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 Feb 28, 2:43 PM EST, 2 hours 25 minutes earlier.

Area forecast discussion, Feb 28, 2:43 PM EST, 2 hours 25 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
243 PM EST MON FEB 28 2011

.SYNOPSIS...
A STRONG COLD FRONT WILL CROSS THE AREA AND MOVE OFF THE EAST COAST
TONIGHT. HIGH PRESSURE BUILDS IN BEHIND THE FRONT ON TUESDAY AND
REMAINS IN PLACE WEDNESDAY. A DRY COLD FRONT CROSSES THE AREA
WEDNESDAY NIGHT WITH ANOTHER HIGH PRESSURE BUILDING IN THROUGH THE
WEEKEND.

&&

.NEAR TERM /THROUGH TUESDAY/...
AS OF 130 PM...MAIN ACTION WILL BE IN THE FIRST 6 HOURS OR SO AS A
QLCS PRECEDING A SURFACE COLD FRONT MOVES QUICKLY ACROSS THE AREA.
CURRENTLY A BROKEN LINE IS STILL OVER EASTERN TN...BUT MESOSCALE
MODELS INDICATE THAT IT WILL BEGIN TO MOVE MORE RAPIDLY AND ENTER
GSP'S WESTERN NC COUNTIES BY 4PM...AND THEN QUICKLY MOVE ACROSS THE
REMAINDER OF THE FORECAST AREA BY 03Z. MODEL SOUNDINGS STILL DEPICT
A STRONG VEERING WIND FIELD ALOFT PRECEDING THE COLD FRONT AND
RESULTANT HIGH HELICITY. 50+KT JET EXTENDS BELOW 5KFT...SO MAIN
THREAT LOOKS TO BE LOCALIZED WIND DAMAGE WHERE CONVECTIVE ELEMENTS
OCCUR. HOWEVER...ISOLATED TORNADOES MAY ALSO OCCUR NEAR BREAKING
LINE SEGMENTS. THE LINE OF STORMS SHOULD CLEAR ALL OF THE AREA BY
MIDNIGHT WITH RAPID CLEARING OCCURRING BEHIND COLD FRONT...ALONG WITH A
PERIOD OF GUSTY POST FRONTAL NW WINDS.

SURFACE HIGH PRESSURE WILL CONTROL THE WEATHER ON TUESDAY RESULTING
IN ALMOST 100% INSOLATION AND TEMPS NEAR AVERAGE. USED A MOS BLEND
FOR TEMPS.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
AS OF 225 PM MONDAY...SHORT WAVES TO OUR NORTH DIG A LOW AMPLITUDE
TROF OVER THE EAST COAST TUE NITE AND WED. THE TROF MOVES OFF SHORE
AS A LOW AMPLITUDE RIDGE MOVES IN ON THU. AT THE SFC...DRY HIGH
PRESSURE OVER THE AREA TUE NITE GIVES WAY TO A DRY BACK DOOR COLD
FRONT WHICH MOVES THRU THE AREA WED NITE. SFC HIGH PRESSURE REMAINS
RIDGED INTO THE AREA THU. THE RESULTING SENSIBLE WX WILL BE
RELATIVELY QUIET WITH MAINLY CIRRUS CLOUDS AND BELOW NORMAL LOWS TUE
NITE AND ABOVE NORMAL HIGHS WED. WINDS WILL SHIFT TO THE NE AND BE
BREEZY AT TIMES WED NITE AND THU AS THE FRONT MOVES THRU. EXPECT A
SMALL INCREASE IN LOW CLOUDS LOW LEVEL SELY FLOW BRINGS IN SOME
MOISTURE...BUT BETTER LOW LEVEL MOISTURE MOVES IN LATER. THE WINDS
WILL KEEP THE ATMOS SOMEWHAT MIXED AND THE SCT CLOUDS WILL LIMIT
RADIATION WED NITE WITH LOWS ENDING UP A LITTLE ABOVE NORMAL. HIGHS
THU SHOULD BE NEAR TO ONLY SLIGHTLY ABOVE NORMAL WITH THE COOLER AIR
MASS MOVING IN.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
AS OF 240 PM MONDAY...THE MEDIUM RANGE FCST PICKS UP AT 00Z FRIDAY
WITH NEARLY FLAT/ZONAL H5 FLOW OVER THE AREA. MODELS DEVELOP ANOTHER
FAIRLY POTENT UPPER SHORTWAVE OVER THE CENTRAL ROCKIES LATE
FRI/EARLY SAT AND THEN TRANSLATE THE FEATURE EASTWARD. MODEL
SOLUTIONS BEGIN TO DIVERGE AT THIS POINT WRT THE AMPLITUDE AND SPEED
OF THE SHORTWAVE. THE LATEST 12Z GFS IS STILL CONSIDERABLY FASTER
AND LESS AMPLIFIED WHILE THE OLDER 00Z ECMWF LAGS BY NEARLY 24HRS
AND DEVELOPS A CLOSED H5 LOW BY EARLY SUNDAY AS THE DEEPER TROF
MOVES OVER THE SOUTHERN MISS RIVER VALLEY. AT THE SFC...HIGH
PRESSURE TO OUR NE IS EXPECTED TO MAINTAIN A BRIEF COLD AIR DAMMING
SCENARIO THROUGH FRIDAY. THE SFC PATTERN FOR THE REMAINDER OF THE
MEDIUM RANGE...THROUGH THE WEEKEND...REMAINS UNCLEAR WITH OVERALL
LOW CONFIDENCE IN THE SENSIBLE FCST. THE FASTER GFS DEVELOPS A
SOUTHERN PLAINS SFC LOW AND MOVES A COLD FRONT OVER THE FCST AREA
LATE SAT/EARLY SUN...WHILE THE ECMWF DEVELOPS A LOW FARTHER SE AND
DOES NOT PUSH A FRONT THROUGH UNTIL LATE SUN. THE EC ALSO HAS SOME
HEALTHY LOOKING WRAP AROUND MOISTURE OVER WESTERN NC AND EXTREME NE
GA EARLY MON. ONCE THE LOW FINALLY CLEARS THE REGION...THINGS SHOULD
DRY OUT FOR THE REMAINDER OF THE PERIOD. HPC CONTINUES TO FAVOR THE
ECMWF SOLUTION MORE AND KEEPS AT LEAST CHANCE POPS OVER MUCH OF THE
CWFA THRU EARLY MONDAY. IF THE EC SOLUTION DOES WORK OUT...WE CAN
EXPECT MOST OF THE PRECIP TO FALL ON SUN WITH THE FROPA. TEMPS
SHOULD REMAIN BELOW CLIMO ON FRI WITH THE WEDGE IN PLACE AND WARM TO
A FEW DEGREES ABOVE NORMAL OVER THE WEEKEND AS THE WEDGE ERODES.

&&

.AVIATION /20Z MONDAY THROUGH SATURDAY/...
AT KCLT...DEEP MIXED LAYER PROMOTING STIFF SW WINDS WITH GUSTS TO
AROUND 30KT THROUGH THE AFTERNOON. MAIN WEATHER EVENT FOR THE
AIRFIELD WILL BE THE PASSAGE OF A COLD FRONT ACCOMPANIED BY A LINE
OF THUNDERSTORMS EARL;Y THIS EVENING. EXPECT A PERIOD OF THUNDER/LOW
MVFR CONDTIONS FROM ABOUT 23Z-01Z WITH THE FRONTAL PASSAGE AND
PERHAPS A PEAK NW GUST IN EXCESS OF 40KT. EXPECT RAPID IMPROVEMENT
(TO VFR) BY 05Z WITH WINDS VEERING TO THE NW AND THEN TO THE NE
AROUND 12Z TUE.

ELSEWHERE...NEARLY THE SAME STORY WITH STRONG SW WINDS THIS
AFTERNOON. EXPECT FRONTAL PASSAGE ACCOMPANIED BY THUNDER/LOW MVFR
CONDITIONS IN THE 22Z-01Z TIMEFRAME. SOME WIND SHEAR INDICATED
ACROSS UPSTATE SC LATE THIS AFTERNOON. COULD SEE A PEAK NW GUST WITH
THE FRONTAL PASSAGE IN EXCESS OF 40KT. RAPID IMPROVEMENT EXPECTED BY
05Z (VFR) WITH WINDS VEERING TO THE NW AND THEN NE ON TUE.

OUTLOOK...A DRY HIGH PRESSURE WILL DOMIANTE THRU THU. MOISTURE WILL
RETURN TO THE AREA LATE IN THE WEEK AS A FLOW OFF THE ATLANTIC DEVELOPS.
