The episode as NWS CHS wrote it up.
A broken line of scattered thunderstorms developed in the afternoon hours across southeast South Carolina. These storms persisted and moved eastward into the evening with a few storms producing strong wind gusts and frequent lightning.
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 Sep 11, 2:42 PM EST, 2 hours 23 minutes earlier.
Area Forecast Discussion National Weather Service Charleston SC 342 PM EDT Sun Sep 11 2016 .SYNOPSIS... A weakening cold front will approach the area tonight before stalling over or near the area Monday. An area of low pressure should then pass to the south Tuesday into Wednesday bringing with an increase in tropical moisture. A cold front will then approach from the north Thursday into Friday. High pressure will then return next weekend. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... A weak cold front will approach from the northwest late. This could lead to some showers and thunderstorms continuing overnight, especially north and west toward the Midlands/CSRA. Can't rule out an isolated severe storm with damaging winds the rest of the afternoon given DCAPEs near 1000 j/kg. Could see some patchy fog develop late, mainly where clouds thin out which is most likely near the Altamaha. Low temps will mainly be in the lower to mid 70s, warmest nearest the coast. && .SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/... Monday: Surface high pressure building into the northeastern states will help shift winds to a more easterly direction during the day as a weak cold front stalls across the area. Increasing moisture in the mid and upper levels of the atmosphere ahead of a weak upper level low in the northern Gulf of Mexico will help push precipitable water values to around 2 inches. Even though there will be quite a bit of cloud cover, some heating on Monday should result in the development of scattered mainly afternoon showers and thunderstorms, most likely across inland areas in close proximity to the deepest moisture. The slow motion of the convection could result in some heavy rain in some areas. High temperatures will be a good 5 to 7 degrees lower than those from today due to more cloud cover, earlier and greater coverage of convection and an easterly wind off the ocean. The coverage and intensity of the convection will drop off during the evening with the loss of heating. Cannot rule out precipitation at anytime during the night, so maintained at least slight chance, highest near the coast. Tuesday and Wednesday: A weak area of low pressure associated with convection in the southeastern Bahamas is expected to move northwest across Florida Tuesday and into or near the Florida panhandle by Wednesday. A surge of mid and high level moisture associated with the system will move into southern areas Tuesday and possibly spread into other areas Tuesday night and likely persist at least into Wednesday. The remains of the stalled front providing weak forcing combined with surface dew points in the lower to perhaps mid 70s should aid in the development for afternoon showers and/or thunderstorms both Tuesday and Wednesday afternoons and evenings. With precipitable water values likely around 2.25 inches, especially in the south, slow moving or training thunderstorms pose a threat for localized heavy rainfall during the afternoon and evening hours both days. The greatest precipitation coverage is anticipated over southern areas where likely pops are now in the forecast for both Tuesday and Wednesday. A decent amount of cloud cover and precipitation should keep highs mainly in the mid to perhaps upper 80s, with lower 80s near the coast. Lows will be rather warm, mainly in the lower to mid 70s. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... Latest guidance indicates a slightly weaker signal in regards to a wedge type pattern developing east of the Appalachian Mountains during the later half of the week. However, a cold front is still anticipated to approach from the north Thursday into Friday with a slightly cooler airmass within a northeast flow regime. Given this scenario, chances of showers and thunderstorms will be possible along/ahead of a southward advancing front on Thursday, before best chances of precip occur over coastal waters on Friday. A large mid/upper lvl ridge of high pressure is then expected to develop over much of the southern United States this weekend, allowing temps to warm a few degrees into the mid and upper 80s. By Sunday, a southerly flow returns ahead of another front approaching inland areas late. Showers/thunderstorms will be possible starting off next week, but greatest chances should occur well inland near the vicinity of the approaching front. Temps should also warm a degree or two above normal, into the upper 80s away from the coast. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... Generally VFR at both KCHS/KSAV. Small risk of restrictions from showers/thunderstorms ahead of an approaching/stalling cold front, mainly this afternoon and again after daybreak Monday. Also, low clouds and/or fog could impact the terms late tonight, especially at KCHS. However, chances/confidence too low to warrant mentioning at this point. Extended Aviation Outlook: VFR conditions should prevail outside of brief showers or thunderstorms Monday. Flight restrictions will then be possible Tuesday and Wednesday as low pressure tracks just south of the area, especially at the SAV terminal. Additional flight restrictions will be possible Thursday as a cold front approaches from the north with showers and/or thunderstorms. && .MARINE... Tonight: No significant concerns as a weak pressure gradient resides over the region ahead of an approaching weak cold front from the northwest. Winds mainly 10 kt or less with seas 2 ft or less. Monday through Friday: A weak cold front should stall across the coastal waters on Monday. Easterly winds at or below 12 knots will develop on Monday. Seas should be no higher than 2-3 feet. An east/northeast wind should then persist and increase a bit over the waters Tuesday into Wednesday as an area of low pressure tracks across Florida. In general, winds could approach 15 knots or so while seas range from 2 to 4 feet. A cold front should then approach northern waters late Thursday into early Friday with northeast winds that gust as high as 15-20 kt and seas that build up to 3-5 ft. Small Craft Advisory conditions could be possible early weekend. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None. MARINE...None. && SYNOPSIS...
