Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
223 AM EDT Sun Mar 15 2026

.WHAT HAS CHANGED...
Confidence continues to increase regarding severe weather late
tonight into Monday afternoon.

Snowfall accumulations on Monday increased slightly but still appear
to remain below Winter Weather Advisory criteria outside of the
highest elevations. Additionally, northwest flow snow now looks to
linger through at least daybreak Tuesday.

&&

.KEY MESSAGES...
1. Scattered showers and thunderstorms return to the area this
afternoon.
2. A strong cold front will bring the potential for severe
weather late Sunday into Monday afternoon with the main hazards
being damaging winds and isolated tornadoes. Make sure you have
multiple ways to receive warnings and think about where you would
seek safe shelter if a warning was issued for your location.
3. A brief period of northwest flow snow will develop in the
North Carolina mountains Monday into Monday night, with light
accumulations possible.
4. Gusty winds will develop ahead of and behind the cold front
Sunday night through Tuesday before finally tapering off Tuesday
evening. A Wind Advisory may be needed for portions of the North
Carolina mountains Monday into Monday night.
5. A much colder and drier air mass returns behind the front
Monday night into Wednesday night with most areas seeing lows each
night falling near or below freezing. Warmer temperatures return
Thursday into the weekend with mostly dry conditions continuing.

&&

.DISCUSSION...
Key message 1: Scattered showers and thunderstorms return to the
area this afternoon.

Low level moisture and isentropic lift increase through the day in
increasing low level southeasterly flow. Increasing cloudiness
expected through the day. The latest guidance shows some weak CAD-
like development during the afternoon, limiting any sbCAPE potential.
Even muCAPE is limited across much of the area. The CAMs show
scattered showers and isolated storms given the forcing. That said,
they have backed off on the severe potential for the afternoon
despite the increasing shear and helicity. Still, should any sbCAPE
develop, any resulting storms could take advantage of the better
environment, possibly becoming severe. Overall, the better severe
storm chances begin tonight.

Key message 2: A strong cold front will bring the potential for
severe weather late Sunday into Monday afternoon with the main
hazards being damaging winds and isolated tornadoes. Make sure you
have multiple ways to receive warnings and think about where you
would seek safe shelter if a warning was issued for your location.

A strong cold front will approach out of the west Sunday evening
before tracking over the forecast area Sunday night into Monday
afternoon, bringing the potential for severe weather. The severe
threat will be highest from the early morning hours Monday through
mid-afternoon Monday. Confidence continues to increase regarding the
damaging wind and tornado potential as instability will gradually
increase across the area Sunday night into Monday afternoon and as
plentiful moisture and forcing will be available ahead of and along
the frontal boundary. Some storms may develop ahead of the main
line, but the severe threat with this activity should remain low.

00Z CAMs depict the QLCS (line of storms) pushing across the western
half of the forecast area from roughly 5 AM to 10 AM Monday before
pushing across the eastern zones from roughly 11 AM to 3 PM Monday.
Although the western two-thirds of the GSP CWA will see the front
track overhear prior to peak heating, there will be enough forcing
and instability in place to allow for severe storm development.
MUCAPE across these zones will range from a few hundred to several
hundred J/kg, but will generally remain below 1,000 J/kg per the 00Z
HRRR and NAMNest. Some SBCAPE may develop across these zones after
sunrise, but will also generally remain less than 1,000 J/kg. The
eastern third of the GSP CWA (areas south of I-85 and near the I-77
corridor..which includes the Charlotte Metro) will have the best
potential to see the line swing through during peak heating. Thus,
these areas will be of most concern regarding severe weather as
SBCAPE from 1,000 to 1,500 J/kg should available per the 00Z NAMNest
and HRRR. Thus, the SPC Day 2 Severe Weather Outlook showing an
enhanced risk over the eastern third of the GSP CWA with a marginal
to slight risk elsewhere, appears warranted. The entire GSP CWA will
have the potential to see damaging winds and isolated tornadoes with
this line of storms, despite the lack of impressive instability,
thanks to 50 to 60 kts of deep layer shear, a 40 to 50 kt LLJ
tracking overhead, and 200 to 300 J/kg of 0-1km of SRH developing
ahead of the front. Additionally, the 00Z HRRR and NAMNest depict
updraft helicity swaths ahead of and along the front, showing the
potential for rotating updrafts which further increases confidence
regarding the potential for embedded tornadoes and damaging wind
gusts near the leading edge of the line.

Now is the time to make your severe weather preparations. Make sure
you have multiple ways to receive warnings such as NOAA Weather
Radio, Wireless Emergency Alerts (WEA), social media, or local TV
and radio. If you live in a mobile or manufactured home make plans
ahead of time to stay with friends or family who live in a sturdy
building as mobile/manufactured homes are not safe shelters from
tornadoes.

Drier conditions will gradually return from west to east behind this
system from the mid-afternoon hours to the early evening hours
Monday.

Key message 3: A brief period of northwest flow snow will develop in
the North Carolina mountains Monday into Monday night, with light
accumulations possible.

Temperatures will drop steadily behind the cold front throughout
Monday, falling below freezing across the North Carolina mountains
Monday afternoon into Monday evening. This will allow northwest flow
snow showers to develop, especially along the NC/TN border. Although
snowfall accumulations have increased slightly this forecast cycle,
they are still expected to remain light and below advisory criteria
for most locations. However, the Smokies, as well as areas above
5,000 ft in the northern North Carolina mountains, should see totals
near or just above advisory criteria (around or greater than 2").
With advisory level accums remaining confined to the higher
elevations, and the NBM only showing a 20% to 30% chance of greater
than 2" of snowfall in 24 hours along the NC/TN border, a Winter
Weather Advisory remains unlikely. Lower elevations across the North
Carolina mountains could see anywhere from a dusting to up to an
inch of snowfall.

Key message 4: Gusty winds will develop ahead of and behind the cold
front Sunday night through Tuesday before finally tapering off
Tuesday evening. A Wind Advisory may be needed for portions of the
North Carolina mountains Monday into Monday night.

Winds will steadily increase ahead of the cold front Sunday evening
into Monday afternoon, with speeds continuing to increase across the
North Carolina mountains behind the front Monday afternoon into
Monday evening as winds shift NW. A Wind Advisory may be needed for
portions of the North Carolina mountains Monday into Monday night,
mainly for the higher elevations. Gusts east of the mountains still
look to remain below 45 mph so an advisory looks less likely for
these zones. Gusty winds will linger through Tuesday afternoon
before gradually diminishing Tuesday evening into Tuesday night.
However, wind speeds will be much lower on Tuesday compared to
Monday.

Key message 5: A much colder and drier air mass returns behind the
front Monday night into Wednesday night with most areas seeing lows
each night falling near or below freezing. Warmer temperatures
return Thursday into the weekend with mostly dry conditions
continuing.

Surface high pressure builds in from the west behind the departing
front Monday night into Wednesday, allowing drier and much colder
conditions to return. Temperatures will run well below normal
through mid-week. Temperatures Monday night and Tuesday night will
fall below freezing. Although slightly warmer low temperatures are
expected to return Wednesday night as the center of the surface high
pushes offshore, most of the area will see lows fall near freezing
to below freezing as the NBM has trended slightly colder. Sensitive
plants that have already bloomed from the recent abnormally warm
weather will be particularly vulnerable to these cold temperatures
each night.

Warmer temperatures return Thursday into the weekend with mostly dry
conditions continuing as the southwestern periphery of the surface
ridge remains extended over the Carolinas. Highs on Thursday will be
noticeably warmer, but will still end up a few degrees below
normal (outside the mountain valleys) before much warmer and
above normal highs return Friday into Saturday.

&&

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
At KCLT and elsewhere: Tricky forecast this period with low level
moisture and isentropic lift increasing this morning. Some guidance
has backed off on the development of restrictions, keeping them more
spotty or low VFR, while others show MVFR cigs developing. Given the
pattern, have MVFR cigs developing by mid morning, closer to noon
for KCLT and KHKY. Cigs fall through MVFR with IFR by evening.
Scattered showers and possibly a thunderstorm move north across the
area during the afternoon, have PROB30s in place for these, but kept
at SHRA for now. IFR cigs continue overnight, although some
improvement to MVFR is possible. Shower and thunderstorm chances
increase overnight as a cold front moves into the area from the
west. SE wind early this morning turns more ENE after daybreak.
Winds turn back to the SE for the afternoon into the evening.
Occasional gusts are possible.

Outlook: A strong cold front will swing across the region early
Monday morning before pushing east by the afternoon. This will bring
a fast moving line of thunderstorms, some of which are expected to
be severe. Associated restrictions will be possible along with low
stratus ahead of the line. VFR conditions return thereafter, albeit
with continued wind gusts. Gusts end by Wednesday with VFR through
Thursday.
