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 Oct 11, 2:53 PM EDT, 12 minutes earlier.

Area forecast discussion, Oct 11, 2:53 PM EDT, 12 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
253 PM EDT SAT OCT 11 2014

.SYNOPSIS...
A BACK DOOR COLD FRONT WILL PUSH THROUGH THE AREA TONIGHT...WITH A
COOL WEDGE OF HIGH PRESSURE BUILDING IN BEHIND THE FRONT FOR SUNDAY.
THE FRONT WILL BEGIN TO LIFT BACK NORTH AS A WARM FRONT MONDAY AHEAD
OF A STRONG COLD FRONT...WHICH WILL CROSS THE REGION TUESDAY. DRY
HIGH PRESSURE WILL THEN RETURN FOR THE LATTER HALF OF THE WEEK.

&&

.NEAR TERM /THROUGH SUNDAY/...
AT 215 PM...THUNDERSTORMS ARE INCREASING IN COVERAGE AS EXPECTED
WITH UP TO 2000J OF CAPE OVER THE PIEDMONT AND 500-1000J MOOUNTAINS.
BEGINNING TO SEE TREND FOR CONVECTION TO FAVOR THE VICINITY OF A
DEVLOPING LEE TROUGH. HOWEVER....CAMS MOVE THE CONVECTION OVER
WESTERN NC QUICKLY EASTWARD APPARENTLY WITH A AN UPPER IMPULSE. BY
00Z...THE FORECAST IS FOR MOST OF THE CONVECTION TO BE EAST OF THE
FORECAST AREA. CURRENT POP FORECAST STILL LOOKS GOOD WITH NUMEROUS
COVERAGE OVER THE NC FOOTHILLS/PIEMDONT AND JUST SCT ELSEWHERE. A
FEW STRONG TO SEVERE STORMS ARE POSSIBLE WITH 30-40KT OF SHEAR AND
MODERATE CAPE VALUES.

FOR THE OVERNIGHT...THE MODELS ARE CONSISTENT IN BACKDOORING A COLD
FRONT THROUGH THE AREA. WINDS WILL SHIFT TO TEH NE WITH CAD SCENARIO
DEVELOPING BY SUNRISE ON SUNDAY. AS ISENTROPIC LIFT DEVELOPS OVER THE
CAD...SOME LIGHT RAIN SHOWERS ARE EXPECTED TO DEVELOP OVERNIGHT AND
PERSIST ON SUNDAY...PARTICULARLY ALONG THE BLUE RIDGE AND THE
WESTERN UPSTATE COUNTIES. TEMPS WILL BEGIN TO COOL OVERNIGHT BEHIND
THE FRONT...BUT STILL REMAIN ABOVE CLIMO. ON SUNDAY WITH THE CAD...
WILL CONTINUE TO USE CONSRAW FOR TEP FIELDS WHICH KEEPS MAX TEMPS A
CATEGORY OR SO BELOW CLIMO.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH WEDNESDAY NIGHT/...
AS OF 250 PM SATURDAY...MONDAY MORNING...MID LEVEL HEIGHTS ACROSS
THE REGION WILL BEGIN TO FALL...AS A RIDGE REMAINS OVER THE WESTERN
ATLANTIC AND A DEEP TROUGH OR CLOSED LOW AMPLIFIES ACROSS THE
PLAINS. AT THE SFC...RIDGING WILL REMAIN ACROSS THE WESTERN
CAROLINAS...SOURCED FROM A MID ATLANTIC HIGH. ONGOING ISENTROPIC
LIFT AND UPSLOPE FLOW SHOULD SUPPORT NUMEROUS SHRA ACROSS THE EAST
FACING SLOPES...WITH SCT COVERAGE EAST. TEMPERATURES ARE FORECAST TO
GENERALLY RANGE IN THE MID 50S TO NEAR 60.

ON MONDAY...LINGERING AREA OF COLD AIR DAMMING SHOULD ERODE THROUGH
THE DAY...BECOMING MORE LIMITED TO THE FOOTHILL AREAS. UPSLOPE FLOW
AND WEAK ELEVATED INSTABILITY SHOULD CONTINUE TO SUPPORT SHOWERS
ACROSS THE MTNS...WITH TS EAST. OVERALL...COVERAGE OF CONVECTION IS
EXPECTED TO REMAIN IN THE CHC RANGE. HIGH TEMPERATURE PATTERN WILL
REFLECT A LINGERING WEDGE OF HIGH PRESSURE...WITH 60S ACROSS THE
UNIFOUR AND UPPER 70S ACROSS PORTIONS OF THE UPPER SAVANNAH RIVER
VALLEY.

ON TUESDAY...SHORT RANGE GUIDANCE HAS TRENDED SLOWER FROM RUNS
YESTERDAY. HOWEVER...AGREEMENT BETWEEN GUIDANCE IS FAIR WITH THE
TIMING AND PLACEMENT OF MAIN FEATURES...I WILL USE A BLEND OF THE
NAM AND GFS. BY 12Z TUESDAY...THE SFC COLD FRONT IS FORECAST TO RUN
FROM MIDDLE KY/TN SOUTH TO ALONG THE GA/AL LINE. THE NAM WIND FIELDS
INDICATE THAT A LLVL JET WILL BEGIN TO ENCOUNTER THE MTNS AROUND
12Z...WITH H85 WINDS AROUND 50 KTS THROUGH 18Z. I WILL INCREASE
RIDGETOP WINDS...FEATURING MARGINAL WIND ADVISORY GUSTS. DURING THE
DAYLIGHT HOURS...THE GFS INDICATES A CLOSED LOW OVER THE MID WEST
WITH THE TROF AXIS SWEEPING EAST ACROSS THE DEEP SOUTH. Q-VECTOR
CONVERGENCE INCREASES SHARPLY DURING THE LATE MORNING AND REMAINS
INTO THE EVENING. AT THE LLVLS...THE ENVIRONMENT ALONG AND AHEAD OF
THE COLD FRONT WILL FEATURE VERY STRONG SHEAR AND HELICITY
VALUES...WITH PIEDMONT AREAS UNDER 0-1 KM HELICITY VALUES FROM
300-400 M2/S2. INSTABILITY WILL REMAIN THE LIMITING
FACTOR...HOWEVER...NAM FORECAST SOUNDINGS INDICATE THAT PIEDMONT
AREAS COULD SEE VALUES RISE ABOVE 500 J/KG BY MID DAY. THIS FORECAST
PACKAGE DOES HAVE THE BENEFIT OF VIEWING THE SIMULATED REFLECTIVITY
FROM THE NAM. THE NAM SHOWS A WELL ORGANIZED QLCS REACHING THE NC
MTNS AROUND 15Z...GSP AREA BETWEEN 18Z-0Z...THEN CLT BETWEEN 0Z-3Z.
SHERB AND EHI VALUES BETWEEN 0-3 KM INDICATE A RIPE HIGH SHEAR LOW
CAPE ENVIRONMENT FOR WIND OR ISO TORNADOES. IN ADDITION...ABOVE
SEASONABLE VALUES OF PW AND MID TO UPPER 30S K-INDEX INDICATE THE
POTENTIAL FOR HEAVY RAIN. FLASH FLOODING WILL BE A CONCERN ACROSS
THE CWA. COVERAGE SHOULD PUSH EAST TUESDAY NIGHT...LEAVING SOME
UPSLOPE SHOWERS ACROSS THE TN/NC LINE THROUGH THE NIGHT.

&&

.LONG TERM /THURSDAY THROUGH SATURDAY/...
AS OF 200 PM SATURDAY...THERE IS STILL QUITE A BIT OF SPREAD AMONG
THE MEDIUM RANGE GUIDANCE WITH HOW THE KEEP TROF/CLOSED UPR LOW WILL
EVOLVE WED-FRI. THE ECWMF HAS BEEN CONSISTENTLY THE DEEP/SLOW
OUTLIER...WHILE THE GFS IS MORE PROGRESSIVE ALTHO TRENDING TOWARD
THE ECMWF THE LAST FEW CYCLES. I STARTED WITH THE SUPERBLEND...WHICH
TRENDS A LITTLE SLOWER ON CLEARING OUT THE WRAP-AROUND
MOISTURE/SHWRS WED INTO THU (A COMPROMISE BETWEEN THE GFS AND
ECMWF). OTHERWISE...NO SIGNIFICANT CHANGES FROM PREVIOUS FCST.

AS ALLUDED TO ABOVE...EVEN THE FASTER SOLNS WITH THE UPR LOW HAVE NW
FLOW/UPSLOPE SHWR ACTIVITY DURING THE DAY ON WED. I BUMPED UP
COVERAGE OF CHC POP IN THE NC MTNS...WITH SLGT CHC POP ALL THE WAY
TO THE FOOTHILLS. SLGT CHC POP LINGERS IN THE MTNS INTO THU.
OTHERWISE...EXPECT SLIGHTLY BELOW NORMAL TEMPS WED...THEN A GRADUAL
WARMING TREND TO SLIGHTLY ABOVE NORMAL TEMPS BY FRI/SAT. ONCE THE
UPR LOW LIFTS NE OF THE AREA...MOSTLY CLEAR SKIES AND DRY CONDITIONS
ARE EXPECTED...WITH HIGH PRES BUILDING IN UNDER FLATTENING UPR FLOW.

&&

.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
AT KCLT...IN THE NEAR TERM...THE CONCERN IS FOR THUNDERSTORMS.
INSTABILITY IS INCREASING THIS AFTERNOON AND CAMS SUGGEST THAT
THUNDERSTORMS WILL ARRIVE CIRCA 20Z. HENCE WILL ADVERTISE TEMPO TSRA
20-23Z. AFTER THAT...A BACKDOOR COLD FRONT WILL PUSH THROUGH SHIFTING
WINDS TO THE NE. A MOIST BOUNDARY LAYER WILL COOL BEHIND THE FRONT
ALLOWING FOR LOWERING CLOUDS WHICH WILL BECOME IFR TOWARD SUNRISE
WITH ONLY VERY SLOW IMPROVEMENT THROUGH SUNDAY MORNING.

ELSEWHERE...SIMILAR TO CLT IN THAT THE NEAR TERM CONCERN IS FOR
THUNDERSTORMS. INSTABILITY COPNTINUES TO INCREASE THIS AFTERNOON AND
CURRENT RADAR/CAMS SUGGEST THAT THUNDERSTORMS WILL INCREASE IN
COVERAGE BY 20Z PROBABLY FAVORING THE AREA VICINITY THE DEVELOPING
LEE TROUGH. HENCE WILL ADVERTISE TEMPO TSRA AT ALL AIRFIELDS EXCEPT
KAVL FROM 19-23Z. KAVL COULD SEE A STORM BUT CONFIDENCE NOT HIGH
ENUF EXCEPT FOR VCTS. AFTER THAT...A BACKDOOR COLD FRONT WILL PUSH
THROUGH SHIFTING WINDS TO THE NE. A MOIST BOUNDARY LAYER WILL COOL
BEHIND THE FRONT ALLOWING FOR LOWERING CLOUDS WHICH WILL BECOME IFR
MOST AREAS TOWARD SUNRISE WITH ONLY VERY SLOW IMPROVEMENT THROUGH
SUNDAY MORNING.

OUTLOOK...RESTRICTIONS WILL CONTINUE IN A MOIST AIR MASS THROUGH
MONDAY. A STRONG COLD FRONT ARRIVING TUESDAY WILL BRING A THREAT OF
VERY HEAVY RAIN AND POSSIBLY DAMAGING WIND GUSTS...FOLLOWED BY
DRYING.
