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 Mar 23, 5:26 PM EDT, 5 minutes earlier.

Area forecast discussion, Mar 23, 5:26 PM EDT, 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
526 PM EDT FRI MAR 23 2012

.SYNOPSIS...
A WARM AND MOIST AIR MASS WILL LINGER ACROSS THE REGION TONIGHT
AHEAD OF A COLD FRONT. THE FRONT WILL CROSS THE CAROLINAS AND
NORTHEAST GEORGIA ON SATURDAY...FOLLOWED BY AN UPPER LEVEL LOW ON
SUNDAY. DRY HIGH PRESSURE WILL BUILD ACROSS THE REGION SUNDAY NIGHT
AND WILL REMAIN THROUGH WEDNESDAY.

&&

.NEAR TERM /THROUGH SATURDAY/...
AS OF 5 PM EDT...UPDATED THE FORECAST TO INCREASE POPS AHEAD OF THE
DEVELOPING MCS OVER THE UPSTATE AND WRN NC FOOTHILLS...AND DECREASE
POPS BEHIND IT. ADDITIONAL CONVECTION WILL PROBABLY MOVE BACK INTO
NE GA AND THE WRN UPSTATE IN A CPL HOURS...BUT POPS WILL BE KEPT LOW
UNTIL THE STORMS START TO SHOW SOME ORGANIZATION.

PREVIOUS DISCUSSION...
UPPER LOW AND ASSOC SHORTWAVE TROFS CONTINUE MOVG E TOWARD THE
REGION WHILE MOIST S LL FLOW INCREASES OVER THE AREA. SHWRS AND
TSTMS WILL CONTINUE TO DEVELOP AND MOVE NE ACROSS THE CWA THIS
EVE...TAPERING OFF SOMEWHAT OVERNIGHT...THEN REDEVELOPING SAT AS THE
UPPER LOW TRACKS E ACROSS THE CWA ON THE WAY TO THE CAROLINA COAST.
FCST SOUNDINGS SHOW SOME CAPE AND SHEAR THRU THIS EVE BUT SVR THREAT
IS SOMEWHAT LIMITED DUE TO MOIST PROFILES AND WEAK SHEAR. AS THE
UPPER LOW MOVES IN SAT SHEAR/CAPE INCREASE...AND WITH A LITTLE DRY
AIR IN THE MID LVLS THERE WILL BE A HIGHER THREAT OF DAMAGING
WIND/HAIL...MAINLY SAT AFTN-EVE. SPC HAS THE SE CWA IN AN AREA FOR
SLIGHT RISK OF SVR STORMS AND THIS LOOKS REASONABLE. TEMPS WILL
REMAIN ABOVE AVG THRU SAT.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
AS OF 2 PM FRIDAY...ANY CONVECTION THAT DEVELOPS ALONG LEE TROF/COLD
FRONT ACRS THE FTHLS/PIEDMONT SAT AFTN SHUD BE PUSHING EAST OF THE
AREA SAT EVE. THERE MAY BE A LULL IN PRECIP COVERAGE BEHIND THAT
BATCH OF CONVECTION OVERNIGHT BEFORE THE CENTER OF AN UPPER LOW
CROSSES THE AREA EARLY SUN MRNG. AS THE LOW PASSES...ANOTHER ROUND
OF SCATTERED SHWRS SHUD CROSS THE AREA. INSTBY WILL BE ELEV AND
WEAK. SO LTL IN WAY OF THUNDER CHCS EXPECTED. MIN TEMPS STILL ABOVE
NORMAL IN THE 40S MTNS AND LWR-MID 50S PIEDMONT.

SUNDAY...HEIGHT RISES IN WAKE OF UPPER LOW AND STRENGTHENING NWLY
LLVL SHUD PUT END TO PRECIP...SAVE FOR TN BORDER WHERE UPSLOPE WILL
CONTINUE. TEMPS STILL EXPECTED TO BE ABOVE NORMAL AS THICKNESSES
QUICKLY REBOUND BEHIND THE LOW AND ALSO DOWNSLOPE EAST OF THE MTNS
(HIGHS IN THE 60S MTNS AND LWR-MID 70S PIEDMONT).

SUNDAY NIGHT AND MONDAY...AN UPPER LEVEL RIDGE WILL AMPLIFY ACRS THE
CENTER OF THE CONUS...WHILE A TROF DIGS OVER THE NORTHEAST STATES.
THIS AMPLIFYING FLOW WILL ALLOW A STRONG CP AIR MASS TO PUSH INTO
THE EASTERN GREAT LAKES TO THE MID ATLANTIC WITH THE COLD FRONT
APPROACHING THE CWFA FROM THE NORTH. BOTH THE NAM AND GFS HAVE 850
MB TEMPS STILL IN THE 10-12C RANGE WITH DOWNSLOPE NNWLY FLOW. THE
BACKDOOR FRONT MAY PUSH IN MON AFTN...BUT FOR NOW EXPECTING IT TO
REMAIN NORTH OF THE AREA. SO I AM FORECASTING HIGHS IN THE MID-UPR
70S EAST OF THE MTNS (EXCEPT LWR 70S MTN VALLEYS AND 60S HIGH
TERRAIN).

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 230 PM FRIDAY...THE LATEST EXTENDED MODELS ARE IN GOOD
AGREEMENT WITH STRONG CANADIAN SURFACE HIGH PRESSURE OVER THE GREAT
LAKES PUSHING INTO OUR FORECAST AREA MONDAY AND LINGER INTO
WEDNESDAY. AS A RESULT...MOSTLY DRY CONDITIONS WITH COOLER
TEMPERATURES CAN BE EXPECTED ACROSS THE REGION THROUGH WEDNESDAY. A
WEAK COLD FRONT IS PROGGED TO CROSS THE CAROLINAS AND NE GEORGIA
WEDNESDAY NIGHT INTO THURSDAY MORNING. BOTH THE GFS AND THE ECMWF
INDICATE THAT THE LOWER PIEDMONT AREA WILL STAY MOSTLY DRY AS THE
UPPER LEVEL DYNAMICS WEAKENS AND THE AIRMASS REMAINS RELATIVELY DRY.
HOWEVER..DECENT LLVL NW FLOW LIFTING ALONG WITH WEAK DIURNAL
INSTABILITY OVER THE NC MOUNTAINS MAY SUPPORT FOR THE DEVELOPMENT OF
SCATTERED SHOWERS AND THUNDERSTORMS DURING THE PASSAGE OF THE FRONT.
HENCE...I MENTIONED 20-30 POPS THERE WITH MOSTLY DRY CONDITIONS
ELSEWHERE. FRIDAY AND SATURDAY...ANOTHER CANADIAN HIGH PRESSURE OVER
THE GREAT LAKES AND SE CANADA IS EXPECTED TO PUSH SOUTH ACROSS THE
REGION FOR MOSTLY DRY WEATHER AND MILD CONDITIONS THROUGH THE
PERIOD.

&&

.AVIATION /22Z FRIDAY THROUGH WEDNESDAY/...
AT KCLT...MAIN CONCERN WILL BE CONVECTION DEVELOPING/MOVG IN LATER
THIS AFTN WITH A CHC OF TSTMS BY 20Z. RESTRICTIONS SHOULD BE LIMITED
TO HEAVIER SHWRS THAT MAY DEVELOP AND MOVE OVER THE FIELD. EXPECT
MVFR CIGS LATER THIS EVE TO LOWER TO IFR AFT 08Z. FOG WILL LIKELY BE
A PROBLEM FOR AT LEAST A COUPLE HOURS AROUND DAYBREAK. CHC OF TSTMS
AGAIN SAT...ESP AFTN.

ELSEWHERE...SIMILAR TO KCLT WITH EARLIER TIMING ON ONSET OF
CONVECTION. EXPECT LIFR/VLIFR AROUND DAYBREAK AT KAVL.

OUTLOOK...SCATTERED TSTMS SHOULD CONTINUE SAT EVE AND SUN AS AN
UPPER LOW CENTER MOVES SLOWLY ACROSS THE REGION. EXPECT IFR
RESTRICTIONS SUN MRNG AND WITH HEAVIER SHWRS AND TSTMS. DRYING IS
EXPECTED EARLY NEXT WEEK.
