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, 8.4 hours before the alert went out and 130 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.

.SHORT TERM...
(Rest of today through Sunday)
Issued at 1015 AM CDT Sat Jul 11 2026

The active, moist pattern persists across Middle TN today with a
continued Flood Watch in effect until 6 PM Sunday. A slow-moving
boundary and embedded disturbances will support to numerous
showers and thunderstorms, particularly this afternoon and
evening. There is a low to medium severe weather threat with these
storms. Damaging wind gusts remain the primary concern, with a
few stronger storms possibly producing small hail and frequent
lightning. Instability will build with daytime heating in this
humid airmass (PWATs of 2+ inches), and shear profiles support
organized clusters or bowing segments. While not a widespread
major severe event, localized strong winds and heavy downpours
will heighten flash flooding risks, especially in areas that have
already seen significant rainfall recently. The isolated to
scattered nature of storms early this afternoon will give way to
better storm coverage through the late afternoon and evening.

Highs today look to top out in the upper 80s to low 90s, with heat
indices near or above 100 (mainly along and W of I-65). Overnight
and into Sunday, lingering storms are likely, maintaining the
flood threat with additional localized heavy rain.

&&

.LONG TERM...
(Sunday Night through next Saturday)
Issued at 1015 AM CDT Sat Jul 11 2026

The upper level pattern begins to shift early next week as a broad
ridge builds westward, helping to cut off or weaken the influence
of the low over the TN Valley. A surface boundary will drift
slowly south, keeping scattered showers and thunderstorms chances
alive, especially Monday into Tuesday. Heavy rain and localized
flooding could still occur where storms train or repeat, but
overall coverage should gradually decrease compared to the
weekend.

By mid to late week, drier conditions take hold under the
expanding ridge, with only isolated diurnal thunderstorms
possible. Overall, precipitation chances drop notably, providing
relief from the ongoing flood risk. Temperatures stay seasonally
warm and humid, with highs in the upper 80s to low 90s and
overnight lows in the upper 60s to low 70s. With plenty of
moisture throughout the region, humidty will keep things feeling
sticky.

.AVIATION...
(18Z TAFS)
Issued at 103 PM CDT Sat Jul 11 2026

18Z tafs are starting VFR and will be much of the afternoon, but
numerous showers and storms are expected to move into and develop
across the area late this afternoon and evening. Some strong TSRA
will occur with very heavy rainfall and gusty winds over 30KT.
Main timing for this activity will be 23Z-06Z. After the storms, a
mix of MVFR/VFR will occur with VCSH. Winds will be WSW with gusts
to 16KT today, with light W to NW winds overnight into Sunday.
