Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
236 AM EDT Sun May 18 2025

.SYNOPSIS...
A front stalls in the vicinity of the area through Tuesday before
pushing across the area on Wednesday. This will keep unsettled
weather and above-normal temperatures around through mid-week.
Cooler temperatures and drier conditions return behind the
front Thursday into the weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
Key Messages:

1) Relatively quiet Sunday with daytime temperatures above normal.

As of 145 AM EDT Sunday: Generally flat synoptic pattern to start.
By tonight, a trough begins to form out west, causing a downstream
ridge to amplify towards the southeast. The airmass begins to modify
through the period, with increasing moisture by the end of it.
Embedded within the flow aloft, guidance does show a weak shortwave
passing by toward the southern tier of the CWA this afternoon. Some
of the CAMs show a brief period of showers across the southern
zones, but confidence is low. Should a shower pop up, it should
quickly dissipate. For this, will keep a few areas with minimal PoPs
in the 15-20% range and unmentionable PoP elsewhere. By sunset,
activity diminishes and makes way for a drier overnight. Expect much
lighter winds across the area today as well. Temps should be a tad
lower, but still warmer than normal.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
As of 130 AM Sunday...

Key Messages:

1) Shower and Thunderstorm Chances Continue

2) Severe Storms are Possible, Especially on Tuesday

3) Warm with Above Normal Temps Sticking Around

Upper ridging remains over the Southeast while upper shortwaves
track over the western Carolinas and northeast Georgia through the
short term. Meanwhile, a front stalls just south of the CWA Monday
into Monday night before lifting north across the forecast area
Tuesday into Tuesday night while reactivating as a warm front. A
diurnal trend is expected on Monday, with convective chances
gradually increasing from west to east Tuesday into Tuesday night
south of the warm front and ahead of an approaching cold front. With
40-50 kts of deep layer shear and 1,000-1,500 J/kg of SBCAPE
developing each afternoon/evening, strong to severe storms may
develop. Confidence is higher on the severe potential for Tuesday
compared to Monday as instability on Monday looks to be limited to
the western zones while instability on Tuesday should be available
area-wide. Large hail and damaging wind gusts are the primary
hazards with any severe storms that develop through the short term.
Highs each afternoon will end up ~3-5 degrees above normal with lows
each night ending up ~8-12 degrees above normal.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
As of 200 AM Saturday...

Key Messages:

1) Unsettled Weather Lingers through Wednesday with Drier Conditions
Returning for Most Locations the Rest of the Period

2) Breezy Winds Develop Wednesday and Linger through Friday

3) Warm with Above Normal Temps Again on Wednesday Before Cooler,
Below Normal Temps Return Thursday into the Weekend

An upper low will push southeast out of the Midwest on Wednesday
before getting absorbed by another upper low sinking southward out
of Canada Wednesday night into Thursday. The upper low will then
meander over the northeastern CONUS through the remainder of the
forecast period. This will act to push a cold front across the
western Carolinas and northeast Georgia on Wednesday, keeping
unsettled weather around. Strong to severe storms will remain
possible on Wednesday, especially with deep layer shear increasing
to 60 kts, but limited instability will keep confidence low for now.
Although the front will push east of the CWA late Wednesday night,
cyclonic flow aloft will keep NW flow rain showers around for the NC
mountains through the end of the long term. Drier conditions are
expected elsewhere behind the front late Wednesday into Saturday.
Breezy winds will develop Wednesday into Friday before finally
diminishing Friday night. Temps Wednesday into Wednesday night will
remain a few degrees above normal head of the front before cooler
and below normal temps return behind the front Thursday into the
weekend.

&&

.AVIATION /07Z SUNDAY THROUGH THURSDAY/...
At KCLT and elsewhere: VFR conditions prevail through the period.
Winds have decreased but remain WSW at all sites except KAVL, which
remains NW. KCLT could have a brief period of WNW winds after
daybreak before quickly returning SW. Gusts have diminished and
winds should remain light through the forecast period. No vsby/cig
restrictions are anticipated, with the exception of KAVL. There`s a
very low chance of brief valley fog by morning, but confidence is
too low to put into the TAFs. Afternoon cu across the area Sunday
afternoon bring cigs to SCT070-080, but remain VFR.

Outlook: Showers and thunderstorms expected each afternoon Monday
through mid week. Early morning fog/low stratus possible in the
mountain valleys and locations where rain fell the previous
afternoon/evening.
