The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Charleston, SC wrote its last area forecast discussion before the first event at May 23, 7:06 PM EST, 1 hour 10 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 806 PM EDT SUN MAY 23 2010 .SYNOPSIS... A HIGH PRESSURE WEDGE WILL PERSIST INLAND MONDAY AND TUESDAY. LOW PRESSURE DEVELOPING EAST OF THE BAHAMAS WILL MOVE NORTH AND NORTHWEST THROUGH MID WEEK...MOST LIKELY REMAINING OVER THE ATLANTIC...BEFORE SHIFTING EAST LATE IN THE WEEK. && .NEAR TERM /THROUGH MONDAY/... THE AREA WILL REMAIN ON THE WESTERN SIDE OF AN UPPER LOW DROPPING SOUTHEAST FROM THE MID-ATLANTIC REGION. BOUNDARY INTERACTIONS WITH THE SEABREEZE HAVE SUPPORTED CONTINUED CONVECTION ACROSS THE FORECAST AREA THIS EVENING...WITH UPPER LEVEL ENERGY SUPPORTING ORGANIZED SEVERE STORMS. LATEST RADAR TRENDS SHOW STRONG TO SEVERE CELLULAR CONVECTION ACROSS COASTAL SOUTH CAROLINA GENERALLY MOVING SOUTHWARD. WILL CONTINUE TO TRACK ONGOING CONVECTION FOR THE NEXT FEW HOURS...BEFORE THE LOSS OF DAYTIME HEATING AND INSTABILITY SUGGESTS COVERAGE WILL STEADILY DECREASE. ALTHOUGH MOST LOCALES SHOULD REMAIN DRY AFTER MIDNIGHT...CANNOT COMPLETELY RULE OUT ISOLATED SHOWERS/STORMS WITHIN CONTINUED ENHANCED UPPER LEVEL SUPPORT FROM THE APPROACHING LOW ALOFT. PATCHY FOG IS ALSO POSSIBLE...ESPECIALLY IN AREAS THAT SEE RAIN...BUT WILL NOT MENTION IN THE FORECAST AT THIS TIME. LOWS WILL BE IN THE MID TO UPPER 60S AWAY FROM THE SLIGHTLY MILDER BEACHES. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... MONDAY...MID AND UPPER CYCLONE OVER NC WILL DROP EAST OF THE AREA DURING THE DAY. AT THE SAME TIME AT TH E SURFACE...A HIGH PRESSURE WEDGE BEGINS TO STRENGTHEN ACROSS THE LOCAL REGION. WHILE THIS OCCURS...LOW PRESSURE IS SLOWLY DEEPENING EAST AND NE OF THE BAHAMAS. WITH A DEEPER AND STRENGTHENING EASTERLY FLOW BETWEEN THESE TWO SURFACE FEATURES RESULTING IN AN INCREASE IN LOW LEVEL CONVERGENCE...WE LOOK FOR AN INCREASE IN CLOUDINESS AND OUR RAIN CHANCES MONDAY. WITH LESS SHEAR AND INSTABILITY AND POOR LAPSE RATES...WE LOOK FOR A DECREASE IN T-STORM CHANCES...WITH MUCH OF THE PRECIP IN THE FORM OF SHOWERS. HOWEVER...WITH A 40 KT JET STREAK TO MOVE IN LATE...SHORT WAVES TO MOVE INTO SC IN ASSOCIATION WITH THE MID AND UPPER CYCLONE...AND COLDER 500 TEMPS DOWN TO -11 OR -12C WE STILL COULD EXPERIENCE A FEW STRONGER THUNDERSTORMS WITH THE INTERACTION OF BOUNDARIES. RAIN CHANCES WILL BE MAINLY IN THE 40 TO 50 PERCENT RANGE...EXCEPT SOME 60 PERCENT PROBABILITIES ION BERKELEY AND DORCHESTER IN CLOSER PROXIMITY TO SHORT WAVES AND JET STREAK ALOFT. TEMPS WILL BE NOTICEABLY LOWER THAN RECENT DAYS DUE TO THE ONSHORE FETCH...AND THE INCREASED CLOUD COVER AND PRECIP. WE WILL SHOW MAINLY UPPER 70S AND LOWER 80S...EXCEPT A FEW MID 80S ACROSS FAR SOUTHERN AREAS IF THEY RECEIVE ENOUGH BREAKS OF SUNSHINE. MONDAY NIGHT AND TUESDAY...HIGH PRESSURE WEDGE REMAINS ANCHORED INLAND...WITH ATLANTIC LOW PRESSURE STILL FAR TO THE SE AND MOVING ONLY SLOWLY NORTH AND NW. THE MID AND UPPER CYCLONE NEARBY MONDAY EVENING WILL BECOME ABSORBED BY A THE MID AND UPPER CYCLONE ASSOCIATED WITH THE SURFACE LOW OF THE ATLANTIC. RAIN CHANCES ARE DRIVEN MAINLY BY LOW LEVEL CONVERGENCE MONDAY NIGHT AND TUESDAY...AIDED BY WEAK SHORT WAVES ALOFT ROTATING AROUND THE MID AND UPPER CYCLONE. TUESDAY NIGHT THROUGH WEDNESDAY NIGHT...WITH THE SURFACE LOW CO-LOCATED UNDER THE MID AND UPPER CYCLONE AND A BLOCKING RIDGE TO THE NORTH OF THE SYSTEM...THE ATLANTIC LOW WILL STRUGGLE TOO MOVE TOO FAR NORTH THROUGH THE MIDDLE OF THE WEEK. ALTHOUGH IT MAY REACH OUR LATITUDE...PRESENT INDICATIONS ARE THAT THE SYSTEM WILL STAY FAR OFFSHORE OVER THE ATLANTIC. RAIN CHANCES WILL BE IN THE 20-30 PERCENT RANGE...HIGHEST OVER THE COASTAL AREAS AND IN THE ATLANTIC BASED ON THE LOW REMAINING WELL REMOVED FROM THE LOCAL AREA. THAT COULD CHANGE SHOULD THE TRACK/STRENGTH OF THE SYSTEM DEVIATE FROM THE LATEST THINKING. TEMPS WILL NOT STRAY TOO FAR FROM NORMAL. ALTHOUGH THE LOW WILL LIKELY STAY IN THE ATLANTIC...WE STILL COULD EXPERIENCE SOME IMPACTS LOCALLY. THAT WOULD BE THE RISK OF BEACH EROSION....AND THE POSSIBILITY OF SHALLOW COASTAL FLOODING WHICH WOULD COINCIDE WITH THE UPCOMING ASTRONOMICAL HIGH TIDES WITH THE FULL MOON. WE WILL DISCUSS THESE CONDITIONS IN OUR HAZARDOUS WEATHER OUTLOOK. && .LONG TERM /THURSDAY THROUGH SUNDAY/... AN UPPER RIDGE OVER THE GREAT LAKES REGION WILL PIN THE ATLANTIC LOW...DEVELOPING A BLOCKING PATTERN SUGGESTIVE OF A MEANDERING SURFACE SYSTEM THROUGH AT LEAST THURSDAY. ONCE THE UPPER LOW WEAKENS INTO MORE OF A PROGRESSIVE TROUGH...THE SURFACE LOW WILL BE TAKEN EAST FURTHER INTO THE ATLANTIC. THIS PATTERN SHIFT WILL ALLOW HIGH PRESSURE AT THE SURFACE AND ALOFT TO REBUILD OVER THE REGION FOR LATE WEEK INTO THE WEEKEND. EXPECT RAIN CHANCES TO BE LOWER THURSDAY THROUGH SATURDAY AS A RESULT. PERSISTENTLY CLOUDY SKIES WILL ALSO BREAK BY LATE WEEK...AND WHEN COMBINED WITH INCREASING HEIGHTS ALOFT...WILL SUPPORT A WARMING TREND INTO THE WEEKEND. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... SCATTERED CONVECTION CONTINUES ACROSS THE FORECAST AREA THIS EVENING. AT 00Z TAF TIME...A LARGE SEVERE THUNDERSTORM HAS PASSED SOUTH OF KCHS. MORE CELLULAR CONVECTION HAS DEVELOPED BEHIND THE SEABREEZE IN THE VICINITY OF THE KSAV TERMINAL...AS THE LARGE SEVERE STORM APPROACHES FROM THE NORTH. WILL THUS CONSIDER AN AMENDMENT TO THE KSAV TAF TO ACCOUNT FOR SHOWERS/THUNDERSTORMS DURING THE NEXT FEW HOURS. THERE IS LESS CERTAINTY IN CONVECTIVE COVERAGE AFTER AROUND 03Z...AND HAVE THUS PREFERRED NOT TO MENTION RA/TS UNTIL NIGHTTIME TRENDS BECOME MORE CLEAR. OF SOME CONCERN IS THE FORMATION OF FOG LATE TONIGHT...ESPECIALLY SINCE BOTH KCHS AND KSAV WILL LIKELY EXPERIENCE PRECIPITATION WITH THESE EVENING STORMS. PERSISTENT CLOUD COVER COULD HINDER FOG DEVELOPMENT...AS UPPER LEVEL ENERGY TO THE NORTH SUPPORTS CONTINUED PRECIPITATION AND CLOUDS FOR THE MID ATLANTIC AND CAROLINA COAST OVERNIGHT. HAVE ADDED MVFR VISIBILITIES AT BOTH TERMINALS BETWEEN 02Z AND 14Z...AND WILL MONITOR TRENDS IF CONDITIONS BEGIN TO TAKE A MORE PESSIMISTIC TURN. UNSETTLED WEATHER WILL PERSIST INTO MONDAY...WITH BEST RAIN CHANCES TRANSITIONING BACK TO NORTHERN AREAS. HAVE THUS MAINTAINED A -RA FOR THE MORNING HOURS AT KCHS...THEN JUST COVER RAIN/THUNDER POTENTIAL WITH CB TOWARD THE END OF THE TAF PERIOD. EXTENDED AVIATION OUTLOOK...MVFR CONDITIONS POSSIBLE AT TIMES MONDAY AFTERNOON THROUGH WEDNESDAY...WITH AN INCREASE IN RAIN CHANCES. && .MARINE... TONIGHT...AN EAST TO NORTHEAST FLOW REGIME WILL PERSIST AS HIGH PRES SLOWLY STRENGTHENS N OF THE AREA. WINDS WILL GENERALLY REMAIN 10 KT OR LESS WITH SEAS 3-4 FT OR LESS...MAINLY IN SOUTHEAST SWELL. MONDAY THROUGH FRIDAY...THE PRESSURE GRADIENT STEADILY TIGHTENS ACROSS THE MARINE COMMUNITY DURING THE EARLY AND MIDDLE PART OF THE WEEK. INITIALLY THIS IS A RESULT OF STRONGER HIGH PRESSURE BUILDING FROM THE NORTH WITH A RESULTING WEDGE SETTING UP INLAND. BUT AS LOW PRESSURE OVER THE SW ATLANTIC MOVES NORTH AND NW IN AN AREA WELL OFF THE SE COAST...OUR GRADIENT PINCHES FURTHER...DEPENDING UPON THE TRACK...STRENGTH AND TIMING OF THAT LOW. CONDITIONS APPEAR TO REMAIN BELOW ANY SCA CONDITIONS MONDAY...CAPPING WINDS AND SEAS AT 15 KT AND 4 FEET...RESPECTIVELY. BUT WINDS AND SEAS WILL BE ON THE INCREASE STARTING MONDAY NIGHT AND TUESDAY...AS THE ATLANTIC LOW SHIFTS A BIT CLOSER TO THE WATERS. THERE IS STILL SOME UNCERTAINTY ON THE STRENGTH OF THE PINCHING BETWEEN THIS LOW AND THE INLAND WEDGE. AFTER CONSIDERING OUR INTER-OFFICE COORDINATION...WE HAVE DECIDED AGAINST RAISING ANY SCA/S AT THIS TIME. BUT ODDS DO FAVOR SCA/S WILL BE REQUIRED AT SOME POINT FOR THE MID WEEK PERIOD. IN FACT WE STILL CANNOT ENTIRELY RULE OUT THE POSSIBILITY OF GALES. GIVEN THAT THERE IS STILL MUCH UNCERTAINTY REGARDING THE DEVELOPMENT AND EVENTUAL TRACK AND STRENGTH OF THIS SYSTEM. ALL MARINERS ARE URGED TO REMAIN ABREAST OF THE MARINE FORECAST FOR FURTHER UPDATES. PREFERRED MODEL SOLUTIONS INDICATE THE LOW PRESSURE SYSTEM WILL DRIFT BACK EAST THROUGH THE ATLANTIC AROUND THURSDAY...ALLOWING WINDS AND SEAS TO DIMINISH BY LATE IN THE WEEK. WILL THUS INDICATE SLOWLY IMPROVING CONDITIONS FOR THURSDAY AND FRIDAY. RIP CURRENTS...WE RECEIVED REPORTS OF RIP CURRENTS AT FOLLY BEACH THE PAST 2 DAYS...AND CONDITIONS LOOK JUST AS GOOD IF NOT BETTER FOR MONDAY. WITH A PERSISTING ONSHORE WIND AND A CONTINUATION OF SMALL 2-3 FOOT SWELLS AT THE BEACHES...PLUS THE UPCOMING FULL MOON...WE HAVE OPTED FOR A MODERATE RISK OF RIP CURRENTS MONDAY. CONDITIONS APPEAR FAVORABLE FOR RIP CURRENTS AGAIN TUESDAY AND WEDNESDAY...AS EVEN LARGER SWELLS IMPACT THE BEACHES IN RESPONSE TO LOW PRESSURE IN THE ATLANTIC. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. &&
