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 Aug 9, 9:42 PM EDT, 32 minutes earlier.

Area forecast discussion, Aug 9, 9:42 PM EDT, 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
942 PM EDT TUE AUG 9 2011

.SYNOPSIS...
A WEAK FRONTAL BOUNDARY ALONG WITH A HOT AND HUMID AIRMASS WILL
LINGER OVER THE REGION THROUGH TONIGHT. A RIDGE OF HIGH PRESSURE
WITH DRIER AIR WILL BUILD BACK OVER THE AREA ON WEDNESDAY.
ANOTHER FRONT WILL ENTER THE AREA ON SATURDAY...BRINGING A CHANCE
FOR RAIN AND THUNDERSTORMS ALONG WITH COOLER TEMPERATURES.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
CONVECTION HAS DIMINISHED WITH COOLING AND STRONGER STORMS WILL
REMAIN WELL S OF THE AREA BEFORE ENDING LATE. HELD ON TO SLIGHT CHC
POPS OVER MTNS AND S CWA TIL 2AM. LOOK FOR PCLDY TO MCLDY SKIES
BECMG MCLR OVERNIGHT. TWEAKED SKY COVER...POPS AND TEMPS USING
LATEST TRENDS/GUIDANCE.

ON WEDNESDAY...WE REMAIN AT THE BOTTOM OF THE UPPER LONG WAVE TROF
CENTERED OVER THE EASTERN PART OF THE COUNTRY. DEEP LAYER DRYING AND
WARMER AIR ALOFT WILL SERIOUSLY CURTAIL OUR CONVECTIVE PRECIP
CHANCES SO HAVE FOLLOWED THE SREF AND KEPT THE FCST AREA DRY. TEMPS
WILL BE ABOUT THE SAME AS TODAY WITH MORE SUN...BUT LOWER DEWPOINTS.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
AS OF 130 PM TUESDAY...THE SHORT TERM FCST PICKS UP AT 00Z ON
THURSDAY WITH THE AXIS OF THE GREAT LAKES UPPER TROF TO OUR NORTH
WITH NUMEROUS SHORTWAVES MOVING INTO THE REGION FROM THE WEST. THE
UPPER TROF BEGINS TO LIFT NORTHWARD ON THURS AS THE UPPER RIDGE
SLOWLY BUILDS TO OUR WEST. LATE WEDNESDAY INTO THURSDAY...THE
FRONTAL BOUNDARY WILL BE TO OUR SE BY LATE WED WITH COOLER AND DRIER NW FLOW
IN ITS WAKE. AS THE SFC HIGH BEGINS TO MOVE EASTWARD...LOW LVL FLOW
WILL QUICKLY BECOME NORTHERLY AND THEN TRANSITION TO LIGHT AND
VARIABLE BY THURS AFTERNOON. MODELS CONTINUE TO SUGGEST THAT A WEAK
MESO LOW COULD DEVELOP JUST TO OUR EAST WITH SOME SORT OF
MCS/MCV...ASSOCIATED WITH AN UPPER LVL SHORTWAVE...DEVELOPING OVER
TENN AND ADVECTING INTO OUR CWFA BY LATE AFTERNOON. RIGHT
NOW...MODELS SOUNDINGS DO HAVE SOME SFC BASED INSTABILITY AND SMALL
AMOUNTS OF HELICITY BUT IT PROBABLY WONT BE ENOUGH TO PRODUCE ANY
SVR CONVECTION. TEMPS SHOULD BE A FEW DEGREES COOLER THAN THE
PREVIOUS DAY WITH HIGHS IN THE LOWER 90S. ON FRIDAY...THE CENTER OF
THE SFC HIGH WILL SLIDE FARTHER EAST WITH MOSTLY LIGHT AND VRB WINDS
NEAR THE SFC. EXPECT PROFILES TO BE DRIER OVER THE FCST AREA...BUT
WITH BETTER INSTABILITY THE POTENTIAL FOR PULSE TYPE SVR CONVECTION
SHOULD BE GREATER. TEMPS ARE EXPECTED TO BE VERY SIMILAR TO THE
PREVIOUS DAY WITH HIGHS NEAR CLIMO...IF NOT A DEGREE OR 2 ABOVE.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AS OF 130 PM TUESDAY...THE MEDIUM RANGE MODELS ARE IN GOOD AGREEMENT
WITH THE MID LEVEL PATTERN LATE THIS WEEK...INDICATING A L/W RIDGE
ACROSS THE ROCKIES AND A DIGGING TROF ACROSS THE GREAT LAKES REGION.
BROAD LIFT ASSOCIATED WITH THE APPROACHING MID LEVEL TROF WILL
INCREASE ACROSS THE CWA THROUGH THE DAY ON SATURDAY. FORECAST
SOUNDINGS INDICATE THAT DECENT LAPSE RATES WILL DEVELOP BETWEEN THE
SFC AND H5 AS THE TROF APPROACHES AND THE CWA REMAINS IN THE WARM
SECTOR...WITH CAPE VALUES AROUND 1K J/KG. GIVEN THE LARGE SCALE LIFT
AND ADEQUATE INSTABILITY I WILL MAINTAIN A DEVELOPING SOLID CHC POPS
ACROSS THE CWA SATURDAY AFTERNOON AND EVENING.

THE PEAK OF THE MID LEVEL LIFT IS EXPECTED TO MOVE ACROSS THE
SOUTHERN APPALACHIAN REGION SATURDAY NIGHT. FORECAST SOUNDINGS
CONTINUE TO INDICATE FAIRLY STEEP LAPSE RATES AND ELEVATED
INSTABILITY DURING THE NIGHT. CONVECTION THAT INITIATES OVER THE
REGION ON FRIDAY WILL LIKELY PERSISTS OVER THE CWA THROUGH THE
NIGHT. IN FACT...GIVEN THE DEGREE AND DURATION OF THE LIFT AND
INCREASING STEERING FLOW IT APPEARS THAT SHRA/TSRA COVERAGE WILL
INCREASE DURING THE NIGHT. I WILL INCREASE POPS TO HIGH CHC NORTH TO
SOLID CHC SOUTH. A SIGNIFICANT SFC FRONT IS EXPECTED TO SWEEP WEST
TO EAST ACROSS THE REGION SUNDAY MORNING. BY DAYBREAK SUN...THE FRONT MAY
RUN ALONG THE EAST FACING SLOPES OF THE MTNS. AREAS ALONG AND AHEAD
OF THE FRONT MAY DEVELOP STEEP LAPSE RATES...AROUND 9C/KM BETWEEN
THE SFC AND H7. I WILL MAINTAIN HIGH CHC POPS DURING THE MORNING AND
INDICATE DECREASING POPS THROUGH THE DAY AS THE FRONT PUSHES EAST.

ON MONDAY...0Z ECMWF IS CONSIDERABLY SLOWER THE GFS. USING A BLEND
OF BOTH SOLUTIONS...LINGERING MOISTURE AND WEAK INSTABILITY MAY
SUPPORT A FEW SHRA/TSRA. I WILL KEEP A DIURNAL SCHC POP ACROSS THE
REGION. ON TUESDAY...THE ATMOSPHERE WILL DRY AS LARGE HIGH PRESSURE
PIVOTS OVER THE MID ATLANTIC REGION. LLVL WINDS SHOULD BECOME
EAST...RESULTING IN A LARGE AREA OF UPSLOPE FLOW ACROSS THE MTNS.
WEAK INSTABILITY...UPSLOPE FLOW...AND RIDGETOP CONVERGENCE MAY YIELD
A FEW HIGH TERRAIN SHRA/TSRA DURING THE AFTERNOON AND EARLY EVENING.
I WILL INDICATE SCHC POPS ACROSS THE MTNS AND DRY CONDITIONS EAST.

TEMPERATURES ACROSS THE CWA MAY BEGIN THE PERIOD ON SATURDAY
SLIGHTLY BELOW NORMAL AND END THE PERIOD AROUND NORMAL ON TUESDAY.

&&

.AVIATION /02Z WEDNESDAY THROUGH SUNDAY/...
AT KCLT AND ELSEWHERE...CONVECTION WILL STAY WELL S OF ALL TERMINALS
BEFORE COOLING AND DISSIPATING LATE THIS EVE. LGT W-NW WINDS WILL
BECOME NLY OVERNIGHT...THEN INCREASE WED AFTN. A LEE TROF WILL BRING
WINDS AROUND TO THE SW IN THE SC PIEDMONT WED AFTN.

OUTLOOK...VFR WED NIGHT. SCT TSTMS PSBL OVER MTNS THU AFTN-EVE. DRY
AGAIN FRI. INCRSNG CHC TSTMS LATE SAT-SUN.
