The episode as NWS CHS wrote it up.
Deep tropical moisture in combination with an upper level disturbance resulted in numerous showers and thunderstorms along with heavy rainfall across southeast Georgia.
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 31, 12:30 PM EST, 1 hour 46 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 130 PM EDT MON MAY 31 2010 .SYNOPSIS... AN UPPER LEVEL DISTURBANCE OVER THE SOUTHERN TENNESSEE VALLEY TODAY WILL WEAKEN AND GRADUALLY LIFT E THROUGH THE MID ATLC REGION ON TUE DELIVERING PERIODS OF UNSETTLED CONDITIONS TO THE REGION. ATLC HIGH PRES WILL CONTINUE DURING MID WEEK...THEN A COLD FRONT MAY APPROACH FROM THE W LATE IN THE WEEK. && .NEAR TERM /UNTIL 7 PM THIS EVENING/... THIS MEMORIAL DAY WILL BE AN ACTIVE ONE FOR MANY LOCATIONS...WITH SCATTERED TO NUMEROUS CONVECTION IN MOST LOCATIONS...EVEN CATEGORICAL IN SOME AREAS. ISOLATED SEVERE WEATHER IS POSSIBLE...WHICH WE WILL DISCUSS BELOW. ACTIVITY THAT WAS ONGOING OVERNIGHT AND EARLY THIS MORNING ACROSS THE CENTRAL CWFA HAS PERSISTED...BUT TRENDED WEAKER AND HAS PUSHED NORTH AND NE INTO THE NORTHERN QUARTER OF THE REGION. WHILE THE DECREASING TREND WILL PERSIST WITH THIS ACTIVITY...THERE HAS BEEN A QUICK FLARE UP OF CONVECTION ELSEWHERE WITH CONVECTIVE TEMPS IN THE UPPER 70S TO AROUND 80. THE SEA BREEZE...ALREADY WEST OF US-17 WILL CONTINUE TO SEE AN INCREASE IN COVERAGE AS IT SHIFTS SLOWLY WESTWARD. FURTHER INLAND...VARIOUS BOUNDARIES ARE EVIDENT...FROM DIFFERENTIAL HEATING OVER SOUTHEAST GA...TO SHORT WAVES ALOFT EMBEDDED WITHIN THE SW FLOW ALOFT AROUND THE WEAKENING LOW OVER THE TN VALLEY. WITH PWATS AS HIGH AS NEAR 2 INCHES AND MODERATE TO STRONG INSTABILITY WE LOOK FOR A WET MEMORIAL DAY FOR MUCH OF THE AREA. CONVECTION WILL CONTINUE TO INCREASE IN BOTH COVERAGE AND INTENSITY THIS AFTERNOON. MULTICELL STORMS WILL IMPACT MAINLY THE CENTRAL AND SOUTHERN CWFA...WITH THE POTENTIAL FOR SOME STORMS TO BECOME STRONG OR EVEN SEVERE. WE HAVE UPDATED THE HWO AND ZFP TO ACCOUNT FOR THE SEVERE POTENTIAL...MAINLY ACROSS OUR WESTERNMOST ZONES. THIS INCLUDES ALLENDALE AND HAMPTON COUNTIES IN SC...AND FROM JENKINS AND SCREVEN TO TATTNALL COUNTIES IN GA. MODIFIED MORNING SOUNDINGS AT KCHS AND KJAX DO SHOW LIMITED COVERAGE IN CHARLESTON COUNTY AND MUCH OF BERKELEY COUNTY WITH K-INDEX OF ONLY 19...WITH MORE SUBSIDENCE IN ASSOCIATION TO THE DEPARTING UPPER RIDGE THAN ELSEWHERE. BUT AS WE TRACK FURTHER SOUTH AND WEST WITH MID LEVEL DYNAMICS AND BOUNDARY INTERACTIONS WE WILL SEE MUCH HIGHER COVERAGE AND THE RISK OF STRONG TO SEVERE WEATHER. MODIFIED SOUNDINGS SHOW SBCAPES OF 2500 J/KG OR GREATER...TOTAL TOTALS UP TO 48 OR 49...LIFTED INDEX -6 AND DECENT MID LEVEL LAPSE RATES NEAR 6C. WITH DCAPES APPROACHING 800-1200 J/KG OUR MAIN RISK IS WIND. BUT WITH 500 TEMPS NEAR -10C AND CAPE IN THE HAIL GROWTH ZONE OVER 800 J/KG...THERE IS CERTAINLY A RISK OF LARGE HAIL. STORM MOTION IS SOUTHERLY THIS MORNING BUT WILL VEER TO MORE SW THIS AFTERNOON. BUT WITH SPEEDS OF NO MORE THAN 10 OR 12 KT...LOCALLY HEAVY RAINFALL WILL OCCUR. IN FACT...ODDS FAVOR A FEW FLOOD ADVISORIES BEING REQUIRED WITH SUCH HIGH PWATS. REGARDING THE POP SCHEME THIS AFTERNOON...WE HAVE CARRIED 20-30 POPS FAR NE...TO 40-60 POPS MOST ELSEWHERE...EXCEPT AS HIGH AS 70-80 POPS ALONG THE WESTERN ZONES. TEMPS WILL BE LIMITED BY THE CLOUD COVER AND LARGE COVERAGE OF CONVECTION...AND MIDDLE 80S LOOKS ABOUT THE HIGHEST FOR MOST PLACES...MAYBE A FEW UPPER 80S ACROSS INTERIOR SE GA. THE BEACHES WILL SEE LESS COVERAGE OF STORMS TODAY...BUT WITH ONSHORE FETCH THEY WILL ONLY REACH AROUND 80. && .SHORT TERM /7 PM THIS EVENING THROUGH WEDNESDAY NIGHT/... TONIGHT...A VORT LOBE ASSOCIATED WITH WHAT ONCE WAS THE CUT OFF LOW WILL NE OF THE FORECAST AREA DURING THE NIGHT....WITH ITS ASSOCIATED PVA PUSHING E INTO THE ATLANTIC AFTER MIDNIGHT. INSTABILITY WILL SHIFT TO THE ATLC WATERS. THE CHANCE FOR RESIDUAL SHOWERS AND FEW TSTMS TO PERSIST OVERNIGHT SEEMS HIGHEST ALONG COASTAL SOUTH CAROLINA WHERE LOW LEVEL MOISTURE CONVERGENCE BISECTS THE CAPE GRADIENT TO THE N OF BEAUFORT. TO THE W OF I-95 OVERNIGHT...THERE COULD BE QUITE A BIT OF STRATUS DEVELOPMENT IN THE MOIST LOW LEVEL AIR MASS BUT THE OVERALL PATTERN AND RESIDUAL CLOUDS DO NOT SUGGEST ANY SIGNIFICANT FOG DEVELOPMENT. ON TUE...850 MB THETA-E IS FORECAST TO POOL N FROM EASTERN SOUTH CAROLINA INTO THE SANDHILLS AND COASTAL PLAIN OF NORTH CAROLINA AS THE REMNANT SHORT WAVE FROM THE EJECTING LIFTING MID LEVEL LOW PRES SYSTEM PASSES OFF TO OUR N. WE EXPECT THIS FEATURE AND IT/S AMPLE MOISTURE SUPPLY WILL ENHANCE DIURNAL CONVECTION OVER MUCH OF EASTERN SOUTH CAROLINA. SLIGHTLY LESSER EFFECTS FROM THIS FEATURE IN SE GEORGIA BUT ANOTHER SHORT WAVE MOVING OUT OF THE NE GULF OF MEXICO COULD ENHANCE SEA BREEZE SHOWERS AND STORMS. BOTTOM LINE IS 50 POPS N TO 30-40 PERCENT CLOSER TO THE ALTAMAHA. HIGH TEMPERATURES WARMER BY SEVERAL DEGREES ON TUE...ESPECIALLY IN GEORGIA. SHOWERS AND STORMS SHOULD DIMINISH IN COVERAGE AND INTENSITY TUE NIGHT WITH ONLY SLIGHT CHANCES FOR COASTAL CONVERGENCE SHOWERS AND ISOLATED TSTMS TOWARD DAWN WITH INLAND AREAS MAINLY DRY TO START THE DAY. ON WED...PLENTY OF MOISTURE AND INSTABILITY LINGER ACROSS OUR REGION AND WEAK VORT LOBES ON THE BACK-SIDE OF THE ATLC RIDGE LIKELY ADDING A BIT OF A FOCUS FOR SCATTERED AFTERNOON AND EARLY EVENING CONVECTION. WE MAINTAINED DECENT CHANCE POPS IN THE 30-40 PERCENT RANGE WITH HIGHS UPPER 80S TO AROUND 90. && .LONG TERM /THURSDAY THROUGH SUNDAY/... GLOBAL MODELS CONTINUE TO DEVIATE ON STRENGTH AND TIMING OF MID LATITUDE SHORT WAVES EXPECTED TO MOVE INTO THE EASTERN THIRD OF THE U.S. LATE WEEK. WITHOUT MUCH FAITH IN DETAILS AT THIS POINT WE HAVE CONTINUED ALONG THE SAME PATH IN THE MEDIUM RANGE. WE LOOK TO BE GETTING INTO A NW FLOW ALOFT AND THIS PATTERN SUGGESTS OUR REGION COULD BE OPEN TO BOUTS OF CONVECTION COMING OFF THE MOUNTAINS THU AND FRI. THE SURFACE PATTERN SUGGESTS A WARMER THAN CLIMO REGIME WITH A SW LOW LEVEL FLOW. OVER THE WEEKEND...THE 00Z GFS INDICATES A POTENTIAL FOR HOT WEATHER WITH A LARGE UPPER RIDGE BUILDING INTO A FAVORABLE POSITION TO DELIVER MUCH HIGHER THAN CLIMO READINGS BOTH NIGHT AND DAY. WE HAVE BUMPED OUR READINGS HIGHER TO TREND...ESPECIALLY IN LIGHT OF A MUCH WARMER LOOKING 00Z ECMWF MODEL RUN EARLY THIS MORNING. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... KCHS...SEA BREEZE BOUNDARY HAS PUSHED INLAND FROM THE TERMINAL...THUS OUR RISK OF AFTERNOON CONVECTION IS OVER WITH. HOWEVER...WITH THE APPROACH OF A SHORT WAVE TONIGHT AND THE STEERING FLOW VEERING AROUND TO THE SW...SOME OF THE CONVECTION MAY ATTEMPT TO MOVE BACK IN AFTER MIDNIGHT. THUS OUR REASONING FOR ADDING CB CLOUDS BACK IN BY 06Z. FOR LATE TONIGHT AND INTO TUESDAY MORNING...THE SOUTH TO SW FLOW OFF THE ATLANTIC IN CONJUNCTION WITH THE DEEP FEED OF MOISTURE COULD ALLOW FOR A FEW SHRA OR EVEN TSRA TO IMPACT THE AIRPORT. PROBABILITIES APPEAR HIGH ENOUGH TO WARRANT A TEMPO GROUP OF MVFR CONDITIONS FROM 08-12Z. OTHERWISE...MAINLY VFR CIGS TO PREVAIL WITH THE 18Z TAFS. KSAV...LINGERING CONVECTION WILL PROGRESS STEADILY INLAND THE REST OF THE AFTERNOON...THUS OUR RISK OF FURTHER CONVECTION OTHER THAN A LIGHT SHRA THROUGH 19Z IMPACTING THE TERMINAL HAS ENDED. AS THE SHORT WAVE PASSES THROUGH TONIGHT THERE CERTAINLY COULD BE ISOLATED SHRA OR TSRA IMPACTING THE AIRPORT...BUT PROBABILITIES ARE LESS THAN 30 PERCENT SO NO NEED TO CARRY IN THE TAFS AT THIS TIME. A BETTER CHANCE EXISTS FOR LOW STRATUS AND LIGHT FOG GIVEN THE RAINFALL FROM EARLIER TODAY...THUS WE SHOW MVFR CONDITIONS FROM 08-1330Z TUESDAY. POTENTIAL HOWEVER DOES EXIST FOR EVEN IFR CONDITIONS...AND/OR THE MVFR WEATHER LASTING FOR A LONGER PERIOD. EXTENDED AVIATION OUTLOOK...BOUTS OF MAINLY DIURNAL SHWRS/TSTMS ARE EXPECTED EACH AFTERNOON AND EVENING IN THE VICINITY OF THE COASTAL TAF CORRIDOR. AT LEAST SLIGHT CHANCES OF MVFR OR LOWER CIGS/VSBYS POSSIBLE A FEW HOURS AROUND DAWN EACH DAY THROUGH MID WEEK. && .MARINE... THE ATLANTIC RIDGE WILL REMAIN ANCHORED ACROSS THE LOCAL WATERS THIS AFTERNOON...WITH SE TO SOUTH WINDS AT 15 KT OR LESS TO RESULT. THE EXCEPTION WILL BE IN CHARLESTON HARBOR AND NEAR THE IMMEDIATE COAST...WITH SEA BREEZE CIRCULATION TO ALLOW FOR WINDS BETWEEN 15 AND 20 KT THROUGH THIS EVENING. WITH THE COMBINATION OF 2-3 FOOT WIND WAVES AND 2-4 FOOT SWELL WAVES...AND THE DOMINANT WAVE PERIOD WILL BE AROUND 5-7 SECONDS THROUGHOUT THE DAY. THUS CONDITIONS MAY BE A LITTLE ROUGH FOR SOME RECREATIONAL BOATERS. ATLC RIDGING WILL HOLD FIRM TONIGHT...MAINTAINING A SE TO S WIND REGIME. SPEEDS WILL REMAIN LESS THAN 15 KT WITH SEAS 2-4 FT IN THE NEARSHORE WATERS...4-5 FT IN THE GA OUTER WATERS. TUESDAY THROUGH FRIDAY...ATLC RIDGING WILL REMAIN ACROSS THE COASTAL WATERS THROUGH MUCH OF THE WEEK...ALTHOUGH MINOR FLUCTUATIONS IN ITS STRENGTH WILL OCCUR BUT WITH NEGLIGIBLE EFFECTS. GENERALLY SE TO S WINDS WILL PREVAIL. DESPITE THE SEA BREEZE EACH AFTERNOON AND EVENING AND SUBTLE NOCTURNAL SURGES EACH NIGHT...WINDS WILL GENERALLY REMAIN AT 15 KT OR LESS. SEAS WILL CONTINUE TO BE A COMBINATION OF 2 TO 3 FOOT WIND WAVES AND 2 TO PERHAPS 3 FOOT SWELLS...WHICH AVERAGES OUT TO COMBINED SEAS NO HIGHER THAN 3 OR 4 FEET. DOMINANT WAVE PERIOD THROUGH MID WEEK WILL GENERALLY BE BETWEEN 5 AND 7 SECONDS. RIP CURRENTS...WITH REPORTS OF BREAKERS UP TO 3 FEET IN THE SURF ZONE...SWELLS OF 2-3 FEET EVERY 6 SECONDS IMPACTING THE BEACHES AND WINDS TO REMAIN BETWEEN 15 AND 20 MPH...WE HAVE OPTED TO GO WITH A MODERATE RISK OF RIP CURRENTS THE REST OF THE DAY. GIVEN THE LARGE VOLUME OF BEACHGOERS FOR THE HOLIDAY...IT SEEMS A SAFE CHOICE TO GO WITH THE HIGHER RISK. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. && 33
