Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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.

.UPDATE...
Issued at 738 PM CDT Tue Jul 21 2026

Quick update for this evening revolves around current thunderstorms
now moving into our northern Middle TN counties. These storms
will continue to move southward over the next several hours and
present a damaging wind gust threat of 60+ mph and heavy rainfall
leading to flash flooding in several areas. While the tornado
threat has diminished, please don't sleep on these storms. Radar
is suggesting wind speeds capable of dropping large trees and
limbs which can cause plenty of damage -- as well as rainfall
rates on the order of 3 to 4 inches an hour. If you go under a
severe thunderstorm warning, please treat it as you would a
tornado warning and take proper shelter.

Storm threat should end by midnight leaving light to moderate rain
across our southern counties into the early morning hours. Flash
flood watch continues until 7 am for many of our mid-state
counties.

&&

.SHORT TERM...
(Rest of today through Wednesday Night)
Issued at 1113 AM CDT Tue Jul 21 2026

A surface front is moving south through Missouri into central
Illinois this morning ahead of a shortwave in the northwest upper
flow. The combination of lift and the ample instability and
moisture at the surface will allow storms to fire across southern
Indiana and Ohio over the next couple of hours. Some activity is
already bubbling across our northeastern counties and some heavy
downpours can't be ruled out this afternoon, but the main severe
concern will be with the activity coming out of Kentucky this
evening as bulk shear increases. Damaging winds will be the main
severe storm threat this evening and into early Wednesday along
with a very low risk of a tornado along the TN/KY state line.
Instability and storm organization will decrease the further
storms move south and the deeper we get into the overnight hours.
The window of greatest severe potential looks like 7 PM to around
1 AM.

In addition to the severe threat, some instances of flash flooding
will be a threat. PWAT values are around 1.9-2" across Middle
Tennessee, so very high rain rates can be expected with storms
today and tonight. HREF and associated CAMs show pockets of 2" of
rain with 90th percentile values showing the potential for over 4"
in isolated areas. With the wet July we've had so far, this would
be sufficient for flash flooding in those areas. The HREF shows
the higher probabilities of over 2" and higher 90th percentile
values along and east of I-65. A Flood Watch is in effect through
12z Wednesday.

By 12z Wednesday, the surface front will be draped across the area
from SW to NE. South of the surface front, additional showers and
storms will be possible Wednesday afternoon along the plateau.
Shear will be lower than tonight, so I don't expect any severe
activity Wednesday afternoon. Behind the front, lower dew points
will filter in from the northwest through the day and into
Wednesday night. The surface front will be through the entire area
by Wednesday night which will usher in a very pleasant night with
low dropping into the low to mid 60s.

&&

.LONG TERM...
(Thursday through next Tuesday)
Issued at 1113 AM CDT Tue Jul 21 2026

To start the long term period, we will be in the nicest airmass
we've had so far this summer. Dew points on Thursday will be in the
low to mid 60s with highs in the low to mid 80s. Friday will be
similar but a couple degrees warmer. A shortwave will ride northwest
upper flow and approach the area Friday night into Saturday which
will reintroduce some low to medium rain chances. Temperatures will
creep up over the weekend with the possibility of a couple more
shortwaves bringing additional storm storms chances going into early
next week. There is some uncertainty of how far east ridging
influences pushes which will affect our rain chances and
temperatures next week.

&&

.AVIATION...
(00Z TAFS)
Issued at 618 PM CDT Tue Jul 21 2026

The first 6 hours of this TAF cycle will be riddled with TS and
gusty winds as a broken line of thunderstorms moves into TN from
the north. These should come to an end for all terminals by 05-06Z
this evening and while cats will improve after the storms for
CKV/BNA/MQY, MVFR cigs will return around sunrise Wednesday at
BNA/MQY. CSV/SRB will bear the brunt of longer MVFR cigs through
the night and sticking around after storms until lunchtime on
Wednesday. Winds outside of storms will be light and we will see a
shift to the northwest/north after storms pass. With storms, winds
may be gusty at times with northwest to north gusts of 30 to 40
kts.
