Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
313 PM EDT Thu May 26 2022

.SYNOPSIS...
An approaching cold front will trigger widespread showers and
thunderstorms through Friday morning, prompting a threat for
isolated severe weather and localized flooding concerns. After the
passage of the cold front by midday Friday, high pressure builds in
for the weekend, and looks to dominate through the first half of
next week.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 300 PM EDT: A low pressure system is currently located to our
west over the Missouri Valley region will continue tracking east
towards the Midwest and Ohio Valley region the rest of today into
Friday. The cold front associated with this low pressure system will
track across the western Carolinas and northeast GA early Friday
morning into early Friday evening. This system will continue to lead
to widespread shower and thunderstorm development the rest of today
into early Friday morning.

Ahead of the low pressure system, SW'ly flow will be in place near
the sfc across the Southeast allowing Gulf moisture to stream into
the region. This will lead to dewpoints in the 60s across the
majority of the CWA through Friday morning. With PWAT values near or
just above 1.75 inches, which is above 90th percentile, ahead of the
FROPA, plentiful moisture will be in place leading to moderate to
heavy downpours at times. With wet soils already in place from prior
rainfall the last few days, this could allow for enough runoff for a
flash flooding threat across mainly the mountains and NC Foothills.
For this reason, a Flood Watch remains in effect through Friday
morning for with the potential for excessive rainfall leading to the
potential for flash flooding in these areas. A few Flood Advisories
and two Flash Flood Warnings are currently in effect for portions of
the SW NC mtns as well as a portions of the SC mtns in Oconee
County. Rainfall amounts of 2-4 inches have already fallen across
portions of extreme NE GA and the SW NC mtns this morning and early
afternoon. Isolated rainfall amounts of 6-7 inches are possible
along the SW upslope flow zones by the end of this event. The rest
of the mountains could see rainfall amounts ranging from 1.5 to 3
inches with isolated areas of 4 inches possible. Areas east of the
mtns will likely see totals ranging from 1 to 2 inches, with
isolated amounts near 3 inches are possible. So, the rainfall threat
will continued to be monitored closely and with heavier precip
anticipated this evening into tonight.

There is also the potential for strong to severe storms this
afternoon and evening as bulk shear values ranging from 30-40 knots
are in place along with SBCAPE values ranging from 500 to 1,000
J/kg. Instability will continue increase as CAD erodes allowing
SBCAPE values to creep northward this afternoon. SPC currently has
most of our area in a marginal to slight risk. The main potential
impacts are damaging winds gusts, isolated tornadoes and large hail.
Currently seeing showers and thunderstorms, a few strong, across the
western CWA this afternoon. Currently the majority of the eastern
CWA, including CLT is mostly dry. Shower and thunderstorm chances
will increase later this afternoon and early evening over the
eastern CWA. Instability should decrease overnight with the loss of
daytime heating, however cannot rule out isolated strong to severe
thunderstorms overnight into daybreak Friday. Showers and
thunderstorms should mostly taper off from west to east overnight
into early Friday morning. However, wrap around moisture behind the
FROPA could lead to isolated to scattered showers continuing across
the NC/TN border on Friday. A few of these may last past the
mountains leading to isolated to scattered showers possible with the
potential for isolated thunderstorms late Friday afternoon.

High temperatures will remain around 3-7 degrees below climo today
and Friday, but will be about 5-8 degrees above climo overnight
tonight thanks to precip and cloud cover.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
As of 210 pm EDT Thursday: Upper low is forecast to open up as it
wobbles across the central Appalachians and vicinity early in the
period. As the associated trough axis crosses the area Fri night and
interacts with lingering low level moisture, a few light showers may
develop across the mtns/northern zones,warranting 20-30 PoPs in
those areas through around midnight. Drier air filtering in behind
the front will bring an end to any precip chances by daybreak
Saturday, with dry conditions persisting through the period.
Otherwise, temperatures will be around normal until Sunday, when
temps will warm to around 5 degrees above normal in response to
rising upper heights/a building ridge to our west.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
As of 220 pm EDT Thursday: Global models are in good agreement in
developing an expansive anticyclone centered over the
central/southern Appalachians Monday morning, which then gradually
retreats toward the Ohio Valley/mid-Miss Valley by mid-week. For our
forecast area, this will mean a return to very warm conditions, with
temps expected to be around 10 degrees above normal by Tue.
Conditions will also be generally suppressed in terms of the
convective potential, but some isolated diurnal showers and storms
could develop Tue afternoon/evening, esp over the high terrain. With
the anticyclone retrograding, and global guidance pushing an upper
cyclone toward the southeast coast, chances for diurnal convection
will steadily increase during the latter half of the period, with
20-30 PoPs advertised Thu afternoon/evening.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
At KCLT and elsewhere: A low pressure system located to the west is
leading to showers and thunderstorms across the western and central
fcst area this afternoon. Currently the eastern fcst area, including
KCLT, remains mostly dry outside of a few isolated showers.
Currently seeing mostly MVFR conditions with IFR conditions
continuing at KHKY as of 18Z. Shower and thunderstorm chances will
increase later this afternoon for the eastern zones. Have TEMPOs to
account for TSRA this afternoon with associated lowered vsby and cig
restrictions. KCLT may see VFR conditions develop later this
afternoon as the cold air wedge erodes. Elsewhere, MVFR to IFR
conditions can be expected this afternoon. Shower and thunderstorm
chances will continue off and on into early Friday morning across
the terminals. MVFR to IFR cigs and vsbys look to return overnight,
with the possibility of IFR conditions developing near daybreak.
Winds will generally be S/SE'ly through this afternoon, becoming
S/SW'ly overnight into Friday ahead of an approaching cold front.
Low end wind gusts are possible this afternoon and tomorrow
afternoon.

Outlook: Behind the cold front, VFR conditions should return this
weekend into early next week as high pressure builds into the region.
