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 8, 2:57 PM EDT, 3 hours 17 minutes earlier.

Area forecast discussion, Aug 8, 2:57 PM EDT, 3 hours 17 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
257 PM EDT MON AUG 8 2011

.SYNOPSIS...
A WEAK FRONTAL BOUNDARY ALONG WITH A HOT AND HUMID AIRMASS WILL
LINGER ATOP THE REGION INTO TUESDAY. DRIER HIGH PRESSURE WILL BUILD
OVER THE AREA ON WEDNESDAY. ANOTHER FRONT WILL ENTER THE AREA ON
SATURDAY, BRINGING A CHANCE FOR RAIN AND THUNDERSTORMS.

&&

.NEAR TERM /THROUGH TUESDAY/...
THE NEXT 24 HOURS SHOULD BE CONVECTIVELY ACTIVE...WITH ONE BROKEN
LINE OF CONVECTION CONSOLIDATING IN ERN TN/WRN NC AT 19Z AND THE
POSSIBILITY OF MORE LATE TONIGHT. HAVE DRAMATICALLY RAISED THE POP
OVER THE MTNS TO DEAL WITH THE CONVECTIVE TREND. EAST OF THE MTNS
THE PICTURE IS NOT AS CLEAR AS THE AIR MASS IS NOT AS FAVORABLE
OWING TO DEWPT IN THE LOW/MID 60S...SO THERE MIGHT BE SOME STRUGGLE
TO MAINTAIN IT OFF THE BLUE RIDGE. THE NAM AND 4KM WRF SUGGEST THAT
LOW LEVEL CONVERGENCE IN THE WNW FLOW WILL MAINTAIN THE CONVECTION
DOWN ACROSS THE I-26/I-385 CORRIDOR...SO HAVE INCREASED THE POP
THERE AS WELL. OVER TOWARD I-77...NOT SO MUCH. SOME STRONGER MID
LEVEL FLOW WILL SUPPORT A WIND DAMAGE THREAT INTO THE EVENING. TEMP
TRENDS HAVE NOT KEPT UP WITH THE PREVIOUS FCST...SO A HEAT ADVISORY
SEEMS LESS LIKELY FOR THE LATE AFTERNOON.

OVERNIGHT...THE MODELS ARE SUGGESTING THAT ANOTHER MCS WILL DEVELOP
UPSTREAM OVER THE OZARKS OR MID MS VALLEY LATER THIS EVENING...AND
THAT IT WILL MAKE A RUN AT THE MTNS LATE TONIGHT. WILL ALLOW THE POP
TO WANE THIS EVENING AS THE FIRST CONVECTIVE LINE LEAVES...BUT WILL
RETAIN THE CHANCE POP ON THE TN BORDER IN CASE THIS WORKS OUT. MIN
TEMPS WERE KEPT ABOVE GUIDANCE...ESPECIALLY WITH THE POSSIBILITY OF
PLENTY OF CONVECTIVE DEBRIS CLOUDS.

ON TUESDAY...IF THERE ARE NO CONVECTIVE REMNANTS...AN MCV IS A VERY
REAL POSSIBILITY. WE REMAIN UNDER A BROAD UPPER TROF THAT IS
GENERALLY FAVORABLE WITH SOME WEAK UPPER Q CONVERGENCE. ALMOST THE
ENTIRE FCST AREA IS IN THE SLIGHT RISK BECAUSE OF THIS AND THE
STRONGER MID LEVEL FLOW. THE SREF HAS A VERY HIGH POP FOR THE
AFTERNOON SO SOME UPWARD ADJUSTMENT WAS MADE. TEMPS WERE NUDGED
TOWARD A GUIDANCE BLEND.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
AS OF 2 PM MONDAY...THE SHORT TERM FCST PICKS UP AT 00Z ON WEDNESDAY
WITH THE AXIS OF THE GREAT LAKES H5 TROF ORIENTED N/S JUST TO OUR
WEST. THE MODELS SUGGEST THAT SOME SORT OF WEAK H5 SHORTWAVE WILL BE
MOVING OVER THE FCST AREA AT THE BEGINNING OF THE PERIOD FOLLOWED BY
A SERIES OF ADDITIONAL UPPER SHORTWAVES TRANSLATING OVER THE REGION
LATE WED AND INTO THURS. HEIGHTS BEGIN TO SLOWLY RISE AGAIN TOWARDS
THE END OF THE PERIOD AS THE WEST CONUS H5 RIDGE MODERATELY
BUILDS. LATE TUES AND EARLY WEDNESDAY...THE LOW LVL FRONTAL
BOUNDARY SHOULD MOVE SE OF THE CWFA AND USHER IN DRIER NWLY FLOW.
GREATEST CHANCE FOR ANY WIDESPREAD CONVECTION WILL BE DURING THE
FIRST 6 HRS OR SO OF THE PERIOD WITH THE BOUNDARY LAYER PW VALUES
DROPPING FAIRLY QUICKLY AFTER 06Z. EXPECT MOSTLY DRY CONDITIONS WITH
MODERATE DOWNSLOPE FLOW AND JUST A SLIGHT CHANCE POP OVER THE
NORTHERN AND CENTRAL NC MTS DURING THE DAY/EVENING. HIGHS WILL BE A
BIT COOLER BUT STILL PROGGED TO REACH THE MID 90S OVER THE LOWER
ELEVATIONS. ON THURS...THE CENTER OF THE SFC HIGH WILL SLIDE JUST TO
OUR NORTH PROVIDING MORE NORTHERLY LOW LVL FLOW AND BRINGING TEMPS
DOWN A FEW MORE DEGREES TO THE LOWER 90S OVER THE PIEDMONT AND
FOOTHILLS. I KEPT A SLIGHT CHANCE OVER THE WESTERN NC MTS AND FAR NE
GA ZONES FROM ABOUT NOON TO 7PM...HOWEVER PROFILES MAY BE TOO DRY TO
SEE ANY PRECIP.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
AS OF 3 PM MONDAY...A BLEND OF THE ECMWF AND GFS WILL BE USED FOR
THE EXTENDED RANGE FORECAST. A LONG WAVE TROF WILL REMAIN EAST OF
THE MISSISSIPPI RIVER VALLEY THROUGH THE LATE WEEK AND WEEKEND. ON
FRIDAY...MID LEVEL HEIGHTS REMAIN SLIGHTLY NORTHWEST WITH WEAK HIGH
PRESSURE CENTERED OVER THE MID ATLANTIC STATES. BASED ON THE LLVL
THICKNESSES AND DECENT INSOLATION IT APPEARS THAT HIGH TEMPERATURES
WILL REMAIN A FEW DEGREES ABOVE NORMAL. FORECAST SOUNDINGS INDICATE
THAT GREATEST POTENTIAL INSTABILITY WILL OCCUR ACROSS THE UPPER
SAVANNAH RIVER VALLEY AND THE UPSTATE OF SC. I WILL ADVERTISE SCHC
POPS FOR AFTERNOON AND EVENING TSRA.

SATURDAY AND SUNDAY...A NOTABLE S/W WILL DIVE ACROSS THE MID WEST
AND OHIO RIVER VALLEY...POSSIBLY MOVING ACROSS THE REGION ON SUNDAY.
FORECAST SOUNDINGS INDICATE WIDESPREAD WEAK INSTABILITY EACH
AFTERNOON AND EVENING. BASED ON THE SIGNIFICANT S/W...INCREASING
WIND FIELDS...AND WIDESPREAD INSTABILITY IT APPEARS THAT 30 TO 50
POPS ARE JUSTIFIED EACH DAY. ON MONDAY...MID LEVEL TROF AXIS APPEARS
TO AMPLIFY ACROSS THE REGION WITH SOME WRAP AROUND MOISTURE. BASED
ON NATIONAL GUIDANCE AND MID LEVEL PATTERN IT APPEARS THAT AT LEAST
SCHC POPS ARE REASONABLE DURING THE AFTERNOON AND EVENING.
TEMPERATURES SHOULD RANGE AROUND NORMAL THROUGH THE WEEKEND INTO
MONDAY.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
AT KCLT...VFR CONDITIONS THROUGH THE PERIOD. FOR THIS AFTERNOON AND
EVENING...MAINLY A WIND FCST. TCLT RADAR WIND PROFILE SHOWS NW IN
THE BOUNDARY LAYER SO EXPECT NW WINDS TO CONTINUE AT THE SFC FOR AT
LEAST THE REMAINDER OF THE DAYLIGHT HOURS. FOR CLOUDS...ONLY A FEW
HIGH-BASED STRATOCU TO DEAL WITH...ALTHO THERE IS A VERY REMOTE
POSSIBILITY OF A SHOWER LATE THIS AFTERNOON. AM WATCHING CONVECTION
MOVING ACROSS ERN TN WITH SOME INTEREST. WESTERLY WIND ALOFT IS LESS
FAVORABLE FOR IT REACHING THE PIEDMONT. THERE IS A LOW CHANCE OF ANY
RESTRICTIONS IN THE MORNING. SOME CONVECTIVE DEBRIS CLOUDS SHOULD
ROLL IN AFTER SUNRISE TUESDAY. THINK ANY DEEPER CONVECTION WILL
PROBABLY HOLD OFF UNTIL AFTER THE END OF THE TAF PERIOD.

ELSEWHERE...GENERALLY A WESTERLY COMPONENT TO THE WIND THIS
AFTERNOON...FUNNELLED BY THE TERRAIN. CONVECTION OVER ERN TN WILL BE
WATCHED FOR IMPACT AT KAVL AND OTHER TAF SITES AND WILL AMEND
ACCORDINGLY. THE BEST CHANCE MIGHT BE AROUND KGSP AROUND 21Z AS
CONVERGENCE IN WNW FLOW MAY AID THE REDEVELOPMENT OF THE
CONVECTION...AS SHOWN BY THE NAM AND WRF-NMM MODELS. FOR NOW...WILL
LEAVE IT OUT. LATER TONIGHT A MORE ORGANIZED AREA OF SHRA/TSTMS MAY
MOVE INTO THE MTNS. SOME FOG IS POSSIBLE AT KAVL AROUND SUNRISE.
THERE SHOULD BE MORE CONVECTIVE DEBRIS CLOUDS AFTER SUNRISE TUESDAY.

OUTLOOK...MOISTURE WILL GRADUALLY DIMINISH EARLY NEXT WEEK IN
PERSISTENT WESTERLY FLOW. STILL EXPECT ISOLD-SCT SHWRS/TSTMS THRU
THE PERIOD.
