NWS Charleston, SC wrote its last area forecast discussion before the first event at May 28, 1:16 PM EST, 1 hour 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 216 PM EDT WED MAY 28 2014 .SYNOPSIS... ATLANTIC HIGH PRESSURE WILL EXTEND ACROSS THE REGION TODAY. A WEAK BACKDOOR COLD FRONT IS EXPECTED TO APPROACH THE AREA FROM THE NORTH THURSDAY...THEN WEAKEN AND SLOWLY MOVE SOUTHWARD THROUGH THE AREA INTO SATURDAY. STRONGER HIGH PRESSURE WILL BUILD FROM THE NORTH LATER SATURDAY AND SUNDAY...PERSISTING INTO EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... EARLY THIS AFTERNOON...CONVECTION HAS INITIATED OVER INLAND SOUTHEAST GEORGIA PRIMARILY. OVERALL THE FORECAST REMAINS ON TRACK AND NO SIGNIFICANT ADJUSTMENTS WERE NEEDED. PREVIOUS DISCUSSION FOLLOWS BELOW. LATE THIS MORNING...REGIONAL RADAR IMAGERY SHOWS THAT ANY EARLIER SHOWER ACTIVITY ACROSS THE MIDLANDS HAS DIMINISHED AND ALL THAT IS LEFT OVER IS AN AREA OF CLOUDINESS TO THE NORTH. THE OVERALL SETUP TODAY IS QUITE SIMILAR TO TUESDAY. THE RIDGE DOWNSTREAM OF THE UPPER LOW OVER THE ARKLATEX REGION REMAINS IN PLACE WITH NO SIGNIFICANT FORCING NOTED. THERE IS A VERY SUBTLE SHORTWAVE AND ASSOCIATED VORT MAX MOVING ACROSS THE CENTRAL GEORGIA/SOUTH CAROLINA REGION...AND THAT MAY HELP TO INITIATE CONVECTION LATER ON THIS AFTERNOON. CONVECTIVE COVERAGE WILL PRIMARILY BE FORCED BY DIFFERENTIAL HEATING AND WEAK CONVERGENCE ALONG THE AFTERNOON SEA BREEZE. NO SIGNIFICANT CHANGES WERE MADE TO THE PREVIOUS FORECAST...AND CONVECTIVE INITIATION IS EXPECTED TO BEGIN IN THE VERY EARLY AFTERNOON HOURS. THE EVENTUAL EVOLUTION OF SHOWERS AND STORMS WILL BE DRIVEN BY MESOSCALE BOUNDARIES AND BOUNDARY INTERACTIONS. THE OVERALL SEVERE THREAT REMAINS LOW WITHIN A WEAKLY FORCED/SHEARED ENVIRONMENT. A MODIFIED 12Z KCHS SOUNDING RESULTS IN AROUND 2500 J/KG OF CAPE WITH MARGINAL MID LEVEL LAPSE RATES AND OTHER INDICES. WE CANNOT COMPLETELY RULE OUT A ONE OR TWO STRONG TO SEVERE STORMS...BUT NOTHING ORGANIZED IS EXPECTED. STORM MOTIONS WILL BE LESS THAN 10 KTS SO PERHAPS THE BIGGER CONCERN WILL BE LOCALLY HEAVY RAINFALL. TEMPERATURES WILL BE QUITE SIMILAR TO TUESDAY...AND THE FORECAST FEATURES UPPER 80S TO 90 IN MOST AREAS AWAY FROM THE IMMEDIATE COAST. && .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/... TONIGHT...SHOWERS/TSTMS WILL GRADUALLY DISSIPATE THIS EVENING WITH THE LOSS OF INSOLATION. DEBRIS CLOUDINESS WILL ALSO GRADUALLY WANE WITH SKIES LIKELY BECOMING PARTLY CLOUDY OR EVEN MOSTLY CLEAR EARLY THURSDAY MORNING. LOWS WILL RANGE FROM THE UPPER 60S INLAND TO THE LOWER-MID 70S AT THE COAST. INCREASING DEEP LAYER MOISTURE AND CHANCES FOR RAINFALL EXPECTED THROUGH MUCH OF THIS PERIOD. TEMPERATURES NEAR TO SLIGHTLY ABOVE NORMAL. THURSDAY...AN ATLANTIC RIDGE SOUTHEAST OF THE REGION WILL CONTINUE TO WEAKEN AND PUSH SOUTHWARD. AT UPPER LEVELS...THE FORECAST AREA WILL BE IN A COL/LIGHT FLOW REGION...BETWEEN A WEAKENING UPPER LOW OVER THE SOUTHERN GULF STATES AND A TROUGH OVER THE NORTHEAST STATES. AT LOWER LEVELS...LIGHT SOUTHWEST FLOW WILL BECOME ONSHORE DURING THE AFTERNOON. EXPECT SCATTERED SHOWERS AND THUNDERSTORMS TO DEVELOP BY AFTERNOON. DUE TO RELATIVELY SLOW STEERING...LOCALLY HEAVY RAINFALL POSSIBLE. MODELS INDICATING MODERATE INSTABILITY... ESPECIALLY INLAND. HOWEVER...LACK OF UPPER SUPPORT AND WEAK BOUNDARY INTERACTION SHOULD GREATLY REDUCE CHANCES FOR ANY ISOLATED STRONG/SEVERE STORMS. FRIDAY...THE WEAK BACKDOOR FRONT THAT HAS BEEN ADVERTISED FOR DAYS SEEMS TO GET SLOWER AND WEAKER WITH EACH RUN. LATEST RUNS PLACE THE SURFACE TROUGH ASSOCIATED WITH THIS FEATURE AT LEAST ACROSS THE NORTHERN FORECAST AREA BY AFTERNOON. LOW LEVEL CONVERGENCE BETWEEN THIS FRONT AND SEA BREEZE SHOULD HELP TO FOCUS SCATTERED TO POSSIBLY NUMEROUS MAINLY AFTERNOON SHOWERS/THUNDERSTORMS. THUS...EXPECT THIS PERIOD TO BE THE BEST CHANCES FOR CONVECTION/RAINFALL. HAVE NUDGED POPS UP A TAD...BUT STILL CONSERVATIVE. MAY NEED LIKELY TO CATEGORICAL POPS AT SOME POINT. AGAIN...LACK OF SIGNIFICANT UPPER SUPPORT SHOULD LIMIT POTENTIAL FOR ANY STRONG/SEVERE STORMS. CONVECTION COULD LINGER WELL INTO THE EVENING DUE TO THE FRONTAL TROUGH AND SUFFICIENT MOISTURE AND BOUNDARY INTERACTIONS. SATURDAY...A DEEP LAYER RIDGE BEGINS TO BUILD SOUTHWARD FROM THE NORTHWEST ALONG WITH A DIGGING UPPER TROUGH OFF THE MID ATLANTIC COAST. THIS HELPS TO DRIVE THE BEST DEEP LAYER MOISTURE A LITTLE FURTHER SOUTH DURING THE DAY...WITH THE HIGHEST POPS EXPECTED OVER THE SOUTHERN HALF OF THE AREA. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... MODELS IN GOOD AGREEMENT WITH THE LARGE SCALE PATTERN...SHOWING A BUILDING RIDGE FROM THE GREAT LAKES SOUTHWARD INTO THE SOUTHEAST U.S. THROUGH SUNDAY. THIS RIDGE FLATTENS AND MOVES OVER THE AREA MONDAY...THEN SOUTHEAST OF THE REGION TUESDAY AND WEDNESDAY. SATURDAY WILL BE THE TRANSITION DAY...WITH SCATTERED AFTERNOON CONVECTION...ESPECIALLY SOUTHERN 1/2 OF THE AREA. CONTINUED DRYING TREND FOR SUNDAY AND MONDAY AS THE RIDGE TO THE NORTH PUSHES DRIER/SUBSIDING AIR SOUTHWARD. HAVE KEPT SLIGHT CHANCE POPS EXTREME SOUTH SUNDAY...THEN LESS THEN 15% FOR MONDAY ALL AREAS. BY TUESDAY AND WEDNESDAY ...MODELS INDICATING SOME MOISTURE RETURN ON THE BACK/WEST SIDE OF THE RIDGE. THUS...HAVE GRADUALLY BROUGHT BACK LOW END CHANCE POPS TUESDAY AND WEDNESDAY FOR AFTERNOON CONVECTION. NEAR NORMAL TEMPERATURES SUNDAY AND MONDAY...CLIMBING TO SLIGHTLY ABOVE NORMAL TUESDAY AND WEDNESDAY AS THE RIDGE MOVES OVER THE AREA AND LOW LEVEL SOUTHWEST FLOW SETS IN. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... VFR CONDITIONS WILL PREVAIL THROUGH 18Z THURSDAY. THE BIGGEST NEAR TERM CONCERN IS THE POTENTIAL FOR IMPACTS FROM THUNDERSTORMS AT THE TERMINALS. BASED ON CURRENT RADAR IMAGERY...THE BEST COVERAGE IS ACROSS SOUTHEAST GEORGIA SO A VCTS HAS BEEN ADDED TO KSAV THROUGH 21Z. THE CHANCE EXISTS AT KCHS AS WELL...BUT GIVEN THE LACK OF COVERAGE IN SOUTHEAST SOUTH CAROLINA...NOTHING WILL BE INCLUDED AT THIS TIME. ANY SHOWERS AND STORMS THAT DO DEVELOP WILL DIMINISH THIS EVENING WITH THE LOSS OF HEATING. EXTENDED AVIATION OUTLOOK...TEMPORARY FLIGHT RESTRICTIONS POSSIBLE WITH MAINLY AFTERNOON/EARLY EVENING SHOWERS AND TSTMS WEDNESDAY THROUGH SATURDAY. BEST CHANCES SHOULD BE FRIDAY AS A WEAK BACKDOOR FRONT SLOWLY MOVES THROUGH. BREEZY CONDITIONS LIKELY SUNDAY. && .MARINE... THROUGH TONIGHT...SOUTHERLY FLOW REGIME WILL DOMINATE THROUGH TONIGHT AS THE REGION REMAINS POSITIONED ALONG THE WESTERN FLANKS OF THE BERMUDA-AZORES SUBTROPICAL HIGH. SOME WEAK SURGES ARE LIKELY...ONE WITH THE SEA BREEZE CIRCULATION ITSELF WITH A SECONDARY NOCTURNAL SURGE TONIGHT. WINDS LOOK TO GENERALLY REMAIN 15 KT OR LESS WITH SEAS 1-3 FT. NO SIGNIFICANT CONCERNS/HIGHLIGHTS EXPECTED THROUGH FRIDAY AS WEAK ATLANTIC HIGH PRESSURE HOLDS ON SOUTHEAST OF THE REGION. BY LATE FRIDAY AND SATURDAY...A BACKDOOR COLD FRONT ENTERS FROM THE NORTH...PUSHING SOUTH OF THE WATERS LATER SATURDAY NIGHT AND SUNDAY. INCREASING NORTHEAST WINDS AND SEAS BEHIND THE FRONT...WITH MARGINAL SCA CONDITIONS POSSIBLE SATURDAY NIGHT AND SUNDAY. DECREASING WINDS/SEAS SUNDAY NIGHT AND MONDAY AS A RIDGE OF HIGH PRESSURE SHIFTS WELL NORTH AND EAST OF THE WATERS. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. && NEAR TERM...BSH SHORT TERM...RFM LONG TERM...RFM AVIATION...BSH MARINE...RFM/ST
