Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS CHS wrote it up.
An inland trough and seabreeze initiated showers and thunderstorms in an unstable atmosphere during the afternoon and evening hours. Additional showers and thunderstorms developed during early overnight hours as a back door cold front lingered in persistent unstable conditions. High DCAPES suggested thunderstorms capable of producing damaging wind gusts.
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 Jun 18, 2:19 PM EST, 16 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 319 PM EDT FRI JUN 18 2010 .SYNOPSIS... A WEAK COLD FRONT WILL SAG INTO THE REGION TODAY THEN GRADUALLY DISSIPATE SAT. DEEP LAYERED HIGH PRES WILL REBUILD ON SUNDAY AND DOMINATE THE WEATHER PATTERN DURING MUCH OF THE UPCOMING WEEK. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... SCATTERED CONVECTION HAS DEVELOP ACROSS PORTIONS OF THE CWA THIS AFTERNOON...MAINLY ACROSS SOUTHEAST SOUTH CAROLINA. MANY THUNDERSTORMS HAVE PRODUCED TORRENTIAL RAINFALL AS 12Z MODEL SOUNDING FROM KCHS SHOWED PWATS AROUND 2 INCHES. ALSO...MODEL SOUNDINGS SHOWED VERY WEAK STORM MOTION WHICH HAS RESULTED IN VERY SLOW MOVING STORMS. THE COMBINATION OF SLOW MOVING OR NEARLY STATIONARY STORMS AND HEAVY RAINFALL COULD LEAD TO SOME ISOLATED LOCALIZED FLOODING. EXPECT CONVECTION TO SPREAD ACROSS SOUTHEAST GEORGIA AND REDEVELOP ALONG OUTFLOW BOUNDARIES...THUS HAVE CHANCE POPS FOR MAJORITY OF THE CWA PRIOR TO SUNSET. EXPECT SCATTERED CONVECTION TO DISSIPATE DUE TO LOSS OF HEATING THIS EVENING...BUT WILL MAINTAIN A SMALL AREA OF CHANCE POPS AFTER SUNSET FOR FAR INLAND AREAS ACROSS SOUTHEAST GEORGIA AND SOUTHEAST SOUTH CAROLINA AS CONVECTION COULD DEVELOP ALONG ANY LINGERING BOUNDARIES. EXPECT PARTLY CLOUDY SKIES TO PERSIST OVERNIGHT WHICH SHOULD KEEP LOW TEMPERATURES ONCE AGAIN ABOVE NORMAL. EXPECT LOW TEMPERATURES IN THE LOW 70S FOR MOST AREAS AND MID TO UPPER 70S CLOSER TO THE COAST. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/... SATURDAY...THE MID-LEVEL SHEAR AXIS ALONG THE EASTERN FLANKS OF THE SUBTROPICAL RIDGE CENTERED OVER THE LOWER MISSISSIPPI VALLEY WILL REMAIN ACROSS SOUTH CAROLINA AND GEORGIA INTO SATURDAY. A BROADLY DIFLUENT FLOW ALOFT COMBINED WITH MODEST INSTABILITY WILL YIELD ANOTHER AIRMASS DRIVEN CONVECTIVE REGIME WITH ISOLATED TO SCATTERED SHOWERS AND TSTMS DEVELOPING FROM LATE MORNING THROUGH THE EARLY EVENING HOURS. THE PRIMARY FORCING MECHANISMS WILL REMAIN ON THE MESOSCALE....MAINLY CONFINED TO THE SEA BREEZE...THE LAKE MOULTRIE/MARION LAKE BREEZE AND ANY CONVECTIVE OUTFLOWS THAT CAN BE GENERATED. CONVECTIVE TEMPERATURES LOOK TO REMAIN AROUND 90 DEGREES...SO EXPECT THE MORNING HOURS TO REMAIN PRIMARILY DRY WITH CONVECTION BECOMING MORE SCATTERED IN NATURE AS THE AFTERNOON PROGRESSES AND MESOSCALE PROCESSES--I.E. BOUNDARY COLLISIONS--TAKE HOLD. WILL MAINTAIN A 20-40 POP DISTRIBUTION WITH THE HIGHEST GRIDDED POPS CONFINED TO THE WEST. MODEL SOUNDINGS SHOW DCAPES REACHING AS HIGH AS 1500-1800 J/KG WEST OF THE I-95 CORRIDOR BY EARLY AFTERNOON SO THE GREATEST RISK FOR STRONG TO SEVERE TSTMS WILL BE IN THIS AREA. OTHERWISE...LOCALLY HEAVY RAINFALL WILL REMAIN A POSSIBILITY WITH PWATS IN EXCESS OF 2 INCHES AND STORM MOTIONS OF LESS THAN 10 KT. HIGHS WILL REACH INTO THE LOWER-MID 90S AWAY FROM THE COAST WITH MID-UPPER 80S AT THE BEACHES. TSTMS WILL GRADUALLY DIMINISH DURING THE EVENING HOURS AS SURFACE BASED INSTABILITY WANES AND LOW-LEVEL CONVERGENCE SHIFTS BACK INTO THE COASTAL WATERS. LOWS WILL DROP INTO THE LOWER-MID 70S WITH UPPER 70S ALONG THE IMMEDIATE COAST. SUNDAY...THE ELONGATED SHEAR AXIS WILL SLOWLY SHIFT SOUTH AND BECOME ORIENTED SOUTHWEST-NORTHEAST ON SUNDAY AS THE MID-LEVEL RIDGE NUDGES EAST ACROSS TENNESSEE AND NORTH CAROLINA. MODELS SHOW A SLUG OF LOWER 850-700MB THETA-E FILTERING SOUTH INTO THE NORTHERN PARTS OF THE FORECAST AREA AS SUBSIDENCE WITH THE BUILDING RIDGE INCREASES. THIS WILL LIKELY ACT TO SUPPRESS CONVECTION SOMEWHAT...BUT STILL EXPECT ISOLATED TO LOW-END SCATTERED SHOWERS AND TSTMS TO FIRE DURING THE LATE AFTERNOON AS THE SEA BREEZE MOVES INLAND. WILL FORECAST 20-30 PERCENT POPS WITH THE HIGHEST POPS CLUSTERED OVER INTERIOR SOUTHEAST GEORGIA WHERE INSTABILITY AND LOW-LEVEL MOISTURE PROFILES WILL BE THE MOST FAVORABLE FOR TSTM DEVELOPMENT. HIGHS WILL LIKELY BE A FEW DEGREES WARMER COMPARED TO SATURDAY WITH MID 90S DOMINATING AWAY FROM THE BEACHES WITH A FEW UPPER 90S POSSIBLE ACROSS THE FAR INTERIOR. ALTHOUGH DEWPOINTS WILL LIKELY MIX OUT INTO THE UPPER 60S WELL INLAND...DEWPOINTS SURGING BACK TO THE MID 70S IN THE WAKE OF THE SEA BREEZE MAY SUPPORT HEAT INDEX VALUES BRIEFLY APPROACHING 105 IN A FEW LOCALES. CONVECTION WILL QUICKLY DISSIPATE SUNDAY EVENING AS THE RIDGE BUILD IN FROM THE NORTH AND INSTABILITY WANES. LOWS WILL BE IN THE LOWER-MID 70S WITH UPPER 70S ALONG THE BEACHES. MONDAY...SUBTROPICAL RIDGING WILL DOMINATE BY MONDAY AS THE MID-LEVEL SHEAR AXIS SHIFTS WELL TO THE SOUTH. THE CENTER OF THE RIDGE IS FORECAST TO REMAIN OVER TENNESSEE SO ITS FULL EFFECTS WILL NOT BE FELT THIS FAR SOUTH. STILL...THERE WILL BE ENOUGH SUBSIDENCE TO PRETTY MUCH CONFINE ANY SHOWERS AND TSTMS THAT DEVELOP TO THE ISOLATED CATEGORY. THE BEST CHANCES FOR ISOLATED ACTIVITY WILL REMAIN WEST OF I-95. IT WILL BE RATHER WARM FOR MID-JUNE WITH HIGHS IN THE MID-UPPER 90S...EXCEPT UPPER 80S-LOWER 90S AT THE COAST. DEWPOINTS WILL LIKELY MIX OUT SIMILAR TO SUNDAY WITH A SURGE OF DEWPOINTS EXPECTED AT THE COAST BY MID-AFTERNOON AS THE SEA BREEZE PUSHES SLOWLY INLAND. HEAT INDEX VALUES WILL ONCE AGAIN MAKE A RUN FOR 105 DEGREES FOR AREAS ABOUT 10-20 MILES INLAND FROM THE COAST. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... MODELS HAVE TRENDED EVEN MORE DOMINANT WITH EXPANSIVE DEEP LAYERED HIGH PRES EARLY NEXT WEEK THEN CONTINUE THE TREND FOR THE REMAINDER OF THE MEDIUM RANGE. WE LOWERED DIURNAL POPS A BIT ON TUE AS DEEPER MOISTURE LOOKS TO BE DISPLACED FURTHER S WITH A 5940M 500 MB HIGH BUILDING OVER THE TENNESSEE VALLEY REGION EARLY NEXT WEEK. WE TRENDED HIGHER WITH TEMPERATURES IN THIS PATTERN AND NUDGED READINGS UP INTO THE MID 90S MOST AREAS NEXT WEEK WITH UPPER 90S POSSIBLE WELL INLAND. WE COULD GET INTO MARGINAL HEAT ADVISORY CRITERIA AT SOME POINT NEXT WEEK BUT IT/S MUCH TOO EARLY TO GET A HANDLE ON DEW POINT TRENDS. DIURNAL CONVECTION WILL LIKELY BE SPOTTY AND POPS APPEAR TO RUN BELOW CLIMO FOR THE DURATION. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... A LINE OF HEAVY THUNDERSTORMS HAS DEVELOPED EARLY THIS AFTERNOON ACROSS THE CHS TERMINAL...MAINLY WHERE THE SEABREEZE HAS MOVED INTO AN UNSTABLE AIRMASS. WE EXPECT IFR CONDITIONS TO PERSIST THROUGH 1830Z AS THESE STORMS DRIFT SLOWLY NORTHWEST OR DISSIPATE. THE FIRST ACTIVITY FOR SOUTHEAST GA HAS BEGUN TO FIRE NEAR THE SAV TERMINAL. SLIGHTLY WEAKER FORCING INDICATES LESS POTENTIAL FOR PERSISTENT HEAVY RAINFALL BUT WE ADDED MENTION OF POSSIBLE VICINITY THUNDERSTORMS WITH A TEMPO MVFR SHOWER. SOME MID CLOUDS WILL PROBABLY MOVE BACK IN FROM THE EAST OVERNIGHT WHILE A BACKDOOR FRONT SAGS SOUTH INTO THE AREA. A WEAK NE FLOW LATE TONIGHT SHOULD ALLOW FOR MVFR VSBYS WITHIN A FEW HOURS OF DAYBREAK. ALTHOUGH AN ISOLATED RAIN SHOWER COULD TOUCH EITHER TERMINAL OVERNIGHT...THE BEST CHANCE WILL BE AGAIN ON SATURDAY. EXTENDED AVIATION OUTLOOK...LOW PROBABILITIES OF MAINLY DIURNAL CONVECTION AT THE TERMINALS THROUGH SUNDAY. PRE-DAWN WINDS COULD BE N OR NE OVER THE WEEKEND DUE TO A STRAGGLING FRONTAL BOUNDARY...RESULTING IN BRIEF MVFR VSBYS. OTHERWISE...VFR CONDITIONS ARE EXPECTED TO PREVAIL. && .MARINE... VERY BENIGN CONDITIONS WILL PERSIST ACROSS THE MARINE AREA THROUGH SATURDAY MORNING...OUTSIDE OF ANY THUNDERSTORMS. OVERNIGHT SOUTHEASTERLY WINDS WILL SLIGHTLY BACK MORE SOUTHERLY WITH SEAS REMAINING NO MORE THAN 2 FEET. SATURDAY THROUGH TUESDAY...A BROAD SOUTHERLY WIND REGIME WILL PERSIST THROUGH NEXT WEEK WITH SURFACE HIGH PRESSURE POSITIONED WELL OFFSHORE. WINDS LOOK TO REMAIN LESS THAN 10 KT THROUGH THE PERIOD WITH SEAS 2 FT OR LESS. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. &&
