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
Roanoke, VA (KRNK), launched 00:00Z, 1.2 hours before the alert went out and 111 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.

Area Forecast Discussion
National Weather Service Blacksburg VA
120 PM EDT Fri Jun 5 2020
.SYNOPSIS...
A cold front will move southeast through the Mid Atlantic
region Saturday. Drier high pressure will follow for Sunday
through Tuesday. On Wednesday or Thursday another cold front
will pass across the eastern United States with a yet another
chance of showers and thunderstorms.
&&
.NEAR TERM /THROUGH SATURDAY/...
As of 100 PM EDT Friday...
Moist airmass in place with precip water of 1.5 to 1.7 inches.
Showers and a few storms have formed across the mountains, but CAPES
and low level lapse rates where they have formed plus a deep warm
layer cloud depth has made for more heavy showers as opposed to
deeper convection.
However, the airmass will destabilize through the afternoon with
best instability progged where sunshine was the greatest this
morning, namely along/east of the Blue Ridge. A few storms could
become severe with damaging wet microbursts, but the bigger issue
may be flooding potential as steering flow remains weak. Flash flood
watch configuration looks good and no changes planned.
Models are in decent agreement in showing higher concentration of
showers/storms along/west of the Blue Ridge in advance of shortwave
over eastern KY. Shortwave moves east to the I-81 corridor by early
evening, then east of the piedmont after midnight. As such will lean
toward likely to categorical pops this afternoon where the flash
flood watch is, tapering to scattered pops of 40-50 in the piedmont.
Support for convection lessens this evening across WV/far SW Va and
appears most will see dry weather by after midnight with lingering
pops possible well east of Danville and Lynchburg.
No change in airmass and clearing skies/wet ground could bring about
areas of dense fog, but some upstream cloud cover with another wave
and the front may hinder this. Will re-evaluate this later this
evening.
Saturday is looking drier despite the front moving in, per strong
subsidence aloft and limited moisture. Models are mainly showing low
chance pops across the mountains. With northwest flow and slightly
drier air by afternoon, temps should warm well into the 80s, with
lower 90s east.
Forecast confidence is moderate for storm coverage this
afternoon/evening and high for lower coverage Saturday.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
As of 12:15 PM EDT Friday...
An upper level ridge will be situated to our west for the start of
the forecast period as we remain just down-flow from an upper level
jet on the backside of a trough. Through Monday, the ridge shifts
westward, bringing the associated surface high pressure with it.
This pattern will lead to a dry period of weather. The warmer
weather of the period will be for the start, then slightly cooler
weather as weak cold air advection arrives with the moving high.
&&
.LONG TERM /TUESDAY THROUGH FRIDAY/...
As of 11:30 AM EDT Friday...
Outside the front/remains of Cristobal, the forecast period remains
calm. After Cristobal makes landfall Sunday into Monday, guidance
continues to show it being picked up by a frontal system that will be
lead by an upper level trough mid to late Tuesday. Before the
front/system arrives, high pressure remains overhead with mostly dry
weather. 00z ECMWF and 6z GFS remain undecided on arrival time for
the front with GFS being the more progressive, showing arrival later
Wednesday. Meanwhile, ECMWF is slower bringing the front in
Thursday, with the only POPs Wednesday being along the southern part
of the Appalachians where moisture will be increasing and
interacting with differential heating. Because of the differences in
models, most blended guidance is having a heard time generating
high, properly timed POPs for the front currently. For now, I'm
going with the ECMWF guidance given the GFS speed bias.
Temperatures before the front will be warm with an increasingly
humid airmass arriving. After, cooler weather arrives with a
notably drier/less humid airmass.
&&
.AVIATION /17Z FRIDAY THROUGH TUESDAY/...
As of 115 PM EDT Friday...
MVFR to VFR ceiling this afternoon with coverage of
showers/storms greatest along/west of the Blue Ridge. Leaning
toward radar trends and 12z NAM allows for tempo groups for all
but the piedmont where a VCTS will be kept. Best threat of
storms will be 18z-23z. Some of these storms will produce very
heavy rain and MVFR to IFR ceilings and visibility.
Storms will dissipate by midnight. MVFR to possible IFR or lower fog
may occur late tonight at all sites, especially BCB/LWB/BLF
Any fog/low cigs Saturday should scour out by 14-15z, with VFR
til 18z.
Average confidence on wind, ceiling, visibility and timing of
thunderstorms.
Extended Aviation Discussion...
A front moves across but appears moisture lacking with
only isolated showers/storms in the afternoon. A shift in wind
direction. to the northwest expected. Dry high pressure will
then build across the region with a period of mainly VFR for
Sunday through Tuesday.
