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 18, 5:48 PM EDT, 40 minutes earlier.

Area forecast discussion, Jun 18, 5:48 PM EDT, 40 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
548 PM EDT SAT JUN 18 2011

.SYNOPSIS...
A WEAK STATIONARY FRONT WILL LINGER IN OUR AREA INTO THE WEEKEND.
THE FRONT WILL MOVE NORTH AS A WARM FRONT EARLY NEXT WEEK AS HIGH
PRESSURE MOVES INTO THE AREA.

&&

.NEAR TERM /THROUGH SUNDAY/...
RAPID FIRE UPDATES EARLY THIS EVENING TO DEAL WITH CHANGES IN WATCH
CONFIGURATIONS. IN LIGHT OF UPSTREAM CONVECTION MOVING INTO NE
GEORGIA...THOUGHT IT BEST TO LOCALLY EXTEND SVR TSTM WATCH 500 UNTIL
00Z FOR THE SAV RVR VALLEY...WHILE THE REMAINDER OF WATCH 500 HAS
BEEN CANCELLED. OTHER WATCH OVER THE LAKELANDS WILL CONTINUE. MAJOR
ALTERATIONS TO TEMP TRENDS HAVE BEEN MADE TO ACCT FOR 10-15 DEG
DROPOFF BEHIND OLD COLD POOL. MORE CHANGES COMING.

REMAINDER OF PREVIOUS DISCUSSION...
UPSTREAM MCS OVER ERN TN HAS NOT STRENGTHENED MUCH THE PAST COUPLE
HOURS...THOUGH CORE HEIGHTS ALONG THE LINE ARE FINALLY STARTING TO
REACH OBJECTIVE SEVERE CRITERIA. KMRX IS SHOWING A WELL ESTABLISHED
AND STRONG COLD POOL/REAR INFLOW JET BEHIND THE LINE...AND IT SHOULD
STRENGTHEN RAPIDLY AS IT MOVES INTO THE MORE UNSTABLE AIR OVER THE
GREAT VALLEY. AS THE STRONG COLD POOL MOVES INTO THE
MOUNTAINS...WHICH ARE QUITE MIXED AT THIS POINT...POCKETS OF
DAMAGING WINDS ARE EXPECTED TO DEVELOP. AS THE LINE MOVES EAST OF
THE MTNS...INTO AN ENVIRONMENT OF HIGHER DAPE...THE MCS SHOULD BEGIN
TO SURGE EASTWARD. THE 12 UTC NAM NOW HAS BULK SHEAR VALUES OF
AROUND 40 KTS OVER THE ENTIRE FA THROUGH THE AFTN HOURS...WHICH ALSO
BODES WELL FOR THE EVOLUTION OF THE LINE AS IT PROGRESSES INTO AN
INCREASINGLY UNSTABLE AIRMASS.  THE 15 UTC RUN OF THE WORKSTATION
WRF-ARW SHOWS AN EVEN MORE HIGHLY EVOLVED BOW ECHO MOVING ACROSS THE
FA DURING THE EARLY TO MID AFTN HOURS THAN IT DID BEFORE...AND STILL
LINES UP FAIRLY WELL WITH THE MCS OVER ERN TN. THEREFORE...THIS
SHOULD SOON TRANSITION INTO A SIGNIFICANT DAMAGING WIND EVENT FOR
THE FA.

OVERNIGHT AND INTO SUNDAY MORNING...THE NAM DEVELOPS A 30-40KT LLVL
JET OVER THE FA AS HEIGHTS RISE TO OUR WEST. THIS POOLS BL DEWPOINTS
OVER 70S DEGREES ACROSS THE CENTRAL PART OF THE FA. THIS SHOULD
SUPPORT NOCTURNAL ELEVATED CONVECTION OVERNIGHT...THOUGH I/M UNSURE
HOW STRONG ON HOW WIDESPREAD IT WILL BE.

ADDITIONAL CONVECTIVELY INDUCED MCV/S WILL CROSS THE FA ON SUNDAY.
THE NAM IMPLIES A GOOD THREAT OF ADDITIONAL SEVERE STORMS WHILE THE
GFS IS FARTHER NORTH. CONSIDERING THE ONGOING CONVECTION AND HOW
SOUTH IT SHOULD MOVE OVERNIGHT...THE TREAT WILL PROBABLY BE ORIENTED
FARTHER SOUTH THAN THE GFS IMPLIES ON SUNDAY...ONCE AGAIN PUTTING US
UNDER THE GUN.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
AS OF 1245 PM SATURDAY...UPPER HEIGHTS OVER THE CWFA WILL START
THEIR RISE ON MONDAY AS GULF COAST RIDGING POKES NORTH AND EAST.
WITH SOLID LOWER TO MID 90S FCST ACRS JUST ABOUT ALL THE MAJOR
VALLEYS AND INTO THE PIEDMONT...THE ATMOSPHERE WILL LIKELY BECOME
MODERATELY UNSTABLE. THERE DOES NOT LOOK TO BE MUCH TO INHIBIT
AFTERNOON AND EVENING TSTM DEVELOPMENT...IN FACT...ENOUGH MID LVL NW
FLOW EXISTS TO GIVE RISE TO A FEW SVR STORMS.

SHORT RANGE MODELS REMAIN CONSISTENT IN DEPICTING BLDG UPPER RIDGE
ATOP THE CWFA ON TUESDAY. THE RESULTANT VERY WEAK FLOW AND WEAKLY
FORCED ENVIRONMENT SHOULD LIMIT DIURNAL DEEP CONVECTION...ESPECIALLY
AWAY FROM THE HIGHER TERRAIN...WHERE THE FCST SNDGS LOOK TO REMAIN
CAPPED. OTHERWISE...THE HEAT WAVE WILL CONTINUE AND THE GOING SWATH
OF MID TO UPPER 90S MAX TEMPS LOOK GOOD.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
AS OF 1215 PM SATURDAY...THE TREND TOWARD LESS HOT CONDITIONS
COMMENCES ON WEDNESDAY AS UPPER RIDGE AXIS ATOP THE SE CONUS
TRANSLATES EASTWARD. AS HEIGHTS START TO FALL AND RETURN FLOW
MOISTURE BEGINS AN UPWARD CREEP...WOULD EXPECT TSTM CHANCES TO CLIMB
BACK TO NEAR CLIMO PROBABILITIES.

CENTRAL CONUS TROUGH LOOKS TO CONTINUE TO IMPINGE UPON THE EASTERN
SEABOARD ON THURSDAY...AND GIVEN THE PROBABILITY OF INCREASED LARGER
SCALE FORCING...POP WILL BE INCREASED TO SOLID CHANCE AND EXPANDED
ACRS THE WHOLE CWFA. MEDIUM RANGE MODELS ARE STILL ADVERTISING L/WV
TROUGH AXIS TO SET UP ATOP THE EASTERN CONUS ON FRIDAY BEFORE
LIFTING SOME NEXT SATURDAY. AN ATTENDANT FRONTAL ZONE SHOULD SAG
SOUTH INTO THE REGION AS WELL BUT THE SOUTHWARD PENETRATION AND ANY
INFLUX OF DRIER AIR BY THE END OF THE PERIOD IS QUESTIONABLE AND
PROBABLY DOUBTFUL. GIVEN THIS...WILL MAINTAIN TOKEN CHANCE POP FOR
DAYS 6-7 ALONG WITH MAX TEMPERATURES NEAR EARLY SUMMER NORMALS.

&&

.AVIATION /22Z SATURDAY THROUGH THURSDAY/...
KCLT...BIG NEWS OF THE DAY IS THE MCS THAT IS NOW PUSHING INTO THE
MOUNTAINS. WITH THE UNSTABLE AIRMASS EAST OF THE MTNS...IT SHOULD
RAPIDLY MOVE EASTWARD OVER THE NEXT FEW HOURS. THE MOST LIKELY TIME
FOR STORM PASSAGE IS AROUND 21 UTC. I/M GIVING A 3 HOUR WINDOW OWING
TO DEVELOPMENT AHEAD OF THE LINE AND A LINGERING PERIOD OF THUNDER
AND HEAVY RAIN BEHIND IT. WINDS WILL GUST OUT OF THE WEST AS THE
LINE CROSSES...AND WILL BE WSW AHEAD OF IT...AND ERRATIC AND
VARIABLE OVERNIGHT BEHIND. A LITTLE FOG IS POSSIBLE LATE TONIGHT
DEPENDING HOW MUCH RAIN FALLS...BUT WITH HIGH CLOUDS LIKELY LASTING
THROUGH THE NIGHT...NOT EXPECTING MORE. ALSO...SCT SHRA/TSTMS MAY
DEVELOP AGAIN LATE TONIGHT AND SUN MORNING...THOUGH I HAVE NOT
INCLUDED THAT IN THE TAF YET.

ELSEWHERE...THINKING FOR THE OTHER TAF SITES IS BASICALLY THE SAME
AS FOR CLT WITH A WIDESPREAD LINE OF STRONG TO SEVERE STORMS
EXPECTED TO CROSS THE REGION FROM THE WEST THIS AFTN. BEHIND THE
LINE...AREAS OF FOG WILL BE POSSIBLE LATE TONIGHT. HOWEVER...HIGH
CLOUDS SHOULD INHIBIT WIDESPREAD FOG. IN FACT...SHRA AND TSTMS MAY
DEVELOP AGAIN OVER THE REGION LATE TONIGHT.

OUTLOOK...THERE WILL BE A GOOD CHANCE OF THUNDERSTORMS AGAIN ON
SUNDAY. DRIER AND HOT WEATHER IS EXPECTED MONDAY AND
TUESDAY...THOUGH ISOLATED TSTMS ARE POSSIBLE IN THE MTNS. A COLD
FRONT WILL BRING A BETTER CHANCE OF TSTMS...AND RESTRICTIONS...BY
WED OR THU.
