NWS Charleston, SC wrote its last area forecast discussion before the first event at Jun 5, 2:41 PM EST, 1 hour earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 341 PM EDT THU JUN 5 2014 .SYNOPSIS... A BACKDOOR COLD FRONT WILL APPROACH FROM THE NORTH TONIGHT...THEN BECOME NEARLY STATIONARY OVER THE REGION FRIDAY AND SATURDAY. THE FRONT WILL GRADUALLY DISSIPATE BY SUNDAY. ANOTHER COLD FRONT WILL SLOWLY APPROACH FROM THE NORTHWEST THROUGH THE MIDDLE OF NEXT WEEK. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... REST OF THIS AFTERNOON AND TONIGHT...CONVECTION HAS NOW INITIATED TO THE WEST IN THE VICINITY OF AUGUSTA AND WELL TO THE NORTH ALONG AND NORTH OF THE NORTH CAROLINA/SOUTH CAROLINA STATE LINE. IT APPEARS THEN THAT OUR BEST BET FOR CONVECTIVE COVERAGE WILL BE WITH THE DEVELOPMENT TO THE WEST AND ITS EVOLUTION TO THE EAST. THE THERMODYNAMIC ENVIRONMENT REMAINS SUPPORTIVE OF A FEW SEVERE THUNDERSTORMS. CAPE VALUES ARE IN EXCESS OF 2500 J/KG AND THERE IS A NOTABLE POCKET OF DCAPES HIGHER THAN 1000 J/KG SPREADING INTO THE REGION. WHILE IT WOULD NOT BE OUT OF THE QUESTION TO SEE SOME LARGE HAIL...DAMAGING WIND GUSTS REMAIN THE PRIMARY SEVERE THREAT. WILL EXPAND THE SEVERE THUNDERSTORM MENTION IN THE HWO TO INCLUDE ALL OF THE FORECAST AREA. THE SPREAD OF CONVECTION AND POPS WILL LARGELY BE DRIVEN BY OUTFLOW BOUNDARIES SPAWNING NEW SHOWERS AND STORMS. THE SEVERE THREAT WILL LIKELY LINGER INTO THE LATE EVENING DEPENDING ON HOW MESOSCALE BOUNDARIES DEVELOP AND INTERACT. POPS WILL CERTAINLY DECREASE INTO THE OVERNIGHT...BUT WITH THE FRONT DRAWING CLOSER FROM THE NORTH AND SHORTWAVE ENERGY MOVING IN FROM THE NORTHWEST THERE IS CERTAINLY A CHANCE FOR ADDITIONAL DEVELOPMENT INTO FRIDAY MORNING. AS SUCH A SLIGHT CHANCE IS MAINTAINED THROUGH THE EARLY FRIDAY MORNING HOURS. OVERNIGHT LOWS WILL BE QUITE MILD ONLY FALLING INTO THE LOW TO MID 70S. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/... A RATHER UNSETTLED PATTERN EXPECTED THIS PERIOD AS A BACKDOOR COLD FRONT STALLS OUT OVER OR NEAR THE AREA. PWATS NEAR 1.75 INCHES ALONG WITH SHORTWAVE ENERGY SHOULD BE SUFFICIENT FOR SCATTERED CONVECTION...MOSTLY DURING THE DAYTIME/EVENING WHEN MODEST INSTABILITY IS EXPECTED. BULK SHEAR VALUES ARE MOSTLY 20 KT OR LESS SO THE CONVECTION SHOULD NOT BE WELL ORGANIZED...THUS LIMITING THE OVERALL SEVERE THREAT...ALTHOUGH ISOLATED SEVERE STORMS ARE CERTAINLY POSSIBLE EACH DAY MAINLY WHERE MESOSCALE BOUNDARY INTERACTIONS OCCUR AND ENHANCE UPDRAFT STRENGTH. THERE WILL LIKELY BE THE GREATEST INSTABILITY ON FRIDAY AND THUS THIS MAY BE THE DAY WITH THE BEST CHANCE FOR SEVERE STORMS. THE TEMPS SHOULD BE SLIGHTLY ABOVE NORMAL...MAXING OUT NEAR 90 IN THE AFTERNOON AND BOTTOMING OUT NEAR 70 AT NIGHT. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... THE PATTERN AT THE SURFACE AND ALOFT WILL BE TRANSITIONING ON MONDAY...BEFORE POTENTIALLY BECOMING MORE AMPLIFIED TUESDAY INTO THE MID WEEK PERIOD. THERE ARE SOME RATHER NOTABLE DISCREPANCIES IN PATTERN EVOLUTION AND TIMING BETWEEN MEDIUM RANGE MODELS REGARDING AN APPROACHING UPPER LEVEL TROUGH...EMBEDDED SHORTWAVE ENERGY AND A SURFACE COLD FRONT TO THE WEST. THESE DIFFERENCES AFFECT SENSIBLE WEATHER IMPACTS...WITH SLOWER SOLUTIONS SUGGESTING LESS THUNDERSTORM COVERAGE EARLY IN THE WEEK. DUE TO THE UNCERTAINTY IN FORECAST DETAILS...PREFER TO LEAN TOWARD CLIMATOLOGY AND INDICATE SCATTERED THUNDERSTORM DEVELOPMENT EACH AFTERNOON/EARLY EVENING ALONG/INLAND OF THE SEABREEZE...WITH COVERAGE DIMINISHING EACH NIGHT. AS MODEL SOLUTIONS COME INTO BETTER AGREEMENT...MORE DETAIL CAN BE ADDED TO DISTINGUISH POTENTIAL AND COVERAGE ACROSS THE FORECAST AREA. TEMPERATURES ARE EXPECTED TO AVERAGE A FEW DEGREES ABOVE SEASONAL NORMALS EACH DAY...WITH HIGHS REACHING THE UPPER 80S TO LOWER 90S AWAY FROM THE LOCALLY COOLER COASTLINE. && .AVIATION /20Z THURSDAY THROUGH TUESDAY/... VFR CONDITIONS WILL PREVAIL THROUGH 18Z FRIDAY. THE BIGGEST NEAR TERM CONCERN IS THE POTENTIAL FOR CONVECTIVE DEVELOPMENT NEAR THE TERMINALS LATE THIS AFTERNOON AND EVENING. SO FAR...NO DEVELOPMENT IS OCCURRING NEARBY. THE CURRENT FORECAST THINKING IS THAT CONVECTION CURRENTLY DEVELOPING NORTH OF THE AREA ALONG THE NORTH CAROLINA/SOUTH CAROLINA STATE LINE WILL DRIFT SOUTHWARD AND INITIATE MORE CONVECTION FURTHER SOUTH IN THE MID/LATE AFTERNOON. THEREFORE...KCHS IS THE TERMINAL THAT HAS THE HIGHEST CHANCE OF DIRECT IMPACTS FROM THUNDERSTORMS. I HAVE ADDED A TEMPO FOR MVFR THUNDER WITH GUSTY WINDS BETWEEN 21-23Z. CONFIDENCE IS LOWER AT KSAV AS IT DEPENDS ON HOW UPSTREAM CONVECTION EVOLVES. FOR NOW...I HAVE ADJUSTED THE TIMING OF THE VCTS...AND AMENDMENTS TO ADD THUNDER MAY BE NECESSARY. OVERNIGHT...THERE MAY BE ADDITIONAL SHOWERS AND THUNDERSTORMS BUT THE PROBABILITY IS TOO LOW TO MENTION AT THIS TIME. WINDS WILL TURN MORE NORTH OR NORTHWEST LATE TONIGHT AND INTO FRIDAY MORNING AS THE COLD FRONT GETS INTO THE REGION. EXTENDED AVIATION OUTLOOK...CHANCES FOR BRIEF FLIGHT RESTRICTIONS IN MAINLY AFTERNOON/EVENING CONVECTION FRIDAY THROUGH SUNDAY. OTHERWISE...MOSTLY VFR. && .MARINE... TONIGHT...THE MODESTLY TIGHT PRESSURE GRADIENT IN PLACE RIGHT NOW WILL GRADUALLY RELAX THROUGH THE NIGHT AS THE COLD FRONT APPROACHES FROM THE NORTH AND A WEAK AREA OF LOW PRESSURE ALONG IT DRAWS CLOSER. WINDS WILL BE STRONGEST EARLY IN THE EVENING...MAINLY IN THE 15-20 KT RANGE. THEN CLOSER TO DAY BREAK WINDS WILL DROP OFF TO BE 15 KT OR LESS AND WILL VEER AROUND TO BECOME SLIGHTLY MORE WESTERLY WITH TIME. SEAS WILL BE 2-3 FT WITHIN 20 NM...EXCEPT UP TO 4 FT AROUND 20 NM FOR THE CHARLESTON COUNTY WATERS...AND 3-4 FT BEYOND 20 NM. THUNDERSTORMS MAY MOVE INTO THE WATERS FROM LAND AREAS AND COULD PRODUCE GUSTY WINDS THIS EVENING AND INTO THE EARLY MORNING HOURS. FRIDAY THROUGH TUESDAY...A WEAK TROUGH OF LOW PRESSURE WILL MEANDER ACROSS THE WATERS THROUGH AT LEAST SATURDAY...SUPPORTING A WEAK PRESSURE GRADIENT AND GENERALLY LIGHT/VARIABLE WINDS. THE TROUGH WILL SHIFT INLAND EARLY NEXT WEEK WITH MORE OF TYPICAL SUMMER PATTERN EXPECTED. WINDS AND SEAS ARE EXPECTED TO REMAIN WELL BELOW ADVISORY CRITERIA THROUGH THE PERIOD. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE.
