NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at Sep 3, 3:29 PM EST, 43 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 429 PM EDT MON SEP 3 2012 .SYNOPSIS... THE REMNANTS OF ISAAC WILL CONTINUE TO SLOWLY MOVE EASTWARD ACROSS THE OHIO RIVER VALLEY TONIGHT. AMPLE MOISTURE OUT AHEAD OF THIS SYSTEM WILL PERSIST OVER THE WESTERN CAROLINAS AND NORTHEAST GEORGIA THROUGH MIDWEEK BEFORE A COLD FRONT ARRIVES FROM THE NORTHWEST OVER THE WEEKEND. && .NEAR TERM /THROUGH TUESDAY/... AS OF 425 PM...CONVECTION INCREASING OUTSIDE OF THE MTNS AHEAD OF AN APPROACHING MCV. THIS IS ACTING ON THE VERY MOIST AND UNSTABLE AIR MASS TO KICK OFF SEVERAL BKN LINES OF CONVECTION WHICH ARE MOVING NE ACROSS THE AREA. EXPECT THIS ACTIVITY TO CONTINUE INTO THE EARLY EVENING BEFORE TAPERING OFF. HAVE INCREASED POP TO CATEGORICAL IN THESE AREAS. CONVECTION CURRENTLY MINIMAL ACROSS THE MTNS AS A SLIGHTLY DRIER AN MORE STABLE AIR MASS HAS MOVED IN BEHIND THIS CONVECTION. HAVE DROPPED POP BACK TO CHC THRU THE EARLY EVENING. EXPECT SHOWERS AND ISOLATED STORM TO RETURN TO THE MTNS AS MOISTURE MOVES BACK IN OVERNIGHT. THEREFORE...LET POP RETURN TO AT LEAST LIKELY IN THESE AREAS. MADE OTHER ADJUSTMENTS BASED ON CURRENT CONDITIONS. AS OF MID AFTERNOON...KGSP RADAR SHOWS SHOWERS AND THUNDERSTORMS BLOSSOMING OVER THE PIEDMONT AND UPSTATE...EAST OF REMNANT CLOUD BOUNDARY...WHERE DESTABILIZATION HAS ALLOWED SFC BASED CAPE TO CLIMB ABOVE 2500 J/KG. LOW LEVEL FORCING AND BUOYANCY SHOULD ALLOW THIS TREND TO CONTINUE THROUGH THE LATE AFTERNOON AND INTO THE EARLY EVENING. HEAVY RAIN REMAINS THE PRIMARY THREAT AS CONVECTIVE CLUSTERS MOVE FAIRLY SLOW BUT ELONGATE SW TO NE IN THE GENERAL DIRECTION OF MOVEMENT. CONFIDENCE NOT HIGH ENOUGH TO ISSUE A FLASH FLOOD WATCH AT THIS TIME...BUT THERE IS A DISTINCT POSSIBILITY THAT FLOODING COULD BECOME A PROBLEM OVER THE CLT METRO AREA LATE THIS AFTERNOON OR THIS EVENING. NOT MUCH HAS CHANGED TO EARLIER THINKING WITH REGARD TO THE FCST TONIGHT AND TUESDAY. THE WEAKENING UPPER LOW ASSOCIATED WITH REMNANT OF ISAAC WILL SLOWLY DEAMPLIFY AND STRETCH OUT ACROSS THE APPALACHIANS AND WRN CAROLINAS THROUGH LATE TUESDAY. SPOKES OF WEAK DPVA WILL PROVIDE UPPER SUPPORT FOR DEEP CONVECTION. MORE IMPORTANTLY...THE AIR MASS WILL REMAIN RICH WITH TROPICAL MOISTURE. A PLUME OF LOW LEVEL THETA-E AND PW IN EXCESS OF 2 INCHES WILL REMAIN IN PLACE. THE LOW LEVEL FLOW WILL ALSO RETAIN A SOUTHERLY UPSLOPE COMPONENT...WITH SOME CONVERGENCE OVER THE FOOTHILLS AND PIEDMONT MAXIMIZING IN THE AFTERNOON ON TUESDAY. THE MODELS RESPOND IN KIND WITH WIDESPREAD PRECIP COVERAGE FOR THE NEXT 24 HOURS. ESSENTIALLY...A SHOWER AND THUNDERSTORM COULD DEVELOP AT ANY TIME ACROSS THE ENTIRE FCST AREA THROUGH THE NEAR TERM...MODULATED BY DAYTIME HEATING. PRECIP CHANCES WILL BE SHOWN TO WANE TOWARD DAYBREAK TUESDAY...BUT WILL RECOVER QUICKLY WITH HEATING ON TUESDAY. SEE NO REASON TO THINK STORMS WILL BE ANYTHING LESS THAN NUMEROUS IN THE AFTERNOON...SO POP WAS RAISED TO LIKELY. TEMPS WILL BE MILD TONIGHT AND THEN ON THE COOL SIDE OF GUIDANCE TUESDAY. THE SRN PIEDMONT MAY WARM UP THE MOST TUESDAY AS THEY STAND THE BEST CHANCE OF BREAKING OUT AT SOME POINT. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... AS OF 230 PM EDT MONDAY... AT 00Z WEDNESDAY THE REMNANTS OF THE OHIO VALLEY UPPER LEVEL CYCLONIC CIRCULATION WILL BE IN THE PROCESS OF BEING PARTIALLY ABSORBED BY THE FAST WESTERLY FLOW ACROSS THE NORTHERN HALF OF THE COUNTRY. HOWEVER... A WEAK TROUGH/CYCLONIC SHEAR AXIS WILL HAVE SEPARATED FROM THE NORTHERN PART OF THE LOW AND WILL BE DRIFTING ACROSS THE FORECAST AREA WITH A ZONE OF CYCLONIC VORTICITY ADVECTION PROMOTING UPWARD MOTION. BY WEDNESDAY MORNING... THE NAM AND GFS PLACE THE AXIS OF THE MID LEVEL TROUGH BASICALLY NORTH/SOUTH OVER THE MOUNTAINS AND FOOTHILLS. LOW LEVEL AIR MASS REMAINS VERY MOIST IN ADVANCE OF THE TROUGH. MODEL PROFILES DISPLAY AFTERNOON CAPES GENERALLY IN THE 1000 TO 1500 J/KG RANGE... SO CONVECTIVE STORMS CERTAINLY APPEAR LIKELY. MODEST AMOUNTS OF CAPE PERSIST WELL INTO THE NIGHT... THUS NOCTURNAL SHOWERS AND THUNDERSTORMS ARE QUITE POSSIBLE. PRECIPITABLE WATER VALUES REMAIN HIGH AND WINDS THROUGH THE CLOUD LAYER DO NOT BECOME PARTICULARLY STRONG. LOCALLY HEAVY RAIN REMAINS A POSSIBILITY. DURING THURSDAY... THE TROUGH CONTINUES DRIFTING EAST ALLOWING DRIER AIR TO SPREAD INTO THE CWA FROM THE WEST. GFS HINTS AT A LITTLE MORE LINGERING MOISTURE THAN THE NAM AT THIS POINT. HAVE OPTED TO CONTINUE WITH CHANCE AND SLIGHT CHANCE POPS IN THE FAR WEST ON THURSDAY WITH CHANCE POPS CENTRAL AND EAST. CLOUDS AND SHOWERS WILL HOLD DAYTIME TEMPERATURES WEDNESDAY AND THURSDAY IN THE 80S WITH 70S IN THE MOUNTAINS... ALTHOUGH A LITTLE MORE SUN ON THURSDAY COULD BOOST AFTERNOON TEMPERATURES A FEW DEGREES. WARM AND MUGGY OVERNIGHT WEATHER WILL PERSIST WITH LOWS IN THE 60S AND LOWER 70S. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... AS OF 1145 AM EDT MONDAY...THE MEDIUM RANGE FCST PICKS UP AT 00Z ON FRIDAY WITH BROAD UPPER TROFFING OVER THE GREAT LAKES AND THE REMNANTS OF A WEAK UPPER LOW SPINNING OFF THE SE COAST. HEIGHTS ARE EXPECTED TO STEADILY LOWER AS THE UPPER TROF DEEPENS CONSIDERABLY OVER THE WEEKEND AND BECOMES POSITIVELY TILTED AS IT MOVES OVER THE CWFA. BY THE END OF THE PERIOD ON DAY 7...HEIGHTS SHOULD BEGIN RISING AS WEAK UPPER RIDGING STARTS TO BUILD IN. AT THE SFC...WE WILL BE IN AN ACTIVE PATTERN THRU THE WEEKEND WITH A FAIRLY ROBUST LOOKING SFC RIDGE LIKELY PUSHING INTO THE REGION EARLY NEXT WEEK AND DRYING/COOLING THINGS OFF BEYOND DAY 7. FRIDAY IS LOOKING MOSTLY DRY FOR THE UPSTATE AND PIEDMONT WITH A SOLID CHANCE FOR TSRA OVER THE NC MTS/FOOTHILLS. POPS RAMP UP ON SATURDAY AS THE MODELS DEVELOP A SFC LOW TO OUR WEST/SW AND PUSH ITS ASSOCIATED FRONTAL BNDY THRU THE CWFA LATE SAT/EARLY SUN. THERE COULD BE A GOOD POTENTIAL FOR ORGANIZED TS WITH THIS FROPA BASED ON CURRENT DEPICTIONS...SO THAT WILL NEED TO BE WATCHED CLOSELY IN THE COMING DAYS. IN THE WAKE OF THE FRONTAL BNDY...DRIER HIGH PRESSURE WILL BUILD IN AND CLEAR THINGS OUT. FOR THE TIME BEING...I HAVE HIGH END CHANCE POPS OVER MOST OF THE CWFA LATE SAT THRU SUN AFTERNOON WITH VALUES DROPPING ON MONDAY. THE LONG RANGE MODELS ARE IN PRETTY GOOD AGREEMENT WRT THE TIMING OF THE FROPA...BUT THE EVOLUTION OF THE SFC LOW DOES NOT MATCH UP VERY WELL AT THIS TIME. TEMPS ARE EXPECTED TO COOL THRU THE PERIOD WITH HIGHS AROUND NORMAL ON FRI AND VALUES ABOUT A CATEGORY BELOW NORMAL BY DAY 7. && .AVIATION /21Z MONDAY THROUGH SATURDAY/... AT KCLT...BKN LINE OF CONVECTION WILL MOVE ACROSS THE AIRFIELD BY 21Z AND CONTINUE FOR A COUPLE OF HOURS. WILL ADJUST TAF TO COVER THIS EVENT. AFTER 23Z...HAVE BACKED OFF ON RESTRICTIONS FOR NOW AS THERE MAY BE A LULL IN ACTIVITY IN THE WAKE OF THUNDERSTORMS... BUT AIR MASS RECOVERY COULD BE QUICK AND ADDITIONAL STORMS ARE POSSIBLE WELL INTO THE EVENING. THIS WILL BE HANDLED IN FUTURE AMENDMENTS. OTHERWISE...RICH LOW LEVEL MOISTURE WILL REMAIN IN PLACE. CEILING SHOULD GRADUALLY COME DOWN INTO IFR CATEGORY ACROSS THE PIEDMONT AFTER MIDNIGHT WITH FOG DEVELOPING TO AT LEAST MVFR CRITERIA. CONFIDENCE IS HIGH THAT CONDITIONS WILL BE AT LEAST MVFR. EXPECT A SLOW IMPROVEMENT TO MVFR DURING MID/LATE MORNING TUESDAY. ONCE THE CEILING LIFTS... RAPID CONVECTIVE DEVELOPMENT WILL TAKE PLACE AGAIN...EARLY TUESDAY AFTERNOON. WINDS WILL GENERALLY REMAIN S TO SW THROUGH THE PERIOD AWAY FROM NEARBY STORMS. ELSEWHERE...CONDITIONS SIMILAR TO KCLT WITH MAINLY VFR OUTSIDE STORMS AND MVFR/IFR INSIDE NUMEROUS SHOWERS AND STORMS. KAVL THE EXCEPTION WHERE CONVECTION HAS WANED AS A DRIER MORE STABLE AIR MASS HAS MOVED IN. EXPECT CONVECTION TO RETURN TO THE MTNS BY EVENING. THE CONVECTION SHOULD MAXIMIZE IN COVERAGE LATE THIS AFTERNOON AND EVENING AND THEN WANE LATER THIS EVENING. HOWEVER...EXPECT SOME SHOWERS TO CONTINUE ALL NIGHT LONG. CEILINGS WILL FALL AFTER SUNSET INTO THE MVFR CATEGORY AND THEN IFR DURING THE EARLY MORNING HOURS AT ALL SITES WITH FAIRLY HIGH CONFIDENCE. MORE CONVECTION WILL DEVELOP BY MIDDAY TUESDAY. OUTLOOK...DEEP MOISTURE WILL PERSIST ACROSS THE REGION THROUGH AT LEAST WEDNESDAY. LOW CLOUD/FOG RESTRICTIONS WILL BECOME INCREASINGLY WIDESPREAD AND PERSISTENT AS SHOWER COVERAGE REMAINS HIGH TUE INTO WED. GRADUAL DRYING FROM THE WEST IS POSSIBLE THU...BUT MORE LIKELY ON FRI.

SCATTERED TO NUMEROUS THUNDERSTORMS WILL CONTINUE ACROSS THE AREA. THE MOST LIKELY THREAT WITH THE THUNDERSTORMS WILL BE VERY HEAVY RAINFALL AND OCCASIONAL CLOUD TO GROUND LIGHTNING STRIKES. IF MULTIPLE THUNDERSTORMS AFFECT THE SAME LOCATION... ISOLATED FLASH FLOODING OF STREAMS AND CREEKS COULD RESULT. IN ADDITION... A FEW THUNDERSTORMS MAY BECOME STRONG ENOUGH TO PRODUCE BRIEF BUT DAMAGING WIND GUSTS. SHOWERS AND THUNDERSTORMS WILL BECOME LESS NUMEROUS DURING THE OVERNIGHT HOURS... BUT THE POSSIBILITY OF ISOLATED THUNDERSTORMS WITH HEAVY RAIN WILL PERSIST. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY. SHOWERS AND THUNDERSTORMS WILL DEVELOP AGAIN TUESDAY THROUGH WEDNESDAY...AND POSSIBLY INTO THURSDAY. LOCALIZED FLASH FLOODING IS QUITE POSSIBLE THIS WEEK...BUT UNCERTAINTY REMAINS TOO HIGH TO DEFINE LOCATIONS THAT MIGHT REQUIRE A FLASH FLOOD WATCH. .SPOTTER INFORMATION STATEMENT... SKYWARN SPOTTERS ARE REQUESTED TO FORWARD ANY REPORTS OF HAIL... WIND DAMAGE... OR FLASH FLOODING TO OUR OFFICE.
