AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
207 PM EDT SAT APR 9 2011

.SYNOPSIS...
A COLD FRONT WILL APPROACH FROM THE NORTH TODAY. THE FRONT WILL MOVE
NORTHEAST AND AWAY FROM OUR AREA ON SUNDAY. ANOTHER COLD FRONT WILL
APPROACH FROM THE WEST ON MONDAY.

&&

.NEAR TERM /THROUGH SUNDAY/...
THE SEVERE THUNDERSTORM WATCH FOR THE NC MTNS AND FOOTHILLS HAS BEEN
REPLACED BY A TORNADO WATCH AS SHEAR PROFILES ARE INCREASING IN THE
WESTERLY FLOW ALOFT.

WATER VAPOR IMAGERY SHOWS THE POTENT UPSTREAM MCV OVER THE OH
VALLEY...WITH A STRONG MCC AHEAD OF IT. STRONG TO SEVERE CONVECTION
IS DEVELOPING TO THE SOUTH OF THIS FEATURE IN THE VERY UNSTABLE WARM
SECTOR AIRMASS. LAPS CAPE VALUES ARE ALREADY AROUND 3000 J/KG ACROSS
MUCH OF THE AREA...AND ADDITIONAL DEWPOINT RECOVERY IS LIKELY
THROUGH LATE AFTERNOON IN THE SOUTHERLY FLOW. FORCING IS BETTER
NORTH THAN SOUTH THROUGH THE PM HOURS...BUT HEALTHY SRN TIER POPS
WILL BE NEEDED AS OUTFLOWS DEVELOP. THERE IS CONSIDERABLE CIN TO BE
OVERCOME IN THE SOUNDINGS ACROSS SRN SECTIONS...BUT INSTABILITY WILL
BE QUITE STRONG WHEN REALIZED. FREEZING LEVELS AROUND 12 K
FT...STEEP LAPSE RATES ALOFT...AND IMPROVING SHEAR PROFILES WILL
MAKE FOR A ROBUST SEVERE WEATHER THREAT THROUGH THE EARLY EVENING
HOURS. AN ADDITIONAL WATCH MAY BE NEEDED AT SOME POINT TO THE
SOUTHEAST OF THE EXISTING WATCH. FOR NOW...STORM CORES TO 22 OR 23
KFT SHOULD BE SUFFICIENT FOR LARGE HAIL...AND VERY LARGE WILL BE
POSSIBLE ALONG WITH SIGNIFICANT WIND DAMAGE.

WARM ADVECTION WILL INCREASE ALONG THE 850 MB BAROCLINIC ZONE
THROUGH THE EVENING HOURS...WITH WARM ADVECTION THE STRONGEST IN THE
DEEPER MOISTURE ACROSS THE NE HALF. THE BEST LATER EVENING POPS WILL
BE FEATURED THERE AS THE MCV MOVES EAST OF THE AREA. PATCHY FOG IS
EXPECTED OVERNIGHT IN AREAS RECEIVING APPRECIABLE RAINFALL...AND MIN
TEMPS SHOULD BE ON THE MILD SIDE.

UPPER LEVEL HEIGHTS WILL BUILD SHARPLY OVER THE AREA THE REST OF
TONIGHT THROUGH SUNDAY. 850 MB TEMPS WILL WARM ANOTHER COUPLE OF
DEGREES UNDER THE RIDGE TO PRODUCE A VERY WARM AFTERNOON. A PLUME OF
VERY RICH THETA E AIR IS EXPECTED TO STRETCH ACROSS THE FORECAST
AREA SUN AFTN...BUT A TRIGGER FOR CONVECTION WILL BE HARD TO FIND.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
AT 2 AM EDT SATURDAY...AN UPPER TROUGH UPSTREAM WILL REACH THE
APPALACHIANS MONDAY NIGHT. ON SUNDAY OUR AREA WILL BE IN THE WARM
SECTOR BETWEEN A WARM FRONT DEPARTING THE TO THE EAST...AND A COLD
FRONT MOVING INTO THE MS RIVER VALLEY. MOIST INFLOW FROM THE GULF
AHEAD OF THE FRONT WILL BE QUITE LIMITED...AND THE BEST POPS WILL
BE RESTRICTED TO THE VICINITY OF THE FRONT AS MIT MOVES INTO OUT
AREA MONDAY AFTERNOON. THE FRONT SWEEPS ACROSS THE AREA MONDAY
EVENING...FOLLOWED BY LIMITED UPSLOPE FLOW SHOWERS IN THE NC
MOUNTAINS ALONG THE TN BORDER. SMALL CAPE AND MODERATE HELICITY
WILL ACCOMPANY THE FRONT...AND SEVERE WEATHER APPEARS POSSIBLE
AROUND FRONTAL PASSAGE. QPF WILL BE LIMITED BY THE SPEED OF THE
SYSTEM AND WEAK INFLOW AHEAD OF IT.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
AT 2 AM EDT SATURDAY...A SLOW MOVING UPPER LEVEL TROUGH WILL CROSS
THE EAST COAST ON TUESDAY...FOLLOWED BY UPPER RIDGING FROM WEDNESDAY
THROUGH FRIDAY. LATE FRIDAY AND UPPER LOW MOVES ACROSS THE SOUTH
CENTRAL PORTION OF THE NATION. A COLD FRONT WILL BE EXITING THE EAST
COAST ON TUESDAY...WITH A DRYING WESTERLY FLOW BEHIND IT. HIGH
PRESSURE MOVES ACROSS THE AREA ON WEDNESDAY AND THURSDAY...WITH
MOIST GULF INFLOW ON THE SIDE OF THE HIGH REACHING THE SOUTHERN
APPALACHIANS LATE THURSDAY. MOIST SOUTHERLY FLOW CONTINUES INTO
FRIDAY AS A COLD FRONT CROSSES THE LOWER MS RIVER VALLEY. POPS WILL
BE CARRIED WITH THE GULF MOISTURE THURSDAY AND FRIDAY. TEMPERATURES
WILL BE SEVERAL CATEGORIES ABOVE NORMAL...AS DOWNSLOPE WARMING
BEHIND THE FRONT IS FOLLOWED BY HEIGHT RISES ALOFT.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
AT KCLT...THE FIRST ROUND OF CONVECTION MOVING OFF THE BLUE RIDGE
EARLY THIS AFTERNOON IS STILL A FEW HOURS AWAY FROM THREATENING
KCLT. SHOWERS MAY FILL IN ACROSS THE PIEDMONT IN THE INTERIM...WITH
THE BEST CHANCE OF TSRA NOW LIKELY STARTING AROUND 21Z. CONVECTION
WITH THE PASSING UPPER WAVE SHOULD MOVE EAST OF THE AREA BY LATE
EVENING. LOW LEVEL NE FLOW BEHIND A WEAK FRONT SHOULD BRING MVFR
CLOUDS BACK INTO THE PICTURE OVERNIGHT. THE LOW CLOUDS WILL SCATTER
CIRCA 14Z WITH MIXING ON SUNDAY AS A RIDGE BUILDS IN ALOFT AND LOW
LEVEL FLOW BECOMES SE ONCE AGAIN.

ELSEWHERE...THUNDER CHANCES WILL BE GREATEST FROM KAVL TO KHKY
THROUGH THE AFTERNOON HOURS...WITH TSRA INCREASING AT THE SC TAF
SITES MAINLY AROUND 21Z. VFR LEVEL CB CIGS ARE EXPECTED...WITH WINDS
GENERALLY S TO SW THROUGH EVENING. A PUSH FROM THE NE IS AGAIN
EXPECTED AS A WEAK SFC BOUNDARY DIPS BACK TO THE SW...BUT ANY
ASSOCIATED MVFR CLOUDS SHOULD IMPACT MAINLY KHKY AND KAVL...AND
POSSIBLY FLIRT WITH THE UPSTATE SITES OVERNIGHT. LOW CLOUDS WILL
SCATTER UNDER THE BUILDING RIDGE SUNDAY MORNING.

OUTLOOK....STRONGER RIDGING RETURNS ON SUNDAY. SCT SHRA/TSTMS MAY
ARRIVE WITH A COLD FRONT MONDAY. DRIER HIGH PRES IS EXPECTED TUE AND
WED.
