AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 130 PM EDT WED SEP 9 2009 .SYNOPSIS... A HIGH PRESSURE WEDGE WILL REMAIN OVER INLAND AREAS WHILE A STATIONARY FRONT REMAINS OFFSHORE THROUGH THE WEEKEND. THE OFFSHORE FRONT MAY LIFT NORTH AS A WARM FRONT EARLY NEXT WEEK WHILE THE INLAND WEDGE RETREATS TO THE N...POSSIBLY ALLOWING A COLD FRONT TO ENTER FROM THE W. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... WEDNESDAY AFTERNOON...AN UPPER LEVEL LOW WAS CROSSING THE CENTRAL APPALACHIANS. ON THE PERIPHERY OF THE UPPER LOW...SUBTLE 500 MB HEIGHT FALLS/CAA AND A SHORTWAVE WILL COMBINE WITH THE SEA BREEZE AND A WEAK SURFACE BOUNDARY NEAR THE SAVANNAH RIVER TO SUPPORT. ISOLATED THUNDERSTORMS HAD DEVELOPED NEAR THE SURFACE BOUNDARY ACROSS FAR INLAND SE GA COUNTIES. ADDITIONAL ISOLATED/SCATTERED THUNDERSTORMS WILL DEVELOP ACROSS INLAND COUNTIES NEAR THE SURFACE BOUNDARY...ALONG THE SEA BREEZE AND ALONG OUTFLOW FROM EARLIER/ONGOING CONVECTION THIS AFTERNOON/EVENING. POOLING OF SURFACE DEWPOINTS AROUND 70F NEAR THE SE GA SURFACE BOUNDARY HAS YIELDED SBCAPES AS HIGH AS 3000 J/KG...TAPERING TO 1000-2000 J/KG WHERE LOWER DEWPOINTS HAD SPREAD INTO N COUNTIES. INSTABILITY AND 0-6 KM BULK SHEAR RANGING FROM 20-25 KT S TO 30-35 KT N... 500 MB TEMPS RANGING FROM -8C TO -9C S TO -10C TO -11C N...WET BULB ZERO HEIGHTS 11-11.5 KFT AND DOWNDRAFT CAPES EXCEEDING 1000 J/KG SUGGEST THE POTENTIAL FOR MULTICELL THUNDERSTORMS WITH ISOLATED DAMAGING WIND GUSTS AND LARGE HAIL. ACCORDINGLY...THE SPC DAY 1 CONVECTIVE OUTLOOK WAS UPGRADED TO INCLUDE A 5 PERCENT RISK OF SEVERE THUNDERSTORMS ALONG/W OF I-95...AND THE HAZARDOUS WEATHER OUTLOOK WAS UPDATED TO INCLUDE ISOLATED SEVERE THUNDERSTORMS. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM THURSDAY/... THUNDERSTORMS SHOULD UNDERGO DIURNAL WEAKENING THIS EVENING...ALTHOUGH THE INFLUENCE OF THE UPPER LOW MAY MAINTAIN THE THREAT OF THUNDER ACROSS INLAND COUNTIES WELL INTO THE NIGHT. MEANWHILE...THE UPPER LEVEL LOW WILL CONTINUE TO SLIDE SE WHILE THE SFC HIGH PRES INLAND AND OFFSHORE STATIONARY FRONT REMAIN IN PLACE. SEVERAL MIDLVL SHORTWAVE TROF AXES LOOK TO ROTATE THROUGH THE AREA OVERNIGHT...BATTLING OVERNIGHT SUBSIDENCE TO PRODUCE A FEW ISOLD SHWRS INLAND. WILL MAINTAIN MENTION OF SLGT CHC POPS AWAY FROM THE COAST. TEMPS WILL CONTINUE TO RUN SEASONABLY MILD TNGT...WITH LOWS EXPECTED IN THE MID 60S AWAY FROM THE COAST AND ARND 70 NEAR THE SHORES. && .LONG TERM /THURSDAY THROUGH TUESDAY/... THE LARGE UPPER LEVEL TROUGH WILL REMAIN OVER THE ERN CONUS WITH ITS CENTER SHIFTING FROM THE OH RIVER VALLEY INTO THE NORTHEAST STATES. AT THE SFC...THE EVER-PRESENT HIGH PRES WEDGE WILL GENERALLY REMAIN IN PLACE WHILE A STATIONARY FRONT MEANDERS OFFSHORE. WITH THE UPPER LOW PULLING OFF TO THE NE...THIS WILL DRAG ADDITIONAL MOISTURE IN FROM THE SW ON ITS BACKSIDE. THE ADDITIONAL MOISTURE COMBINED WITH SEVERAL MIDLVL SHORTWAVE DISTURBANCES ROTATING AROUND THE LONGWAVE TROUGH WILL MAKE FOR ISOLD TO SCATTERED PRECIPITATION COVERAGE THROUGH THE END OF THIS WORKWEEK. THE CHC RANGE POPS WILL BE MAINLY CONFINED TO THE SRN HALF OF THE CWFA WHICH WILL BE IN CLOSER PROXIMITY TO THE MEANDERING OFFSHORE FRONT ALONG WITH THE DEEPER MOISTURE. TEMPS WILL CONTINUE TO RUN NEAR CLIMATOLOGICAL NORMS THROUGH THE END OF THIS WEEK. FOR THE START OF NEXT WEEK...THERE ARE SOME DIFFERING IDEAS SO HAVE OPTED TO STICK NEAR HPC THINKING WHICH SHOWS THE OFFSHORE FRONT LIFTING N AS A WARM FRONT THROUGH THE AREA SUN AND SETTLING N OF THE AREA MON INTO TUE. AT THE SAME TIME...THE LARGE LONGWAVE TROUGH OVER THE ERN CONUS WILL LIFT OUT...MAKING FOR A TRANSITIONAL ENVIRONMENT BETWEEN THIS EXITING TROUGH AND ANOTHER DEVELOPING OVER THE CENTRAL CONUS. THROUGH LITTLE SUPPORT WILL BE AVAILABLE FOR PRECIP DEVELOPMENT...THESE IS ALSO LITTLE TO SUPPRESS DEVELOPMENT SO HAVE MAINTAINED 20/30 POPS FOR THE EARLY PORTION OF NEXT WEEK. TEMPS STILL LOOK TO RUN WITHIN A FEW DEGREES OF NORMAL FOR THE PERIOD. && .AVIATION /18Z WEDNESDAY THROUGH SUNDAY/... VFR CONDITIONS WILL MOST LIKELY PREVAIL THROUGH THIS EVENING...ALTHOUGH THERE REMAINS A SMALL CHANCE THAT ISOLATED SHOWERS/THUNDERSTORMS COULD DEVELOP NEAR OR ADVANCE INTO THE TERMINALS WITH GUSTY/SHIFTING WINDS AND BRIEF SUB-VFR CONDITIONS THROUGH THIS EVENING. LOW LEVEL MOISTURE COULD THEN SUPPORT A PERIOD OF MVFR OR LOWER CONDITIONS LATER TONIGHT INTO EARLY THURSDAY...ESPECIALLY AT KSAV. ISOLATED TO SCATTERED SHOWERS/THUNDERSTORMS COULD DEVELOP IN THE VICINITY OF TERMINALS...ESPECIALLY KSAV...WEDNESDAY MIDDAY. HOWEVER...ANY THUNDERSTORMS ARE MORE LIKELY TO DEVELOP AFTER THE 18Z TAF PERIOD. EXTENDED AVIATION OUTLOOK...MOSTLY VFR WEATHER TO PREVAIL THROUGH SUNDAY WITH ONLY SMALL PROBABILITIES OF ANY STRATUS/FOG AND/OR PRECIPITATION. && .MARINE... LOW PRESSURE OFF THE MID ATLANTIC STATES TODAY AND TONIGHT WILL MOVE INTO THE DELMARVA AREA THURSDAY...AS HIGH PRESSURE FROM THE NORTH PERSISTS ACROSS THE LOCAL WATERS. THAT HIGH WILL BREAK INTO TWO SEPARATE CENTERS ON FRIDAY...WITH THE ORIGINAL CENTER MOVING OFF NEW ENGLAND. THE SECOND HIGH PRESSURE SYSTEM WILL FORM OVER THE CAROLINAS AND VA AND SHIFT EAST INTO THE ATLANTIC. MEANWHILE A STATIONARY FRONT ACROSS FL WILL ATTEMPT TO PUSH NORTHWARD SATURDAY AND SUNDAY...BUT ANOTHER AREA OF HIGH PRESSURE BUILDING OUT OF SOUTHERN CANADA AND INTO THE EAST AND NE PARTS OF THE COUNTRY WILL LIKELY BLOCK THE FRONT FROM MOVING TOO FAR NORTH. ONE OR TWO WAVES OF LOW PRESSURE MAY FORM ALONG THE FRONT DURING THE WEEKEND...BUT ODDS STRONGLY FAVOR ANY AREAS OF LOW PRESSURE TO REMAIN SOUTH OF THE COASTAL WATERS. TODAY...A MODEST SURGE OF NE WINDS 10-15 KT WILL GIVE WAY TO THE SEA BREEZE CIRCULATION THIS AFTERNOON. SEAS WILL BE A COMBINATION OF SMALL 2 FOOT EAST AND SE SWELL...AND A 2 OR 3 FOOT WIND WAVE. TONIGHT...EASTERLY WINDS WILL BACK TO NE OVERNIGHT...AND ANOTHER SMALL SURGE WILL OCCUR TOWARD DAYBREAK THURSDAY. HOWEVER...WINDS NO MORE THAN 10-15 KT AND SEAS NO HIGHER THAN 2 TO 3 FT. THURSDAY AND THURSDAY NIGHT...SEA BREEZE CIRCULATION WILL AGAIN ALLOW FOR WINDS TO VEER TO EASTERLY IN THE AFTERNOON AND EVENING...BEFORE BACKING TO NE LATE AT NIGHT. LITTLE CHANGE IN WINDS AND SEAS. FRIDAY THROUGH SUNDAY...WE ARE LOOKING FOR AT LEAST SOME INCREASE IN WINDS AND SEAS...DEPENDENT UPON HOW MUCH PINCHING OCCURS BETWEEN HIGH PRESSURE TO THE NORTH AND LOWER PRESSURE TO THE SOUTH. GIVEN UNCERTAINTIES AT THIS TIME WE WILL FORECAST NO MORE THAN 15 KT WINDS AND 4 FOOT SEA. THIS IS IN LINE WITH NEIGHBORING WEATHER FORECAST OFFICES...BUT GIVEN INDICATIONS OF A DECENT PINCHING TO DEVELOP WE CERTAINLY MAY NEED TO BUMP UP WINDS AND SEAS IN LATER FORECASTS. && .CHS WATCHES/WARNINGS/ADVISORIES...
