...FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 5 AM EDT EARLY THIS
MORNING FOR NORTH CENTRAL CLEVELAND, NORTHWESTERN GASTON AND WESTERN
LINCOLN COUNTIES...

At 404 AM EDT, Doppler radar and automated rain gauges indicated
heavy rain was moving back into the warning area from the southwest.
thunderstorms producing heavy rain across the warned area. Between 2
and 4 inches of rain have fallen across the area since 1:00 AM. The
next round of rainfall is expected to produce up to an additional
inch through 6:00 AM. This will result in continuation of any ongoing
areas of flooding.

HAZARD...Flash flooding caused by thunderstorms.

SOURCE...Radar and automated gauges.

IMPACT...Flash flooding of small creeks and streams, urban areas,
         highways, streets and underpasses as well as other poor
         drainage and low-lying areas. Impacted creeks include Indian
         Creek, Little Indian Creek, and Leonard Fork.

Some locations that will experience flash flooding include...
  Lincolnton, Cherryville, Belwood, Boger City, Vale and Crouse.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Please report observed flooding to local emergency services or law
enforcement and request they pass this information to the National
Weather Service when you can do so safely.

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Be especially cautious at night when it is harder to recognize the
dangers of flooding.

Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
826 PM EDT Sun Jul 12 2026

.WHAT HAS CHANGED...
Updated the aviation discussion for the 00z TAFs.

&&

.KEY MESSAGES...
1. Very active convective weather is expected to continue through
at least Monday. Isolated severe storms and localized flash flooding
will be possible today through Monday. Otherwise, a cooling trend
is expected, with well-below normal high temperatures forecast
Monday and Tuesday.
2. A return to seasonably hot and drier conditions is expected
during the latter half of next week.

&&

.DISCUSSION...
Key message 1: Very active convective weather is expected to continue
through at least Monday. Isolated severe storms and localized
flash flooding will be possible today through Monday. Otherwise, a
cooling trend is expected, with well-below normal high temperatures
forecast Monday and Tuesday.

A 500 mb vort max can be seen drifting over the OH/TN valleys toward
the Southern Appalachians on WV imagery. This feature will help
support a couple more rounds of convection across the area. The
first will be with daytime heating, as the moist air mass in place
has destabilized to around 2000-2500 J/kg. With the approaching
wave, bulk shear will increase slightly, approaching 25-30 kt,
which is decent for mid-July. The CAMs show hints of multicell
clusters and even some rotating updrafts, especially across the
Upstate and NE GA Piedmont where mid clouds have cleared out the
most. The Day 1 Convective Outlook has been adjusted with slight
risk trimmed to the southern third or so of the CWFA. Damaging wind
gusts will be the primary threat, but with a little more shear,
large hail up to quarter-sized will be possible.

Tonight, a weak backdoor cold front will slide south thru the area,
helping trigger additional convection thru this evening. Then,
low-level flow turns out of the E/SE on the north side of the front,
with upslope forcing enough to trigger another round of showers
late overnight thru early Monday morning. The 12z CAMs are still
not in great agreement on coverage and placement, but seem to favor
the northern NC escarpment and adjacent foothills. The signal is
still too subtle to warrant a Flash Flood Watch. Nevertheless,
a slight risk of excessive rainfall continues tonight, with PWATs
around 2" and warm cloud depths over 10 kft.

There should be a relative lull in shower coverage mid to late
Monday morning, as an area of low clouds spreads over the forecast
area and persists until around midday. A 1021-1023 mb sfc high over
the Mid-Atlantic may be strong enough combined with low clouds
and spotty precip to produce an in-situ CAD. Temps will be about
10-15 deg below normal across most of the area as a result. The
clouds and cool temps will limit instability. But guidance shows
pretty solid coverage of diurnal PoPs again Monday aftn-eve. A
decent amount of elevated CAPE should support at least scattered
tstms embedded within numerous to widespread showers. PWATs will
remain around 2"+, so excessive rain will still be a concern,
although muted slightly by less available instability.

Relatively cool/mostly stable and showery conditions continue into
Tuesday...although guidance signals advection of drier air into
the heart of the forecast area from the N and NE. Still can't rule
out some degree of a heavy rainfall threat around the southern and
western periphery of the CWA Tuesday, but much of the area may
well be free of convection Tue afternoon. Forecast maxes remain
around 10 degrees below normal Tue.

Key message 2: A return to seasonably hot and drier conditions is
expected during the latter half of next week.

An upper ridge will persist across the central and northern Great
Plains, while a weak upper low will retrograde across the Southeast
toward TX. Upper ridging will gradually nose east/southeast into
our region thru the end of the week, resulting in seasonably hot
conditions to return to the CWFA Thursday thru next weekend. The 12z
guidance has trended a little drier for Thursday and Friday, then
some increase in diurnal convection over the weekend. Generally
isolated to widely scattered convection in the mountains, with
very isolated activity in the Piedmont until slightly higher PoPs
Saturday and Sunday.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
At KCLT and elsewhere: We currently have some widely sct showers
and a few thunderstorms across our fcst area early this evening.
This activity will likely linger thru the evening, with most sites
carrying VCSH with a PROB30 for TSRA for the next few hrs. A back-
door front will slip in from the NE and toggle winds out of the NE
to ENE outside of the mtns, but speeds should remain light. Moist
ELY flow will support additional showers and the expansion of MVFR
to IFR cigs across the area overnight thru Monday morning. IFR cigs
may persist into the early afternoon before lifting to MVFR. With
the wedge-like airmass in place tomorrow, confidence remains low
to moderate with regards to TSRA coverage during the aftn/evening.
Nonetheless, better coverage is expected over the NC Piedmont so
KCLT and KHKY carry TEMPOs for TSRA from roughly 20 to 24z, while
the other TAF sites are limited to PROB30s for TSRA starting a bit
earlier.

Outlook: Drier conditions should develop Tuesday into Wednesday.
Low stratus and/or fog will be possible each morning in the mtn
valleys and in locations that receive appreciable rainfall from
the previous day.
