Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
242 PM EDT Thu Jun 14 2018

.SYNOPSIS...
A weak cold front will settle southward into the region tonight and
then stall across the area on Friday. Slightly drier and more stable
air will work into the region from the north through Friday, but
summertime heat, humidity, and afternoon storms will return over the
weekend. Much of next week will remain very hot, with scattered
afternoon and evening thunderstorms.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 225 PM Thursday...We are just starting to see a few cells
develop over the higher terrain, although they have not produced any
lightning yet. I still expect convective coverage to increase over
the next several hours. Otherwise, a weak ulvl trof will traverse
the region tonight with the best forcing remaining south and west of
the fcst area. Meanwhile...sfc high pressure behind the trof will
push a frontal zone farther south thru the evening. The CAMS have
been inconsistent so far today wrt the coverage and timing of
convective development and currently have the best coverage over the
NC Foothills and Piedmont. PoPs were raised a bit over this area and
lowered a bit over the higher terrain. With very low shear and
sbCAPE peaking around 2000 J/kg, still thinking a few cells could
become severe. Isolated showers may linger into the overnight period
with no significant impacts as they dissipate thru 06z or so. Max
temps will peak above climatology today and again tomorrow.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
As of 215 PM Thursday: A robust upper-level ridge axis will begin to
build in earnest from the Mississippi River Valley region to the
western Carolinas over the weekend. This will herald the onset of
much warmer than climo temperatures, with the heat increasing
further into next week. At the surface, any lingering stalled
frontal boundary will dissipate, with a persistent piedmont trough
embedded within developing surface high pressure across the
southeast through the weekend. This will lead to a diurnal pattern
of scattered afternoon and evening thunderstorms Saturday and
Sunday, with generally a mountain ridge top maximum to the coverage.
Expect plenty of mid 90s for Sunday afternoon highs east of the
mountains, but with Heat Index values remaining below the Advisory
criteria of 105.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
As of 225 PM Thursday: A strong 500 mb ridge, with H5 heights in the
592 to 594 dm range, will persist over the southeast at least
through Monday. The GFS has some hints of northern stream energy
starting to break down the ridge on Tuesday, but the ECMWF
stubbornly keeps a flatter 590 dm ridge in place until early
Wednesday. There is better consensus on deep layer northwest flow,
and a possible setup of MCS tracks from the northwest, on Thursday,
along with slightly cooler temperatures. Until then, expect
scattered diurnal convection to continue Monday through Wednesday
with maximum temperatures about 5 to 10 degrees above climatology in
most areas. A few piedmont locations could teeter on Heat Advisory
criteria if dewpoints do not mix out during the afternoons.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
At KCLT and elsewhere: Expect mostly VFR conditions thru the 18z TAF
period. So far today we have yet to see any convective activity,
although some thunderstorms have developed well to our SE. We are
still expecting convection to develop over the fcst area during the
next few hours, but coverage could be more limited than previously
expected. As such, I included VCTS into the evening for all sites
except KCLT, where I have VCSH and a TEMPO for TSRA from 19 to 23z
with some vrb wind gusts. The only restrictions I included were for
KAVL for MVFR visby beginning around 08z tomorrow with a TEMPO for
IFR visby and cigs from 09 to 13z. Winds will remain light and
generally WLY thru the evening, before becoming NLY late tonight and
into the overnight. By the early afternoon tomorrow, they will
likely veer around to more NELY.

Outlook: Into the weekend, typical summertime potential for showers
and thunderstorms will be possible each day in the afternoon and
evening, along with morning fog in the mountain valleys and over
lakes.
