Severe Thunderstorm Warning 311, NWS Greenville-Spartanburg, SC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
750 PM EDT THU AUG 22 2013

.SYNOPSIS...
WEAK HIGH PRESSURE WILL LINGER OVER THE AREA INTO EARLY FRIDAY WHEN
A COLD FRONT BEGINS TO MOVE INTO THE AREA. THE COLD FRONT IS
EXPECTED TO CROSS THE REGION FRIDAY NIGHT INTO SATURDAY...USHERING
IN DRIER WEATHER FOR THE WEEKEND. HIGH PRESSURE THEN BUILDS BACK IN
FOR THE FIRST PART OF THE WEEK...BEGINNING A GRADUAL WARMING TREND.

&&

.NEAR TERM /THROUGH FRIDAY/...
AS OF 750 PM...CONVECTION RAPIDLY DIMINISHING OVER THE AREA THIS
EVENING. HOWEVER...LINGERING CONVECTION COULD CONTINUE OVER THE I-77
CORRIDOR FOR A FEW MORE HOURS AS A WEAK WAVE DROPS ACROSS THE AREA.
OTHERWISE...EXPECT A DRY OVERNIGHT WITH FOG DEVELOPING AND BECOMING
PATCHY DENSE ACROSS THE MTN VALLEYS. LOWS SHUD BE NEAR TO SLIGHTLY
ABOVE NORMAL.

AS OF 430 PM...CONVECTION REMAINS CONCENTRATED SOUTH OF I-85 OVER NE
GA AND THE WRN UPSTATE. WITH SCT CONVECTION BACK ACROSS THE NC MTNS
AND SRN FOOTHILLS. EXPECT BEST COVERAGE TO REMAIN OVER THIS ARE THRU
THE LATE AFTERNOON. HOWEVER...THERE IS SOME CONVECTION TO OUR NW
THAT COULD BRING SCT COVERAGE TO THE NRN TIER AND I-77 CORRIDOR EARLY
THIS EVENING. HAVE UPDATED POP TO COVER THESE TRENDS. ALSO UPDATE
SKY...WINDS...T AND TD FOR CURRENT CONDITIONS.

AS OF 245 PM EDT THURSDAY...DESPITE HAVING A SHORT WAVE MOVE ACROSS
THE REGION EARLIER IN THE DAY AND HAVING DRIER AIR ALOFT...QUITE A
BIT OF CONVECTION HAS DEVELOPED ALONG THE SRN SLOPES OF THE BLUE
RIDGE WHICH IS NOW SLOWLY PUSHING INTO THE FOOTHILL AND PIEDMONT
SECTIONS OF NORTHEAST GEORGIA AND WESTERN SC. BASED ON THE MORNING
SOUNDINGS I DON/T SEE THE CONVECTION RUNNING INTO MUCH INHIBITION.
IN FACT...THE FORCING SHOULD IMPROVE OVER THE NEXT FEW HOURS AND THE
STORMS SHOULD GRADUALLY PUSH TO THE SOUTHEAST ACROSS THIS REGION.
THE DCAPE FROM THE SPC MESOANALYSIS ISN/T VERY HIGH IN THIS
AREA...THOUGH WE HAVE SEEN SOME ICY CORES UP AROUND 18-20KFT. THERE
WILL BE A MARGINAL DAMAGING WIND AND HAIL THREAT WITH THESE STORMS
OVER THE NEXT FEW HOURS. THEY ARE ALSO SLOW MOVING AND HAVE HAD A
TENDANCY TO BACK-BUILD...SO THERE WILL ALSO BE AN ISOLATED FLASH
FLOODING THREAT. ELSEWHERE...CONVECTION IS MUCH MORE SPOTTY OVER THE
REST OF THE FORECAST AREA. THERE WILL BE SOME INCREASE IN COVERAGE
OVER THE NEXT FEW HOURS...AND I HAVE LOW END CHANCE POPS OVER MOST
OF THE FA THROUGH SUNSET.

AREAS OF STRATUS AND VALLEY FOG ARE EXPECTED IN THE MOUNTAINS AGAIN
TONIGHT. THOUGH MCS DEBRIS MAY BRING MID AND HIGH CLOUD COVER IN
LATER TONIGHT...HURTING THE CHANCES FOR VALLEY FOG. AS FOR
CONVECTIVE CHANCES OVERNIGHT...A WEAKENING MCS COULD MOVE INTO THE
NC MTNS TOWARD SUNRISE...THOUGH I/M NOT SEEING ANY SIGN OF A
STRONGLY ORGANIZED MCS ON ANY OF THE CONVECTION ALLOWING MODELS.
MORE THAN LIKELY WE WILL HAVE TO WAIT UNTIL THE AFTN HOURS. DURING
THIS TIME THE NAM DEVELOPS STRONG LLVL CONVERGENCE OVER THE UPSTATE
AND SRN NC PIEDMONT. THE MODEL RESPONDS WITH AN AREA OF HEAVY
CONVECTIVE PCPN. THE GFS HAS A SOMEWHAT WEAKER RESPONSE...BUT LOOKS
SIMILAR IN THE MASS FIELDS. I/VE RAISED POPS INTO THE 40 TO 50
PERCENT RANGE AND THIS MAY END UP BEING A LITTLE LOW. MODEL
SOUNDINGS IMPLY THAT THE MID-LEVEL AIRMASS WILL BE FAIRLY MOIST
DURING THE AFTERNOON AND EARLY EVENING HOURS. THE WIND SHEAR WILL
ALSO BE RATHER WEAK. SPC DOES HAVE US UNDER A 5 PERCENT AREA FOR
SEVERE STORMS...AND WE/LL MENTION IT IN THE HWO...BUT I/D BE MORE
WORRIED ABOUT THE POTENTIAL FOR SLOW MOVING HEAVY RAIN PRODUCING
THUNDERSTORMS TOMORROW THAN WIND DAMAGE OR HAIL.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
AT 200 PM EDT THURSDAY...AN UPPER RIDGE WILL BE OVER THE SOUTHERN
PLAINS FRIDAY EVENING...WHILE AND UPPER TROUGH WILL BE ALONG THE
EAST COAST. THESE FEATURES PROGRESS SUCH THAT BY LATE SATURDAY...THE
RIDGE WILL BE CENTERED OVER MO...AND THE TROUGH AXIS OVER THE GULF
STREAM. BY SUNDAY NIGHT THE DEAMPLIFYING TROUGH AXIS WILL BE WELL
OFFSHORE...WHILE THE UPPER HIGH REMAINS OVER MO.

A COLD FRONT WILL CONTINUE TO MOVE SLOWLY SOUTH ACROSS OUR AREA ON
FRIDAY NIGHT...WITH CONVECTION LINGERING ALONG THE BOUNDARY INTO THE
EVENING. LOW LEVEL FLOW WILL HAVE A WNW DOWNSLOPE COMPONENT IN
ADVANCE OF THE FRONT...AND MODEL TIME HEIGHTS SHOW MOISTURE BE QUITE
SHALLOW UNTIL THE ACTUAL TIME OF FRONTAL PASSAGE. WITH THESE FACTORS
IN MIND...ONLY CHANCE POPS WILL BE CARRIED AT THIS TIME. THE FRONT
AND DRIFTS SLOWLY SOUTH OF OUR AREA ON SATURDAY...TAKING THE BEST
CHANCE OF PRECIPITATION WITH IT. DRIER AIR GRUDGINGLY MOVES IN
FROM THE NORTHEAST SUNDAY AND SUNDAY NIGHT.

TEMPERATURES WILL INITIALLY HAVE A REDUCED DIURNAL RANGE AS MOISTURE
AND CLOUDS COVER KEEP MINIMUMS NEAR NORMAL FRIDAY NIGHT...AND
MAXIMUMS BELOW NORMAL. MINIMUMS TEMPERATURES SUNDAY NIGHT WILL BE
SEVERAL DEGREES BELOW NORMAL AS POST FRONTAL COLD ADVECTION AND
REDUCED CLOUDS COVER ARRIVE.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
AS OF 215 PM THURSDAY...A STRONG UPPER RIDGE WILL BE CENTERED OVER
THE MID MS RIVER VALLEY ON MONDAY...WITH SURFACE HIGH PRESSURE
LOCATED FROM THE SOUTHERN APPALACHIANS...EASTWARD INTO THE ATLANTIC.
THE UPPER HIGH WILL PERSIST THROUGH THE WEEK WHILE THE SURFACE HIGH
WILL BE GRADUALLY SUPPRESSED SOUTHWARD OVER TIME AS AN UPPER TROUGH
DIGS ALONG THE EAST COAST BY LATE IN THE WEEK. A BACKDOOR COLD FRONT
WILL APPROACH THE AREA FROM THE NORTH BY LATE WEEK.

PRECIPITATION WILL BE SUPPRESSED THROUGH MID WEEK AS MID LEVEL
WARMING CAPS CONVECTION. SOME ISOLATED UPDRAFTS MAY BREAK THROUGH
THE CAP OVER THE HIGH ELEVATIONS EACH AFTERNOON MON-WED...BUT POPS
WILL BE BELOW CLIMO THROUGH WED. THE APPROACHING FRONT ON THU AND
DIMINISHING MID LEVEL CAPPING INVERSION WILL ALLOW CONVECTIVE CHANCES
TO INCREASE THU AFTERNOON WITH POPS NEAR CLIMO. TEMPS WILL START OFF
THE PERIOD ABOUT A CATEGORY BELOW AVERAGE...BUT INCREASE NEAR NEAR
NORMAL BY MIDWEEK...AND THEN A LITTLE ABOVE NORMAL BY LATE WEEK.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
AT KCLT...CANNOT COMPLETELY RULE OUT A CONVECTIVE CELL MOVING NEAR
THE AIRFIELD EARLY THIS EVENING. HOWEVER...CHC TOO LOW TO INCLUDE
ATTM. OTHERWISE...EXPECT FEW LOW VFR AND BKN HIGH CLOUDS THRU THE
EVENING. SKIES CLEAR OVERNIGHT WITH MVFR FOG FORMING BY MORNING.
LIGHT SW WIND BECOMES CALM OVERNIGHT. CONDITIONS SHUD QUICKLY
IMPROVE TO VFR AFTER DAYBREAK. LOOKS LIKE ANOTHER ROUND OF AT LEAST
SCT CONVECTION DURING THE AFTERNOON AS A WEAK BOUNDARY DROPS THRU
THE AREA. WINDS COULD BE S OF WEST DURING THE MORNING THEN GO NORTH
OF WEST DURING THE AFTERNOON. HOWEVER...GUIDANCE BLEND SHOWS LIGHT
NW IN THE MORNING INCREASING SLIGHTLY FOR THE AFTERNOON.

ELSEWHERE...CONVECTION RAPIDLY DIMINISHING THIS EVENING...SO NO
MENTION IN THE TAF. FEW LOW VFR AND BKN HIGH CLOUDS THRU THE EVENING
SCATTER OUT OVERNIGHT. HOWEVER...EXPECT A RETURN OF AT LEAST IFR MTN
VALLEY FOG WITH AT LEAST IFR CIGS. ELSEWHERE...MVFR FOG LIKELY WITH
IFR POTENTIAL AT KHKY/KAND. IFR STRATUS POSSIBLE...BUT GUIDANCE
SHOWING LIGHT W TO NW LOW LEVEL WINDS CONTINUING OVERNIGHT. SHUD BE
A QUICK RETURN TO VFR AFTER DAYBREAK. GENERALLY LIGHT TO CALM WIND
OVERNIGHT BECOMES LIGHT NW AFTER DAYBREAK. EXPECT ANOTHER ROUND OF
AT LEAST SCT CONVECTION DURING THE AFTERNOON AS A WEAK BOUNDARY
DROPS THRU THE AREA. COULD SEE SOME SW WIND AHEAD OF THE BOUNDARY
OUTSIDE OF THE MTNS WITH A RETURN TO NW FOR LATE AFTERNOON.

OUTLOOK...A DRIER PATTERN IS EXPECTED AS HIGH PRESSURE GRADUALLY
BUILDS IN FROM THE NORTH. LINGERING MOISTURE AND UPSLOPE FLOW MAY
RESULT IN MORNING RESTRICTIONS IN LOW CLOUDS AND FOG EARLY SATURDAY.
BUT CONSIDERABLY DRIER CONDITIONS ARE EXPECTED SATURDAY NIGHT INTO
NEXT WEEK.
