What was reported inside it

Time	Report	Where	Remark
Jul 4, 4:17 PM EDT	HAIL 0.5	3 Sw Cashiers, NC	MARBLE SIZED HAIL ON TWIN LAKES DRIVE. MINOR WIND GUST.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Peachtre/Fal Fld, GA (KFFC), launched 12:00Z, 8.3 hours before the alert went out and 226 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 4, 2:52 PM EDT, 1 hour 23 minutes earlier.

Area forecast discussion, Jul 4, 2:52 PM EDT, 1 hour 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
252 PM EDT WED JUL 4 2012

.SYNOPSIS...
A WEAK UPPER LEVEL TROUGH OVER THE AREA WILL CONTINUE MOVING EAST
THROUGH FRIDAY. STRONG UPPER LEVEL RIDGING WILL BUILD IN FOR THE
WEEKEND AND ALLOW TEMPERATURES TO REMAIN ABOVE NORMAL WITH VARYING
COVERAGE OF AFTERNOON AND EVENING THUNDERSTORMS.

&&

.NEAR TERM /THROUGH THURSDAY/...
CONVECTION HAS FIRED OVER THE HIGH TERRAIN AS EXPECTED...AND ALONG A
LEE TROUGH/CONVERGENT AXIS ACROSS THE NC PIEDMONT. COVERAGE SHOULD
CONTINUE TO GRADUALLY EXPAND...AS MID-LEVEL SHORT WAVE TROUGH
CONTINUES TO DROP TOWARD THE REGION...SO WE CONTINUE TO FEEL GOOD
ABOUT THE 40-50 POPS COVERING MUCH OF THE AREA. INSTABILITY IS QUITE
A BIT LESS THAN YESTERDAY...OWING TO WEAKER MID-LEVEL LAPSE RATES.
THEREFORE...WE/RE NOT EXPECTING THE COVERAGE OF PULSE SEVERE STORMS
THAT WE SAW YESTERDAY. HOWEVER...LOW LEVEL SHEAR IS STRONGER THAN
YESTERDAY...SO THERE IS A CHANCE THAT CONVECTION WILL CLUSTER ALONG
COLD POOLS...AND THIS WOULD POSE A HIGHER DOWNBURST THREAT.

CONSIDERING THE EARLY START TO CONVECTION...AND THAT THE SHORT WAVE
WILL PASS SOUTH OF THE AREA THIS EVENING...COVERAGE SHOULD DIMINISH
FAIRLY QUICKLY AFTER SUNSET. THE FLOW IS EXPECTED TO VEER SOMEWHAT
TONIGHT...AS HEIGHTS BEGIN TO RISE IN THE WAKE OF THE SHORT WAVE.
THIS RETURN TO MORE NORTHERLY FLOW WILL POSE THE POTENTIAL FOR
CONVECTION ORIGINATING OVER THE GREAT LAKES REGION TO DROP TOWARD
THE AREA EARLY THURSDAY MORNING. ALTHOUGH SOME OF THE HIGH RES
MODELS HINT AT THIS OCCURRENCE...I DONT PUT A GREAT DEAL OF FAITH IN
IT...AS SHEAR IS AWFULLY WEAK EVEN THAT FAR UPSTREAM.
NEVERTHELESS... WILL INTRODUCE CHANCE POPS ACROSS THE NORTHWEST
ZONES AT THE START OF THE SECOND PERIOD.

AS THE RIDGE BEGINS TO NOSE BACK INTO THE AREA THURSDAY...FLOW ALOFT
BECOMES VERY WEAK AND TEMPS WARM A LITTLE ALOFT. MODEL CAPE VALUES
AND FORECAST SOUNDINGS ARE STILL QUITE UNSTABLE...BUT INTERESTINGLY
ENOUGH...NEITHER THE NAM NOR THE GFS GENERATE ANY CONVECTIVE PRECIP
OUTSIDE THE MTNS. WE WILL NEVERTHELESS FEATURE CHANCE POPS IN ALL
AREAS TOMORROW...BUT COVERAGE SHOULD BE LESS THAN THIS AFTERNOON.
TEMPS THROUGH THE PERIOD REMAIN AT LEAST A CATEGORY ABOVE CLIMO.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
AS OF 115 PM WEDNESDAY...UPPER HEIGHTS WILL RISE ACROSS THE EAST
FROM THE SPRAWLING RIDGE CENTERED OVER THE MIDWEST THU NIGHT THROUGH
FRI. CANNOT RULE OUT AN MCS MAKING A RUN SE FROM THE OH VALLEY FRI
MORNING...BUT THE BETTER CONVECTIVE CHANCES APPEAR TO BE DURING THE
DIURNALLY FAVORED FRI AFTN/EVENING PERIOD. SCT CONVECTIVE
DEVELOPMENT SHOULD OCCUR OVER THE MTNS EARLY FRI AFTERNOON AND THEN
OVER THE PIEDMONT LATER ON IN NRLY STEERING FLOW AND WITH LOW LEVEL
LEE TROUGH CONVERGENCE. THE NAM FEATURES SOME 4000 TO 5000 J/KG SFC
BASED CAPES FRI AFTN...BUT THIS APPEARS A BIT OVERDONE GIVEN THE NAM
SFC DEWPOINTS IN THE UPPER 70S. ALTHOUGH MID LEVEL LAPSE RATES ARE A
LITTLE LACKLUSTER GIVEN THE WARM AIRMASS...SLIGHT MID LEVEL DRYING
WILL LIKELY ENHANCE THE MICROBURST THREAT...ESPECIALLY OVER THE
PIEDMONT FRI AFTN/EVENING. TEMPS REMAIN WELL ABOVE NORMAL BUT BELOW
HEAT ADVISORY LEVELS.

THE GRADUALLY FLATTENING RIDGE WILL STRETCH ACROSS THE FORECAST AREA
THROUGH SATURDAY. WITH DRYING IN THE PROFILES FROM THE NE...THE BEST
CONVECTIVE CHANCES MAY GET SHUNTED SW TOWARD THE UPPER SAVANNAH
RIVER AREA...BUT WILL LIKELY PERSIST OVER THE HIGHER TERRAIN. SAT
AFTN MAX TEMPS SHOULD BE COMPARABLE TO FRI AFTN VALUES.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
AS OF 100 PM WEDNESDAY...NO BIG CHANGES ARE NEEDED FOR THE EXT
RANGE. THE MODELS HAVE BEEN PRETTY CONSISTENT WITH THE OVERALL
PATTERN EVOLUTION THE PAST SEVERAL RUNS. THE LATEST GEFS ENS ALSO
CONTINUES TO SHOW LITTLE SPREAD AROUND THE H5 Z MEAN. STILL
ANTICIPATE THE UPPER RIDGE TO WEAKEN AS AN EAST COAST TROF FORMS IN
RESPONSE TO -NAO BLOCKING DOWNSTREAM. THIS WILL ALLOW A SFC HIGH
ACROSS THE OH VALLEY TO BE REINFORCED AND PUSH A COLD FRONT INTO THE
REGION BY LATE MONDAY OR TUESDAY MORNING. THERE ARE TIMING
DIFFERENCES BTW THE ECMWF AND GFS WITH THE FRONTAL MOVEMENT...BUT
ONLY ABOUT 6-8 HRS BY MON NIGHT. SO...DECENT CONFIDENCE IS HAD IN
INCREASING POPS AHEAD OF THE FRONT SUN NIGHT THROUGH TUE WHEN THE
FRONT BECOMES STATIONARY ACROSS THE SRN ZONES OR NRN MIDLANDS. STILL
KEPT POPS IN THE CHANCE RANGE...BUT AT THE HIGH END MON AFTERNOON
AND EVENING MAINLY ACROSS THE HIGHER ELEVATIONS. THERE SHOULD BE
SOME ENHANCEMENT TO THE TSTM ACTIVITY WITH THE LLVL LIFT AND DEEPER
SHEAR DEVELOPING AHEAD OF THE TROF AXIS...THUS CONTINUED BOUTS OF
STRONG TO SEVERE STORMS EACH AFTERNOON IS EXPECTED. MAX TEMPS WILL
BEGIN THE PERIOD A FEW DEGREES ABOVE NORMAL SUN...THEN LOWER A
COUPLE DEGREES FOR MON AND TUE AS THE BOUNDARY HELPS INDUCES A GOOD
AMOUNT OF CLOUD COVERAGE OVER THE FA.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
AT KCLT AND ELSEWHERE...CONVECTION IS FIRING OVER THE HIGHER TERRAIN
ONCE AGAIN THIS AFTERNOON IN A MODERATELY UNSTABLE AIR MASS. AS
CONDITIONS CONTINUE TO DESTABILIZE...COVERAGE OF CONVECTION SHOULD
INCREASE. WITH AN UPPER LEVEL DISTURBANCE CROSSING THE REGION THIS
AFTERNOON AND STRONGER FLOW ALOFT...OVERALL COVERAGE SHOULD BE A
LITTLE HIGHER THAN YESTERDAY...AND A TEMPO FOR TS HAS BEEN INCLUDED
AT KCLT BY 20Z...WITH VCTS AT ALL OTHER TERMINALS. A WEAK LEE TROUGH
CURRENTLY BISECTS THE FORECAST AREA...AND IT APPEARS THAT THIS WILL
KEEP WINDS N OR NW AT KCLT FOR THE TIME BEING...BUT A TURN TO THE W
AND SW IS POSSIBLE AS THE POSITION OF THE LEE TROUGH FLUCTUATES.
OTHERWISE...VFR CONDITIONS ARE ANTICIPATED THROUGH THE PERIOD.

OUTLOOK...ISOLATED TO SCATTERED AFTN/EVE SHRA/TSRA EXPECTED EACH DAY
THROUGH THE REST OF THE WEEK...WITH AREAS OF MORNING FOG/STRATUS
POSSIBLE...ESP IN THE MTN VALLEYS.
