NWS Charleston, SC wrote its last area forecast discussion before the first event at May 28, 2:39 PM EST, 2 hours 36 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 339 PM EDT WED MAY 28 2014 .SYNOPSIS... ATLANTIC HIGH PRESSURE WILL REMAIN IN PLACE TONIGHT. A WEAK BACKDOOR COLD FRONT IS EXPECTED TO APPROACH THE AREA FROM THE NORTH THURSDAY BEFORE PUSHING SOUTH OF THE AREA BY SUNDAY. STRONGER HIGH PRESSURE WILL THEN BUILD FROM THE NORTH EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... REST OF THE AFTERNOON...SO FAR THE BULK OF THE SHOWER/THUNDERSTORM DEVELOPMENT HAS REMAINED CONFINED TO SOUTHEAST GEORGIA AWAY FROM THE IMMEDIATE COASTLINE. STORMS HAVE BEEN RELATIVELY SHORT-LIVED AS UPDRAFTS APPEAR TO BE STRUGGLING TO MAINTAIN GIVEN THE LESS THAN IMPRESSIVE MID-LEVEL ENVIRONMENT. THE SPC MESOANALYSIS PAGE SHOWS THE BEST INSTABILITY ALONG AND WEST OF THE SAVANNAH RIVER SO POPS HAVE BEEN FAVORED THERE. THE SEVERE THREAT REMAINS QUITE LOW...BUT THE CHANCE REMAINS FOR AN ISOLATED SEVERE STORM WHERE MORE SIGNIFICANT BOUNDARY INTERACTIONS OCCUR. TONIGHT...ALOFT THE UPPER RIDGE AXIS WILL REMAIN IN PLACE AS THE OVERALL PATTERN REMAINS UNCHANGED. ATLANTIC HIGH PRESSURE WILL CONTINUE TO EXTEND WESTWARD AND ACROSS THE FORECAST AREA WITH A PREVAILING SOUTHWEST FLOW. ANY LINGERING EVENING SHOWER/THUNDERSTORM ACTIVITY WILL DIMINISH QUICKLY WITH SUNSET...AND THE REST OF THE OVERNIGHT IS EXPECTED TO REMAIN DRY. ANY LINGERING DEBRIS CLOUDS SHOULD THIN AND CLEAR OUT THROUGH THE NIGHT...WITH SKIES BECOMING MOSTLY CLEAR BY SUNRISE. ANOTHER MILD NIGHT IS ON TAP WITH LOWS FALLING TO AROUND 70 IN MOST AREAS. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/... ATLANTIC HIGH PRESSURE WILL SLOWLY WEAKEN OFFSHORE THIS PERIOD WHILE A BACKDOOR COLD FRONT SLOWLY SINKS SOUTHWARD INTO THE AREA FRIDAY. WARM AND HUMID CONDITIONS...MORE TYPICAL OF SUMMER...WILL PREVAIL WITH MOSTLY AFTERNOON AND EARLY EVENING SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THURSDAY. BY FRIDAY COVERAGE OF RAIN SHOULD BE A BIT GREATER GIVEN THE ADDED CONVERGENCE WITH THE FRONT...ALTHOUGH THERE WILL BE A BIT GREATER MID-LEVEL CAPPING WHICH SHOULD TEMPER COVERAGE A BIT. GIVEN THE LACK OF STRONG SYNOPTIC FORCING THE RISK FOR ANY SEVERE STORMS WILL REMAIN LOW. TEMPS GENERALLY SLIGHTLY ABOVE NORMAL THROUGH THE PERIOD. && .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 /20Z 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 THURSDAY THROUGH SATURDAY. BEST CHANCES SHOULD BE FRIDAY AS A WEAK BACKDOOR FRONT SLOWLY MOVES THROUGH. BREEZY CONDITIONS LIKELY SUNDAY. && .MARINE... TONIGHT...SUBTROPICAL HIGH PRESSURE OVER THE ATLANTIC WILL CONTINUE TO BE THE PRIMARY SURFACE FEATURE AS IT EXTENDS WESTWARD ACROSS THE LOCAL WATERS. THE HIGH WILL MAINTAIN A MODEST SOUTH TO SOUTHWEST FLOW WHICH WILL GENERALLY BE 15 KT OR LESS THROUGH THE PERIOD. SEAS WILL BE 2-3 FT. WEDNESDAY THROUGH SUNDAY...NO SIGNIFICANT CONCERNS GIVEN THE RELATIVELY WEAK PRESSURE GRADIENT OVER THE AREA BETWEEN ATLANTIC HIGH PRESSURE AND AN INLAND TROUGH. BY FRIDAY THE TROUGH SHOULD SINK SOUTHWARD INTO THE LOCAL WATERS...LIKELY PUSHING SOUTH OF THE GEORGIA WATERS BY SUNDAY. AFTER THE FROPA...THE GRADIENT WILL INCREASE POSSIBLY LEADING TO MARGINAL ADVISORY CONDITIONS EARLY NEXT WEEK...ESPECIALLY BEYOND 20 NM. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. && NEAR TERM...BSH SHORT TERM...RJB LONG TERM...RFM AVIATION...BSH MARINE...BSH/RJB
