NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before this severe thunderstorm warning went out at May 13, 5:18 PM EDT, 19 minutes earlier.

Area forecast discussion, May 13, 5:18 PM EDT, 19 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
518 PM EDT FRI MAY 13 2011

.SYNOPSIS...
LOW PRESSURE AND AN ASSOCIATED COLD FRONT WILL APPROACH THE AREA
FROM THE WEST TONIGHT...AND WILL MOVE EAST THROUGH THE AREA ON
SATURDAY. THIS LOW WILL LINGER ALONG THE CAROLINA COAST THROUGH THE
FIRST PART OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
A QUICK UPDATE FOR SVR WATCH 299 UNTIL 11 PM. AT 515 PM...MULTIPLE
COOL POOLS ARE EXPANDING ACROSS THE MTNS AND ADJACENT FOOTHILLS.
ADDITIONAL CONVECTION WILL DEVELOP ALONG THE OUTFLOW
BOUNDARIES...ESPECIALLY ACROSS THE NC FOOTHILLS AND PIEDMONT. I WILL
INCREASE POPS SIGNIFICANTLY THROUGH 3Z ACROSS THE MTNS EAST TO THE
I-77 CORRIDOR.

PREVIOUS DISCUSSION...

VIGOROUS IMPULSE RIDING UP THE BACKSIDE OF DAMPENING UPPER RIDGE
WILL CONTINUE TO AID IN LOCALLY SEVERE TSTM ORGANIZATION ACRS THE
MTNS INTO THIS EVENING. ACRS THE NC FTHLS/PIEDMONT...WHERE SFC DWPTS
SHOULD NOT CRASH...AS THEY HAVE DONE SO ACRS THE UPSTATE AND NE
GA...TSTM ACTIVITY SHOULD ALSO EXPAND IN CVRG WITHIN DEVELOPING
MODERATE INSTABILITY. PROBABLY WILL SEE A DIURNAL WEAKENING TREND
LATER THIS EVENING...BUT GIVEN FAVORABLE FLOW REGIME...SLIGHT UPPER
DIFFLUENCE...AND THE POTENTIAL FOR ADDITIONAL ENERGY TO ROTATE INTO
THE WESTERN CAROLINAS...SHOWER AND EMBEDDED TSTM ACTIVITY STANDS
THE CHANCE OF REDEVELOPMENT OVERNIGHT. ANOTHER MILD NIGHT IS
EXPECTED WITH SATURDAY MORNING MIN TEMPS ABOUT 5-7 DEG F ABV CLIMO.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/...
AS OF 225 PM FRI...A COLD FRONT WILL CROSS THE REGION SATURDAY
AFTERNOON. MODEL SOUNDINGS OFF THE GFS AND NAM SHOW AMPLE
INSTABILITY FOR SHRA AND TSTMS ALONG AND AHEAD OF THE FRONT.
HOWEVER...THERE WILL BE A COUPLE LIMITING FACTORS. A WELL DEFINED
SHORT WAVE WELL AHEAD OF THE UPPER LOW OVER MO WILL CROSS THE REGION
OVERNIGHT AND PUSH EAST OF THE FA SAT MORNING. THIS WILL KEEP THE FA
UNDER NVA UNTIL THE AFTN HOURS. EVEN AS PVA STARTS TO IMPROVE AGAIN
IN THE AFTN...A WEAKNESS IN THE MID-TROPOSPHERIC WIND FIELD WILL
PERSIST ACROSS THE FA. WINDS UP AROUND H5 WILL ONLY BE AROUND 25 TO
30 KTS. LAPSE RATES ARE NOT VERY STEEP. AS THE UPSTREAM AIRMASS HAS
BEEN OVERTURNED BY CONVECTION THE PAST FEW DAYS...THIS MAKES SENSE.
THEREFORE...WHILE I THINK THERE WILL BE GOOD COVERAGE...I DON/T
THINK THERE WILL BE MORE THAN AN ISOLATED SEVERE THREAT. I DID CUT
POPS A HAIR...BUT I/VE KEPT THEM IN THE LIKELY RANGE.

WIND SHEAR WILL INCREASE OVER THE REGION ON SUNDAY AS THE UPPER LOW
CONSOLIDATES OVER THE MID-WEST. HOWEVER...THE LLVL AIRMASS WILL BE
MUCH DRIER AND MODEL SOUNDINGS ARE GENERALLY CAPPED. SYNOPTIC SCALE
FORCING WILL INCREASE LATE IN THE DAY...AND SCT SHRA WILL BE
POSSIBLE...ESPECIALLY ACROSS THE NC MTNS WHERE NW FLOW WILL AID
ASCENT...AND OVER THE NC FOOTHILLS AND NRN PIEDMONT WILL LLVL
CONVERGENCE WILL INCREASE AHEAD OF THE LOW.

BY LATE SUNDAY NIGHT INTO MONDAY CONSIDERABLE SENSIBLE WX
DIFFERENCES DEVELOP BETWEEN THE MODELS. THE GFS QUICKLY MOVES A
STRONG UPPER WAVE ACROSS THE REGION BY MON AFTN. THE COMBINATION OF
INSTABILITY AND FORCING BRINGS QUITE A BIT OF PCPN THE
FA...ESPECIALLY THE NC ZONES...LATE MONDAY. THE EC IS MUCH SLOWER
AND DEEPER WITH THE WAVE...DROPPING IT TOWARD THE GULF. THEREFORE
IT/S DRIER ON MONDAY...BUT WETTER ABOUT 36 HOURS LATER. I COULD GO
ON AS NEARLY EVERY MODEL IS DIFFERENT. IN SHORT...FORECAST
CONFIDENCE IS QUITE LOW STARTING MONDAY AND INTO THE MIDDLE OF THE
WEEK WITH THIS PACKAGE. NOT SURPRISINGLY...THIS RESULTS IN A LOT OF
30 TO 50 PERCNET TYPE POPS FOR THIS PERIOD.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 1200 PM FRIDAY...NOT MUCH CHANGE TO THE PATTERN FROM WHAT WAS
OBSERVED BY THE MID SHIFT. A COMPLEX UPPER LOW...WITH SEVERAL
EMBEDDED SHORT WAVES...WILL BE ROUGHLY CENTERED OVER THE SRN
APPALACHIANS THROUGH WED BEFORE LIFTING TO THE NORTH IN RESPONSE TO
HEIGHT FALLS OVER THE SRN/CNTL PLAINS.

THE GFS IS FARTHER NORTH THAN THE EC AND CANADIAN WITH THE LOW
THROUGH MOST OF THE EXTENDED. THE 00 UTC RUNS OF THE LATER TWO
MODELS WERE ACTUALLY IN PRETTY GOOD AGREEMENT AS THEY TAKE ONE SHORT
WAVE WELL SOUTH OF THE AREA MON NIGHT...THEN BRING IT UP THE COAST
ON THE E SIDE OF THE UPPER LOW TUE INTO WED MORNING. THIS RESULTS IN
SFC CYCLOGENESIS OVER THE ERN CAROLINAS. IF THIS HAPPENS...PARTS OF
THE FA WOULD SEE A GOOD RAIN EVENT LATE TUE INTO EARLY WED. I HAVE
FAIRLY HIGH POPS FOR THIS PERIOD...BUT OWING TO THE RUN TO RUN
DIFFERENCES IN THE FINER SHORT WAVE FEATURES OVER THE REGION...WE/LL
NEED TO WAIT A FEW RUNS BEFORE GOING ANY HIGHER.

CONDITIONS DO LOOK TO IMPROVE LATER WED INTO FRIDAY...THOUGH SOME OF
THE FASTER MODEL SOLUTIONS BRING PCPN BACK INTO THE FA BY THE END OF
DAY 7.

&&

.AVIATION /21Z FRIDAY THROUGH WEDNESDAY/...
AT KCLT...SSW WINDS 6-8 KTS WILL BE SEEN THRU THIS AFTERNOON AND
SCT VFR LVL CU SHOULD BE OCNLY BROKEN AND PERHAPS DEVELOP INTO
CB/S DURING THE LATTER HALF OF THE AFTERNOON AND/OR EARLY EVENING
AS TSTM CHANCES INCREASE. MOISTURE WILL BE INCREASING OVERNIGHT AHEAD
OF AN APPROACHING FRONT. IT IS UNCERTAIN ON THE AMOUNT OF SHOWER
REDEVELOPMENT EARLY SATURDAY MORNING AND THERE COULD ALSO BE SOME
PRE-DAWN MVFR CLOUDS AND VSBY AROUND THE NC PIEDMONT...WHICH SHOULD
RETURN TO VFR BY LATE MORNING.

ELSEWHERE...TSTMS WILL INCREASE IN CVRG ACRS THE NC MTNS/FTLHS...AND
EVENTUALLY THE PIEDMONT INTO EARLY EVENING BEFORE DIMINISHING DURING
MID TO LATE EVENING. SCATTERED SHOWERS MAY REDEVELOP OVERNIGHT AS
WELL AS WIDESPREAD FOG. CONDITIONS TO GRADUALLY IMPROVE TO VFR AS
SATURDAY MORNING WEARS ON.

OUTLOOK...SCATTERED CEILINGS AND VISIBILITY RESTRICTIONS IN
THUNDERSTORMS MOST NUMEROUS OVER MOUNTAINS AND DURING AFTERNOONS AND
EVENINGS THROUGH END OF WEEK. MORNING MVFR FOG POSSIBLE WHERE RAIN
FELL THE NIGHT BEFORE.
