The episode as NWS CHS wrote it up.
Scattered to numerous thunderstorms developed starting in the early afternoon hours and produced damaging wind gusts across southeast Georgia before pushing off the coast. The storms developed within northwest flow aloft with local enhancements provided by mesoscale boundary interactions. Several of the storms became severe and produced damaging wind gusts.

NWS Charleston, SC wrote its last area forecast discussion before the first event at Jul 19, 9:38 AM EST, 4 hours 31 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 1038 AM EDT SUN JUL 19 2015 .SYNOPSIS... AN INLAND SURFACE TROUGH WILL PERSIST THROUGH TUESDAY. A WEAK COLD FRONT COULD APPROACH FROM THE NORTH ON WEDNESDAY AND THEN LINGER THROUGH LATE WEEK. && .NEAR TERM /THROUGH TONIGHT/... THE EXPANSIVE ANTICYCLONE CENTERED OVER THE SOUTHERN GREAT PLAINS AND LOWER MS VALLEY WILL WEAKEN A BIT ON ITS NE AND E FLANKS TODAY JUST ENOUGH TO ALLOW WEAK PERTURBATIONS IN NW TO N FLOW ALOFT TO BRUSH THE FORECAST AREA. 00Z MODEL GUIDANCE INDICATES AN EARLY MORNING CAP RANGING FROM 4C ACROSS COASTAL SOUTH CAROLINA TO ABOUT 2C-3C ACROSS SE GEORGIA. TYPICAL MID/LATE JULY THERMODYNAMIC PROFILES PROGGED THIS AFTERNOON WITH A LEE-SIDE SURFACE TROUGH EXTENDING INTO THE MIDLANDS AND CSRA REGION. THIN CLOUDS WILL DO LITTLE TO HINDER STRONG SURFACE HEATING THIS MORNING WITH TEMPS REACHING THE LOW TO MID 90S BY EARLY AFTERNOON. HIGH TEMPS IN THE MID 90S MANY AREAS WITH MAX HEAT INDEX VALUES AROUND 105 THIS AFTERNOON. MODEL CONSENSUS SUGGESTS THE BETTER MID LEVEL ENVIRONMENT ALONG WITH GREATER 850MB-500MB MOISTURE PROFILES WILL BE ALONG AND W OF I-95 UNDER RIPPLES OF WEAK UPPER DIFLUENCE. SCATTERED SHOWERS AND TSTMS WITH PULSE/MULTICELL MODES SHOULD DEVELOP AFTER MID AFTERNOON WITH STORM PROPAGATIONS NNW-SSE OR DOWN THE SEA-BREEZE. WE BUMPED POPS TO 40 PERCENT ACROSS INLAND SE GEORGIA GIVEN LATEST TRENDS. DIURNAL CONVECTION COULD BE MORE ISOLATED FURTHER NE INTO THE CHARLESTON TRI-COUNTY AREA HOWEVER WITH A SLOWER MOVING RESULTANT SEA BREEZE WE MAINTAINED LOW END CHANCE POPS ALONG CENTRAL COASTAL SOUTH CAROLINA. DIURNAL CONVECTION SHOULD DIMINISH THIS EVENING AS IS TYPICAL THIS TIME OF YEAR WITH ONLY ISOLATED POTENTIAL OVERNIGHT AT BEST. WARM AND MUGGY CONDITIONS WITH OVERNIGHT READINGS MID TO UPPER 70S ONCE AGAIN. && .SHORT TERM /MONDAY THROUGH WEDNESDAY/... FOR THE MONDAY THROUGH WEDNESDAY TIME PERIOD...THE FIRST COUPLE OF DAYS WILL PRIMARILY BE DRIVEN BY THE PERSISTENT SURFACE TROUGH AND THE GRADUALLY WEAKENING INFLUENCE OF THE UPPER RIDGE CENTERED TO THE WEST. IN FACT BY WEDNESDAY...A WEAK FRONT WILL SINK SOUTHWARD AND INTO THE VICINITY OF THE FORECAST AREA. THIS WILL TAKE PLACE AS ZONAL FLOW ALOFT BECOMES MORE CYCLONIC THROUGH THE DAY. SO...THE OVERALL TREND WILL BE FOR INCREASING DIURNAL POPS EACH DAY TO ACCOUNT FOR THE ATMOSPHERE BECOMING MORE SUPPORTIVE OF SHOWERS/THUNDERSTORM DEVELOPMENT. THE OVERALL SEVERE THREAT LOOKS TO BE QUITE MARGINAL...BUT DEPENDING ON HOW MESOSCALE OUTFLOW BOUNDARIES EVOLVE AND INTERACT THERE COULD BE A FEW STRONG TO SEVERE STORMS EACH AFTERNOON/EVENING. IT WILL BE A WARM STRETCH OF DAYS...WITH HIGHS REACHING THE MID/UPPER 90S EACH AFTERNOON. THIS WILL RESULT IN HEAT INDEX VALUES UP TO AROUND 110 ESPECIALLY MONDAY AND TUESDAY. WILL MAINTAIN THE CURRENT WORDING IN THE HWO FOR POSSIBLY NEEDING HEAT ADVISORIES. && .LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... FOR THE LONG TERM PERIOD...THE PATTERN WILL CONTINUE TO TREND TOWARD BECOMING MORE ACTIVE AS THE FLOW ALOFT BECOMES INCREASINGLY CYCLONIC THANKS TO A EASTERN CONUS TROUGH. THE MID WEEK FRONT WILL BECOME NEARLY STATIONARY AND LAY ACROSS THE REGION THROUGH LATE WEEK. THIS WILL LEAD TO AN INCREASINGLY ACTIVE PERIOD AS WAVES DEVELOP ALONG THE BOUNDARY. PERIODS OF HIGHER POPS ARE EXPECTED...ESPECIALLY DURING DIURNAL HEATING...BUT WE COULD EVEN SEE ACTIVITY LINGER THROUGH THE OVERNIGHT PERIODS AT TIMES. CONFIDENCE IN WHICH TIME PERIODS WILL BE MOST ACTIVE IS LOW AT THIS POINT...BUT THE GENERAL CONSENSUS IS FOR INCREASING POPS AND TEMPERATURES DECREASING A BIT CLOSER TO CLIMO NORMALS. && .AVIATION /15Z SUNDAY THROUGH THURSDAY/... VFR CONDITIONS WILL PREVAIL THROUGH 12Z MONDAY. DIURNAL CONVECTION IS POSSIBLE AT THE TERMINALS THIS AFTERNOON AND EVENING. 06Z MODELS CONTINUE TO DIFFER ON BOTH CONVECTIVE INITIATION/LOCATION/TIMING AND WE WILL KEEP TSRA/CB OUT OF THE TAFS THIS MORNING UNTIL 12Z SOUNDING DATA BECOMES AVAILABLE. EXTENDED AVIATION OUTLOOK...LOW END CHANCES FOR DIRECT IMPACTS FROM AFTERNOON/EVENING THUNDERSTORMS EACH DAY. && .MARINE... A SW SYNOPTIC FLOW OVER THE WATERS THROUGH TONIGHT. SPEEDS TONIGHT MAINLY LESS THAN 10 KT UNTIL LATE AFTERNOON. AN UPTICK IN FLOW TONIGHT BUT ONLY 10-15 KT WELL OFFSHORE. SEAS AROUND 2 FT TODAY BUILDING TO 2-3 FT BEYOND 20 NM TONIGHT. MONDAY THROUGH FRIDAY...AN INLAND TROUGH OF LOW PRESSURE WILL BE PRESENT THROUGH WEDNESDAY AND WILL HELP TO DRIVE SOUTHWEST FLOW ACROSS THE LOCAL WATERS. WINDS WILL GENERALLY TOP OUT IN THE 15-20 KT RANGE DURING THIS TIME PERIOD...THOUGH WE COULD SEE SOME 25 KT GUSTS ON TUESDAY WHEN THE PRESSURE GRADIENT IS EXPECTED TO BE TIGHTEST. TYPICAL ENHANCEMENTS WILL TAKE PLACE ALONG THE LAND/SEA INTERFACE EACH AFTERNOON AND EVENING WITH THE SEA BREEZE. THEN BY THURSDAY AND FRIDAY THE OVERALL FLOW PATTERN WILL BECOME LESS CERTAIN AS A FRONT SINKS INTO THE VICINITY FROM THE NORTH. WINDS WILL BECOME A BIT MORE VARIABLE AT TIMES THOUGH WILL BE WEAKER THAN EARLIER IN THE WEEK. SEAS WILL FLUCTUATE IN ASSOCIATED WITH PERIODS OF STRONGER WINDS...BUT WILL GENERALLY RANGE FROM 2-3 FT WITHIN 20 NM AND 3-4 FT BEYOND. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE.
