The episode as NWS CHS wrote it up.
Scattered thunderstorms developed in the mid afternoon hours along the sea breeze within a typical summertime airmass. A few of these storms became strong enough to produce damaging wind gusts.

NWS Charleston, SC wrote its last area forecast discussion before the first event at Jul 5, 2:25 PM EST, 2 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 325 PM EDT SUN JUL 5 2015 .SYNOPSIS... ATLANTIC HIGH PRESSURE WILL PREVAIL WITH AN INLAND TROUGH OF LOW PRESSURE LINGERING THROUGH THE WEEK. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... A CLOSED MID/UPPER LVL LOW NEAR THE OHIO RIVER VALLEY WILL GRADUALLY LIFT NORTHEAST WITHIN A BROAD TROUGH OF LOW PRESSURE EXTENDING ACROSS MUCH OF THE EASTERN CONUS. AT THE SFC...THE AREA WILL REMAIN BETWEEN A WEAK TROUGH INLAND AND HIGH PRESSURE OVER THE WESTERN ATLANTIC. THE PATTERN WILL SUPPORT DEEP MOISTURE ADVECTION TO THE SOUTHEASTERN UNITED STATES WITHIN A SOUTHWEST FLOW...SETTING UP FAVORABLE CONDITIONS FOR AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS. LATE THIS AFTERNOON INTO EARLY EVENING...SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE FOR MOST AREAS AS THE LEADING EDGE OF A H5 SHORTWAVE ROUNDS THE SOUTHERN EDGE OF THE MID/UPPER LOW CENTERED OVER NORTHWESTERN KENTUCKY. DEEP MOISTURE LEVELS CHARACTERIZED BY PWATS NEAR 1.9 INCHES ALONG WITH SUFFICIENT SFC HEATING...WILL CONTINUE TO SUPPORT A MODERATELY UNSTABLE ENVIRONMENT THIS AFTERNOON AND EVENING OVER PARTS OF SOUTHEAST SOUTH CAROLINA AND SOUTHEAST GEORGIA. LATEST RADAR IMAGERY INDICATES SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS ALONG THE I-95 CORRIDOR AHEAD OF A SMALL COMPLEX OF THUNDERSTORMS SHIFTING EASTWARD OVER PARTS OF SOUTHEAST GEORGIA. WE HAVE SEEN SOME STABILIZATION DUE TO ONGOING CONVECTION OVER THE LAST 1-2 HOURS...BUT OUTFLOWS FROM PREVIOUS CONVECTION ALONG WITH AREAS THAT ARE STILL SEEING SUN SHOULD HELP INITIATE AND/OR STRENGTHEN SOME THUNDERSTORMS LATE AFTERNOON INTO EARLY EVENING HOURS...PARTICULARLY OVER SOUTHEAST GEORGIA WHERE SBCAPES RANGE BETWEEN 2500-3000 J/KG. DCAPES RANGING BETWEEN 800-1000 J/KG ALONG WITH INVERTED V MODEL SOUNDINGS SUGGEST THUNDERSTORMS CAPABLE OF PRODUCING STRONG AND/OR DAMAGING WIND GUSTS. LIKE PREVIOUS DAYS...A FEW THUNDERSTORMS COULD BECOME SEVERE UNTIL DIURNAL HEATING IS LOST WITH SUNSET. GIVEN THIS POTENTIAL...THE STORM PREDICTION CENTER HAS ALSO PLACED THE ENTIRE AREA IN A MARGINAL RISK FOR SEVERE STORMS TODAY. LATE THIS EVENING AND OVERNIGHT...A CHANCE FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE DURING LATE EVENING AND EARLY OVERNIGHT HOURS AS MID LVL SHORTWAVE ACTIVITY SHIFTS NEAR/OFF THE SOUTHEAST COAST. ALTHOUGH THE SEVERE THREAT WILL DIMINISH WITHIN AN HOUR OR TWO OF SUNSET...THE POTENTIAL EXISTS FOR A FEW STRONGER STORMS CAPABLE OF PRODUCING GUSTY WINDS. THE FOCUS FOR CONVECTION SHOULD THEN SHIFT OFFSHORE INTO THE NEARBY ATLANTIC LATE TONIGHT WHERE INSTABILITY WILL BE GREATEST. LOW TEMPS SHOULD RANGE IN THE LOW TO MID 70S. && .SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/... OVERVIEW: UPPER LEVEL LOW PRESSURE WILL WEAKEN AND EJECT OUT OF THE TENNESSEE VALLEY EARLY TUESDAY. A POTENT MULTI-LAYER RIDGE WILL BUILD WEST AND EXTEND ACROSS THE REGION THROUGH MID WEEK. THIS WILL YIELD A RETURN TO A MORE STANDARD EARLY SUMMER CONVECTIVE REGIME ACROSS SOUTHEAST SOUTH CAROLINA AND SOUTHEAST GEORGIA. MONDAY: MONDAY LOOKS TO BE THE MOST ACTIVE DAY OF THE MID-RANGE PERIOD AS UPPER LEVEL LOW PRESSURE WEAKENS AND EJECTS OUT OF THE TENNESSEE VALLEY IN RESPONSE TO STRONG SHORTWAVE ENERGY PIVOTING ACROSS THE WESTERN GREAT LAKES. MODELS SHOW A DEEP 500 HPA TROUGH LINGERING ACROSS THE DEEP SOUTH IN THE WAKE OF THE DEPARTING LOW AS A LARGE...UPPER RIDGE REMAINS POSITIONED OFFSHORE OF THE SOUTHEAST U.S. COAST. THE COMBINATION OF SUFFICIENT LEVELS OF MOISTURE... INSTABILITY AND LIFT WILL SUPPORT ANOTHER ROUND OF MAINLY AFTERNOON AND EVENING SHOWERS/TSTMS. IN ADDITION...THERE ARE SIGNALS THAT AN ENHANCED AREA OF UPPER DIFLUENCE COULD DEVELOP OVER THE AREA DURING THE AFTERNOON AS THE RIGHT ENTRANCE REGION OF A SUBTROPICAL JET STREAK MEANDERS EAST/NORTHEAST IN RESPONSE TO THE EJECTION OF THE UPPER LOW. WILL HIGHLIGHT 50-60 PERCENT POPS. FORECAST SOUNDINGS YIELD A BIT LESS IN THE WAY OF INSTABILITY COMPARED TO THE PAST SEVERAL DAYS WITH SLIGHTLY LOWER MLCAPE AND DCAPE...BUT LEVELS ARE STILL SUFFICIENT TO SUPPORT A FEW STRONG/SEVERE TSTMS...MAINLY ALONG MESOSCALE BOUNDARY COLLISIONS. CONVECTION WILL WANE DURING THE EVENING HOURS AS THE AXIS OF STRONGEST LOW-LEVEL CONVERGENCE REDEVELOPS ALONG THE WESTERN WALL OF THE GULF STREAM AFTER MIDNIGHT. HIGHS WILL TOP OUT IN THE LOWER 90S INLAND WITH LOWS RANGING FROM THE LOWER-MID 70S INLAND TO THE UPPER 70S ALONG THE BEACHES AND DOWNTOWN CHARLESTON. TUESDAY AND WEDNESDAY...MEAN RIDGING WILL BUILD WEST THROUGH THE PERIOD WITH THE REGION REMAINING ALONG THE WESTERN FRINGE OF ATLANTIC HIGH PRESSURE. SHOWERS AND TSTMS ARE POSSIBLE EACH AFTERNOON AND EVENING...BUT COVERAGE WILL BE LIMITED BY WARMING TEMPERATURES ALOFT AND SOME SYNOPTIC SUBSIDENCE ASSOCIATED WITH THE UPPER RIDGE. INSTABILITY AND MOISTURE STILL LOOK PLENTIFUL...WHICH SHOULD BE SUFFICIENT TO SUPPORT ISOLATED TO PERHAPS LOW-END SCATTERED CONVECTION ALONG/AHEAD OF THE RESULTANT SEA BREEZE CIRCULATION AS WELL AS A PERSISTENT PIEDMONT TROUGH. 20-30 PERCENT POPS LOOK REASONABLE EACH AFTERNOON AND EVENING. HIGHS WILL WARM INTO THE LOWER-MID 90S WITH LOWS RANGING FROM THE LOWER-MID 70S INLAND WITH UPPER 70S AT THE BEACHES AND DOWNTOWN CHARLESTON. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... MEDIUM RANGE GUIDANCE IS IN FAIRLY GOOD AGREEMENT INDICATING HIGH PRESSURE DOMINATING THROUGH AT LEAST FRIDAY...THEN THERE IS MORE DISCREPANCY/FORECAST UNCERTAINTY REGARDING HOW QUICKLY THE RIDGE BREAKS DOWN LATE WEEK AND OVER THE WEEKEND. EXPECT LOW SHOWER AND THUNDERSTORM COVERAGE THROUGH THE PERIOD...MAINLY EACH AFTERNOON/EVENING. TEMPERATURES WILL LIKELY BE A BIT WARMER THAN NORMAL WITH HIGHS IN THE MID 90S AWAY FROM THE COAST AND LOWS IN THE MID 70S INLAND AND MID TO UPPER 70S AT THE COAST. THE COMBINATION OF SUCH TEMPS AND THE HUMIDITY LEVELS SHOULD RESULT IN HEAT INDEX VALUES AT OR ABOVE 100 DEGREES. && .AVIATION /20Z SUNDAY THROUGH FRIDAY/... SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS ARE EXPECTED DURING THE LATE AFTERNOON AND EARLY EVENING AT BOTH CHS AND SAV TERMINALS. HAVE MAINTAINED A TEMPO GROUP FROM 18-22Z AT CHS AND 19-21Z AT SAV FOR THUNDERSTORMS CAPABLE OF PRODUCING FLIGHT RESTRICTIONS AND GUSTY/ERRATIC WINDS. CONDITIONS WILL LIKELY IMPROVE NEAR SUNSET THIS EVENING. VFR CONDITIONS SHOULD PREVAIL AT BOTH TERMINALS EARLY TONIGHT THROUGH 18Z MONDAY. EXTENDED AVIATION OUTLOOK...BRIEF FLIGHT RESTRICTIONS ARE POSSIBLE IN MAINLY AFTERNOON/EARLY EVENING SHOWERS AND THUNDERSTORMS...WITH THE BEST CHANCES MONDAY. && .MARINE... THIS EVENING AND TONIGHT...CONDITIONS ARE EXPECTED TO REMAIN BELOW SMALL CRAFT ADVISORY LEVELS THROUGH THE PERIOD. SOUTH TO SOUTHWEST WINDS WILL PREVAIL OVER THE WATERS BETWEEN ATLANTIC HIGH PRESSURE CENTERED WELL OFFSHORE AND A TROUGH OF LOW PRESSURE NORTHWEST OF THE AREA. WIND SPEEDS SHOULD GENERALLY REMAIN AT OR BELOW 15 KTS...BUT LOCAL ENHANCEMENT IS POSSIBLE LATER THIS EVENING INTO THE OVERNIGHT PERIOD DUE TO NOCTURNAL SURGING. SEAS SHOULD REMAIN 2-3 FT ACROSS THE WATERS. WINDS AND SEAS COULD VARY WITH A FEW SHOWERS AND/OR THUNDERSTORMS THAT SHIFT OFFSHORE LATE EVENING INTO EARLY TONIGHT. MONDAY THROUGH FRIDAY...SOUTH TO SOUTHWEST WINDS WILL PREVAIL THROUGH THE PERIOD AS THE REGION REMAINS ALONG THE WESTERN FRINGE OF ATLANTIC HIGH PRESSURE CENTERED WELL OFFSHORE. WINDS WILL GENERALLY AVERAGE 10-15 KT...POSSIBLY A BIT HIGHER AT NIGHT WITH WEAK NOCTURNAL SURGING AND ALONG THE LAND/SEA INTERFACE WITH THE AFTERNOON SEA BREEZE. SEAS WILL AVERAGE 2-4 FT. BOTH WINDS AND SEAS LOOK TO REMAIN BELOW SMALL CRAFT ADVISORY THRESHOLDS. RIP CURRENTS...THE COMBINATION OF LINGERING LUNAR INFLUENCES...AN EASTERLY SWELL OF 2 FT EVERY 8-9 SECONDS AND GUSTY WINDS WILL SUPPORT A MODERATE RISK FOR RIP CURRENTS FOR THE LOWER SOUTH CAROLINA BEACHES INTO THIS EVENING. && .CHS WATCHES/WARNINGS/ADVISORIES...
