The radar

The Northeast Alabama radar (KHTX), 142 km from the middle of the area, began a volume at 08:06 UTC, the scan nearest the moment this went out.

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 00:00Z, 8.1 hours before the alert went out and 154 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.

.KEY MESSAGES...
Updated at 1220 AM CDT Sun Sep 6 2026

- Major heat risk and triple digit heat indices continue across
  southwest Middle TN with a Heat Advisory remaining in effect
  until 8 PM Sunday.

- Heat risk lessens early next week, but temperatures remain
  above-normal through the forecast period.

- Rain chances are low through this week.

.SHORT TERM...
(Tonight through Monday Night)
Issued at 1021 PM CDT Sat Sep 5 2026

A weak disturbance is passing through the area this evening, and an
unstable environment will continue to support a low chance for
thunderstorms through about midnight. Main concern will continue to
be strong winds due to inverted-V soundings and plenty of DCAPE.
Once thunderstorms diminish, a calm night is then in store with
just the development of patchy fog, particularly across the
Plateau, to watch. Dry conditions expected on Sunday with a little
bit of a dip in the temperatures. Look for highs in the upper-80s
for the Plateau and into the mid-90s elsewhere. Still above
normal, but certainly better than the three consecutive days of
triple digits that BNA has recorded. Thanks to the drier air, heat
indices will also stay below 100 with the exception being across
the southwest where a Heat Advisory remains in effect through
Sunday for those counties.

Temperatures cool a little bit more on Monday with highs in the mid-
80s for the Plateau and into the low-90s west of it. Most of the
area remains dry, but another weak disturbance allows for low to
medium storm chances across the Plateau.

&&

.LONG TERM...
(Tuesday through next Sunday)
Issued at 1021 PM CDT Sat Sep 5 2026

Unfortunately, the main story continues to be the heat. By Tuesday,
the high pressure shifts back over the southeastern US, and
temperatures will warm in response. Highs will be back in the mid-
90s Wednesday. It won't be quite as hot and humid as what we've
been experiencing lately, but it'll still be uncomfortable with
temperatures that are well above normal for September. A pattern
change on Thursday brings a front into the area which increases
rain chances into the weekend. While this front drops temperatures
some, it won't be as strong as you may hope for as above normal
temperatures continue to be favored.

&&

.AVIATION...
(06Z TAFS)
Issued at 1220 AM CDT Sun Sep 6 2026

VFR conditions at majority of TAF sites for the TAF period. Patchy
fog is possible across the Plateau tonight, resulting in MVFR
conditions. Any fog will diminish around 13Z, with northerly
winds prevailing.
