AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
508 PM EDT SUN JUN 5 2011

.SYNOPSIS...
A STORM SYSTEM WILL APPROACH THE NORTH CAROLINA MOUNTAINS FROM THE
WEST TONIGHT. WARM UPPER LEVEL RIDGING WILL STRENGTHEN FROM THE
LOWER MISSISSIPPI VALLEY INTO MID WEEK. A WEAK COLD FRONT WILL
APPROACH FROM THE NORTH NEXT WEEKEND.

&&

.NEAR TERM /THROUGH MONDAY/...
AS OF 2100 UTC...CONVECTION HAS REALLY TAKEN OFF ACRS OUR NC ZONES.
STILL NOT ORGANIZED...BUT MOST CELLS ARE REACHING SEVERE CRITERIA
FOR DOWNBURSTS AND LARGE HAIL. MEANWHILE...MCS OVER ERN TN HAS
TRENDED MORE OF A SWD MOVEMENT. MAIN AREA OF FOCUS SEEMS TO BE FROM
NRN NC BLUE RIDGE TO SW OF CLT ON A SUBTLE BNDRY. HAVE UPDATED THE
POPS/WX TO REFLECT TRENDS...BUT ANOTHER UPDATE MAY BE NEEDED WITHIN
NEXT COUPLE HOURS DUE TO QUICK EVOLUTION OF COVERAGE/INTENSITY.
OTHERWISE...ALL OTHER CHANGES TO FCST WERE MINOR.

CONVECTIVE TRENDS STILL UNCERTAIN EVEN AT THIS HOUR. GUIDANCE STILL
SUGGESTING A WAVE DROPS ACROSS OUR CWFA IN THE NLY FLOW PROVIDING
SCT COVERAGE NORTH AND EAST...AND ISOLATED AT BEST SW. HOWEVER...
MCS NEAR THE KY/TN BORDER HAS TAKEN A SOUTHWARD TURN. THE MCS COULD
TAKE A SOUTH OR SE TRACK. A SE TRACK WOULD BRING ORGANIZED
CONVECTION OVER THE WRN CWFA WHILE A S TRACK WOULD TAKE IT TO OUR
WEST. TAKING A LOOK AT CURRENT SYSTEM MOVEMENT...CORFIDI VECTORS AND
MEAN H85-H3 WIND...SHOWS THE WRN CWFA MAY BE UNDER THE GUN FROM THIS
SYSTEM. THEREFORE...WILL ADD SCT POP TO THE WESTERN CWFA. LATER
SHIFT HAS A COUPLE OF HOURS TO REFINE THE FCST AND GO WITH HIGHER
POP SHOULD THE SITUATION WARRANT. SEVERE STORMS ARE LIKELY...
ESPECIALLY IF THE MCS MOVES IN TO HELP ORGANIZE THE STORMS.
ATMOSPHERE IS VERY UNSTABLE WITH DCAPE OVER 1000 J/KG AND EFFECTIVE
SHEAR IN THE 20 TO 40 KT RANGE. THE CONVECTION MAY LINGER THRU THE
EVENING AND FINALLY DISSIPATE/MOVE OUT NEAR MIDNIGHT. EXPECT QUITE A
BIT OF DEBRIS CLOUD MUCH OF THE NITE...WITH LOWS AGAIN ABOVE NORMAL.

GUIDANCE SUGGESTS THE ATMOS BECOMES UNSTABLE ONCE AGAIN MONDAY
AFTERNOON AS LOW LEVEL MOISTURE LINGERS ACROSS THE AREA. WITH COOLER
TEMPS IN PLACE...ATMOS APPEARS TO BE CAPPED ACROSS THE NRN CWFA.
HOWEVER...THERE COULD BE SOME WEAK UPSLOPE FLOW AND DIFFERENTIAL
HEATING TO PRODUCE ISOLATED TSRA OVER THE NE GA...UPSTATE AND THE
WRN MTNS. HAVE INCLUDED SLIGHT CHC POP FOR THESE AREAS. HIGHS WILL
BE COOLER...BUT STILL ABOVE NORMAL.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
AS OF 155 PM SUNDAY...UPPER LEVEL RIDGING REASSERTS ITSELF ACROSS
THE SE CONUS DURING THE SHORT RANGE. MODELS AGREE WELL WITH
MAINTAINING A CLOSED 588 DM HIGH ACROSS MIDDLE TN SHIFTING SLOWLY
EAST TO THE TN/NC BORDER BEGINNING MID DAY TUE THROUGH WED NIGHT.
THERE IS TOO MUCH DIFFERENCE IN THE OP MODELS WRT TO A SE/WARD
DIVING S/W ON THE FRONT END OF THE ANTICYCLONE TO WARRANT MUCH
CONCERN....BUT SOME ENHANCEMENT OF DIURNAL MOUNTAIN CONVEC IS
CERTAINLY POSSIBLE LATER TUE WITH COLD POOL ORGANIZATION PUSHING
TSTMS INTO THE PIEDMONT INTO THE LATE EVENING. SOUNDINGS REMAIN
RATHER BENIGN OUTSIDE THE NC MTNS WITH THE MLVLS REMAINING TOO
WARM...HOWEVER HIGH AMOUNTS OF ELCAPE COULD BE REALIZED IF AN
ORGANIZED MCS GETS GOING ACROSS THE NC MTNS. POPS HAVE BEEN KEPT IN
THE ISOL RANGE FOR TUE EVENING...BUT THIS COULD BE SITUATION TO
WATCH FOR STRONG TO SEVERE POTENTIAL. ON WED...THE UPPER HIGH AND
STRONG NVA WILL HAVE MORE INFLUENCE OVER THE CWFA AND IT WILL BE
LESS LIKELY FOR ANYTHING BUT DIFFERENTIAL HEATING OR MOUNTAIN TOP
CONVECTION FIRING UP. POPS WERE MAINTAINED RIGHT AROUND CLIMO
FOR WED AFTERNOON. MAX TEMPS AGAIN WILL REACH WELL ABOVE
NORMAL...ABOUT 10 ABOVE FOR TUE AND EVEN A COUPLE MORE DEGREES
HOTTER ON WED. MINS WILL AVERAGE ABOUT 10-12 DEGREES ABOVE
NORMAL.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
AT 2 PM EDT SUNDAY...AN UPPER RIDGE WILL EXIST OVER THE EASTERN TWO
THIRDS OF THE NATION FROM THURSDAY THROUGH SUNDAY. THIS RIDGE WILL
FLATTEN OVER THE WEEKEND. SURFACE HIGH PRESSURE WILL REMAIN OVER OUR
AREA. A COLD FRONT SETTLES INTO THE POTOMAC RIVER VALLEY BY SUNDAY.
TEMPERATURES WILL BE ABOVE NORMAL...WITH A SLIGHT DECREASE AS
HEIGHTS FALL ALOFT OVER THE WEEKEND. SMALL POPS WILL BE CARRIED
THROUGH THE PERIOD...WITH THE GREATEST COVERAGE DURING DAYTIME
HEATING.

&&

.AVIATION /21Z SUNDAY THROUGH FRIDAY/...
AT KCLT AND ELSEWHERE...CONVECTIVE TRENDS STILL UNCERTAIN ATTM. MCS
NEAR KY/TN BORDER TAKING A SRN JOG AND MAY MISS THE CWFA ENTIRELY.
STILL EXPECTING SOME WAVE TO DIVE INTO THE AREA AND PROVIDE FOCUS
FOR CONVECTION. ATMOS ALREADY VERY UNSTABLE...SO ANY FORCING SHOULD
SET OFF ORGANIZED CONVECTION. THE NC SITES STILL THE MOST LIKELY
LOCATION TO SEE ANY TSRA...SO HAVE KEPT CB THERE. LESS CHC OVER SC
SO NO CB. HAVE ADJUSTED TIMING SLIGHTLY TO LATEST THINKING. N TO NW
WIND OVER NC WITH W TO NW OVER SC THIS AFTERNOON...BECOMES LIGHT NLY
TO NELY THIS EVENING. CONVECTION COULD LINGER THRU MIDNIGHT OR SO...
THEN MAINLY HIGH VFR CIGS EXPECTED. MTN VALLEY FOG EXPECTED ONCE
AGAIN. LIGHT NE WIND WITH DEVELOPING CU EXPECTED THRU THE MORNING
MONDAY.

OUTLOOK...A RETURN TO AN ISOLATED DIURNAL TSTM THREAT MON AFT THRU
THU WITH RIDGING ALOFT. MTN VALLEY FOG POSSIBLE EACH MORNING.

&&
