n Georgia and ern
TN. Area east of the Blue Ridge seems primed for another round
of scattered strong/severe storms again this afternoon/early eve,
with sbCAPE on the order of 2500-3500 J/kg. Similar to yesterday,
we should have another excellent downburst environment with mid
level dry air and dCAPE greater than 800 J/kg. Expect a few severe
storms with wind damage the primary threat. The shear is a bit
stronger today, so it will be interesting to see if the storms
can get better organized along cool pools.

Otherwise...the pattern remains persistent, although slowly
progressive, so a refresher on what happened the last few nights
just to our west is instructive. Each night, nocturnal convection
has developed closer to the trof axis, and that seems reasonable
tonight, but with the activity shifted shifted eastward by a
few hundred miles and over the NC mtns. So, after the convective
activity wanes later this evening, have kept a chance of precip
across the NC zones through the overnight hours. On Monday, the
trof axis should move slowly east across the fcst area with the
main short wave moving overhead in the afternoon. The fcst reflects
this with a chance of precip shifting east during the morning and
then to the south in the afternoon. Severe weather chances not as
good as the last few days with better dCAPE kept to the south.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
As of 130 PM Thursday: a long wave trough axis will set up roughly
along the Appalachians for Saturday and Sunday. This should be far
enough east to allow a cold front to push completely thru the CWFA
and usher in some drier, more stable air into the area. The 12z
model consensus looks a bit drier overall than previous runs,
depicting a 1020 mb high building across the Ohio Valley. Saturday
should see at least some isolated showers and tstms as the front
pushes thru and dry air slowly works in from the NW, but moisture
convergence looks weak. By Sunday morning, conditions should be dry.
Temps will be near to slightly above normal Saturday and near to
slightly below normal (with noticeably less humidity) on Sunday.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
As of 150 PM Thu: The stalled out front to our south will begin to
drift north Sunday night into Monday which will slowly increase
moisture over southern areas at first. Weak high pressure will
remain over much of western North Carolina through Monday.  A
shortwave crossing the Great Lakes Monday night and Tuesday will
have an associated weak cold front moving southeast which may help
to initiate convection for areas north of I-40 by Tuesday evening.
This front to our north will become stationary or nearly so
remaining near the northern parts of WV and VA going into late week.
Upper support for the front moving south will be minimal  We will be
in a typical summer pattern of diurnal chances of afternoon and
evening showers and storms.

After weekend Min Temps being near or a little below normal, all Mas
and Mins through the rest of the medium range should be near steady
state normal.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
At KCLT: VFR stratocu early this afternoon across the Piedmont
will eventually develop and give way to showers/storms developing
to the west. The situation is persistent, lending creedence to the
idea that another round of TSRA will move across or at least very
near the air field later today, in spite of the differences in the
convection-allowing model guidance. Thus, have opted for a TEMPO for
TSRA in the 21Z-01Z time frame. Environment is supportive of strong
downbursts, so gusty winds are expected near any storms. Showers
should linger into the mid evening, followed by convective debris
cloudiness overnight. The upper trof will be closer to our region
Friday morning, suggesting a better chance for precip on Friday
morning as has been seen off to the west the last few mornings. This
possibility will not be included in the fcst at this time, instead
have opted to bring the chance in at 15Z with morning heating. Wind
should stay SW when not influenced by thunderstorm outflows.

Elsewhere: Again, a persistence forecast, and similar to KCLT. Will
attempt to get the timing for storms in the late afternoon/early
evening. Nocturnal convection a better possibility over the mtns,
but will keep the chances down in the 30 pct range. KAVL and KHKY
also have the best chance of seeing any restrictions overnight.

Outlook: Moist and unsettled weather will continue through Saturday.
Thunderstorms may become more numerous Friday as an upper wave
passes followed by a cold front. Nocturnal restrictions can be
expected in any locations receiving heavy rainfall, and also in
the mountain valleys. Some drying is indicated by Sunday into
early next week.
