Hail and Damaging Wind in South Carolina, June 8, 2014

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
515 PM EDT SUN JUN 8 2014

.SYNOPSIS...
ANOTHER WEAK COLD FRONT WILL REACH THE AREA FROM THE NORTHWEST
MONDAY...THEN WILL MOVE NORTH AS WARM FRONT AND LEAVE THE AREA ON
TUESDAY. A MOIST SOUTH TO SOUTHWEST FLOW WILL PERSIST ACROSS OUR
REGION AT LEAST THROUGH MID WEEK.

&&

.NEAR TERM /THROUGH MONDAY/...
AS OF LATE AFTERNOON...SOME THUNDERSTORMS CONTINUE TO MOVE ACROSS
THE SRN FRINGE OF THE CLT METRO AREA AND EAST OF I-77...BUT COVERAGE
HAS DECREASED AND SHOULD CONTINUE TO DO SO OVER THE EASTERN ZONES.
MEANWHILE...SOME DESTABILIZATION HAS OCCURRED OVER THE MTNS AND BLUE
RIDGE...ALLOWING A FEW NEW STORMS TO DEVELOP. WILL MAINTAIN A CHANCE
POP OVER THE MTNS AND NC FOOTHILLS TO ACCOUNT FOR THIS. POP WAS
LOWERED TO SLIGHT CHANCE OVER NE GEORGIA AND MOST OF THE UPSTATE
BASED ON LACK OF CU DEVELOPMENT IN SATELLITE IMAGERY AND WESTERLY
DOWNSLOPE FLOW.

PREVIOUS DISCUSSION...

AS OF 245 PM...CLUSTER OF CONVECTION ALONG AND EAST OF I-77 WILL
SLOWLY MOVE EAST THRU THE AFTERNOON. A SEVERE STORM CANNOT BE RULED
OUT...ESPECIALLY NEAR THE NC/SC BORDER. ELSEHWERE...MAINLY ISOLATED
CONVECTION AT BEST IS EXPECTED THRU EARLY EVENING. EVEN THIS MAY BE
GENEROUS AS THE LATEST GUIDANCE SUGGESTS WEAKER INSTABILITY WITH
POSSIBLY SOME NVA MOVING THRU. THAT SAID...THE BEST CHC WILL BE
ACROSS THE NC MTNS AND I-40 CORRIDOR WHERE THE CONVECTION ALLOWING
MDLS SHOW LINGERING ACTIVITY IN WEAK LOW LEVEL CONVERGENCE. SHUD BE
ANOTHER NIGHT WITH LOW CLOUDS AND FOG DEVELOPING BY DAYBREAK. LOWS
WILL BE NEAR TO SLIGHTLY ABOVE NORMAL.

A WEAK SHORT WAVE CROSSES THE AREA MONDAY WITH A RETURN TO A MOIST
UNSTABLE AIR MASS. PREVIOUSLY...SOME MDLS WERE BUILDING IN A DRY
HIGH PRESSURE AREA INTO THE AREA KEEPING MOISTURE AND INSTABILITY TO
A MINIMUM. THESE MDLS HAVE BACKED OFF ON THAT SCENARIO. HOWEVER...A
GUIDANCE BLEND DOES SHOW AN OVERALL DOWNWARD TREND TO POP.
THEREFORE...HAVE GONE WITH SCT COVERAGE FOR THE NC MTNS WITH
ISOLATED ELSEWHERE. GIVEN THE RELATIVELY WEAK INSTABILITY AND
SHEAR...SVR STORM CHC WILL BE LOWER. HIGHS WILL BE NEAR TO A LITTLE
ABOVE NORMAL.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
AT 1130 AM EDT SUNDAY...GIVEN THE PROXIMITY OF A BAND OF DEEP LAYER
RH...CANNOT TOTALLY RULE OUT AT LEAST ISOLATED DEEP CONVECTION
LINGERING INTO THE LATE NITE HOURS ON MONDAY. STILL EXPECTING THE
MEAN FLOW REGIME ATOP THE CWFA TO INCREASE THROUGH TUESDAY AS
CYCLONE CENTER LIFTS NNEWD INTO THE OHIO VALLEY. AS TEMPERATURES
WARM TO FEW DEG F ABOVE PERSISTENCE...STRONG HTG/MOIST BLYR SHOULD
PROMOTE POCKETS OF MODERATE INSTABILITY. BASED ON THIS...WILL PLAN
ON CREEPING DIURNALLY FAVORED POP UPWARD TO ABOVE CLIMO VALUES.
GIVEN THE THERMODYNAMIC ENVIRONMENT...FEEL THAT A FEW SVR STORMS ARE
PROBABLE.

A MOIST AND POTENTIALLY ACTIVE PATTERN SHOULD CONTINUE THROUGH THE
LATTER HALF OF THE PERIOD WITHIN MODERATE SSW FLOW. GIVEN THE
PROGGED ABOVE NORMAL PWAT VALUES...WOULD EXPECT SCATTERED TO NUMEROUS
DIURNALLY ENHANCED SHOWERS AND THUNDERSTORMS WITH A FEW STG TO SVR
STORMS NOT OUT OF THE QUESTION INTO WEDNESDAY EVENING.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
AT 200 PM EDT SUNDAY...MEDIUM RANGE BEGINS AT 00Z THURSDAY.
AFTER AN CLOSED 500MB LOW OPENS OVER ILLINOIS LATE WED...ITS
ASSOCIATED TROUGH WITH AXIS TO THE MISS DELTA AT 00Z THURS WILL
CONTINUE TO MOVE SLOWLY EAST AT DAMPEN OUT AS IT CROSSES OUR REGION
THURS NIGHT. A SERIES OF SHORTWAVES WILL MOVE THROUGH THE WEST TO
EAST MID LEVEL FLOW IN LATE WEEK AND THROUGH THE WEEKEND. LOW LEVEL
FLOW IN OUR AREA WILL BE GENERALLY FROM THE SOUTH TO WEST...BUT AT
TIMES THERE WILL BE A LIGHT SE FLOW INTO THE MOUNTAINS...ESPECIALLY
IN NC...WHICH WOULD ENHANCE CONVECTIVE DEVELOPMENT IN THAT AREA.

THE GFS CONTINUES TO PERCOLATE TROPICAL DEVELOPMENT NEAR THE YUCATAN
LATE IN THIS PERIOD WITH SLOW MOVEMENT TOWARD FLORIDA EARLY NEXT
WEEK. THE ECMWF AND CANADIAN DOES NOT SHOW ANY SUCH DEVELOPMENT.
HIGH TEMPS WILL BE NEAR NORMAL...BUT SLIGHTLY COOLER THURS WITH THE
HEIGHT FALLS ASSOCIATED WITH THE DAMPENING TROUGH. CONSIDERING THE
CLOUD COVER AND HIGHER DEW POINTS...MIN TEMPS WILL TEND TO BE A
LITTLE ABOVE NORMAL.

&&

.AVIATION /21Z SUNDAY THROUGH FRIDAY/...
AT KCLT...SH/TSRA MOVING ACROSS AIRFIELD WILL BE EAST OF THE AREA BY
20Z. CANNOT RULE OUT ADDITIONAL CONVECTION THRU SUNSET...BUT CHC
WILL BE LOWER. WILL KEEP VCSH IN AFTER 20Z TO COVER...BUT VFR SHUD
PREVAIL. WITH LINGERING LOW LEVEL MOISTURE AND DEVELOPING
INVERSION...EXPECT MVFR VSBY AND CIGS TO RETURN OVERNIGHT WITH CIGS
DROPPING TO IFR BEFORE DAYBREAK. A SLOW IMPROVEMENT TO MVFR BY MID
MORNING THEN VFR AROUND NOON MONDAY WITH ONLY SCT CU FOR THE EARLY
AFTERNOON. CHC OF CONVECTION MON TOO LOW TO INCLUDE FOR NOW. SLY
WIND THIS AFTERNOON BECOMES SELY THIS EVENING THEN CALM OVERNIGHT.
SWLY WIND EXPECTED MON.

ELSEWHERE...CONVECTION MOST LIKELY AT KHKY THRU THE AFTERNOON...SO
HAVE INCLUDED A VCTS THERE. HOWEVER...CHC MUCH LOWER ELSEWHERE SO
HAVE REMOVED ALL WORDING ATTM. OTHERWISE...EXPECT VFR INTO THE
EVENING WITH A RETURN TO MVFR THEN IFR OVERNIGHT FOR ALL BUT KAND.
CIGS SHUD LIFT OT VFR BY MID MORNING OR NOON. CHC OF CONVECTION MON
TOO LOW TO INCLUDE FOR NOW. SWLY WIND TURNS N TO NW OVERNIGHT OR
CALM...WITH SWLY WINDS MONDAY.

OUTLOOK...LOW LEVEL MOISTURE AND A WEAK BOUNDARY IN THE VICINITY
WILL ALLOW MAINLY DIURNAL SHRA/TSRA TO FORM EACH AFTERNOON THROUGH
THE MIDDLE OF THE WEEK. THE BEST CHANCE OF RESTRICTIONS WILL BE IN
TSRA AND ALSO IN THE MTN VALLEYS EACH MORNING WHERE LOW CLOUDS AND
FOG MAY FORM.
