Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Greensboro/Hi Pt, NC (KGSO), launched 00:00Z, 3.7 hours before the alert went out and 233 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Morristown, TN wrote its last area forecast discussion before this flash flood warning went out at Aug 14, 9:31 PM EDT, 2 hours 13 minutes earlier.
Area forecast discussion, Aug 14, 9:31 PM EDT, 2 hours 13 minutes before
AREA FORECAST DISCUSSION National Weather Service Morristown TN 931 PM EDT Sun Aug 14 2022 .UPDATE... EVENING UPDATE. && .DISCUSSION... Bulk of the convection has been across the north as expected, but a few shoewrs have developed further south. Will update PoPs/Wx to expand precip chances further south with this update. Otherwise, the forecast generally looks to be on track so just some minor tweaks to temps and dew points. && .AVIATION... 00Z TAF DISCUSSION. Some convection around at times especially TRI. Will include VCSH and a tempo group for showers there for tonight, and include VCTS there during the late morning/afternoon on Monday. Elsewhere probability looks too low to include. Outside of any convection expect mainly VFR conditions. However one exception is some fog and/or lower cigs look likely at TRI late tonight/early Monday, so will take conditions to MVFR there for several hours. && .PREV DISCUSSION... /ISSUED 322 PM EDT Sun Aug 14 2022/ SHORT TERM (Tonight and Monday)... Northwesterly flow aloft will provide some disturbances that will provide occasional convection to our SW VA, NE TN, and far eastern mountains tonight and Monday. In tandem, a surface low pressure area will move from Louisville KY this evening southeastward to the VA/KY border Monday morning before moving into the Carolinas. It will be interesting to see if a boundary associated with this low helps focus any heavier precip over the far northeastern corner of our forecast area on Monday as suggested by NAM QPF alone. Temps look to be seasonable most areas, particularly the southern two-thirds of the area. GC LONG TERM (Monday Night through Sunday)... Key Messages: 1. Afternoon showers and thunderstorms possible each day, the best coverage and intensity expected Wednesday and Friday into Sunday as upper level disturbances move through. 2. Temperatures will be several degrees below normal especially during the day, with more comfortable humidity. Discussion: Active pattern continues during the long term period, plenty of chances for rain and temperatures below normal. Upper trough or closed low stays over the eastern states to the north and northeast of the forecast area. Upper level ridging will rule the western states and southern plains Monday night through early Wednesday. From later Wednesday through Saturday the eastern trough expands westward some and the trough deepens over the Mississippi and Tennessee Valleys. Sunday the upper trough begins to shift back northeast as ridging strengthens over the southern plains. A continued chance of mostly diurnally driven showers and some thunderstorms will occur each day, with enhanced rain chances and thunderstorms Wednesday into Wednesday evening and Friday through Sunday. Wednesday a shortwave moving through the NW flow should trigger a round of showers and thunderstorms across Tennessee by afternoon and into the evening as the upper trough begins to deepen over the Tennessee Valley. The cold front from Monday will still be just south of Tennessee and nearly stationary. Most of the precipitation will shift south and east Thursday. Then Friday through Sunday models are developing an upper low over the upper mid west which deepens the trough and brings moisture over the front into the eastern Tennessee Valley as shortwave energy rotates through upper pattern. The upper flow becomes more southwest by Friday and with low pressure moving east along the front this will enhance the precipitation as shortwaves move through. The upper low will move into the western Great Lakes by Sunday. Rainfall amounts from Wednesday through Sunday could reach 1 inch or more in the northeast to around 3 inches in the mountains of North Carolina so some localized flooding is possible if any training of rainfall develops. High temperatures will be in the lower to mid 80s Tuesday and then upper 70s to lower 80s through Saturday which is several degrees below normal. Lows will be below normal as well, though only by a few degrees. Temperatures will warm a few degrees Sunday. TD && .PRELIMINARY POINT TEMPS/POPS...
