The radar

The Greer radar (KGSP), 131 km from the middle of the area, began a volume at 22:49 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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

Greensboro/Hi Pt, NC (KGSO), launched 12:00Z, 10.8 hours before the alert went out and 120 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 May 14, 6:15 PM EDT, 33 minutes earlier.

Area forecast discussion, May 14, 6:15 PM EDT, 33 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
615 PM EDT SAT MAY 14 2011

.SYNOPSIS...
LOW PRESSURE AND AN ASSOCIATED COLD FRONT WILL MOVE EAST TOWARD THE
CAROLINA COAST TONIGHT. THIS LOW WILL LINGER ALONG THE CAROLINA
COAST THROUGH THE FIRST PART OF NEXT WEEK.

&&

.NEAR TERM /THROUGH SUNDAY/...
AT 610 PM...A QLCS WAS LOCATED ALONG A COLD FRONT OVER CLEVELAND AND
CHEROKEE COUNTIES...TRACKING NORTHEAST AROUND 25 KTS. VELOCITY DATA
FROM THE KGSP 88D AND TCLT INDICATE GUSTY SFC WINDS BETWEEN 35 TO
40 MPH. THIS LINE IS APPROACHING SLIGHTLY MORE UNSTABLE AIR OVER THE
I-77 CORRIDOR. GIVEN THE SUPPORT OF THE COLD FRONT / COOL POOL AND
UNSTABLE ENVIRONMENTAL CONDITIONS...THE LINE OF STORMS SHOULD
CONTINUE ACROSS THE REMAINDER OF THE CWA. I WILL INCREASE POPS TO
100 PERCENT AHEAD OF THE LINE. BEHIND THE FRONT...CAPE ANALYSIS
INDICATES VERY LOW INSTABILITY WITH SHALLOW CLOUD FEATURES ON THE
SAT. I WILL REDUCE POPS TO SCHC OR LESS UNTIL SUNSET...THEN POPS
LOWER FURTHER. CAA SHOULD SUPPORT THE CURRENT NEAR NORMAL MIN
FORECAST.

PREVIOUS DISCUSSION...
THE INCREASED MIXING AND CONTINUED INFLUX OF LLVL DRY AIR IS
EXPECTED THRU SUNDAY WITHIN THE DEEP CYCLONIC FLOW ALOFT. THE
COMBINATION OF ENCROACHING CHANNELED VORT ENERGY...COOLER TEMPS
ALOFT AND LINGERING SFC-70H MOISTURE WARRANTS SHOWER CHANCES FOR THE
NC MTNS...AND THEN STRETCHING INTO THE PIEDMONT DURING THE
AFTERNOON. ELSEWHERE...A MIX OF SUN AND CLOUDS ALONG WITH BREEZY
CONDITIONS ARE ON TAP WITH MAX TEMPERATURES WITHIN A CATEGORY OF
MID-MAY NORMALS.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
AS OF 215 PM SAT...AN UPPER LOW WILL AFFECT THE REGION THROUGH THE
MIDDLE PART OF THE FORECAST. SUNDAY NIGHT THE AREA WILL BE BETWEEN
TWO SPOKES OF SHORT WAVE ENERGY. ONE WILL MOVE UP TOWARD VA...WHILE
THE OTHER WILL BE DIVING DOWN THE BACK SIDE OF THE LOW. THE
RELATIVELY WEAK FORCING OVER OUR AREA SHOULD YIELD MAINLY CLOUDY
SKIES WITH SOME LIGHT RAIN OR SHRA MAINLY UP OVER THE MTNS AND NRN
FOOTHILLS.

AS THE STRONG WAVE MOVES THROUGH THE BASE OF THE TROUGH ON
MONDAY...THE FA WILL BE UNDER INCREASINGLY BETTER FORCING. LLVL WARM
ADVECTION AND UPGLIDE ARE LACKING...BUT THERE SHOULD STILL BE GOOD
COVERAGE OF RAIN AND SHRA OVER THE NRN ZONES DURING THE DAY AND
LIKELY POPS ARE IN THE FORECAST FOR THESE AREAS.

MON NGHT AND TUE MODEL DIFFERENCES START TO DEVELOP.
INTERESTINGLY...THE 09 UTC SREF IS FARTHER SOUTH WITH THE H5 UPPER
LOW THAN EITHER OF THE 12 UTC RUNS OF THE GFS OR NAM. OF THE
TWO...THE NAM IS THE CLOSET. THE 12 UTC CANADIAN IS SIMILAR AND HAS
BEEN CONSISTENT THE PAST COUPLE RUNS. THIS SHOULD KEEP LIGHT RAIN
AND SHRA OVER THE NRN PART OF THE FA MONDAY NIGHT...THOUGH PCPN
DOESN/T LOOK HEAVY OWING TO A CONTINUED LACK OFF LLVL MOISTURE
TRANSPORT. BY TUE...THE DEEPER NAM AND SREF SPREAD A LITTLE HEAVIER
PCPN INTO THE NC ZONES IN THE AFTN. WHILE THE RAINFALL WILL BE MUCH
HEAVIER UP INTO THE CENTRAL APPALACHIANS...RAIN STILL LOOKS LIKE A
GOOD BET FOR THE NRN HALF OF THE FA. HOWEVER...OWING TO MODEL
DIFFERENCES AND TO MAINTAIN CONSISTENCY WITH NEIGHBORING
OFFICES...I/VE ONLY GONE HIGH CHANCE POPS TUE AFTN...THOUGH I
SUSPECT THIS COULD VERIFY HIGHER.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
AS OF 1200 PM SAT...MODELS CONTINUE TO DIFFER WITH EACH OTHER...AND
RUN TO RUN...WITH THE EVOLUTION OF THE UPPER LOW OVER THE ERN STATES
DURING THE EXTENDED RANGE. INTERESTINGLY...THE 0600 UTC GFS LOOKED
ALMOST IDENTICAL TO YDAY/S ECMWF AS IT BROUGHT THE UPPER LOW FARTHER
SOUTH...DEVELOPING A SFC WAVE OVER THE EASTERN CAROLINAS THAT BROUGHT
A GOOD AMOUNT OF PCPN TO THE WRN CAROLINAS TUE NIGHT. HOWEVER THE
LATEST RUN OF THE EC IS NOW DIFFERENT AS IT KEEPS THE ENERGY FARTHER
TO THE EAST AND IS LARGELY DRY FOR THIS PERIOD. BY THE END OF THE
EXTENDED RANGE THE GFS HAS LIFTED THE FIRST LOW WELL TO THE NORTH OF
THE REGION...WITH PCPN FROM THE UPSTREAM KICKER ALREADY MOVING IN.
THE EC KEEPS THE WRN CONUS ENERGY MUCH FURTHER WEST AND ACTUALLY
DROPS THE ERN CONUS UPPER LOW BACK SOUTHWARD AGAIN FRI/SAT. THIS
WOULD KEEP US DRIER FOR NEXT WEEKEND...BUT MORE UNSETTLED THU/FRI.

THE BEST COURSE OF ACTION RIGHT NOW IS TO FOLLOW HPC. THEIR MODIFIED
HEIGHTS AND PRESSURES ARE MORE LIKE THE GFS THAN THE EC...THOUGH
IT/S SLOWER BRINGING THE ENERGY AT US FROM THE WEST. THERE IS STILL
A CHANCE FOR A MORE WIDESPREAD RAIN EVENT THAN WE ARE CURRENTLY
ADVERTISING FOR LATE TUE INTO WED...BUT CONFIDENCE REMAINS LOW. THE
WAY IT LOOKS NOW...ABOUT THE HIGHEST CONFIDENCE PART OF THE FORECAST
IS A DRY DAY FOR THU.

&&

.AVIATION /22Z SATURDAY THROUGH THURSDAY/...
AT KCLT...EXPECT DEEP CONVECTIVE ACTIVITY ACRS THE WESTERN FA AS OF
17 UTC TO CONTINUE TO EXPAND IN CVRG AND SHOULD BE SCATTERED ACRS THE
NC PIEDMONT LATER THIS AFTERNOON BEFORE DIURNAL DISSIPATION THIS
EVENING. GUIDANCE CONSENSUS FAVORS A PERIOD OF PRE-DAWN MVFR BR AND
JUST A SMALL CHANCE OF ANYTHING MORE THAN FEW MVFR LOW CLOUDS.
INCREASED MIXING SUNDAY MORNING SHOULD IMPROVE CONDS TO VFR BY
MID-MORNING WITH SW WINDS INCREASING TO 10 KTS BY MIDDAY.

ELSEWHERE...NUMEROUS SHOWERS AND SCATTERED THUNDERSTORMS ARE
EXPECTED ACRS THE FA BEFORE DIMINISHING THIS EVENING. THE GREATEST
CHANCE FOR OVERNIGHT FLIGHT RESTRICTIONS...MAINLY IN THE FORM OF
LOW CIGS...IS EXPECTED ACRS THE NC MTNS. MIXING TO INCREASE SUNDAY
MORNING TO MAINTAIN/REDEVELOP VFR CONDITIONS.

OUTLOOK...CIG AND VSBY RESTRICTIONS IN THUNDERSTORMS MOST NUMEROUS
OVER MOUNTAINS AND DURING AFTERNOONS AND EVENINGS THROUGH MID WEEK.
MORNING MVFR FOG POSSIBLE WHERE RAIN FELL THE NIGHT BEFORE.
