AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 611 PM EDT SAT JUN 26 2010 .SYNOPSIS... HIGH PRESSURE WILL SLOWLY WEAKEN ACROSS THE AREA THROUGH TUESDAY BEFORE A COLD FRONT DROPS INTO THE SOUTHEAST UNITED STATES WEDNESDAY THROUGH FRIDAY. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... WHERE THE SEA BREEZE INTERACTS WITH ONGOING THUNDERSTORMS/ ASSOCIATED OUTFLOW BOUNDARIES ACROSS INTERIOR SE GA...SCATTERED TO NUMEROUS SHOWERS/THUNDERSTORMS WILL DEVELOP THROUGH EARLY EVENING...ACCOMPANIED BY GUSTY WINDS/LOCALLY HEAVY RAINFALL AND A LOW CHANCE FOR A DAMAGING WET MICROBURST OR TWO. ELSEWHERE ISOLATED SHOWERS/THUNDERSTORMS WILL DEVELOP ALONG THE INLAND ADVANCING SEA BREEZE. WILL MONITOR INLAND CONVECTIVE TRENDS...AS OUTFLOW FROM MIDLANDS THUNDERSTORMS COULD PUSH INTO INLAND COUNTIES TO PRODUCE NEW THUNDERSTORMS DURING THE SUNSET TO MIDNIGHT TIME PERIOD. EXPECT MUCH OF THE CONVECTION TO DIMINISH OVERNIGHT...POSSIBLY SHIFTING INTO THE ATLC AS A WEAK MID-LEVEL SHORTWAVE PUSHES OFFSHORE. IT WILL BE ANOTHER WARM AND MUGGY NIGHT WITH LOWS IN THE LOWER-MID 70S WITH UPPER 70S/LOWER 80S AT THE COAST. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/... THE PATTERN WILL SLOWLY BECOME MORE CONVOLUTED SUNDAY THROUGH TUESDAY AS THE UPPER RIDGE WEAKENS AND UPPER-LEVEL FLOW BEGINS TO BACK. DECREASING UPPER HEIGHTS WILL LOWER CONVECTIVE TEMPERATURES INTO THE UPPER 80S...ALLOWING CONVECTION TO BEGIN FIRING BY LATE SUNDAY MORNING. APPROACHING SHORTWAVE ENERGY FROM SOUTH CENTRAL GA MAY INCREASE COVERAGE IN SOUTHEAST GEORGIA DURING THE AFTERNOON... THEREFORE WE HAVE THE SLIGHTLY HIGHER POPS IN THAT AREA. THE WESTERLY FLOW JUST OFF THE SURFACE LOOKS TO SUBSIDE BY SUNDAY MORNING WHICH SHOULD ALLOW THE SEABREEZE TO MOVE INLAND EARLIER IN THE DAY. THIS SHOULD ALSO ACT AS A TRIGGER FOR SHOWERS AND TSTMS. TEMPERATURE FORECAST FOR SUNDAY IS QUITE TRICKY DUE TO THE UNCERTAINTIES IN CLOUD COVER. WE MAY SEE CONSIDERABLE MID-LEVEL CLOUDINESS MOVING IN DURING THE MORNING SIMILAR TO TODAY WHICH WILL HOLD TEMPS BACK. WE LEANED TOWARD THE COOLER NAM GUIDANCE FOR SUNDAY HIGHS...GENERALLY FEATURING LOWER TO MIDDLE 90S. HEAT INDICES COULD BRIEFLY REACH 105 DURING THE MID AFTERNOON BUT THERE ARE MANY NEGATING FACTORS WITH REGARD TO THE POSSIBLE NEED FOR A HEAT ADVISORY. A PLETHORA OF WEAK SHORTWAVES WILL MOVE ACROSS THE AREA MONDAY THROUGH TUESDAY WHILE PRECIPITABLE WATER VALUES REMAIN WELL ABOVE TWO INCHES. DEPENDING ON HOW MUCH MID AND HIGH LEVEL CLOUDINESS IS IN PLACE DURING THE TIMES OF MAXIMUM HEATING...SURFACE-BASED INSTABILITY COULD BE THE MAIN PLAYER IN HOW STRONG/ORGANIZED CONVECTION CAN BECOME. THE BRUNT OF THE ACTIVITY WILL OCCUR DURING THE DAY BUT ENOUGH FORCING MAY ALLOW SOME SHOWERS/TSTMS TO CONTINUE OVERNIGHT IN SOME AREAS. WILL MAINTAIN SOLID CHANCE POPS BOTH DAYS WITH SLIGHT CHANCE POPS OVERNIGHT. TEMPS WILL BE A DEGREE OR TWO COOLER IN RESPONSE TO LOWER THICKNESSES AND MORE CLOUDINESS. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... EXTENDED FORECAST CONTINUES TO BE TRICKY...AS THE LATEST GFS SOLUTION REMAINS RATHER AGGRESSIVE WITH SHORTWAVE ACTIVITY ALONG THE SOUTHERN END OF THE UPPER TROUGH MID TO LATE WEEK. HAVE OPTED TO INCORPORATE HPC GUIDANCE INTO THE FORECAST FOR THE WEDNESDAY AND THURSDAY TIME FRAME...AS IT REPRESENTS A DECENT BLEND BETWEEN PERSISTENCE AND SOME ENSEMBLE MODEL SOLUTIONS. ALTHOUGH DETAILS ARE UNCERTAIN CONSIDERING MODEL DISAGREEMENT...IT APPEARS QUITE POSSIBLE THAT THE COLD FRONT WILL BE ABLE TO SLIP THROUGH THE FORECAST AREA MID WEEK...RESULTING IN NORTHEAST SURFACE FLOW AND LOWER DEWPOINTS BY THURSDAY AND FRIDAY. HAVE LOWERED SHOWER/THUNDERSTORM CHANCES LATE WEEK...AS DEEP MOISTURE WILL SHIFT SOUTHEAST OF THE REGION WITH FRONTAL PROGRESSION. && .AVIATION /22Z SATURDAY THROUGH THURSDAY/... THUNDERSTORMS ARE MOST LIKELY TO IMPACT KSAV BEFORE 00Z...THUS EXPECT AMENDMENTS FOR THIS SITE. MAINTAINED A MENTION OF CBS AT KCHS THROUGH EARLY EVENING...BUT THE PROBABILITY OF DIRECT IMPACT AT THIS SITE IS DIMINISHING WITH TIME. PATCHY FOG DEVELOPMENT EARLY SUNDAY MORNING WILL DEPEND ON RAINFALL AT/CLOSE TO TERMINALS. THE POTENTIAL FOR SUB-VFR CONDITIONS REMAINS TOO LOW TO INCLUDE IN TAFS. EXTENDED AVIATION OUTLOOK...BRIEF PERIODS OF MVFR OR IFR CEILINGS AND/OR VISIBILITIES ARE POSSIBLE DURING AFTERNOON/EVENING THUNDERSTORMS. && .MARINE... TONIGHT...S/SW WIND REGIME WILL DOMINATE WITH SUBTROPICAL HIGH PRESSURE CENTERED WELL OFFSHORE. WILL SEE SOME ENHANCEMENT ALONG THE LAND/SEA INTERFACE AND CHARLESTON HARBOR INTO EARLY EVENING AS THE SEA BREEZE PUSHES INLAND...BUT NO FLAGS ARE ANTICIPATED. THE PATTERN FAVORS ANOTHER NOCTURNAL SURGE TONIGHT ACROSS THE WATERS. SPEEDS AS HIGH AS 15-20 KT ARE EXPECTED WITH SPEEDS DIMINISHING EARLY SUNDAY MORNING. SEAS OF 2-4 FT WILL PERSIST THROUGH THE PERIOD WITH A NOTICEABLE 2-3 FT/8 SEC SE SWELL. SUNDAY THROUGH THURSDAY...ATLANTIC HIGH PRESSURE WILL PREVAIL THROUGH THE PERIOD...WITH A COLD FRONT SLOWLY APPROACHING FROM THE NORTHWEST. WINDS WILL REMAIN FROM THE SOUTH OR SOUTHWEST THROUGH TUESDAY...POSSIBLY TRANSITIONING TO THE NORTHEAST AS EARLY AS WEDNESDAY DEPENDING ON THE SPEED OF THE COLD FRONT. WIND SPEEDS COULD POTENTIALLY REACH AS HIGH AS 15-20 KT AT TIMES OVER PORTIONS OF THE MARINE AREA DUE TO THE INFLUENCE OF THE AFTERNOON SEA BREEZE AND NOCTURNAL SURGING. HOWEVER...CONDITIONS ARE EXPECTED TO REMAIN BELOW SMALL CRAFT ADVISORY CRITERIA THROUGH THE FORECAST PERIOD. RIP CURRENTS...SE SWELL EVERY 8 SECONDS COMBINED WITH ADDED INFLUENCES FROM TODAY/S FULL MOON WILL SUPPORT A MODERATE RISK FOR RIP CURRENTS AT THE SC BEACHES SUNDAY. && .CHS WATCHES/WARNINGS/ADVISORIES...
