Area forecast discussion, Mar 25, 10:36 PM EDT, 14 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
1036 PM EDT Thu Mar 25 2021

.SYNOPSIS...
A vigorous cold front is expected to move through the area later
tonight and into Friday and could produce isolated strong to severe
convection along with significant rainfall. The active pattern
continues this weekend as another cold front slides through the
area on Sunday bringing another round of showers and thunderstorms.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 1025 PM Thursday: The cold front was pushing through central
TN and AL with more discrete convection continuing to fire ahead of
it. A couple of these cells tried and failed to hold together as
they pressed into far northeast GA largely due to them running
into the more stable environment. The latest SPC HRRR shows that
later discrete cell should hold together into the western
Carolina's and especially northeast GA as a tongue of 500-1000
CAPE noses into the area from the south thanks to increasing
southerly flow ahead of the front. Feel this could be a bit
overdone but with impressive shear and helicity values should be
enough for at least a few super cell thunderstorms capable of
damaging winds, an isolated tornado, and perhaps large hail.
This threat should be mainly west of I-26 and between roughly
midnight and 4 am. Flood concerns will continue especially for
the southwest mountains. Rainfall totals have already exceeded
5-6 inches at some higher elevations with an additional 1-2
inches possible before all is said and done. The Flash Flood
Watch has been updated accordingly.

As of 830 PM Thursday: The latest surface analysis shows what
appears to be a weak insitu-wedging roughly along and north of I-85
this evening that developed from the steady rainfall from earlier
today. This is indicated by weak high pressure nosing southwest from
the NC Piedmont towards northern GA. This will limit surface based
CAPE and instability overall for this area. This combined with
gradually diminishing upper support as the parent low moves
northeast into the Great Lakes and loss of daytime heating should
limit the coverage of severe thunderstorms compared to neighbors to
our west. That being said SPC recently issued a Tornado Watch for
much of northern GA good through 2 am, just to our west, so we will
be watching the developing situation closely. On that note, high
values of shear/helicity will continue along and ahead of the cold
front, so it probably won't take much instability to maintain strong
to severe thunderstorms (a high shear/low cape environment). Steady
rain with embedded heavy rain will likely continue especially near
the southwest mountains overnight. So we will likely see additional
flooding during this time with the current Flash Flood Watch
seemingly well placed for the time being.

Otherwise, we remain under a weak WAA regime and influence of a
subtropical ridge off the SE Coast. This ridge is downstream of an
expansive trough, within which a potent shortwave will move today,
driving development of a low pressure system over the lower MS
Valley. A significant severe outbreak is expected over portions of
the TN, MS, and AL. Fairly brisk southerly flow has already
initiated convection over the high terrain. The depth and strength
of moisture advection will be impressive, leading to PWATs peaking
near +3 SD, and IVT parameter values that are also anomalously
large. Deep layer hodographs will already be long and curving, but
midlevel lapse rates are not the greatest; the limited instability
will keep our severe threat comparatively small during the day, with
convective layers too shallow to realize all the shear. This does
somewhat limit our heavy rain threat as well, though there will be
widespread coverage and potential for multiple rounds thru tonight.
WPC Day 1 ERO includes most of our SW mtns in a Moderate Risk,
partly because of the aforementioned anomalies and high
probabilities for significant rain rates from the HREF. We are
hoisting a Flash Flood Watch from 18z today to 12z Fri. The same
southerly flow will lead to rather gusty winds, and higher
elevations of the mtns will be exposed to near Wind Advisory-level
conditions.

LLJ is expected to precede the cold front into our area in the
early evening, again enhancing precip generation along the srn
end of the Appalachians; a narrow tongue of sfc based instability
will linger until the front itself enters in the late evening. A
convective line, likely with some embedded rotation will support
vague supercell structure. The dynamic lift provided by the
shortwave will mostly miss our area to the NW as the wave tracks
north of the OH River; this coupled with the unfavorable timing,
and diminishing instability, should begin to impact the convection
particularly as it crosses the mountains. Nevertheless, a narrow
line of strong showers with a few embedded tstms could progress
across the area overnight. Prog soundings reveal that the line will
encounter poor low to midlevel lapse rates, and this would limit sfc
based updrafts and thus tornado risk. The SPC slight risk extending
only into the mtns looks well-placed and even extended slightly
further east. Recent short-term consensus PoPs as well as hourly
NBM seem to be keying better on the shadowing effect of the mtns,
and timing/chances have been revised thru tonight in new fcst grids.

The frontal boundary should push out of the region by 18z Friday
as sfc high builds in to the NW and we enter a post-frontal
environment by the very end of the forecast period. Drier weather
will prevail, with highs in the low 80s in most locations outside
the mountains and 70s in the higher elevations. One factor that
can play a role is how fast the cold front exits the region and
allows for the clouds to scour out.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
As of 145 PM EDT Thursday: the short term picks up at 00Z Saturday,
with a shortwave trough rounding the broader ridge sitting over the
east coast.  By this time, forcing from the trough will largely
be tapering off to the north of our CWA, and a brief bout of
dry weather is in store for Friday night.  Renewed southwesterly
flow over the Tennessee Valley will pump Gulf moisture into the
lower troposphere through the day Saturday, working with weak
mid-level forcing to produce scattered afternoon showers across TN,
spreading into the Blue Ridge Mountains and western SC Upstate
by late Saturday afternoon.  The developing surface low skirts
its way northeast along the Appalachians and drags a cold front
across our area early Sunday afternoon.

Ample WAA ahead of this front paired with decent solar insolation
should prime the environment for convection, with the Piedmont
and Upstate seeing SBCAPE values in the 500-1000 J/kg range and a
40-50kt LLJ riding out ahead of the frontal boundary.  Given the
timing of the frontal passage in the early afternoon, this is a
pattern to keep an eye on over the next day or two.  Some precip
may still be falling for at least the eastern part of our CWA by
the end of the short term at 00Z Monday, as the front tapers off
to the east.

Temps are on track to stay several degrees above normal on Saturday
and Sunday, before dropping back to near-normal Sunday night in
the wake of the cold front.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
As of 200 PM EDT Thursday: by Sunday night, good mid-level forcing
associated with the latest trough is exiting the region to the east,
and precip drops off overnight behind the departing cold front.
We then enter a weak upper ridging regime as high pressure builds
in at the surface.  So, Monday should be dominated by clear,
dry weather as the frontal boundary stalls well south of us.

Meanwhile, the GFS and ECMWF depict a closed upper low meandering
out of the Southern Plains and causing coastal cyclogenesis along
the stagnant frontal boundary.  The resulting surface low tracks
from the Gulf Coast out to the NC/SC coastline.  It looks to only
graze our CWA at this point, yielding chance PoPs on Tuesday
afternoon and overnight.  On Thursday, yet another surface low
pushes into the region from the west, bringing another bout of
rainfall to the region to cap out the week.

Temperatures on Monday and Tuesday look to be a couple degrees
below normal, before southerly WAA brings them back to near-normal
later in the week.

&&

.AVIATION /03Z FRIDAY THROUGH TUESDAY/...
At KCLT and elsewhere: Below normal confidence in 00Z TAFs due to
uncertainty in timing and strength of convective line to move
through the area from west to east between roughly 05Z and 15Z.
Steady rain with isolated TSRA is expected ahead of this feature
with IFR and lower cigs/vsbys likely in heavier shra/tsra. Front may
stall south of TAF sites into Friday with little if any impact to
terminals.

Outlook: Another system may bring showers Saturday with
thunderstorms possible by Sunday.
