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 10, 10:47 PM EDT, 58 minutes earlier.

Area forecast discussion, May 10, 10:47 PM EDT, 58 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1047 PM EDT TUE MAY 10 2011

.SYNOPSIS...
AN UPPER LEVEL RIDGE WILL CONTINUE TO STRENGTHEN ACROSS THE EASTERN
HALF OF THE COUNTRY THROUGH WEDNESDAY. A WEAK BOUNDARY THROUGH
WESTERN NORTH CAROLINA INTO SOUTH CAROLINA WILL GRADUALLY MOVE
WESTWARD AND THEN DISSIPATE. A CLOSED UPPER LOW WILL SLOWLY APPROACH
THE AREA FROM THE WEST THIS WEEKEND.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
0300 UTC UPDATE...A NEW SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED
FOR BOWING THUNDERSTORMS MOVING SOUTH TOWARD INTO THE NORTHERN NC
MOUNTAINS. WEATHER GRIDS HAVE BEEN UPDATED TO MENTION DAMAGING WINDS
AND LARGE HAIL IN THE WATCH AREA.

PREVIOUS DISCUSSION...AN UPPER RIDGE AXIS EXTENDED FROM THE GULF
COAST TO THE GREAT LAKES THIS EVENING. A LOW MOVING WARM FRONT WAS
LOCATED FROM THE NORTHERN NC MOUNTAINS TO THE NORTHERN SC COAST. A
FIRST ROUND OF CONVECTION HAS WEAKENED AND MOVED SOUTHEAST OF OUR
AREA...BUT ADDITIONAL CONVECTION IN EASTERN KY IS MOVING THIS WAY
WITH A SECOND AND MORE VIGOROUS UPPER LEVEL IMPULSE. ALTHOUGH
INSTABILITY WILL BE DECREASING AS THE UPPER SYSTEM APPROACHES...BUT
ENOUGH SURVIVES TO WARRANT LIKELY POPS IN THE NORTHERN PORTION OF
THE AREA. IT REMAINS TO BE SEEN WHETHER A SECOND SEVERE THUNDERSTORM
WATCH WILL BE ISSUED FOR THIS SECOND ROUND OF CONVECTION LATE THIS
EVENING. MINIMUM TEMPERATURES WILL REMAIN RATHER MILD TONIGHT...
AROUND 10 DEGREES ABOVE NORMAL. FOG IS SUPPORTED BY GUIDANCE ACROSS
MUCH OF THE AREA BY DAYBREAK...MAINLY IN WESTERN NC AND THE SAVANNAH
RIVER VALLEY.

UPPER RIDGE AXIS OFF TO OUR WEST POKES A BIT FURTHER EASTWARD ON
WEDNESDAY AND DIURNAL DESTABILIZATION EXPECTED TO BE AT LEAST
MODERATE...ESPECIALLY WHERE TEMPERATURES WARM WELL INTO THE 80S ACRS
THE SW HALF OF THE CWFA. ALTHOUGH EFFECTIVE BULK SHEAR WILL BE
EXPECTEDLY LESS THAN WHAT WE ARE SEEING TODAY...ISOLATED...DIURNALLY
ENHANCED SVR STORMS WILL BE PROBABLE.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
AS OF 120 PM TUESDAY...A HIGH AMPLITUDE RIDGE WILL BREAK DOWN DURING
THIS SHORT TERM PERIOD OF THE FORECAST. SOME LEFT OVER CONVECTION
CARRYING INTO WEDNESDAY EVENING WITH THE NW FLOW AND THEN A DECREASE
THROUGH THURSDAY MORNING WITH THE RIDGE AXIS PASSING OVERHEAD.
GREATEST INSTABILITY SHOULD BE OVER NE GA AND THE WESTERN UPSTATE
WITH FAIRLY LIGHT WIND FIELDS.  NOT A BIG CONCERN AS OF THIS TIME.
HOWEVER...CONCERN PICKS UP AGAIN ON FRIDAY WITH LOW TO MID LEVEL
WIND FIELDS INCREASING LATE IN THE DAY AS COLD FRONT APPROACHES FROM
THE WEST.  CAPE VALUES VARY DEPENDING OF THE MODEL BUT MAINLY 1000
TO 1500 IN THE GA TO CAROLINA PIEDMONT. EXPECT INCREASING COVERAGE
OF SHOWERS AND STORMS LATE FRIDAY. HIGHS THURSDAY IN THE MID 80S
UPPER SAVANNAH TO THE LOWER TO MID 70S NEAR THE TRIAD. HIGHS FRIDAY
FROM LOWER 80S UPPER SAVANNAH TO UPPER 70S NW NC PIEDMONT.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AS OF 200 PM TUESDAY...NEW GUIDANCE CONTINUES TO SUPPORT AN
UNSETTLED WEATHER PATTERN FOR THE WEEKEND INTO THE FIRST PORTION OF
NEXT WEEK. BY EARLY IN THE WEEKEND...THE UPPER RIDGE WILL SHIFT EAST
OF THE AREA AS A CLOSED UPPER LOW MOVES SOUTHEAST FROM THE MIDWEST
INTO THE DEEP SOUTH BY MONDAY. LEANED HEAVILY ON HPC GUIDANCE WHICH
UTILIZED THE ECM/ECM ENSEMBLE MEAN EARLY ON THEN THE ECM/GFS
ENSEMBLE MEANS FOR THE LATE IN THE FORECAST PERIOD. WITH THE
SOUTHERN APPALACHIANS AND WESTERN CAROLINAS COMING UNDER INCREASING
UPPER DIVERGENCE DURING THE WEEKEND...THE LIKELY POPS SEEM
REASONABLE...WITH DAILY SOLID COVERAGE A GOOD BET THROUGH MON. A
GENERAL COOLING TREND IN TEMPERATURES IS ALSO EXPECTED DUE TO
WIDESPREAD CLOUDS/PRECIP AND LOWERING HEIGHTS.

&&

.AVIATION /03Z WEDNESDAY THROUGH SUNDAY/...
AT KCLT...CONVECTION AND ASSOCIATED RESTRICTIONS ARE STILL POSSIBLE
THIS EVENING AS UPPER SYSTEM INTERACTS WITH FRONT JUST NORTH OF THE
AIR FIELD...BUT WITH NO IMMEDIATE TREAT UPSTREAM...ONLY CB WILL BE
CARRIED IN THE TAF. GUIDANCE SHOWS WINDS TAKING ON A MORE
NORTHEASTERLY DIRECTION OVERNIGHT. SOME GUIDANCE SUPPORT FOR FOG BY
DAWN...BUT GUIDANCE HAS BEEN OVERLY AGGRESSIVE WITH FOG THE LAST FEW
NIGHT...AND VFR WILL BE MAINTAINED IN TAF...AS WILL A LOW VFR CIG.
CONVECTION WEDNESDAY AFTERNOON WILL BE TOO SCATTERED TO MENTION IN
THE TAF. LIGHT WINDS VEER TO ESE IN THE AFTERNOON.

ELSEWHERE...CONVECTIVE CHANCES WILL BE GREATEST FROM KAVL TO
KGSP/KGMU THIS EVENING...WHERE BETTER INSTABILITY EXISTS IN
PROXIMITY TO THE FRONT AND THE TRACK OF THE UPPER SYSTEM. WINDS ARE
EXPECTED TO TAKE ON A NORTHEASTERLY DIRECTION OVERNIGHT. GUIDANCE
SUPPORTS MVFR IN MUCH OF THE AREA AROUND DAWN...BUT RESTRICTIONS
WILL BE RESERVED FOR THE MOST PRONE AREAS OF WESTERN NC AND KAND.
TEMPORARY IFR VSBY WILL BE POSSIBLE AT KAVL. AFTERNOON CONVECTION ON
WEDNESDAY WILL BE ISOLATED TO SCATTERED...WITH CONFIDENCE TOO LOW TO
MENTION IN THE TAFS. LIGHT WINDS VEER TO SE IN THE
AFTERNOON...BECOMING S AT KAVL.

OUTLOOK...SCATTERED CEILING AND VISIBILITY RESTRICTIONS IN
THUNDERSTORMS MOST NUMEROUS OVER MOUNTAINS AND DURING AFTERNOONS AND
EVENINGS THROUGH END OF WEEK. MORNING MVFR FOG POSSIBLE WHERE RAIN
FELL THE NIGHT BEFORE.
