AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 206 PM EDT WED JUN 11 2014 .SYNOPSIS... A TROUGH OF LOW PRESSURE WILL DEVELOP OVER THE SOUTHEAST STATES AND PERSIST THROUGH EARLY NEXT WEEK BEFORE HIGH PRESSURE REBUILDS OVER THE WESTERN ATLANTIC. && .NEAR TERM /THROUGH TONIGHT/... WATER VAPOR IMAGERY CLEARLY DEPICTS THE ABUNDANT ENERGY AND MOISTURE DOWNSTREAM OF A ROBUST UPPER TROUGH AXIS CURRENTLY STRETCHING ACROSS THE OHIO AND MISSISSIPPI VALLEYS. DEEP MOISTURE CONTINUES TO STREAM NORTHWARD FROM THE GULF OF MEXICO AND CARIBBEAN...SUPPORTING PERSISTENT CONVECTION ACROSS NORTHERN FLORIDA AND SOUTHERN GEORGIA DURING THE LATE MORNING/EARLY AFTERNOON TIME FRAME. THE WEAKENING UPPER RIDGE ACROSS THE EAST COAST SUGGESTS LESS SUBSIDENCE AND LOWERING HEIGHTS ALOFT...SUPPORTING BETTER CONVECTIVE COVERAGE TODAY AND PERHAPS SLIGHTLY LOWER TEMPERATURES. WILL LEAN TOWARD LOW LEVEL THICKNESS VALUES FOR HIGH TEMPERATURES TODAY...INDICATING LOWER 90S AWAY FROM THE LOCALLY COOLER COASTLINE. ANALYSIS OF HIGH RESOLUTION MODELS CONTINUES A PREFERENCE TOWARD THE NSSL WRF SOLUTION THAT HAS HAD DECENT VERIFICATION DURING THE PAST FEW DAYS. AS SUCH...LITTLE CHANGE WAS NEEDED TO THE ONGOING THUNDERSTORM FORECAST THROUGH THE AFTERNOON. ACTIVITY SOUTH OF THE ALTAMAHA RIVER HAS STEADILY SHIFTED NORTH INTO GEORGIA ZONES ALONG AND WEST OF INTERSTATE 95...WHILE A NORTH/SOUTH ORIENTED LINE HAS DEVELOPED WELL INLAND OF THE FORECAST AREA. AT THE SAME TIME...ISOLATED SHOWERS/THUNDERSTORMS HAVE INITIATED ALONG THE SEABREEZE JUST TO THE NORTH OF THE FORECAST AREA. THE SEABREEZE WILL STEADILY PUSH INTO INLAND SOUTH CAROLINA DURING THE NEXT FEW HOURS...POSSIBLY REDUCING THUNDERSTORM COVERAGE INITIALLY FOR THE CHARLESTON TRI COUNTY AND SOUTH CAROLINA COASTLINE. CONVECTIVE COVERAGE WILL IMPROVE FARTHER TO THE SOUTH...AS THE ACTIVITY PROGRESSING INTO THE REGION FROM FLORIDA LIKELY INTERACTS WITH SEABREEZE CONVECTION NEAR COASTAL GEORGIA AND INLAND SOUTH CAROLINA. ORGANIZATION AND COVERAGE OF THUNDERSTORMS WILL FURTHER IMPROVE BY LATE AFTERNOON...WITH RATHER STRONG FORCING FOR ASCENT EXPECTED ONCE THE REGION BECOMES LOCATED BENEATH THE RIGHT ENTRANCE REGION OF THE UPPER JET AND UPPER LEVEL DIVERGENCE INCREASES. IN ADDITION...MODELS DEPICT STRONGER SHORTWAVES ALONG THE EASTERN PERIPHERY OF THE TROUGH LIFTING NORTHEAST ACROSS THE AREA. MODIFICATION OF MODEL FORECAST SOUNDINGS FOR HIGH TEMPERATURES IN THE LOWER 90S AND DEWPOINTS AROUND 70 PRODUCE CAPE VALUES BETWEEN 2000 AND 3000 J/KG AND DOWNDRAFT CAPES OF 500 TO 1000 J/KG. ALTHOUGH DEEP LAYER SHEAR WILL BE LIMITED...THE COMBINATION OF THE ABOVE FACTORS AND FORCING FOR ASCENT WITH THE PASSING SHORT WAVE WILL RESULT IN ORGANIZATION OF THUNDERSTORMS WITH THE POTENTIAL FOR SOME TO BECOME STRONG OR SEVERE THIS AFTERNOON AND EVENING...ESPECIALLY ACROSS SOUTHEAST GEORGIA AND INLAND SOUTHEAST SOUTH CAROLINA. THE PRIMARY THREATS ARE DAMAGING WIND AND LARGE HAIL. IT SHOULD BE NOTED THAT FREQUENT TO EXCESSIVE LIGHTNING IS ALSO EXPECTED WITH MANY OF THE THUNDERSTORMS...SIMILAR TO THE PAST COUPLE OF DAYS. OVERNIGHT...THE BULK OF THE CONVECTION SHOULD COME TO AN END AS THE EVENING PROGRESSES...SO GENERALLY RAIN-FREE CONDITIONS ARE EXPECTED LATE TONIGHT. DEBRIS CLOUDINESS COULD LINGER...MAKING THE SKY COVER FORECAST RATHER UNCERTAIN. OVERALL...LOW TEMPERATURES ARE EXPECTED TO BE IN THE UPPER 60S TO LOWER 70S ACROSS MUCH OF THE AREA. && .SHORT TERM /THURSDAY THROUGH SATURDAY/... THURSDAY...THE UPPER TROUGH WILL BE CENTERED OVER OUR INLAND AREAS...RESULTING IN A VEERING WIND PROFILE IN THE LOW AND MID LEVELS. MODEL SOUNDINGS SHOW A MODEST 800 MB CAP DEVELOPING BY EARLY AFTERNOON...WHILE VEERING LOW-LEVEL FLOW MIXES SURFACE DEWPOINTS INTO THE MID/UPPER 60S INLAND DURING THE AFTERNOON. THE DEEP SW TO WSW FLOW IN LOW-LEVELS WILL KEEP THE SEA BREEZE PINNED NEAR THE COAST UNTIL MID AFTERNOON WHEN IT PUSHES INLAND. ONCE IT MOVES INLAND LATER IN THE AFTERNOON IT COULD SPUR SOME SHOWERS AND TSTMS. IT LOOKS AS THOUGH OUR BEST CHANCE FOR CONVECTION WILL BE DURING THE MID TO LATE AFTERNOON ONCE UPSTREAM SHORTWAVE ENERGY PUSHES EAST...POSSIBLY ACCOMPANIED BY A CLUSTER OF SHOWERS AND TSTMS. HIGH TEMPS WILL REACH CLOSE TO 90 DEGREES. FRIDAY...THE UPPER TROUGH WILL SHIFT OFFSHORE WITH SHORTWAVE RIDGING DURING THE AFTERNOON. MODEL TIME SECTIONS SHOW THE PROFILE FURTHER VEERING WITH FAIRLY DEEP WEST-SOUTHWEST FLOW DURING THE DAY. THE SEA BREEZE LOOKS LATE AND WEAK...REDUCING ITS AVAILABILITY FOR TRIGGERING CONVECTION. DEWPOINTS WILL LIKELY MIX OUT AGAIN DURING THE AFTERNOON. HOWEVER...THE MODELS STILL HANG ONTO A WEAK SURFACE TROUGH INLAND WHICH COULD ALLOW FOR ISOLATED TO SCATTERED AFTERNOON AND EVENING SHOWERS AND TSTMS...ESPECIALLY IF OUTFLOW BOUNDARIES BEGIN TO INTERACT. HIGHS WILL BE 87-91. SATURDAY...ANOTHER WEAK UPPER LOW APPROACHES FROM THE WEST WHILE A SURFACE TROUGH HANGS ON ACROSS INLAND AREAS. THE SEA BREEZE SHOULD DEVELOP A BIT EARLIER IN THE DAY ALTHOUGH THE GRADIENT DOES NOT LOOK TERRIBLY STRONG. SCATTERED SHOWERS AND TSTMS EXPECTED AGAIN... PRIMARILY INLAND FROM THE COAST AND LATER IN THE DAY IF UPSTREAM ACTIVITY BECOMES SOMEWHAT ORGANIZED AND SHIFTS SOUTHEAST. HIGHS WILL BE IN THE LOWER 90S. && .LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/... THE REMNANTS OF THE UPPER TROUGH WILL LIFT OUT OF THE AREA SATURDAY NIGHT AND SUNDAY...WITH UPPER RIDGING DURING THE EARLY TO MIDDLE PART OF NEXT WEEK. THE INFLUENCE OF THE UPPER TROUGH ON SUNDAY COULD ALLOW FOR SLIGHTLY BETTER DAYTIME CONVECTIVE COVERAGE BEFORE WE RETURN TO A MORE ISOLATED SHOWER/TSTM PATTERN MONDAY THROUGH WEDNESDAY. HIGHS WILL BE IN THE LOWER 90S AND LOWS IN THE LOWER 70S. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... THUNDERSTORM ACTIVITY IS SPREADING INTO SOUTHEAST GEORGIA BY EARLY AFTERNOON AND EXPECT COVERAGE TO INCREASE OVERALL DURING THE NEXT SEVERAL HOURS. HOWEVER...UNCERTAINTY IN THE DETAILS OF COVERAGE TRENDS SUGGESTS KEEPING A MAINLY PERSISTENCE FORECAST FOR THE 18Z TAF ISSUANCE...INDICATING VCTS AT BOTH TERMINALS UNTIL EARLY EVENING. WILL INDICATE MORE CONFIDENCE OF THUNDERSTORM IMPACTS AT KSAV BY INCLUDING A TEMPO GROUP FOR TSRA AND MVFR VSBYS FROM 18Z TO 22Z. PREFER TO WAIT UNTIL TRENDS BECOME MORE CLEAR BEFORE ADDING SPECIFIC MENTION OF TSRA TO THE KCHS FORECAST...ESPECIALLY SINCE SEABREEZE CONVECTION COULD BE DELAYED UNTIL THE BOUNDARY IS WEST OF THE TERMINAL. TEMPORARY REDUCTIONS IN CEILINGS/VISIBILITIES AND ERRATIC/GUSTY WINDS ARE POSSIBLE WITH ANY THUNDERSTORMS...AS IS EXCESSIVE LIGHTNING. SHOWER/THUNDERSTORM POTENTIAL IS EXPECTED TO DECREASE DURING THE EVENING AND OVERNIGHT HOURS. EXTENDED AVIATION OUTLOOK...MODERATE RISK FOR BRIEF FLIGHT RESTRICTIONS AT EITHER TERMINAL EACH AFTERNOON/EARLY EVE DUE TO SHOWERS/THUNDERSTORMS. && .MARINE... TODAY AND TONIGHT...HIGH PRESSURE WELL OUT IN THE ATLANTIC WILL MAINTAIN A SOUTH TO SOUTHWEST FLOW ACROSS THE WATERS. SOME ENHANCEMENT IS EXPECTED ALONG THE LAND-SEA INTERFACE THIS AFTERNOON AND EVENING WITH THE SEA BREEZE...BUT OVERALL WINDS WILL REMAIN 15 KT OR LESS. SEAS WILL RANGE FROM 2-3 FT...HIGHEST ACROSS THE OUTER GA WATERS. THURSDAY THROUGH MONDAY...ATLANTIC HIGH PRESSURE WILL REMAIN THE DOMINANT FEATURE. SOUTH TO SOUTHWEST FLOW WILL PREVAIL...WITH MODEST AFTERNOON SEA BREEZE CIRCULATIONS DEVELOPING ALONG THE COAST. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE.
