The radar
The Knoxville radar (KMRX), 109 km from the middle of the area, began a volume at 23:27 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
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 12:00Z, 11.4 hours before the alert went out and 230 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.

.DISCUSSION...
Issued at 219 PM EDT Fri Aug 14 2026
The atmosphere remains quite moist and unstable, with scattered
convection again occurring around the area. Given the lack of
shear, the primary threat from the storms continues to be gusty
winds with some marginal severe potential from wet microbursts
mainly over our northern and eastern areas as highlighted in the
SPC marginal risk. The other main concern continues to be flooding
given the abundant moisture, slow movement of the thunderstorms,
and very wet soils over much of the northeastern half of our area.
Any prolonged or repeated heavy rains may result in localized
flash flooding this afternoon into this evening.
The upper jet retreats further north and heights rise over our area
Saturday as the upper ridge to our west expands over our region. Our
southwestern counties may stay mainly dry Saturday as the cap is
likely to strengthen enough to hold closer to the core of the
ridge, although this is still not certain. Further north and east
there continues to be a chance for showers and storms with threats
of wind and flooding similar to today. Sunday currently looks to
have less coverage of showers/storms, with the best chance in the
mountains and our northeast counties.
The other concern heading into the weekend will be the heat. High
temperatures in the mid 90s will be common across portions of the
central and southern valley, and some spots will climb into the
upper 90s. Heat index values will likely approach or exceed 105 in
some locations especially across the southern valley. A heat
advisory issued earlier today will remain in effect through Sunday
for the southern valley and southern Plateau. The heat advisory may
end up needing to be extended further north into the central valley
by later shifts. Monday also looks quite hot but with more
uncertainty, as short wave energy moving by to our north suppresses
the ridge and pushes a weak summertime cold front toward our area
increasing the chances for showers and storms. Given uncertainty on
timing of precipitation and cloud cover that may impact temperatures
that far out, will keep Monday out of the heat advisory for now.
Further out, models generally show some drying for the mid week
period, with the NBM showing a mostly dry day Wednesday before
chances for showers and storms increases again Thursday and Friday.
It will continue to be hot for the Tuesday through Friday time
frame, but currently the heat looks likely to be less oppressive
than during the weekend.

.AVIATION...
(18Z TAFS)
Issued at 1236 PM EDT Fri Aug 14 2026
Showers and thunderstorms will be scattered this afternoon and
not possible to time well at any given site, but will carry
prob30 thunder groups all sites this afternoon. Fog development
chances will at least partially depend on if and when
precipitation occurs at a terminal which is still unknown, so
will keep the MVFR vsby in fog for a few hours at TRI for now.
Otherwise, will have VFR conditions outside of any thunderstorms.
