The episode as NWS CHS wrote it up.
A trough of low pressure over the region in combination with numerous differential heating boundaries and the inland pushing sea breeze, resulted in scattered thunderstorm development 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 Jul 15, 2:42 PM EST, 1 hour 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 342 PM EDT THU JUL 15 2010 .SYNOPSIS... HIGH PRESSURE WILL PREVAIL THROUGH THE WEEK AS A TROUGH OF LOW PRES REMAINS INLAND. && .NEAR TERM /THROUGH TONIGHT/... SCATTERED TO NUMEROUS TSTMS HAVE RAPIDLY DEVELOPED SINCE 1 PM WITH THE GREATEST CONCENTRATION OCCURRING OVER THE EASTERN MIDLANDS...CSRA AND EAST-CENTRAL GEORGIA AHEAD OF A WEAK SURFACE TROUGH. SBCAPES NEAR 4000 J/KG AND LI NEAR -9C WILL SUPPORT CONTINUED DEVELOPMENT OVER THE NEXT SEVERAL HOURS. RUC AND 4KM-WRF OUTPUT SUGGEST THE GREATEST TSTM CONCENTRATION WILL OCCUR ACROSS THE INTERIOR WHERE OUTFLOWS GENERATED FROM ONGOING CONVECTION WILL INTERSECT THE INLAND MOVING SEA BREEZE. WILL CONTINUE TO HIGHLIGHT 50-60 PERCENT POPS THROUGH 6 PM WITH CHANCE POPS DOMINATING FOR THE REST OF THE EVENING HOURS. EXPECT MAINLY DRY CONDITIONS TO PREVAIL BY MIDNIGHT...BUT MODEL DATA SUGGEST ISOLATED TO SCATTERED CONVECTION WILL REDEVELOP OVER THE COASTAL WATERS AND CHARLESTON COUNTY COAST AS A NOCTURNAL SURGE DEVELOPS OFFSHORE. WILL SHOW 20-30 PERCENT POPS FOR CHARLESTON AND EASTERN BERKELEY COUNTIES TO TREND. WARM AND MUGGY CONDITIONS WILL PREVAIL WITH LOWS FROM THE MID-UPPER 70S WITH LOWER 80 NEAR THE BEACHES/HARBOR. THERE WILL BE A CONTINUED RISK FOR DAMAGING WINDS IN THE STRONGER TSTMS THIS AFTERNOON WITH DCAPES FORECAST TO EXCEED 1000 J/KG WITH DELTA EPT NUMBERS AROUND 38C AND WET-MICROBURST SEVERITY INDICES OVER 115. BECAUSE 0-6KM SHEAR IS FAIRLY LIGHT...EXPECT THE SEVERE POTENTIAL TO REMAIN FAIRLY LIMITED AND MAINLY CONFINED TO THE STRONGEST MULTICELLULAR CLUSTERS WHOSE UPDRAFTS BECOME ENHANCED BY MESOSCALE BOUNDARY COLLISIONS. CONDITIONS ALSO FAVOR RATHER INTENSE CLOUD-TO-GROUND LIGHTNING AS WELL AS LOCALLY HEAVY RAINFALL GIVEN SLOW STORM MOVEMENTS AND PWATS IN EXCESS OF 2 INCHES. && .SHORT TERM /FRIDAY THROUGH SUNDAY NIGHT/... A SHEAR AXIS ACROSS THE THE CAROLINA COASTLINE WILL LIFT FARTHER NORTH ON FRIDAY...WITH ASSOCIATED SHORTWAVE ACTIVITY DIMINISHING OVER THE AREA. ATLANTIC RIDGING AT THE SURFACE AND ALOFT WILL STEADILY BUILD TOWARD THE EAST COAST AT THE SAME TIME...WHILE DEEPEST MOISTURE IS SUBSEQUENTLY PUSHED INLAND. SHOWER/THUNDERSTORM POTENTIAL WILL THUS BE LOWER ON FRIDAY COMPARED TO PREVIOUS DAYS...DRIVEN MAINLY BY SEABREEZE AND BOUNDARY INTERACTIONS. POP SCHEME IS REPRESENTATIVE OF A TYPICAL SUMMERTIME SCENARIO...AS RAIN CHANCES RANGE FROM 20 PERCENT ALONG THE COAST TO 30 PERCENT INLAND OF THE SEABREEZE. BOTH GFS AND NAM MODELS SHOW WEAK SHORTWAVE ACTIVITY BRIEFLY BRUSHING THE NORTHERN FORECAST AREA ON SATURDAY. THIS INCREASED UPPER LEVEL SUPPORT COMBINED WITH THE DEVELOPING INLAND SURFACE TROUGH...AS WELL AS PWAT VALUES RISING BACK UP TO 2 INCHES...COULD ENHANCE CONVECTIVE POTENTIAL SLIGHTLY DURING THE AFTERNOON AND EVENING HOURS. DRIER AIR WILL THEN RE-SURGE ONSHORE BENEATH THE ATLANTIC RIDGE BY SUNDAY...AND MODELS SUGGEST THAT PRECIPITATION COULD BE SUPPRESSED OVER COASTAL COUNTIES. WILL KEEP POPS IN THE SOLID CHANCE RANGE FOR THE WESTERN HALF OF THE FORECAST AREA CLOSEST TO THE INLAND TROUGH AND DEEPER MOISTURE...WHILE REDUCING THUNDERSTORM CHANCES FOR THE EASTERN HALF. TEMPERATURES FRIDAY THROUGH THE WEEKEND WILL NOT VARY GREATLY. EXPECT HIGH TEMPERATURES TO REACH THE LOWER 90S AWAY FROM THE LOCALLY COOLER COASTLINE EACH AFTERNOON. OVERNIGHT LOW TEMPERATURES WILL ONLY FALL INTO THE LOWER TO MID 70S. && .LONG TERM /MONDAY THROUGH WEDNESDAY/... LOW AND MID LEVEL RIDGE STRENGTHENS DURING THE EARLY AND MIDDLE PART OF NEXT WEEK...IN THE WAKE OF DEPARTING SHORTWAVE ACTIVITY FROM THE WEEKEND. INDICATIONS ARE THAT 500 MB HEIGHTS WILL REACH AS HIGH AS 595/596 METERS. WITH WARM MID LEVEL AIR AND THE MOISTURE AXIS TO REMAIN NORTH AND WEST OF THE REGION...WILL CARRY ONLY 20-30 POPS THE FIRST PART OF NEXT WEEK. TEMPS WILL WARM AT LEAST INTO THE LOWER AND MIDDLE 90S...AND WITH DEW POINTS PERHAPS AS HIGH AS THE LOWER AND MIDDLE 90S...ARE LOOKING AT THE POSSIBILITY OF HEAT ADVISORIES. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... VFR CONDITIONS WILL PREVAIL THROUGH THE FIRST 24 HOURS. THERE IS A CHANCE OF SHOWERS/THUNDERSTORMS WITH MVFR CONDITIONS THIS AFTERNOON AT BOTH TERMINALS...BUT CONFIDENCE REMAINS LOW IN TIMING/ DURATION OF THE EVENT. THEREFORE...HAVE MAINTAINED CB AT BOTH TERMINALS THROUGH SUNSET TODAY. CONDITIONS SHOULD REMAIN DRY OVERNIGHT. SOUTH SOUTHWEST WINDS AT OR BELOW 10 KNOTS ARE EXPECTED TO DEVELOP BY 15Z FRIDAY. EXTENDED AVIATION OUTLOOK...OUTSIDE OF A BRIEF PERIOD OF MARGINAL MVFR WEATHER IN LATE NIGHT/EARLY MORNING FOG...AND IN AFTERNOON/EVENING CONVECTION...CONDITIONS WILL BE MAINLY VFR THROUGH MONDAY. && .MARINE... EXPECT A NOCTURNAL SURGE TONIGHT BUT WINDS SHOULD BE NO HIGHER THAN 15-20 KT WITH SEAS 3-5 FT. ATLANTIC HIGH PRESSURE WILL BECOME THE DOMINANT WEATHER FEATURE FOR THE COASTAL WATERS INTO EARLY NEXT WEEK. THIS PATTERN WILL SUPPORT A TYPICAL SUMMERTIME SOUTHERLY SURFACE FLOW. DESPITE SEA BREEZE CIRCULATIONS IN THE AFTERNOON/EVENING AND NOCTURNAL SURGES...WIND SPEEDS WILL LIKELY REACH NO HIGHER THAN AROUND 15 KT. SEAS WILL HOLD AT 5 FT OR LESS THROUGH THE PERIOD...A COMBINATION OF 2 TO 4 FT SOUTHERLY WIND WAVES AND SOUTHEAST SWELLS OF 2 TO 3 FT EVERY 8 OR 9 SECONDS AS THE RIDGE PERSISTS. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. &&
