Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
300 PM EDT Mon May 12 2025

.SYNOPSIS...
Low pressure will move slowly northeast across the Tennessee River
Valley tonight and Tuesday then over the Ohio River Valley in mid
week.  Numerous showers and thunderstorms will continue across our
region through Tuesday with the heavy rain resulting in some
flooding through tonight, mainly over the eastern side of the
mountains. Drier high pressure moves over our area Thursday then a
cold front stalls to our north for the weekend with scattered to
numerous showers and thunderstorms and above normal temperatures
across our region.

&&

.NEAR TERM /THROUGH TUESDAY/...
As of 200 PM: A virtually stacked low pressure system is seen on
water vapor imagery and sfc analysis, centered over the Mississippi
Delta region. A broad region of SE'ly flow is occurring over the
Carolinas/Georgia on the warm side of this system; isentropic
lift generally will persist through tonight. Weak in-situ cold air
damming persists over the region, having developed Sunday. Difficult
to pick out exactly where the wedge boundary is, but it appears
to be well south of the CWA. The edge of more stratiform clouds
now west of the Savannah River appears aligned with the leading
edge of a midlevel dry slot which will shift slowly east over the
area over the next 12 hours. Differential heating along that cloud
edge and slightly cooler air aloft have led to development of a
band of convection gradually shifting into the area. The wedge may
slowly erode along this boundary via mixing. Some breaks are also
seen in the SC Midlands as a result of diurnal warming. LCLs are
already low, but surface-based convection will become increasingly
possible with any low-level clearing. A few hundred J/kg of SBCAPE
is progged over the eastern areas with more than 1000 possible near
the Savannah River. Although winds aloft are not especially strong,
with sfc winds being backed at SE to E, low-level shear and helicity
are fairly high: 0-1km shear of 25-30 kt and 0-3km SRH exceeding
200 m2/s2. Bands of showers/storms with weak circulations have
been observed on radar at numerous times today and with increasing
instability, the tornado threat will increase.

Elevated PWATs and the potential for multiple rounds of
showers/storms suggest the threat of excessive rainfall is
nonzero. CAM output has gradually trended toward lower total QPF
and less supportive of hourly rates near flash-flood guidance. No
changes have been made to the extent of the previously issued Flood
Watch, with the focusing mechanism of the Blue Ridge Escarpment
in the persistent southerly flow regime being the most concerning
element; it looks well placed in that regard.

Slow northward movement of the low will veer low-level winds
tonight, weakening moisture flux; dry slot will also shift over
the area. Shear parameters will diminish during the evening;
surface-based storms also will become less likely. Hence the tornado
threat too is expected to diminish. PWATs decline from west to
east between approx. 03z-09z tonight as the dry slot expands
over the area. The heavy rain threat likely will taper off in
that timeframe as well. There won't be much of a wedge erosion
mechanism, so whatever is left could remain into morning until
diurnal insolation can work to thaty effect. The closed portion
of the 500mb low will drift north over TN/KY by that time, so we
will see 700-500mb lapse rates increase to near 7C/km during peak
heating Tuesday. Profiles will not be saturated thru a deep layer
like today/tonight, but should be supportive of deep updrafts. For
now have kept PoPs mostly in the scattered to low likely range
(the latter over the mountains). Can't completely rule out severe
weather, with 0-6km shear of 30+ kt supportive of multicells
producing a wind or marginally severe hail threat.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
As of 1225 PM Monday: The upper low will be departing from the area
at the beginning of the short range period with ridging asserting
itself across the region by Thursday. This will lead to a shift in
the low level flow to more westerly/southwesterly and more diurnal
showers/storms each day with overall lighter rainfall amounts. High
temperatures are expected to be around normal on Wednesday climbing
to several degrees above normal on Thursday.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
As of 1235 PM Monday: The upper ridging pattern will shift quickly
to the east by Friday and then off the coast by the weekend. An
upper low over the Great Lakes states will create an active storm
pattern across the Ohio and Tennessee Valleys for Friday into the
weekend. A northwest flow pattern that will set up between the low
and ridging to our southwest, causing some of these storms to make a
run at our area during the extended period. Thus, will maintain the
chance of showers/storms through the extended period.

High temperatures through the extended period look to average around
5 degrees above normal.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
At KCLT and elsewhere: Where precip does not occur this afternoon,
mostly MVFR to low VFR stratocu will prevail thru early evening;
wholesale deterioration in cigs is expected tonight. Multiple rounds
of convective precip (SHRA) however are likely at all terminals
through tonight with a chance of TSRA. Any flavor of precip will be
capable of bringing IFR cig, with isolated +SHRA or TSRA potentially
resulting in IFR to LIFR vsby. Utilized TEMPO for relatively higher
confidence fcst of restrictions per radar/obs trends early in the
period, with PROB30 generally handling less certain development
in the late aftn/evening. TSRA most likely between issuance and
sunset, although can't be ruled out in the first few hrs of the
night. Precip becoming less likely late tonight from S to N. IFR
to LIFR cigs thru daybreak with low vsby particularly likely where
precip does end. Scattering cigs in some areas by late morning
Tue with MVFR to low VFR bases. Diurnally driven SHRA or even TSRA
could develop after 18z Tue which prompted another PROB30 at KCLT.

Outlook: SHRA/TSRA gradually taper off Tue night. Drier conditions
return by mid-week, but sufficient moisture will likely remain to
support at least scattered diurnal showers and thunderstorms.
