The episode as NWS CHS wrote it up.

NWS Charleston, SC wrote its last area forecast discussion before the first event at Aug 10, 6:39 PM EST, 6 minutes earlier.
Area Forecast Discussion National Weather Service Charleston SC 739 PM EDT Wed Aug 10 2022 .SYNOPSIS... High pressure will prevail tonight. A cold front will approach Thursday into Friday, before pushing offshore early Saturday. High pressure will briefly return early next week. Another front could impact the region towards the middle of the week. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... Arcing line of thunderstorms that began in southern Georgia, continues to press north/northeastward into the Georgia counties. Still decent instability across a good part of the CWA...2500-3000 J/Kg, greatest along the coastal counties along and behind the sea breeze. Also a good amount of DCAPE of around 1000 J/Kg as well. Convection has weakened some, but still showing some stronger updrafts, decent wind signatures with a few stations reporting 30 to 40 mph winds as the convection moves through. High-res CAM guidance insists convection will weaken over the next few hours. But of course, will continue to monitor convection as it moves through. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/... A mid level trough will amplify down the East Coast Thursday into Friday. At the surface, high pressure will weaken as a cold front approaches from the northwest. Models are pretty consistent in showing the front passing through the area Friday night into early Saturday. Better forcing and moisture will lead to at least scattered showers and thunderstorms both days, with activity possibly lingering into the overnight period as well. Friday looks the most active with some pockets of heavier rainfall possible. The threat for organized severe weather is low, but couldn't rule out a couple stronger to possibly severe storms. Temperatures near normal in the lower 90s on Thursday will fall a few degrees into the mid to upper 80s for Friday. Lows mainly in the lower 70s Thursday night will be in the upper 60s/low 70s for Friday night. With the front progged to clear the area, Saturday should be quite pleasant for late summer with drier air moving in as high pressure rebuilds. Expect lower rain chances, plenty of sun, and cooler temperatures with highs mainly in the mid 80s. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... A large mid level trough will reside over the eastern half of the country during the early to middle of next week. At the surface, high pressure will prevail, before another front possibly moves into the area. Still some uncertainties on the evolution, but the pattern could favor an increase in rain chances towards the middle of the week. Temperatures will be near to slightly below normal. && .AVIATION /23Z WEDNESDAY THROUGH MONDAY/... Arcing line of showers and storms will move up through the Georgia counties over the next few hours. Might clip the SAV terminal area by 0030Z and I have included VCTS in the 00Z taf forecast accordingly. CHS/JZI appear safe from any convection at this juncture. Additional showers and storms are possible again Thursday afternoon and I have included VCSH in for all three sites. Finally, a good amount of the Saharan Dust has spread off the Atlantic into coastal SC and GA, resulting in a fair amount of haze this afternoon and tonight. JZI is reporting 5sm in haze as a result. Unclear how long the dust layer will be with us. But there may be occasional reduced surface visibilities through Thursday. Extended Aviation Outlook: Prevailing VFR. Brief flight restrictions are possible in afternoon showers/tstorms. && .MARINE... Through this Evening: Expect elevated winds along the land/sea interface as the sea breeze moves inland, especially across the Charleston Harbor. There could also be some showers and thunderstorms with brief, strong wind gusts. Tonight: Our area will be sandwiched between Atlantic High pressure and an inland surface trough. The interaction between these two features will cause a nocturnal jet to develop for the first part of the night with SW winds around 15 kt. These winds should ease a few kt before daybreak Thursday, and veer a little bit in direction. Seas will peak in the 3-4 ft range. Thursday through Monday: Southwest to west winds will prevail through Friday ahead of an approaching cold front. The front will pass offshore late Friday night or Saturday morning, flipping winds around to the northeast/east for much of the weekend. Conditions are expected to stay below small craft advisory criteria. Early next week, winds will return to the south. Seas will average 2 to 3 feet. Rip Currents: There is a Moderate Risk at all of our beaches through this evening. Lingering swell of around 2 feet every 8 seconds and astronomical influences will lead to a Moderate risk of rip currents on Thursday. The threat should decrease for Friday. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None. MARINE...None. && NEAR TERM...TBA SHORT TERM...ETM LONG TERM...ETM AVIATION...ETM/TBA MARINE...ETM
