The episode as NWS CAE wrote it up.
An upper level disturbance, a surface boundary and strong diurnal heating led to severe thunderstorms in the afternoon and evening.
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 Columbia, SC wrote its last area forecast discussion before the first event at Jun 17, 5:55 PM EST, 25 minutes earlier.
Area Forecast Discussion National Weather Service Columbia SC 655 PM EDT Fri Jun 17 2022 .SYNOPSIS... Temperatures remain above normal with thunderstorms expected to move into the area late this afternoon and evening as a front moves through the region. Slightly cooler and much drier air will be over the Carolinas through the weekend with a warming trend returning to the area Monday with high temperatures around 100 for Tuesday onward. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... Update...Convection continues to march across the forecast area with cells quickly developing along colliding out flow boundaries. With plenty of instability from diurnal heating and a sea breeze noted on satellite imagery and surface obs expect the convection to continue with potential for severe thunderstorms across much of the central and eastern Midlands as well as the southern CSRA. As such severe thunderstorm watch 385 for Newberry, Fairfield and Lancaster counties will expire at 7 pm. Severe thunderstorm watch 387 for all areas along and east of I-20 and Chesterfield county will go into effect until midnight. Previous discussion...MCS and frontal boundary continue dropping through KY and TN and will move into the forecast area late this afternoon and evening. With temperatures in the mid and upper 90s there is plenty of instability however divergence aloft remains weak. With stronger mid level flow compared to yesterday expect cells to have better forward propagation however with pwat values aoa 2 inches the potential for locally heavy rainfall definitely exists. DCAPE values will also be over 1000 J/Kg and with some mid level dry air noted on WV imagery potential for strong and damaging winds gusts also exists. The front and thunderstorms will generally move east of the forecast area by late this evening however a few cells may develop along any remaining outflow boundaries which intersect. 850 mb winds turn northerly between 06 and 09z which will bring an end to any remaining convective activity. High temperatures will remain in the upper 90s this afternoon with low temperatures tonight in the low to mid 70s. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/... The surface front will be just south of the area by Saturday morning, an should continue to gradually push away from the area through the day as polar high pressure starts pushing in from the Great Lakes region. Low level temps will still be on the warm side, with lower to mid 90s for highs from north to south across the CWA, but the dewpoints will become noticeably drier by afternoon. Of course, while it will certainly feel less oppressive, it is still a near solstice sun angle with plenty of sunshine, so caution should still be used when outdoors for an extended period of time during the heat of the day. Cooler and drier air will continue to push in for the remainder of the weekend as the surface high pressure ridges right into South Carolina. Sundays dew points will be downright springlike by Sunday afternoon with upper 30s to mid 40s, while the temps will remain in the upper 80s to lower 90s, just a bit below normal for a change. Precipitation chances are near zero for the weekend. && .LONG TERM /MONDAY THROUGH FRIDAY/... The heat will be building again next week as the mid and upper ridge become re-established across the southern tier of the U.S. The real question is exactly how hot we will get. The NAEFS shows mean 850 temps 2 to 3 SD above normal, but the EPS shows 3 to 4 SD above normal, which translates to surface temps about 5 to 8 degrees warmer than the NAEFS. So, either we will be slightly seared or fully well done. I think the NBM offers a reasonable compromise this far out given the uncertainty of the ridge strength in the extended. For precipitation chances, it looks very small the first half of the week as we only slowly recover from the dry air over the weekend. By the second half of the week, low level flow becomes more southerly and PWs are back on the rise, so scattered afternoon/evening thunderstorms looks like a good bet. There is also a clustering of ensemble solutions at that time with a weaker eastern end of the upper ridge...opening the door for ridge riders. This also means the max temp forecasts as we get late in the week are a bit more uncertain as convection or its associated cloud debris could modify things. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... Convection and restrictions expected to continue through this evening. Thunderstorms have developed and continue to develop along outflow boundaries across the terminals. With numerous cells and outflows expect thunderstorms to continue for the next several hours...especially in the OGB area where the sea breeze continues pushing inland. The main threat with the thunderstorms remains strong and gusty winds. The front and remaining convection will move south of the terminals overnight with debris cloudiness lingering into the early morning hours which should prevent fog development. With sunrise and mixing winds will become northerly as slightly cooler and much drier air move into the area. EXTENDED AVIATION...No significant impacts to aviation expected through Wednesday. && .CLIMATE... Temperatures will approach record values across the Midlands and Central Savannah River Area again this afternoon. Here are the record high temperatures for both Columbia and Augusta this afternoon. Today: Augusta - 101 degrees in 1944 Columbia - 101 degrees in 2015 & 1944 && .CAE WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None. &&
