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 14, 2:30 PM EDT, 1 hour 3 minutes earlier.

Area forecast discussion, Aug 14, 2:30 PM EDT, 1 hour 3 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
230 PM EDT SUN AUG 14 2011

.SYNOPSIS...
A COLD FRONT WILL MOVE SOUTHEAST OF THE AREA TONIGHT. COOLER HIGH
PRESSURE WILL THEN GRADUALLY BUILD ACROSS THE AREA FROM THE WEST
EARLY IN THE WEEK. ANOTHER WEAK COLD FRONT WILL APPROACH THE AREA BY
THE END OF THE WORK WEEK.

&&

.NEAR TERM /THROUGH MONDAY/...
CONVECTION RAPIDLY INCREASING ACROSS THE AREA AS UPPER TROF AND SFC
FRONT MOVE IN FROM THE WEST. WITH MODERATE INSTABILITY AND 30 KTS OF
SHEAR...SVR STORMS ARE INCREASINGLY LIKELY. THEREFORE...A WATCH HAS
BEEN POSTED FOR THE CWFA. DOWNBURST WINDS ARE STILL THE MAIN THREAT
BUT LARGE HAIL IS ALSO POSSIBLE. GIVEN THE STORM MOVEMENT...FLOODING
IS LESS LIKELY. HOWEVER...ANY TRAINING CELLS OR HEAVY RAIN IN AREAS
THAT HAD HEAVY RAIN THE PAST FEW DAYS...COULD CREATE ISOLATED
FLOODING. STORMS SHOULD DIMINISH FROM WEST TO EAST LATE AFT/EARLY EVE
AS THE SHORT WAVE/FRONT MOVE EAST OF THE AREA. HOWEVER...SHOWERS
COULD LINGER OVER THE NC MTNS AS LOW LEVEL FLOW BECOMES NWLY AND LOW
LEVEL MOISTURE LINGERS THERE. A COOLER AIR MASS MOVES IN BEHIND THE
FRONT SO LOWS END UP A FEW DEGREES BELOW NORMAL.

OVERALL DRIER AIR MOVES IN FOR MONDAY. HOWEVER...LOW LEVEL MOISTURE
WILL LINGER...ESP ACROSS NC. EXPECT ISOLATED SHOWERS TO DEVELOP OVER
THE MTNS BY AFTERNOON AS ADDITIONAL SHORT WAVE ENERGY ROTATES THRU
THE UPPER TROF. SOME OF THIS CONVECTION COULD MOVE OUT OF THE MTNS
AND ACROSS THE I-40 CORRIDOR DURING THE AFTERNOON. AT THE LEAST...
CLOUDS SHOULD INCREASE OVER THAT AREA. NLY FLOW OVER THE UPSTATE AND
NE GA SHOULD PRECLUDE ANY CONVECTION AND KEEP CLOUDS TO A MINIMUM.
WITH LOWER THICKNESSES...HIGHS WILL BE 5 DEGREES BELOW NORMAL OVER
THE MTNS AND A LITTLE BELOW NORMAL ELSEWHERE.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
AS OF 130 PM SUNDAY...THE SHORT TERM FCST PICKS UP AT 00Z ON TUESDAY
WITH THE AXIS OF THE H5 TROF JUST TO OUR NE AND AN UPPER RIDGE
PUSHING FARTHER EAST AND INTO THE SE CONUS. WE CAN EXPECT HEIGHTS TO
RISE QUICKLY ACROSS THE FCST AREA ON TUES AND THEN LEVEL OFF TO SOME
DEGREE ON WED AS THE LARGE SCALE UPPER PATTERN FLATTENS.

ON TUESDAY...SFC HIGH PRESSURE WILL BUILD OVER THE AREA AS THE
DEPARTING LOW MOVES FARTHER UP THE NEW ENGLAND COAST. COOLER AND
DRIER NWLY LOW LVL FLOW WILL PERSIST OVER THE CWFA INTO WED BRINGING
MORE COMFORTABLE TEMPS AND DEWPTS AND A LACK OF SH AND TS. THE ONLY
EXCEPTION MIGHT BE OVER THE NC/TN BORDER WHERE SOME LINGERING LOW
LVL MOISTURE COULD RING OUT A FEW SHOWERS. HIGH TEMPS ARE PROGGED TO
BE A BIT BELOW CLIMO WITH HIGHS IN THE UPPER 80S TO NEAR 90 FOR THE
LOWER ELEVATIONS AND LOWER 80S FOR THE MTS. ON WEDNESDAY...THE SFC
HIGH WILL SLOWLY SLIDE EAST AND EVENTUALLY BECOME ABSORBED INTO THE
BERMUDA HIGH LATER IN THE MEDIUM RANGE. LOW LVL FLOW WILL VEER
AROUND TO THE EAST BY MIDDAY CREATING SOME WEAK UPSLOPE FLOW AND A
SLIGHTLY BETTER CHANCE FOR PRECIP...HOWEVER MODEL PROFILES LOOK
PRETTY DRY AT THIS POINT AND THERE IS NOT ANY APPRECIABLE UPPER SUPPORT
TO GENERATE LIFT...SO I KEPT THE FCST DRY THRU 00Z THURS. TEMPS
SHOULD BE VERY SIMILAR TO THE PREVIOUS DAY WITH HIGHS A DEGREE OR 2
WARMER.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
AT 2 PM EDT SUNDAY...AN ANOMALOUS MEAN UPPER TROUGH WILL PERSIST
ALONG THE EASTERN SEABOARD FROM WEDNESDAY NIGHT THROUGH SUNDAY.
UNSEASONABLY STRONG HEIGHT FALLS WILL OCCUR ON THURSDAY AS AND UPPER
LOW REACHES EASTERN CANADA...AND ASSOCIATED SHORTWAVE ENERGY MOVES
SOUTHEAST TOWARD THE APPALACHIANS. THE TROUGH DEAMPLIFIES SLIGHTLY
BY LATE IN THE WEEK...BEFORE ANOTHER UPPER LOW MOVES INTO EASTERN
CANADA...BRINGING ANOTHER ROUND OF HEIGHT FALLS TO THE EASTERN USA.
WEAKENING HIGH PRESSURE WILL REMAIN ALONG THE EAST COAST. THIS AIR
MASS WILL INITIALLY BE DRY...BUT AS LOW LEVEL FLOW VEERS FROM NE TO
SE AND THEN TO S...ATLANTIC MOISTURE WILL CREEP WEST AND NORTH TO
THE BLUE RIDGE...WHERE UPSLOPE FLOW WILL FAVOR INCREASING POPS. IN
ADDITION...THE REMAINS OF A COLD FRONT WILL ARRIVE WITH MORE
MOISTURE LATE IN THE WEEK. TEMPERATURES WILL BE A CATEGORY OR SO
BELOW NORMAL UNDER THE UPPER TROUGH.

&&

.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
AT KCLT AND ELSEWHERE...CONVECTION WILL AGAIN BE THE MAIN CONCERN IN
THE NEAR TERM. CB SHOULD FILL IN FROM WEST TO EAST THIS AFTERNOON
AND HAVE GONE WITH THIS TIMING. W TO SW WINDS CONTINUE THIS
AFTERNOON THEN SHIFT TO NW THIS EVENING WHEN CONVECTION DIMINISHES.
WIND BECOMES LIGHT N OVERNIGHT WITH KAVL/KHKY THE LOCATIONS WITH THE
BEST CHC FOR ANY RESTRICTIONS. CANNOT BE RULED OUT ELSEWHERE. ANY
FOG/LOW CLOUDS SHOULD RAPIDLY IMPROVE MON MORN AS DRIER AIR MOVES IN
AND NLY FLOW INCREASES. LOW VFR CIGS POSSIBLE ACROSS THE NC SITES
FOR THE EARLY AFTERNOON AS CLOUDS FORM OVER THE MTNS AND SPREAD EWD.

OUTLOOK...EXPECT DRIER WEATHER TUE-WED. CHANCE OF CONVECTION WILL
INCREASE AGAIN THU AS ANOTHER SYSTEM APPROACHES FROM THE W.
