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 Jun 22, 4:36 PM EDT, 1 hour 34 minutes earlier.

Area forecast discussion, Jun 22, 4:36 PM EDT, 1 hour 34 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
436 PM EDT WED JUN 22 2011

.SYNOPSIS...
A WEAK COLD FRONT WILL MOVE ACROSS THE AREA LATE TONIGHT INTO
THURSDAY. THE FRONT IS EXPECTED TO STALL JUST SOUTH OF THE AREA
THURSDAY NIGHT. WEAK HIGH PRESSURE WILL DEVELOP NORTHWEST OF THE
AREA ON FRIDAY MOVE TO THE NORTH OF THE AREA THIS WEEKEND. THE
LINGERING FRONT WILL KEEP THE WEEKEND UNSETTLED...MAINLY ACROSS
SOUTH CAROLINA AND NORTHEAST GEORGIA.

&&

.NEAR TERM /THROUGH THURSDAY/...
AT 2030Z...FCST UPDATE TO FOCUS ON INCREASED TSTM PROBABILITIES INTO
THE EARLY EVENING HOURS AS WIDESPREAD NORTH AND CENTRAL GEORGIA
ACTIVITY PROPAGATES ENEWARD. COLD POOL AIDED DEEP CONVECTION WILL
REMAIN LIKELY...ESPECIALLY INTO NE GA AND THE WESTERN UPSTATE WHERE
CHANCES FOR LOCALLY DAMAGING WIND GUSTS WILL BE SEEN WITHIN
CLUSTERS...LEWPS AND BOWS.

PREVIOUS DISCUSSION...
THE NEAR TERM PERIOD WILL SEE AN UPPER TROUGH BECOME
ESTABLISHED OVER THE EASTERN U.S. WITH AN UPPER LOW CENTERED OVER
THE GREAT LAKES. AS THIS OCCURS...A WEAK SURFACE COLD FRONT AND
ATTENDANT MOISTURE BAND WILL MOVE FROM WEST TO EAST ACROSS THE
REGION. THERE ARE TIMING DIFFERENCES AMONG THE MODELS WITH THIS
FEATURE WITH THE NAM THE SLOWEST AND THE GFS FASTER. ACTUALLY THE
SREF IS CLOSER TO THE FASTER GFS...SO THIS GIVES SOME SUPPORT
UTILIZING THE FASTER GFS TIMING.

IN REGARD TO SENSIBLE WEATHER...INSTABILITY RAMPING UP ACROSS THE
FORECAST AREA WITH LAPS CAPES OUTSIDE THE MOUNTAINS IN THE
1500-2000J RANGE...EXTENDING INTO THE WESTERN NC MOUNTAINS.
MESOSCALE MODELS LIKE HRRR AND LOCAL WRF ARW DEVELOP WIDELY
SCATTERED TO SCATTERED THUNDERSTORMS DURING THE LATE AFTERNOON
HOURS. WITH DCAPES OVER 1000J CAN'T RULE OUT A COUPLE ISOLATED
SEVERE STORMS...BUT IT SHOULD NOT BE ANYTHING LIKE TUE EVENING.
APART FROM THE INSTABILITY CONVECTION LATE THIS AFTERNOON AND
EVENING...THE GFS DEPICTS A SHORT WAVE MOVING THROUGH THE AREA
OVERNIGHT. THIS APPEARS TO BE CONNECTED WITH THE CONVECTIVE CLUSTER
CURRENTLY OVER EASTERN MS AT MID AFTERNOON. THE UPSHOT IS THAT WE
EXPECT ANOTHER ROUND OF CONVECTION IN THE 02Z-08Z TIMEFRAME. HENCE
WILL MAINTAIN RATHER ROBUST POPS TONIGHT...WITH HIGHEST CONFIDENCE
OVER WESTERN AREAS. FRONT MOVES ACROSS THE AREA THU MORNING. BEST
MOISTURE AND WEAK FORCING OVER THE UPSTATE SHOULD PRODUCE SCATTERED
AFTERNOON CONVECTION...WITH WEAK DOWNSLOPE WINDS DRYING THINGS OUT
LATE. CAN'T RULE OUT WIDELY SCATTERED SHOWERS/THUNDERSTORMS IN THE
MOUNTAINS LATE IN THE DAY AS ANOTHER SHORT WAVE APPROACHES. MAX
TEMPS ON THU WILL BE CLOSE TO SEASONAL LEVELS USING A MOS BLEND
APPROACH.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
AS OF 130 PM WEDNESDAY...THE SHORT TERM FCST PICKS UP AT 00Z ON
FRIDAY WITH THE UPPER TROF CENTERED OVER THE GREAT LAKES REGION AND
AN UPPER RIDGE MOVING INTO THE NORTHERN PLAINS BEHIND THE TROF. OVER
THE NEXT 48 HRS OR SO...THE UPPER TROF WILL LIFT TO THE NE AND
DEAMPLIFY AS THE UPPER RIDGE SLIDES FARTHER EAST.

LATE THURSDAY AND INTO FRIDAY...A COLD FRONT WILL MOVE OVER THE FCST
AREA FROM THE WEST THURS AND THURS NIGHT AND THEN STALL OUT AS IT
REACHES THE COAST. ALTHOUGH SOME DRYING IS EXPECTED BEHIND THE
FRONT...BOUNDARY LAYER WINDS SHOULD REMAIN WEST TO SWLY UNTIL
SATURDAY AND KEEP SOME FAIRLY DECENT LOW LVL MOISTURE OVER THE AREA.
THAT COUPLED WITH HEALTHY INSTABILITY OVER MOST OF THE CWA AND THE
UPPER LVL SUPPORT FROM THE H5 TROF AND A DECENT LOW LVL JET IN THE
RANGE OF 30 TO 40KTS...SHOULD PROVIDE A FAVORABLE ENVIRONMENT FOR SH
AND TS IN THE AFTERNOON/EVENING WITH SOME DEGREE OF ORGANIZATION
POSSIBLE. I ADVERTISE A SOLID CHANCE FOR SH AND TS FROM APPROX 12Z
ONWARD WITH THE HIGHEST POPS OVER THE NC MTS. SPC CURRENTLY HAS MOST
OF THE CWFA IN A SLIGHT SVR RISK THRU 12Z SAT...AND I AM THINKING
THAT THE NC MTS WILL HAVE A HIGHER OVERALL RISK COMPARED TO THE LOWER
TERRAIN ON FRI.

ON SATURDAY...THE FCST REMAINS TRICKY WITH HEIGHTS BEGINNING TO RISE
AS THE UPPER TROF PULLS AWAY TO THE NE. THE MODELS DIFFER ON THE
STRENGTH AND TIMING OF THE UPPER SHWV ENERGY ON SAT WHICH IS
EXPECTED TO BE THE MAIN TRIGGER FOR ANY CONVECTION. THE LATEST 12Z
GFS HAS A SHWV APPROACHING THE CAROLINAS BY 12Z SAT WHILE THE
ECMWF...CMC...AND NAM12 DONT HAVE THE FEATURE APPROACHING UNTIL
EARLY SUN. OVERALL...THE LOW TO MID LVL MOISTURE FLUX INCREASES
DURING THE DAY AS INSTABILITY GROWS...HOWEVER MID AND UPPER LVL
SUPPORT DWINDLES AS THE UPPER RIDGE BUILDS. HAVE SOLID CHANCE FOR
AFTERNOON/EVENING CONVECTION...WITH THE THREAT OF SIGNIFICANT
ORGANIZATION LESS LIKELY THAN FRI. TEMPS WILL REMAIN ABOUT A
CATEGORY ABOVE NORMAL WITH HIGHS AROUND 90 FOR THE LOWER ELEVATIONS
AND LOW TO MID 80S FOR THE HIGHER TERRAIN.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
AS OF 130 PM WEDNESDAY...A FAIRLY LOW AMPLITUDE UPPER PATTERN WILL
BE IN PLACE LATE THIS WEEKEND. WEAK UPPER JET MAXIMA WILL PASS
MAINLY NORTH OF THE FORECAST AREA. AT THE SFC...A FRONT WILL REMAIN
STALLED ACROSS THE REGION ON SUNDAY AND BOUNDARY LAYER MOISTURE WILL
REMAIN FAIRLY HIGH. THIS WILL WARRANT SOLID CHANCE POPS FOR
CONVECTIVE COVERAGE DURING THE AFTN AND EVENING HOURS. A DIGGING
SHORTWAVE MAY CROSS THE REGION ON MONDAY AS THE SURFACE FRONT LIFTS
SLOWLY NORTHWARD. CONVECTIVE COVERAGE SHOULD IMPROVE ON MONDAY AND
IT COULD ARRIVE IN WRN MTN LOCATIONS DURING THE MORNING...DEPENDING
ON THE SHORTWAVE TIMING.

THE WARM SECTOR AIRMASS AND ABUNDANT LOW LEVEL MOISTURE WILL THEN
REMAIN IN PLACE TUE THROUGH WED...WITH WEAK AND HARD TO TIME
SHORTWAVES LIKELY CROSSING THE REGION...OR AT LEAST THE NRN TIER OF
THE FORECAST AREA. THIS WILL LEAD TO A RETURN TO MORE DIURNALLY
FAVORED AFTN AND EVENING CONVECTION. MAX AND MIN TEMPS SHOULD REMAIN
NEAR NORMAL...OR A FEW DEGREES ABOVE NORMAL...THROUGH THE PERIOD.

&&

.AVIATION /21Z WEDNESDAY THROUGH MONDAY/...
AT KCLT...MODEL SOUNDINGS AND MESOSCALE MODEL FORECASTS INDICATE
THAT SCATTERED THUNDERSTORMS SHOULD DEVELOP DURING THE LATE
AFTERNOON HOURS VICINITY THE AIRFIELD. HENCE INCLUDED A CB INTO THE
EVENING HOURS. A WEAK FRONT AND ATTENDANT MOISTURE BAND WILL MOVE ACROSS
THE AREA THU MORNING. THEREFORE...EXPECT A LOW VFR CLOUD CEILING TO
CONTINUE. CAN'T RULE OUT A SHOWER OR THUNDERSTORM AFFECTING THE AIR FIELD
OVERNIGHT WITH THE MOISTURE INCREASE.

ELSEWHERE...SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP ACROSS
WESTERN NC AND UPSTATE SC DURING THE AFTERNOON HOURS,. HENCE ALL
AIRPORTS GET A CB MENTION. WEAK FRONT AND ATTENDANT MOISTURE BAND
WILL MOVE SLOWLY EAST ACROSS THE AREA OVERNIGHT THROUGH THU MORNING.
BEST CHANCE FOR SHOWERS/THUNDERSTORMS WITH THIS WILL BE OVER THE
MOUNTAINS...BUT ALL AIR FIELDS COULD SEE AN OVERNIGHT SHOWER OR
THUNDERSTORM. GUIDANCE SUGGESTS THAT A MVFR FOG RESTRICTION WILL
OCCUR AT KAVL LATE TONIGHT.

OUTLOOK...GENERALLY VFR CONDITIONS EXPECTED INTO THE WEEKEND EXCEPT
FOR LOCAL RESTRICTIONS IN THUNDERSTORMS EACH AFTERNOON AND
EVENING...AND IN MOUNTAIN VALLEY FOG EACH MORNING TOWARD DAYBREAK.
