The episode as NWS RLX wrote it up.
Isolated to scattered showers and thunderstorms developed on the afternoon of August 19th in southwest Virginia. Locally heavy rainfall resulted in one instance of high water issues along Dante Mountain Road in Dickenson County through the early evening hours.
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, WV wrote its last area forecast discussion before the first event at Aug 19, 1:21 PM EST, 3 hours 19 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Charleston WV 221 PM EDT Fri Aug 19 2022 .SYNOPSIS... Upper disturbance crosses tonight and Saturday, followed by another one thru Sunday and Monday. && .NEAR TERM /THROUGH SATURDAY/... As of 145 PM Friday... Isolated to widely scattered showers and thundershowers will continue to develop along the mountain ridges this afternoon on weak low level convergence. These will initially be slow movers before a few of these try drift into the lowlands toward evening. I left a low POP in overnight as there will be a weak s/w trof crossing which may spark a shower or two. Otherwise some mid deck will drift across the mountains with river valley fog setting up once again across the area. Low temperatures should be similar to the past few evenings, perhaps a few degrees warmer in the mountains. Weak PVA will serve as the primary focus for showers and thundershowers Saturday, maximized by daytime heating. In addition, light southeast flow will aid in afternoon mountain activity. High temperatures will top out a few degrees above normal. && .SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/... As of 217 PM Friday... Models show a strong upper-level low pressure system tracking east into the Great Lakes region Saturday night, becoming an open but sharp trough with axis extending to our west by Sunday, as it moves southeast into the OH Valley. Weak ripples of vorticity will move over the area to provide some upper-level forcing during this time. Meanwhile, deep low-level south southwest flow will bring enough moisture, bringing PWATs to 1.5 inches, and theta-e values up to 338K needed to allow for scattered showers and isolated thunderstorms to develop under weak upper level forcing. Therefore, expect some convection during the afternoon and evenings across the lowlands, with additional showers/storms possible along the eastern mountains Saturday night into Sunday. By Sunday and Sunday night, the upper trough axis remains to our west, but stronger vorticity maxima move over the area increasing chances for stronger convection. At this time, a cold front approaches from the northwest, but stalls and lift quickly north as a warm front instead of affecting the area directly. Any storm at this point will be sub-severe, although SPC painted the western half of our CWA under a marginal risk of severe thunderstorms Sunday and Sunday night. Will keep monitoring the latest guidance in case severe risk increases. && .LONG TERM /MONDAY THROUGH FRIDAY/... As of 217 PM Friday... Good chances for showers and storms to continue Monday and Monday night as the axis of the aforementioned upper trough crosses east with additional pieces of energy, and a new cold front pushes southeast Monday night. Depending of the antecedent precipitation, soils will be vulnerable to reach saturation in a shorter period of time. Will have to monitor conditions closely ahead of possible water issues. Guidance shows surface high pressure building across the OH Valley into WV from late Tuesday through the end of the week, providing drier weather conditions. Near normal temperatures expected Monday and Tuesday with abundant cloudiness and scattered showers. Then, a slight warm up is expected Wednesday through the end of the week under mostly sunny skies. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... As of 150 PM Friday... Isolated to widely scattered SHRA with perhaps a rumble of thunder will dot the mountain ridges through the remainder of the afternoon. Kept a VCTS for BKW and VCSH at EKN this afternoon. A few of these may try to sneak into the lowlands toward evening, but confidence too low to make any mention at CRW or CKB. Some mid deck will cross the mountains tonight, perhaps delaying river valley fog at EKN a few hours from previous nights. Otherwise, IFR or worse fog will affect the terminals, save for BKW. Any fog will quickly dissipate after 12Z for VFR conditions for the remainder of the TAF period. A few SHRA with perhaps some thunder will be noted across the area from late morning onward. Elected to keep the TAFs clean through 18Z with this issuance though. Surface flow will be light and generally out of the south or southeast. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z SATURDAY... FORECAST CONFIDENCE: High. ALTERNATE SCENARIOS: Onset timing and intensity of fog may vary from forecast tonight.

miles northwest of Glen Burke, or 9 miles east of Grundy, moving
northeast at 20 mph.
HAZARD...Winds in excess of 30 mph.
SOURCE...Radar indicated.
IMPACT...Gusty winds could knock down tree limbs and blow around
unsecured objects.
Locations impacted include...
War, Bradshaw, Iaeger, Avondale, Jolo and Oakwood.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
If outdoors, consider seeking shelter inside a building.
Torrential rainfall is also occurring with this storm and may lead to
localized flooding. Do not drive your vehicle through flooded
roadways.
Frequent cloud to ground lightning is occurring with this storm.
Lightning can strike 10 miles away from a thunderstorm. Seek a safe
shelter inside a building or vehicle.
This storm may intensify, so be certain to monitor local radio
stations and available television stations for additional information
and possible warnings from the National Weather Service.
In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to travel across
flooded roads. Find alternate routes. It takes only a few inches of
swiftly flowing water to carry vehicles away.
Do not drive your vehicle into areas where the water covers the
roadway. The water depth may be too great to allow your car to cross
safely. Move to higher ground.
