Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched 6 storm reports to this flash flood warning; the first came 27 minutes after it went out.

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.

What forecasters said that day

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 Blacksburg, VA wrote its last area forecast discussion before this flash flood warning went out at Jun 19, 3:44 PM EDT, 1 hour 4 minutes earlier.

Area forecast discussion, Jun 19, 3:44 PM EDT, 1 hour 4 minutes before

Area Forecast Discussion
National Weather Service Blacksburg VA
344 PM EDT Fri Jun 19 2020

.SYNOPSIS...
An area of Low pressure will remain over the area into Saturday
before heading off to the east Sunday. A transition to a much
warmer weather pattern is expected early next week, although
scattered afternoon evening thunderstorms will remain in the
forecast.

&&

.NEAR TERM /THROUGH SATURDAY/...
As of 300 EDT Friday...

Saturday marks the summer solstice of 2020 at 543 PM EDT. In
spite of the change in season, temperatures are still being
suppressed by a blocky weather pattern. We are now on day 5 with
respect to entertaining this cutoff Low. This is expected to
change to some degree by Sunday.

Weakening upper Low over the central Appalachians is forecast to
open up into a trough and then move east and off the coast
Saturday. Until then, expect an abundance of cloud cover along
with scattered to numerous showers and thunderstorms. Heating of
the day will promote the strongest activity and the greatest
coverage. Thermodynamic profile through this evening suggest
MUCAPE of 1000-1500 j/kg across the region with PWAT of 1.25 to
1.50. This is expected to support semi-robust shower and
thunderstorm cores with instantaneous rain rates upwards of 3
inches an hour. Mean wind of 15-17kts should keep storm cells
moving, however localized excessive rainfall is still possible
due to the tendency for the deep convection to train around the
periphery of the upper low. Training and backbuilding can and
will lead to isolated flash flooding. Stream basins which exceed
1.5 inches in an hour will likely have problems with flooding
due to the wet antecedent conditions. Rainfall in excess of 2.5
inches in an hour or rain rates of 4 inches an hour may lead to
mudslides in addition to washing debris onto the highways.

Given the low FFG values the antecedent signal is certainly
supportive of flooding if any storm anchoring or organization
can become established. Convective allowing models suggest
randomized coverage from now through 8PM this evening. After
that, loss of daytime heating should lead to weakening.

Can't totally rule out an isolated strong/severe wind gust from
the most robust thunderstorms. Per the moist ground, sub-
severe wind gusts and water loading may produce downed trees,
resulting in power outages.

Models show the precip fading this evening in the west,
and closer to midnight in the piedmont. A few lingering showers
may persist into early Saturday morning, but not confident in
taking pops completely out of the forecast as the upper
low/trough axis will still be over the general region.

Expectation Saturday is for the atmosphere to heat up again with
shower/storm coverage increasing for the afternoon. The upper
trough axis is progged more-so over the eastern CWA so will skew
the better coverage of showers/storms to areas along and east
of the Blue Ridge.

Temperature forecast reflects persistence, but hedged slightly
warmer due to the fact the upper low is weakening with time and
should allow for more breaks in the cloud cover. Again we are
expecting highs in the 70s across the mountains lower 80s
piedmont. Lows should be close to the seasonal norm, maybe a
few degrees cooler in the mountains as we may see some clearing,
supporting lows in the mid to upper 50s. The piedmont to Blue
Ridge will have lows in the upper 50s to mid 60s. Where it
clears out some, and with wet ground, expect fog to form, with
dense fog a possibility.

Forecast confidence is high on temperatures and winds, and average
on pops/sky cover.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
As of 330 PM EDT Friday...

Trough from remnant close low is expected to reach the
Chesapeake Bay and exit offshore Saturday night. With its
departure pattern will become more progressive as we turn our
attention to an approaching upper level trough over the
northern Plains for early next week. This trough will maintain
threat for showers and thunderstorms, but the expectation is for
them to become more diurnally driven. The more noticeable
change will be the increase in temperature. Southwest winds will
introduce warm air advection in addition to increasing
dewpoints...more in line with the summer solstice.

&&

.LONG TERM /TUESDAY THROUGH THURSDAY/...
As of 300 PM EDT Friday...

A deep upper trof and an associated surface low in the Great Lakes
region will trail a cold front over the eastern CONUS in the
midweek. Timing on fropa is uncertain right now, but later guidance
ought to bring some clarity to that issue. Shortwaves will make
their way around the trof through the weekend, helping trigger
convection most afternoons. Per the ECMWF on Friday a strong surface
low and cutoff upper low will stack vertically over the southern
plains and make a beeline for our area, arriving late on Saturday.
Other guidance is split on this feature, with the GFS manifesting
nothing, and the Canadian forming a strong shortwave with a later
arrival date. Given that this feature is in the last 12 hours of the
forecast period, and its formation is questionable, have not given
it much consideration when making PoP decisions.

&&

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
As of Noon EDT Friday...

Mix of MVFR to VFR cloud bases with and VFR visibilities
expected this afternoon and evening. Daytime heating is
resulting in scattered to numerous cloud buildups with
shower/storm coverage the greatest from now through 8PM/00z this
evening.

Showers and storms are expected to weaken and dissipate after
8PM this evening with partial clearing. Will have to watch
clearing as this will increase potential for fog leading to IFR
or lower conditions. Confidence is high that LWB and perhaps
BCB will see IFR to LIFR fog, with BLF seeing IFR to LIFR cigs.
Have high end IFR to MVFR from Roanoke east to DAN/LYH tonight
as well.

Forecast confidence is high on threat of showers today and sub-
VFR at times, but timing in this threat and clearing tonight
with fog is average for confidence.

Extended Aviation Discussion...

The closed upper low will continue to meander about the central
and southern Appalachians Saturday. The low weakens and heads
east by Sunday. As the low weakens, the threat for prevailing
IFR conditions and persistent -RA will begin to decrease.

Showers and thunderstorms, with MVFR ceilings and visibilities
are expected Saturday into Monday, mainly each afternoon and
evening. Scattered MVFR showers and Thunderstorms are expected
Tuesday especially in the west.
