Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
1108 AM EDT Thu Jun 20 2019
.SYNOPSIS...
Today should be an active day with a risk of severe thunderstorms
developing by the afternoon ahead of a cold front, especially east
of the mountains. The passage of the front should give us a break
on Friday, but showers and thunderstorms will return over the
weekend. Temperatures and humidity will be typical of summertime.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 1050 am EDT: Conditions appear favorable for the
development of strong to severe thunderstorms across the region
this afternoon. The morning MCS remnants dissipated rather
quickly, and intermittent sunshine has permitted temperatures to
rebound quickly into the 80s while southwest flow has held dew
points in the upper 60s to lower 70s. A more prominent 500 mb
shortwave will arrive soon from the southwest and this is
already driving weak convection from AL/GA to central TN. This
forcing, along with improving upper jet divergence, should cross
the forecast area during peak heating. Wind shear has never
been much of a question, with surface to 3 km bulk shear values
easily reaching 40 to 45 kt as the mid-level speed maximum
arrives. Instability is bubbling back up on the LAPS sbCAPE
analysis with some 1500 to 2500 J/kg already indicated east of
the mountains. Additional modest recovery is expected this
afternoon despite the fact that the models aren't terribly
excited about the instability given slightly warm profiles.
Following the HREF trends, convection should fire early this
afternoon over the mountains, transition quickly across the
foothills and impact Piedmont sections through late afternoon or
early evening. Damaging winds appear to be the primary hazard
with strong, straight line hodographs and intense winds from 3
km upward, but lee troughing will also provide some backing of
the surface winds to keep an isolated tornado threat going. A
Severe Thunderstorm Watch may be needed this afternoon,
especially east of the mountains.
Showers may linger in NW flow across the western mountains for much
of the night, but any convective activity will race quickly east to
the coast with the upper support. Brisk gradient winds will
continue, but with gusts staying below advisory levels at all but
the highest peaks.
&&
.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
As of 324 AM EDT Thursday: The end of the work week still looks
quiet in the wake of a weakening sfc front. The chances for any
shower activity will be minimal as a drier air mass moves through
in the afternoon. Stronger westerly flow will allow high temps
to climb into the lower 90s in some places east of the mtns. The
weather situation gets mildly interesting from Friday night into
Saturday, though. The old boundary will effectively get left behind
running NW to SE that leaves a moisture gradient somewhere across
the srn Appalachians and southeast. The guidance continues to hint
at an MCS coming over the top of an upper ridge axis located over
the MS Valley region on Friday night and then rolling down toward
the Carolinas. The track of any remnant will go a long way to
determining what our chances for strong to severe thunderstorms
might be for Saturday afternoon. Right now, the guidance has
the gradient cutting our fcst area in half, with the NW Piedmont
remaining relatively stable and northeast GA becoming very unstable
(CAPE on the order of 3000 to 4000 J/kg). Have no qualms with
the new Day3 convective outlook and think it within the realm of
possibilities that we could have a decent risk east of the mtns
as well. Temps will remain on the warm side of normal.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 312 AM EDT Thursday: The early part of the week remains the
most interesting, with the possibility of an MCS or remnants thereof
might affect our region on Sunday and/or Sunday night. However,
the model guidance, in its fickle nature, looks less favorable for
severe weather. Difficult to read too much into the model change at
this point, and it is worth noting that the overall pattern still
favors MCS remnants topping the upper ridge to our west and making a
run at the srn Appalachians/wrn Carolinas early in the medium range
period, so we won't give up on it just yet. The upper ridge axis
is progged to move overhead on Monday, so that might be something
of a lull in our diurnal storms. This will be followed quickly
by a short wave that might enhance our storm chances Monday night
and/or Tuesday. After that, the signal becomes weak into the middle
part of the week as the upper pattern amplifies with our region
underneath a ridge axis. Temps will be seasonally warm as a result.
&&
.AVIATION /15Z THURSDAY THROUGH MONDAY/...
At KCLT and elsewhere: Cigs are lifting and scattering to VFR across
the region late this morning. Still anticipate good coverage of
convection this afternoon as the upper support arrives from the
west, and all PROB groups are being transitioned to TEMPOs for the
peak convective period. Will retain prevailing SW gusts with mixing
and also TEMPO VRB gusts with thunderstorms. Mainly high debris
clouds will be leftover tonight into Friday under deeper layer
northwest flow. NW gusts will persist at KAVL through the period.
Outlook: Some drying is expected on Friday. Saturday remains fairly
uncertain as a frontal boundary lingers in the area and additional
showers and thunderstorms may move southeast into the region along
the front. A more diurnal pattern to any isolated to sct showers
and thunderstorms is then expected Sunday and Monday. Expect mainly
daybreak restrictions each day, aside from any thunderstorms.
