The radar

The Nashville radar (KOHX), 145 km from the middle of the area, began a volume at 22:33 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

Nashville Metro, TN (KBNA), launched 12:00Z, 10.6 hours before the alert went out and 146 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.

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 Nashville, TN wrote its last area forecast discussion before this flash flood warning went out at Jul 17, 12:49 PM CDT, 4 hours 45 minutes earlier. Its key messages:

Updated at 1235 PM CDT Fri Jul 17 2026
Daily rounds of scattered storms will continue through the weekend. Strong winds gusts and heavy rain causing localized flooding are possible. There is a marginal risk of severe storms for the Plateau through the weekend.
Heat indices will reach the low 100s for many areas west of the Cumberland Plateau into early next week. Tuesday will be the hottest day of the period with heat indices nearing or exceeding 105 degrees for much of the area.
Slightly cooler and less humid air is expected late next week.

.SHORT TERM...
(Rest of today through Saturday)
Issued at 1144 AM CDT Fri Jul 17 2026

Diurnally driven cumulus are already popping up across Middle
Tennessee on satellite this morning, with showers and thunderstorms
forecasted for today, yet again. Temperatures will barely get into
the 90s for highs today, with some areas on the Cumberland Plateau
sticking in the mid 80s. Triple digit heat indices are the name of
the game the next few days, so make sure you are staying hydrated if
you have any outdoor plans for the weekend.

Overnight we can expect some patchy fog to develop in Middle
Tennessee. Nothing too dense, but enough to drop visibility a bit.
Overnight lows will dip into the upper 60s to low 70s, and rebound
back into the low 90s with heat indices in the triple digits once
again.

There is a chance for isolated severe storms into the weekend, with
SPC highlighting portions of our area in a marginal risk (level 1
out of 5). Primary hazard with any stronger storms would be gusty
winds and heavy rainfall leading to localized flash flooding, given
the sheer amount of moisture in the atmosphere (with PWATs in
forecast soundings above 2"). The chance for severe weather is low
however, as we lack meaningful shear to sustain decent updrafts and
stronger storms, but an isolated strong storm cannot be ruled out.

&&

.LONG TERM...
(Saturday Night through next Friday)
Issued at 1144 AM CDT Fri Jul 17 2026

Into the work week, temperatures will only continue to increase as
WAA increases at 850mb. This will lead to triple digit heat indices
into early next week, some getting into Heat advisory territory. We
will have to evaluate the need for a heat product as we continue to
approach that point in time. Remember to stay hydrated and take
frequent breaks in the AC or shade if you work outside or have any
activities planned. Until the cold front comes through on Wednesday
bringing cooler and less humid air into Middle Tennessee, diurnal
thunderstorms will continue to be a daily threat. Most of these will
not be strong, but we could see some gusty winds and localized flash
flooding from stronger or training storms.

After the cold front on Wednesday morning, we will enter a quieter
period for the mid-week. Highs will be in the mid 80s for Thursday
and Friday, slowly warming back into the 90s into next weekend.

&&

.AVIATION...
(18Z TAFS)
Issued at 1235 PM CDT Fri Jul 17 2026

Expect mainly a persistence forecast across the airspace today.
High moisture content and instability has encouraged another
afternoon of scattered showers and thunderstorms, warranting
PROB30s for each site. Timing of this sporadic convection may last
a little after 01Z, but CAMs are in fairly good agreement on the
bulk of storms settling down by then. The Cumberland Plateau is
showing a pretty strong signal for fog and low ceilings (IFR to
LIFR), especially for CSV overnight. Current guidance suggests
improvement shortly after 12Z, but with the high humidity and
light winds, CSV and SRB may end up socked in through tomorrow
afternoon. More pop-up storms are on tap tomorrow afternoon as
well.
