Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
216 PM EDT Mon May 25 2026

.WHAT HAS CHANGED...
No major changes.

&&

.KEY MESSAGES...
1. Cold air damming erodes during peak heating with shower and
thunderstorm chances returning this afternoon into tonight. This
will allow for a low-end, isolated flash flood threat as a well
as a non-zero strong to severe storm threat.
2. Daily chances for showers and thunderstorms continue into
the weekend. Drier conditions may return briefly on Friday but
confidence is low. We will have a better shot at dry weather
early next week as high pressure builds in from the north.

&&

.DISCUSSION...
Key message 1: Cold air damming erodes during peak heating with shower
and thunderstorm chances returning this afternoon into tonight. This
will allow for a low-end, isolated flash flood threat as a well as a
non-zero strong to severe storm threat.

Cold air damming will gradually erode through peak heating hours
allowing up to 1,000-2,000 J/kg of surface based instability to
develop, per the 12Z high-res guidance and the SPC mesoanalysis
page. Although deep layer shear will be fairly weak, ranging from 15-
25 kts, a few isolated strong to severe storms cannot be entirely
ruled out this afternoon and evening, especially along the edge of
the eroding wedge boundary where any localized surge in SRH occurs.

There will arguably be a slightly higher threat for isolated,
localized flash flooding thanks to wet antecedent conditions.
The Day 1 WPC Excessive Rainfall Outlook agrees with this assessment
with a slight risk in place across much of the forecast area.
Rainfall amounts through 12Z Tuesday look to mostly range from an
0.25-1" east of the mountains and ~0.50-1.5" across the mountains.
Locally higher rainfall amounts up to 1.5-2" are possible east of
the mountains but will be dependent on where the heaviest downpours
track/train. Across the mountains, locally higher amounts of 2-3+"
appear to be confined to the northern escarpment per the 12Z
HRRR/NAMNest. The 12Z REFS shows a 20% to 40% chance of rainfall
greater than 2.5" along the northern escarpment. Although these
probabilities are fairly low, there is still a low-end concern for
highly localized flash flooding across this area in particular if
these higher rainfall amounts were to materialize due to
training/slow storm movement. Went with WPC for QPF through tonight
as this matched up better with high-res guidance trends compared to
the NBM. With this threat expected to remain highly localized, opted
not to issue a Flash Flood Watch as this product is reserved for
more widespread heavy rain/flash flood events.

Patchy fog and low stratus should return again overnight with a
moist airmass lingering in place. Highs this afternoon will end up
near to just below normal with lows tonight ending up 7-10 degrees
above normal thanks to cloud cover and rain.

Key message 2: Daily chances for showers and thunderstorms continue
into the weekend. Drier conditions may return briefly on Friday but
confidence is low. We will have a better shot at dry weather early
next week as high pressure builds in from the north.

Daily chances for showers and thunderstorms (mainly during the
afternoon/evening hours) will continue through Wednesday as an upper
ridge centered offshore the southeast coast in the western Atlantic
works with an upper low over the West Coast to pull in moisture from
the Gulf. Convective chances will linger through Thursday as a
backdoor cold front tracks across the forecast area. Brief drying
may develop behind the front on Friday as dry high pressure attempts
to briefly build in from the north but confidence is low with the
high expected to gradually weaken. The front will stall across the
southeast through the weekend keeping shower and thunderstorm
chances around. Global model guidance is now showing the potential
for drier conditions to return as early as Sunday, lingering into
early next week. However, confidence is low with this being towards
the end of the forecast period. Highs should end up near normal to
just below normal Tuesday afternoon, becoming near normal to just
above normal Wednesday afternoon. Highs on Thursday ahead of the
front will end up a few degrees above normal before dropping to a
few degrees below normal Friday behind the front. Cold air damming
looks to develop this weekend into early next week so highs should
end up ~5-10 degrees below normal. Depending on the strength of the
wedge, as well as how widespread rain ends up being, highs may trend
even cooler.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
At KCLT and elsewhere: Cigs are gradually improving this afternoon
with mostly MVFR to VFR noted across the terminals as of 18Z. Cigs
should lift to VFR levels briefly, outside of SHRA/TSRA chances this
afternoon/early evening, before gradually lowering to IFR/LIFR
levels late this evening into daybreak Tuesday. Maintained PROB30s
for TSRA this afternoon/evening at KCLT and the SC Upstate terminals
as confidence is low on whether TSRA will track directly over these
terminals. Confidence is higher for TSRA this afternoon and evening
over KAVL and KHKY so went with TEMPOs for these terminals. Thunder
chances should gradually wane with the loss of daytime heating so
have prevailing SHRA mentioned at KAVL and KHKY during the overnight
hours as these terminals are mostly likely to see activity continue.
Went with either VCSH or dry conditions for KCLT and the SC
terminals as confidence on precip hanging around is very low. Vsbys
will lower overnight into early Tuesday morning, ranging mostly from
MVFR to IFR. However, heavier SHRA may lead to even lower vsbys.
Drier conditions can be expected Tuesday morning/early afternoon
outside of KHKY, with vsbys improving by mid-morning. Wind direction
will be mainly S/SW through the 18Z TAF period, although KAVL may
toggle more SE overnight. Winds should go light and VRB to calm
tonight across most terminals.

Outlook: The pattern remains unsettled through the workweek with at
least scattered diurnal convection expected each day (possibly
persisting into the overnight hours) and lowered visibility and
ceilings forecast each night.
