The radar

The Northeast Alabama radar (KHTX), 60 km from the middle of the area, began a volume at 00:45 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 severe thunderstorm 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, 0.8 hours before the alert went out and 104 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 severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Huntsville, AL wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 25, 6:30 PM CDT, 1 hour 15 minutes earlier.

.DISCUSSION...
(Issued 300 PM CDT SAT JUN 25 2016)
The subtropical high remains in place over the mid-south this
afternoon, generally centered over the lower Mississippi valley.
The subsidence has helped to make it a very warm day; as of 2 PM, all
but one site is in the 90s, and five areas sites have heat indices of
at least 103 F. However the subsidence has not been enough to
completely quash air mass thunderstorms, due in part to a weak
convergence axis extending over northwest Alabama.

Isolated convection should subside this evening, and low temperatures
tonight should be a degree or two above persistence. As the upper
high retrogrades into the ArkLaTex Sunday, a weak wedge front will
push westward into northeast Alabama. This combination may help spark
a few more showers and storms tomorrow afternoon. It may also be
slightly not quite as hot. Model guidance for both highs and
dewpoints are just a degree or two lower, and this leaves maximum
forecast heat index readings below 105 for all but a few spots.
Therefore, after discussion with neighboring offices, the heat
advisory will be removed for tomorrow, and instead will expire at 9
PM tonight. It will still be very hot, and it is still important to
stay hydrated and take frequent breaks.

The cold front currently over the Plains/Upper Midwest will push
southeast over the next 48 hours, dropping into Tennessee by midday
Monday. Convergence with this front will be sufficient to spark
scattered to numerous showers and thunderstorms. A strong wind gust
or two cannot be ruled out, but with minimal shear, modest Downdraft
CAPE, and high precipitable water expected, storms will be mainly
heavy rain producers.

Rain chances will linger at least into Monday night. There is some
disagreement about when the front will push through; most models have
drying occurring by 12Z Tuesday, while the ECMWF is 6-12 hours
slower. The ECMWF may be right in this instance but for now the
forecast will continue with the model consensus, tapering PoPs off by
12Z Tuesday. Cold and dry advection behind the front will send
temperatures plummeting into the upper 80s for Tuesday highs, and dew
points into the lower 60s by Tuesday evening. Low temperatures
Wednesday morning may actually fall below 70.

Dry weather will continue through roughly Friday, though agreement on
moisture return is not very good yet. Rain chances could resume
Friday afternoon into Saturday as northwest flow and an eastern CONUS
trough remain in place. Temperatures will remain closer to seasonal
averages, with highs around 90 and lows in the mid- upper 60s.

.AVIATION...
For 00Z TAFs: Showers and storms have moved east KHSV and dissipated
over KMSL over the last few hours. However, cannot rule out a
scattered -TSRA redeveloping before 26/02Z or 26/03Z. However,
confidence that they will directly affect either airport is low, so
only kept a VCTS in forecast through 26/02Z. Expect VFR conditions to
continue unless storms form and move over either terminal. Each
terminal has had some rainfall, so think patchy fog towards daybreak
could lower VSBYS to around 4SM or 5 SM. Otherwise, added gusts to 16
KTS tomorrow after 26/15Z.
