AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 137 PM EDT TUE JUL 24 2012 .SYNOPSIS... ATLANTIC HIGH PRESSURE WILL REMAIN SOUTH OF THE AREA THROUGH THE WEEK AS A TROUGH OF LOW PRESSURE PERSISTS INLAND. A WEAK COLD FRONT MAY APPROACH EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... STILL CLEAR ACROSS THE FORECAST AREA AS THE CAP IS HOLDING THE ATMOSPHERE IN CHECK. HOWEVER A CUMULUS FIELD IS DEVELOPING ACROSS MOST OF SOUTHEAST GEORGIA AND AM WATCHING WHAT APPEARS TO BE A DEVELOPING MCS ACROSS SOUTHWEST VIRGINIA MOVING SOUTHEAST. THE MAIN CONCERN THE REST OF THE AFTERNOON IS THE POTENTIAL OF SEVERE STORMS PUSHING INTO THE AREA FROM THE WEST AND NORTHWEST AS IT DEVELOPS ALONG AN INLAND SURFACE TROUGH. THE BEST CHANCE OF SEVERE STORMS LOOKS TO BE ACROSS SOUTHERN SOUTH CAROLINA...MAINLY IF THE UPSTREAM ACTIVITY ACROSS VA HOLDS TOGETHER AS IT MOVES TOWARD THE COAST...ALTHOUGH IT WILL LIKELY BE EVENING BY TIME IT GETS INTO SOUTHEAST SOUTH CAROLINA. HOWEVER...LESS ORGANIZED PULSE-TYPE SEVERE STORMS COULD OCCUR BEFORE ANY MCS DEVELOPS...ALTHOUGH IT WILL TAKE UNTIL CONVECTIVE TEMPS IN THE MID 90S ARE REACHED. PREFER TO WAIT A BIT TO BEEF UP THE SEVERE THREAT BUT WILL CONSIDER DOING SO WITH THE REGULAR UPDATE LATER THIS AFTERNOON. A STRONG OFFSHORE WIND COMPONENT TODAY WILL HELP KEEP THE SEA BREEZE PINNED NEAR THE COAST AND ALSO HELP PUSH TEMPS INTO THE MID TO UPPER 90S. MODERATE LEVELS OF HUMIDITY WILL PUSH HEAT INDICES AS HIGH AS ABOUT 105 DEGREES. && .SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/... TONIGHT...THE FORECAST COMPLEXITY GOES UP CONSIDERABLY BY THE EARLY EVENING AND CONTINUES THROUGH THE OVERNIGHT. WITHIN THE BELT OF BETTER FLOW BETWEEN THE RIDGE TO THE WEST AND THE TROF MOVING INTO THE NORTHEAST...A MCS FEATURE IS EXPECTED TO INITIATE ACROSS THE OHIO VALLEY AND PROPAGATE TO THE SOUTHEAST. THIS FEATURE SHOULD BE MOVING INTO THE LEE OF THE APPALACHIANS IN THE MID TO LATE AFTERNOON HOURS...CLOSELY COINCIDING WITH THE TIME OF MAX HEATING. VARIOUS MODEL SOLUTIONS...INCLUDING THE HI-RES WRF RUNS FEATURE A DEEP LAYER STEERING FLOW THAT IS NORTH TO NORTHWEST THROUGH 00Z. ON THIS TRACK...THE UPSTREAM MCS SHOULD BE DIRECTED TOWARD THE FORECAST AREA IN THE EARLY EVENING TIME FRAME. ASSUMING THE PRESENCE OF THE MCS...IT SHOULD BE MOVING INTO AN UNTAPPED ATMOSPHERE ACROSS SOUTHERN SOUTH CAROLINA DURING THIS TIME...MARKED BY CAPE VALUES ON THE ORDER OF 2500-3000 J/KG. WITH MODEL SOUNDINGS DEPICTING A NEAR STORM ENVIRONMENT DEFINED BY DCAPE VALUES IN THE 1000-1200 J/KG RANGE...DELTA THETA E VALUES UPWARDS OF 30 AND STEEP LOW LEVEL LAPSE RATES...IT STANDS TO REASON THAT THE CONVECTION WILL BE ABLE TO MAINTAIN ITSELF INTO SOME PORTION OF THE FORECAST AREA. THE PRIMARY SEVERE THREAT WILL COME IN THE FORM OF DAMAGING WIND GUSTS ASSOCIATED WITH THE MCS COLD POOL. THE PRECISE INITIATION...STRENGTH AND TRACK OF THE UPSTREAM MCS IS VITAL TO THE FORECAST AND THAT IS STILL A BIT OF A MYSTERY AT THIS POINT. HOWEVER...WE HAVE TRENDED THE FORECAST TOWARD THIS SOLUTION WITH A TIER OF CHANCE POPS BETWEEN 00-03Z FOR SOUTHERN SOUTH CAROLINA. ITS A BIT OF A BROAD BRUSH AT THIS POINT...AND THE DAY SHIFT WILL BE ABLE TO BETTER FINE TUNE IT AS THE MESOSCALE FEATURES COME INTO BETTER FOCUS. SPC HAS EXPANDED THE SLIGHT RISK TO INCLUDE LOCATIONS DOWN TO THE SAVANNAH RIVER...AND WE HAVE MAINTAINED MENTION IN THE HWO. WEDNESDAY...DEEP LAYERED RIDGING TO THE WEST ACROSS THE TN VALLEY AND GULF COAST REGION WILL ATTEMPT TO PUSH EAST...BUT IT IMPEDED IN DOING SO BY WEAK PERTURBATIONS WITHIN THE NW FLOW ALOFT BETWEEN THE RIDGE AND AN ATLANTIC TROUGH. MEANWHILE...THE LEE SIDE TROUGH WILL HAVE WEAKENED FROM PREVIOUS DAYS AS THE SUBTROPICAL RIDGE IS FOUND ELONGATED ACROSS SOUTHERN FL INTO THE GULF OF MEXICO. UNLESS THERE IS INDEED AN MCS THAT MOVES THROUGH TONIGHT THAT IS FOLLOWED BY A DRIER AND MORE STABLE AIR MASS...HERE IS WHAT WE CURRENTLY ANTICIPATE TO TRANSPIRE. EVEN IF THERE IS AN MCS THAT MOVES THROUGH TONIGHT...WEDNESDAY WILL BE ANOTHER HOT DAY. 850 MB TEMPS ARE 20-21C...AND 1000-850 MB THICKNESS IS 1430-1440 METERS. THAT ALONG WITH A DEEP OFFSHORE FLOW THROUGHOUT THE TROPOSPHERE ABOVE THE BOUNDARY LAYER SUPPORTS MAX TEMPS IN THE MID TO UPPER 90S AWAY FROM THE COAST. IF OUR DEW POINT FORECAST COMES TO FRUITION...WITH AFTERNOON VALUES IN THE LOWER AND MIDDLE 70S...THE RESULTING HEAT INDICES WILL PEAK IN THE 105-110 DEGREE RANGE. BUT IF THERE IS DRIER AIR FOLLOWING THE MCS...THEN THESE VALUES MAY NEED TO BE ADJUSTED DOWNWARDS IN SUBSEQUENT FORECASTS. WITH LESS FORCING FROM THE PIEDMONT TROUGH AND LITTLE TO NO SUPPORT ALOFT...OUR RAIN CHANCES WILL BE SUPPLIED BY THE SEA BREEZE AND ANY OTHER MESOSCALE BOUNDARIES THAT FORM. BUT THERE LOOKS TO BE A DECENT CAP IN PLACE...SO WE/LL LIMIT COVERAGE TO 20-30 PERCENT. THURSDAY...THE TROUGH ALOFT IN THE ATLANTIC PULLS FURTHER AWAY AND THIS ALLOWS FOR THE ANTICYCLONE ALOFT TO SETTLE ATOP THE FORECAST AREA. AS THIS OCCURS...THE INLAND TROUGH STRENGTHENS AGAIN IN ITS TYPICAL POSITION ACROSS THE SC PIEDMONT SW TO CENTRAL GA. THIS FEATURE WILL COMBINE WITH THE TYPICAL SEA BREEZE...LAKE BREEZES OFF MARION AND MOULTRIE...UPSTREAM OUTFLOWS AND DIFFERENTIAL HEATING BOUNDARIES TO GENERATE A INCREASE IN COVERAGE FROM WEDNESDAY. HOWEVER...THERE IS STILL A CAP IN PLACE...THUS STORM COVERAGE WILL BE IN THE A TYPICAL ISOLATED TO SCATTERED RANGE. TEMPS AT 850 MB HOLD FAIRLY CONSTANT AROUND 20-21C...AND THERE IS LITTLE CHANGE IN THE 1000-850 MB THICKNESS. WITH A CONTINUED OFFSHORE FLOW THROUGHOUT MUCH OF THE VERTICAL COLUMN...WE LOOK FOR MAX TEMPS TO AGAIN REACH THE MID AND UPPER 90S. WHEN COMBINED WITH DEW POINTS IN THE 70S...MAXIMUM HEAT INDICES WILL CLIMB CLOSE TO OUR HEAT ADVISORY CRITERIA OF 110 DEGREES. FRIDAY...ALTHOUGH A POTENT SHORT WAVE WILL BE WEAKENING WITH TIME AS IT TRAVELS EAST AND SE ACROSS SOUTHERN CANADA DURING THE MIDDLE OF THE WEEK...IT IS STILL STRONG ENOUGH TO HELP IN THE BEGINNING STAGES OF ANOTHER TROUGH IN THE EAST AS IT DROPS SE THROUGH THE GREAT LAKES. FOR US THE FLOW IS QUASI-ZONAL...BUT IS ENOUGH TO FORCE THE INLAND TROUGH TO SHIFT A LITTLE CLOSER TO THE LOCAL AREA. IF THIS COMES TO PASS...THEN SHOWER/T-STORM CHANCES MIGHT BE ON THE INCREASE. FOR NOW WE PREFER A MORE CONSERVATIVE FORECAST IN THE SCATTERED RANGE. THERE IS LITTLE CHANGE IN LOW LEVEL TEMPS AND/OR LOW LEVEL THICKNESS VALUES...AND WITH THE DEEP WESTERLY FLOW TO DOWNSLOPE OFF THE MOUNTAINS...WE MIGHT BE LOOKING AT OUR HOTTEST DAY OF THE WEEK. WE CANNOT ENTIRELY RULE OUT A FEW SPOTS HITTING THE CENTURY MARK PRIOR TO ANY CONVECTION FORMING...BUT MID TO UPPER 90S LOOKS LIKE A MORE REASONABLE FORECAST SINCE HEIGHTS ALOFT MAY LOWER SLIGHTLY. HEAT ADVISORIES ARE POSSIBLE WITH HEAT INDICES OF 110 DEGREES OR GREATER. WHILE MAX TEMPS EACH DAY WILL BE FAR ABOVE SEASONAL NORMS...THEY CURRENTLY LOOK TO BE BELOW ANY RECORDS. INSTEAD WE MIGHT BE CLOSE TO SOME OF OUR RECORD HIGH MINIMUMS FOR THE NIGHTTIME LOWS. && .LONG TERM /FRIDAY NIGHT THROUGH MONDAY/... THE GREAT LAKES SHORT WAVE MOVES INTO THE NE SATURDAY...WHICH AMPLIFIES THE TROUGH IN THE EAST. THE APEX OF THIS TROUGH STRETCHES SOUTH TO GA/FL...AND IT MOVES LITTLE THROUGH SUNDAY. BEYOND THAT FOR EARLY NEXT WEEK WE/RE NOT YET CERTAIN AS TO WHETHER OR NOT ADDITIONAL SHORT WAVES DROP INTO THE TROUGH TO MAINTAIN ITS PLACE OVER THE EAST AND SE...OR DOES IT REMAIN VOID OF ANY PERTURBATIONS AND INSTEAD BEGINS TO LIFT OUT. AT THE SURFACE OUR CONFIDENCE IS GOOD THAT THE INLAND TROUGH WILL REMAIN NOT FAR FROM THE LOCAL AREA THROUGH THE WEEKEND. BUT THEN THE QUESTION REMAINS IS TO WHETHER OR NOT A COLD FRONT IS ABLE TO REACH THE FORECAST AREA EARLY NEXT WEEK. CLIMATOLOGY WOULD SUGGEST THE FRONT NEVER GETS THIS FAR SE...SO THIS REMAINS TO BE SEEN. RAIN CHANCES WILL BE IN THE ISOLATED TO SCATTERED RANGE OVER THE WEEKEND...THEN WE PREFER NOTHING MORE THAN ISOLATED COVERAGE MONDAY AND TUESDAY SINCE OUR CONFIDENCE LOWERS. TEMPS WILL REMAIN ABOVE SEASONAL LEVELS SATURDAY AND SUNDAY...TRENDING BACK CLOSER TO NORMAL MONDAY AND TUESDAY. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... WE HAVE MAINTAINED PREVAILING VFR CONDITIONS THROUGH 18Z WEDNESDAY. HOWEVER...THERE ARE INDICATIONS THAT AN MCS COULD IMPACT THE AREA EARLY TONIGHT. PROSPECTS FOR THIS TO OCCUR ARE GREATER AT KCHS THAN AT KSAV BUT ARE STILL PRETTY LOW SO WILL MAINTAIN PROB30 ...THUS OUR INCLUSION OF A PROB30 FOR TSRA AT KCHS FROM 01-05Z. IF ORGANIZED TSRA DOES DEVELOP...THEN STRONG WINDS ARE POSSIBLE...WITH PERIODIC MVFR OR LOWER CONDITIONS TO OCCUR. EXTENDED AVIATION OUTLOOK...DIURNAL SHOWERS AND THUNDERSTORMS POSSIBLE THROUGH THE WEEK. && .MARINE... THE LOCAL WATERS WILL CONTINUE TO BE POSITIONED IN AN AREA BETWEEN THE INLAND TROF TO THE WEST AND THE SUBTROPICAL HIGH OVER THE OPEN ATLANTIC. THIS WILL MAINTAIN THE RELATIVELY TIGHT PRESSURE GRADIENT AND KEEP THE LOW LEVEL SW FLOW ELEVATED. WINDS WILL RANGE BETWEEN 15-20 KNOTS...ESPECIALLY OVER THE SC WATERS THROUGH TONIGHT. THERE MAY BE AN OCCASIONAL GUST TO AROUND 25 KNOTS LATE TONIGHT...BUT LIKELY NOT FREQUENT ENOUGH TO WARRANT A SCA AT THIS POINT. SEAS WILL RUN 2-4 FT WITHIN 20 NM...AND 4-5 FEET BEYOND. THUNDERSTORMS MAY MOVE INTO PORTIONS OF THE WATERS...INCLUDING THE CHARLESTON HARBOR TONIGHT. SOME OF THESE STORMS WILL BE STRONG OR EVEN SEVERE...WITH POSSIBLE DAMAGING WINDS...FREQUENT LIGHTNING AND REDUCED VISIBILITY IN HEAVY RAINS. WEDNESDAY THROUGH SUNDAY...A WEAKER PRESSURE PATTERN WILL TEMPORARILY SET UP ACROSS THE COASTAL WATERS ON WEDNESDAY...AS THE INLAND TROUGH DIMINISHES IN STRENGTH. BUT THIS WILL BE SHORT-LIVED...AS THE INLAND TROUGH ONCE AGAIN BECOMES BETTER DEFINED FOR THE REMAINDER OF THE WEEK. WITH THE NORTH ATLANTIC SUBTROPICAL HIGH SUPPRESSED TO THE SOUTH ACROSS SOUTHERN FL...THERE IS ENOUGH OF A GRADIENT TO GENERATE MOSTLY MODERATE TO PERHAPS OCCASIONAL FRESH SOUTHWESTERLY BREEZES ACROSS THE MARINE COMMUNITY. SEAS WILL BE A MIXTURE OF SHORT PERIOD WIND DRIVEN WAVES AND LONGER PERIOD SWELL WAVES...WITH THE RESULTING COMBINED SEAS MOSTLY HELD AT OR BELOW 4 OR 5 FT. RIP CURRENTS...THERE WILL BE A MODERATE RISK FOR RIP CURRENTS AT THE SOUTH CAROLINA BEACHES TODAY DUE TO LINGERING SWELLS AND BREEZY CONDITIONS. && .EQUIPMENT...
