AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
147 PM EDT THU JUN 2 2011

.SYNOPSIS...
AS A VERY WEAK COOL FRONT APPROACHES FROM THE NORTH...EXPECT DAILY
THUNDERSTORM CHANCES AND LOWERING TEMPERATURES TODAY AND FRIDAY.
UPPER RIDGING WILL STRENGTHEN AGAIN THIS WEEKEND...ALLOWING
TEMPERATURES TO WARM AGAIN INTO EARLY NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 1030 AM EDT...NAM 1000-850 MB THICKNESSES ARE ABOUT 8 METERS
LOWER OVER THE NRN ZONES TDA THAN THEY WERE ON WED...AND OVER THE
SRN ZONES...INCREASING CLOUDS SHOULD OVERSPREAD THE AREA IN THE
AFTN. THEREFORE...TEMPS SHOULD BE A FEW DEGREES COOLER TODAY THAN ON
WED ACROSS MOST OF THE REGION. THAT SAID...MAX TEMPS WILL STILL BE
WELL ABOVE NORMAL AGAIN TODAY. 12Z OBSERVED THICKNESS VALUES SUPPORT
THIS. 12Z GSO RAOB SHOWS STEEP MID LEVEL LAPSE RATES REMAIN.
HOWEVER...RAOB IS NEARLY STABLE WITH THE DRIER AIR MOVING IN. THIS
SHOULD TRANSLATE TO MOST OF THE NC FOOTHILLS...PIEDMONT AND NRN
MTNS. POPS WILL BE KEPT IN THE SINGLE DIGITS THERE.

WHILE THE NRN ZONES WILL DRY OUT...A WEAK BNDRY WILL POOL MOISTURE
OVER NE GA...THE WRN UPSTATE AND THE SRN NC MTNS. 12Z FFC RAOB IS
STILL VERY UNSTABLE WITH LESS CONVECTIVE INHIBITION IN THE LOWEST
10KFT OF THE ATMOSPHERE THAN OVER THE PAST FEW DAYS. FCST SOUNDINGS
SUPPORT THIS CONTINUING THRU THE DAY. SHEAR REMAINS WEAK...BUT
OUR WORKSTATION MODELS ARE SHOWING CONVECTIVE DEVELOPMENT IN THESE
AREAS FOR THE FIRST TIME SINCE THE STRONG RIDGE MOVED IN. THEREFORE
HAVE CONTINUED THE HIGH CHANCE TO LOW LIKELY POPS ACROSS THE
NC/SC/NC BORDER...WHICH HIGHER POPS ALSO EXTENDING SOUTHWARD ALONG
THE SAVANNAH RIVER AND OVER THE WRN UPSTATE. SPC HAS TRIMMED THE
SLIGHT RISK ARE A LITTLE. HOWEVER...STORMS THAT FORM THIS AFTN WILL
PRODUCE MICROBURSTS AS DELTA THETA-E VALUES ARE AROUND 30 DEGREES
AND DCAPES ARE OVER 1000 J/KG. FREEZING LEVELS ARE UP AROUND
14KFT...SO MOST OF THE HAIL SHOULD BE SMALL.

ONCE CONVECTION ENDS THIS EVENING IT WILL BE A FAIR NIGHT WITH AREAS
OF FOG OVER THE MTNS AND WHERE HEAVIER RAIN FALLS DURING THE DAY.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
AS OF 205 AM THURSDAY...WEAK EASTERLY LLVL FLOW WILL AID IN DIURNAL
TSTM ACTIVITY ON FRIDAY...LIMITED TO THE WESTERN AND SOUTHERN CWFA
WERE TERRAIN LIFT...MOISTURE AND INSTABILITY WILL BE GREATEST. A
GOOD CHUNK OF THE NC PIEDMONT LOOKS TO BE CAPPED WITHIN THE LINGERING
DRY AIR. ALTHOUGH THE TREND TOWARD LESS HOT CONDS WILL CONTINUE...MAX
TEMPS WILL STILL AVERAGE BETWEEN 5 AND 10 DEG F ABV CLIMO. DESPITE
POCKETS OF MODERATE INSTABILITY FCST TO DEVELOP SATURDAY
AFTERNOON...FORCING FOR DEEP CONVECTION LOOKS TO BE VERY WEAK. FCST
SNDGS ARE NOT DEFINITIVELY CAPPED...BUT OPERATIONAL AND ENSEMBLE
MODEL RESPONSE IS VERY LIMITED. BASED ON THIS...WILL FEATURE JUST A
SLIGHT CHANCE FOR AFTERNOON TSTMS ACRS THE MTNS. WITH THE LLVL FLOW
ASSUMING A WEAK WESTERLY TENDENCY...MAX TEMPS SHOULD BE A COUPLE OF
DEGREES WARMER THAN FRIDAY.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
AT 1 PM EDT THURSDAY...THE MODELS ARE IN BASIC AGREEMENT ON AN UPPER
RIDGE AXIS MOVING FROM THE PLAINS ON MONDAY...TO THE EASTERN THIRD
OF THE NATION BY THURSDAY. A BACK DOOR COLD FRONT WILL BE LOCATED TO
OUR SOUTH ON MONDAY...WITH HIGH PRESSURE TO THE NORTH. THIS FRONT
WEAKENS AND MOVES FARTHER SOUTH BY TUESDAY. WEDNESDAY AND THURSDAY
FEATURE HIGH PRESSURE CENTERED TO OUR SOUTH...WITH OUR AREA IN THE
WARM SECTOR TO THE SOUTH OF A FRONT IN THE NORTHEAST. SMALL POPS
WILL BE MAINLY CONFINED TO SAVANNAH RIVER VALLEY MONDAY AND
TUESDAY...CLOSEST OT THE DEPARTING FRONT...MIGRATING TO THE
MOUNTAINS WEDNESDAY AND THURSDAY...WHERE DIFFERENTIAL HEATING AND
OROGRAPHIC EFFECTS WILL COME INTO PLAY. TEMPERATURES WILL
RUNS SEVERAL CATEGORIES ABOVE NORMAL UNDER THE UPPER RIDGE...EVEN
BEHIND THE COLD FRONT ON MONDAY AND TUESDAY.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
AT KCLT...EXPECT NLY WIND WITH SCT CU AND BKN CI INTO EARLY EVENING.
WIND BECOMES LIGHT NE BEFORE MIDNIGHT WITH SOME LINGERING CU AND BKN
CI. NELY WIND INCREASES IN SPEED TOWARD DAYBREAK AS DRIER AIRMASS
MOVES IN FROM THE NE. COULD EVEN BE SOME LOW END GUSTS AS MIXING
BEGINS. WITH THE WIND AND DRIER AIRMASS...DO NOT EXPECT A REPEAT OF
MORNING BR/HZ. BKN CIRRUS WILL CONTINUE WITH POSSIBLY SOME MID CLOUD
CIGS AS WELL.

ELSEWHERE...NLY WIND CONTINUES THRU THE AFTERNOON FOR THE NC
SITES...BUT S TO SW WIND DEVELOPS FOR THE SC SITES. GOOD CHANCE OF
TSTMS STILL EXPECTED ALONG AND WEST OF A KAVL TO KGSP LINE THIS
AFTERNOON AND EARLY EVENING. HAVE KEPT CB MENTION IN THOSE AREAS.
KHKY SHUD REMAIN DRY. TEMPO LOW VFR CIGS POSSIBLE...BUT LEFT OUT OF
TAF FOR NOW. EXPECT LIGHT WIND OVERNIGHT WITH CONVECTION DIMINISHING
FROM NORTH TO SOUTH. N TO NE WIND PICKS UP AGAIN NEAR DAYBREAK.
DRIER AIR MASS SHOULD REACH KHKY...BUT WILL LIKELY REMAIN EAST OF
THE OTHER STIES. THAT SAID...RESTRICTIONS WILL BE MOST LIKELY AT
KAVL SO HAVE INCLUDED MVFR THERE. WILL LEAVE OTHERS MVFR...BUT
CANNOT RULE OUT SOME MVFR THO WINDS WILL BE A LITTLE STRONGER.
