The episode as NWS RLX wrote it up.
A slow moving cold front approached the Ohio Valley from the north on August 30th combined with a weak upper level disturbance. Increasing moisture in response to the advancement of the remnants of Hurricane Ida allowed for showers and thunderstorms to develop across the area throughout the day. Many of these storms were slow moving and produced heavy downpours that led to flash flooding in southeast Ohio. In Lawrence County, high water flowed into a few commercial buildings.

NWS Charleston, WV wrote its last area forecast discussion before the first event at Aug 30, 1:57 PM EST, 2 hours 18 minutes earlier.
AREA FORECAST DISCUSSION
National Weather Service Charleston WV
257 PM EDT Mon Aug 30 2021
.SYNOPSIS...
Scattered to numerous showers and thunderstorms possible into
Tuesday. Remnants of Ida arrive Tuesday night into Wednesday
with heavy rain/high water. Dry for the holiday weekend.
&&
.NEAR TERM /THROUGH TUESDAY/...
As of 130 PM Monday...
The potential for thunderstorms will continue into tonight and
even through the morning although activity will likely decrease
and be more likely confined across the southern half of our CWA
while the trough ahead of the frontal boundary to the northwest
pushes though. With not a whole of shear available, storms will
generally be sub-severe, however they will pose the threat
of possible flash flooding. Within any storm this threat will
be on the table as moisture available becomes anomalously higher
than the climatological norm. Not to mention the fact that the
area has been getting primed fairly well today and even from
yesterday with several flash flood warnings already seen. A
front draped across the region to the northwest will then try
and make some progress overnight into the morning, however will
be delayed in movement from the remnants of Ida intercepting
in its path.
Rainfall from Ida will start to spread in from the southwest by
early Tuesday afternoon and will continue to slowly, but
progressively increase in intensity through the late evening.
The flood watch will go into effect at 2pm Tuesday and continue
into the next period as Ida makes its way through the area.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
As of 255 PM Monday...
...Remnants of Ida Bring Potential Flash Flooding...
The remnants of Ida will continue to move through the area
Tuesday night through Wednesday night with moderate to heavy
rainfall across the area through much of this period.
A cold front will be pushing southward through the area
simultaneously as Ida moves up from the southwest. The center of
the Ida's remnants is fairly locked in between the models with
moving it through West Virginia or slightly more on the
south/southeastern side of West Virginia as it heads toward
through the area and to the northeast. The center is expected to
creep into the area sometime Wednesday morning and move out
Wednesday night. As Ida's remnants move into the area, the cold
front will push back to the north and become more stationary as
the two interact. As the interaction of the front and Ida
occurs, this will likely be when the heaviest of the rainfall is
expected, around Tuesday night into Wednesday morning.
A Flash Flood Watch is in effect from Tuesday afternoon through
Wednesday afternoon, timing up with when this heavier rainfall
is expected and when most flash flooding issues are expected to
occur for the area. Forecast rainfall amounts are around 2 up to
over 4 inches are expected through Wednesday night with
localized higher amounts possible. There is a moderate risk for
excessive rainfall along the northeast KY and southwest VA
counties as well as portions of southeast OH and WV through
Tuesday night. For Wednesday, much of WV is under a moderate
risk for excessive rainfall. These areas will be the most likely
areas to experience flooding issues, however other flash
flooding issues can't be ruled out for the remainder of the
area.
In addition to main threat of flash flooding with this event,
there will be a possibility for a few tornadoes to form along
Ida's eastern flank of the rain bands. The SPC has a marginal
risk for severe weather right along the eastern edge of the
area for portions of southwest VA and very southeastern WV where
the greatest potential for any tornadic storms associated with
Ida's remnants should be. Gusty winds could also be possible
with any thunderstorms associated with Ida's remnants.
The remnants will finish moving out on Thursday as upper level
ridging approaches from the west.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
As of 115 PM Monday...
Upper level ridging approaches from the west to start the long
term period as the remnants of Ida move off to the
east/northeast on Thursday. At the surface, high pressure also
moves in which will give way to a drier end of the week and
start to the weekend. Upper flow begins to flatten out around
Sunday as a disturbance approaches the area to start the new
week. This may allow for the chance for showers and
thunderstorms Sunday and Monday.
Temperatures are expected to start out slightly below normal,
warming up gradually to around normal by the weekend.
&&
.AVIATION /19Z MONDAY THROUGH SATURDAY/...
As of 140 PM Monday...
Anticipate possible convection going into the late evening for
the southern terminals and possibly EKN. The northern terminals
should be spared, but will start to see MVFR CIGs around
midnight. After convection slows down, all terminals will likely
experience lower VIS/CIGs as fog from saturated grounds develop
and bring down flight categories to around IFR or worse through
the late morning. This will persist through 13Z, where at which
point low CIGs and possible rain showers will continue into the
afternoon along with more possible convection.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z TUESDAY...
FORECAST CONFIDENCE: Medium.
ALTERNATE SCENARIOS: Coverage of convection this afternoon/evening
may vary from the TAFs.
