The episode as NWS CHS wrote it up.
Thunderstorms developed in the early afternoon hours within a warm and moist summertime atmosphere. Most of the thunderstorm activity was concentrated along the coast near convergence associated with the sea breeze. A few of the thunderstorms became severe and produced damaging wind gusts.

NWS Charleston, SC wrote its last area forecast discussion before the first event at Jul 14, 10:00 AM EST, 2 hours 8 minutes earlier.
Area Forecast Discussion National Weather Service Charleston SC 1100 AM EDT THU JUL 14 2016 .SYNOPSIS... Atlantic high pressure will extend west over the region through the first part of next week while a low pressure trough lingers inland across the Carolinas. && .NEAR TERM /THROUGH TONIGHT/... Late this morning: No significant change to the previous forecast thinking for the rest of the day. Aloft, the forecast area is situated between the ridge over the Atlantic and the southern stream upper low along the Gulf coast. There is some mid/upper level energy just to the west noted in water vapor imagery, but its certainly not very significant. At the surface, the lee trough remains the main feature and the afternoon sea breeze will provide another source of low level convergence. Looking at the 12z sounding and comparing it to 24 hours ago, mid level lapse rates aren't as steep and the 500 mb temp is about 2.5 degrees C warmer. Convective temperatures are around 97, and CAPE is a bit less than yesterday as well. Hi-res model runs seem to primarily place convection along the coast with the sea breeze with not a whole lot of inland push. This continues to look like the most likely scenario and pops have been tweaked to mainly favor the sea breeze coastal locations. Heat index values should top out in the 104-107 range, so no heat advisory will be needed. Tonight: Any lingering convection will dissipate with the loss of heating. Warm and humid conditions will persist with lows ranging from the mid to upper 70s inland and the lower 80s at the coast. && .SHORT TERM /FRIDAY THROUGH SUNDAY/... Deep layered subtropical high pres will continue to extend west over the region through the period. On Friday, we continued to nudge pops up during the afternoon and evening hours as models show 2 inch plus pwats expanding across southeast Georgia and eastern South Carolina. Scattered mainly diurnal convection is expected to continue over the weekend with models indicating the best coverage may likely end up across South Carolina on Saturday afternoon as a mid level short wave brushes the nw periphery of the ridge across the southern mid Atlc region. On Sunday, not much change to the pattern with diurnal enhancements to surface moisture convergence and instability progs indicative of a typical mid July day where scattered showers and storms develop by afternoon with pops in the 40 percent range. Ample deep layered instability each day and fairly light steering flow will result in pulse and occasional multi-cell convective modes. Isolated severe tstms possible each day with wet microbursts the main culprit for localized damaging winds. Temps will remain above climo but better coverage of diurnal convection should keep readings from rising above the mid 90s. Lows will be in the mid to upper 70s most locations. && .LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/... On Monday and Tuesday, an extensive upper ridge will blanket the southeast U.S. making way for a continuation of hot and humid weather with scattered diurnal convection after high temps reach the mid 90s each day. During mid week, global models in good agreement that a break in the upper ridge will increase as troughing develops to the north. This should result in temps closer to climo values but little change from the typical day to day chances for scattered mainly diurnal convection. && .AVIATION /15Z THURSDAY THROUGH MONDAY/... VFR will prevail at both KCHS and KSAV through the early afternoon. There is a low chance of flight restrictions 18Z-23Z due to showers and/or thunderstorms, but until radar trends dictate, the potential is too uncertain for TAF inclusions. Extended Aviation Outlook: Brief flight restrictions possible, mainly each afternoon/evening due to showers and thunderstorms into early next week. && .MARINE... Atlantic high pressure will prevail along with an inland surface trough. This pattern will favor south to southwest winds that will provide nocturnal surges Friday and Saturday Nights to near 20 kt at times with some higher gusts. Seas could build to near 4 ft during the evening and overnight hours but ebb to 2 to 3 ft during the morning hours as typically occurs during this persistent summer pattern. The flow is expected to weaken a bit later in the weekend into early next week as directions become a more se to s instead of sw to s. Speeds will be 15 kt or less and seas 3 ft or less Sunday into early next week. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None. MARINE...None. && NEAR TERM...BSH SHORT TERM...
