Area forecast discussion, Jun 3, 2:16 PM EDT, 2 hours 50 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
216 PM EDT FRI JUN 3 2011

.SYNOPSIS...
WEAK HIGH PRESSURE WILL MOVE ACROSS THE MID ATLANTIC REGION THROUGH
SATURDAY...BEFORE A FRONTAL BOUNDARY APPROACHES FROM THE NORTH ON
SUNDAY. WARM UPPER LEVEL RIDGING WILL REMAIN OVER THE AREA THROUGH
THE MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /THROUGH SATURDAY/...
SFC BOUNDARY HAS MOVED SOUTH OF KAND...BUT MOISTURE POOLING ALONG IT
HAS HELPED TO CREATE CAPES IN THE 2000 TO 4000 J/KG RANGE OVER THE
SWRN NC MTNS AND UPPER SAVANNAH RIVER VALLEY. WATER VAPOR SHOWS THE
WAVE JUST TO OUR NORTH THAT THE GUIDANCE IS MOVING ACROSS THE AREA
THIS AFTERNOON AND EVENING. EVEN THO THERE IS A CU MINIMA ALONG AND
NORTH OF I-85 IN NE GA/UPSTATE...STILL EXPECT ENUF INSTABILITY AND
FORCING FOR SCT CONVECTION OVER THE SWRN NC MTNS AND UPPER SAVANNAH
RIVER VALLEY WITH SOME ISOLATED CONVECTION NORTH AND EAST OF THERE.
THAT SAID...SCT CONVECTION COULD BE LIMITED TO SOUTH OF I-85 WHERE
CURRENT CU GROWTH IS TAKING PLACE. SVR STORMS REMAIN LIKELY WITH ANY
STORMS THAT DO DEVELOP GIVEN THE STRONG INSTABILITY AND MID LEVEL
DRY AIR. IN FACT...EFFECTIVE BULK SHEAR NUMBERS ARE IN THE 20 KT
RANGE WHICH IS HIGHER THAN PREVIOUS DAYS AND COULD LEAD TO SOME
ORGANIZATION. CONVECTION SHOULD DIMINISH WITH LOSS OF HEATING
RESULTING IN MOSTLY CLEAR SKIES OVERNIGHT. THE NAM IS SUGGESTING LOW
STRATUS FORMS ALONG THE SRN CWFA BOUNDARY TOWARD MORNING. KEPT SKIES
THERE SCT FOR NOW. LOWS WILL BE A LITTLE BELOW NORMAL EAST IN THE
DRIER AIR MASS AND A LITTLE ABOVE WEST WHERE MOISTURE IS HIGHER.

ALTHOUGH NWLY FLOW ALOFT REMAINS OVER THE AREA SAT...THE CWFA WILL
BE IN NVA WITH NO REAL SHORT WAVE ACTIVITY MOVING TOWARD THE AREA.
LINGERING MOISTURE OVER THE MTNS WILL LEAD TO WEAK INSTABILITY...
BUT REST OF THE AREA WILL BE CAPPED WITH DRIER AIR. EVEN THOUGH
DIFFERENTIAL HEATING COULD LEAD TO ISOLATED CONVECTION OVER THE SWRN
NC MTNS...WILL KEEP THE FCST DRY FOR NOW. ALTHOUGH TEMPS WILL BE
COOLER...THEY WILL STILL END UP AROUND 10 DEGREES ABOVE NORMAL.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
AT 2 PM EDT FRIDAY...HEIGHTS WILL FALL SATURDAY NIGHT AND SUNDAY AS
THE UPPER RIDGE CENTERED OVER THE LOWER MS RIVER VALLEY RETROGRADES
TO THE SOUTHERN PLAINS. THE RIDGE CENTER THEN PROGRESSES TO RETURN
TO THE LOWER MS RIVER VALLEY ON MONDAY. OUR AREA WILL REMAIN ON THE
WARM SIDE OF SURFACE FRONT TO THE NORTHEAST SATURDAY NIGHT. THE COLD
FRONT THEN DROPS SOUTH ACROSS OUR AREA ON SUNDAY MOVING WELL INTO GA
ON MONDAY. TEMPERATURES WILL REMAIN ABOVE NORMAL BOTH SUNDAY AND
MONDAY...AS HEIGHTS ALOFT WILL STILL BE RATHER HIGH ON THE WEST SIDE
OF AN ATLANTIC UPPER TROUGH. LOW POPS WILL BE CARRIED FROM SATURDAY
NIGHT THROUGH SUNDAY NIGHT...PEAKING ON SUNDAY...AS THE BACK DOOR
COLD FRONT MOVES THROUGH AND AN UPPER LEVEL IMPULSE CROSSES CENTRAL
AND EASTERN NC. POPS DECREASE MONDAY AS THE FRONT MOVES FARTHER
SOUTH.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
AT 2 PM EDT FRIDAY...AN UPPER RIDGE AXIS WILL MOVE FROM THE PLAINS
ON TUESDAY...TO THE OH AND TN VALLEYS BY LATE IN THE WEAK...WHILE
THE RIDGE FLATTENS. ON TUESDAY A COLD FRONT WILL CLIP WESTERN
NC...BEFORE RETURNING NORTH AS A WARM FRONT ON WEDNESDAY. ON
THURSDAY AND FRIDAY OUR AREA IS IN THE WARM SECTOR...TO THE SOUTH OF
A FRONT IN THE NORTHERN TIER OF STATES. VERY SMALL POPS WILL BE
CARRIED THROUGH THE PACKAGE...AS A MOIST UNSTABLE AIR MASS WILL BE
IN PLACE...BUT WITHOUT MUCH OF A FOCUSING MECHANISM FOR HIGHER POPS.
TEMPERATURES WILL RUN SEVERAL CATEGORIES ABOVE NORMAL UNDER THE
UPPER RIDGE.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
AT KCLT...DRIER AIR MASS HAS WORKED IN BEHIND THE SWD MOVING SFC
BOUNDARY. EXPECT FEW CU AND BKN CI INTO EARLY EVENING WITH NELY
WINDS. WINDS BECOME LIGHT SE BY LATE EVENING WITH FEW CI. GUIDANCE
SHOWS LOW STRATUS DEVELOPING SOUTH OF THE AREA BY MORNING. EXPECT
THESE CLOUDS WILL MOVE TOWARD KCLT...BUT SHOULD STOP SHORT. THAT
SAID...IF THEN CAN MAKE IT FAR ENUF NORTH THEN LOW MVFR/IFR CIGS
COULD MOVE IN/DEVELOP NEAR DAYBREAK. EXPECT SLY WINDS WITH CI CLOUDS
FOR MUCH OF THE DAY SAT.

ELSEWHERE...SFC BOUNDARY IS SOUTH OF KAND...BUT MOISTURE POOLING
ALONG IT IS LEADING TO DEVELOPING CU ACROSS THE SC/NE GA. LINGERING
MOISTURE AND HEATING LEADING TO CU OVER THE MTNS. KAND HAS THE BEST
CHC OF SEEING ANY CONVECTION THIS AFTERNOON GIVEN THEIR PROXIMITY TO
THE FRONT. HAVE GONE BKN CU AND CB MENTION THERE. E TO NE WINDS WILL
CONTINUE THRU THE AFTERNOON...KAVL THE EXCEPTION WITH SLY WIND.
SKIES CLEAR AND LIGHT AND VARIABLE WINDS DEVELOP OVERNIGHT. KAVL
SHUD SEE MVFR FOG TOWARD MORNING...WITH MVFR POSSIBLE KAND. ANY
DEVELOPING LOW STRATUS SHOULD REMAIN SOUTH AND EAST OF THE SC SITES.
MOSTLY CLEAR SKIES AND SLY WIND EXPECTED SAT.

OUTLOOK...ISOLD AFTN/EVE TSTMS POSSIBLE EACH DAY...WITH EARLY
