What was reported inside it

Time	Report	Where	Remark
Jul 8, 6:54 PM CDT	TSTM WND GST 50	6 E Madisonville, KY	ESTIMATED 50 MPH WIND GUST IN ANTON, KY.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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 12:00Z, 11.8 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.

and move to a place of safety inside a sturdy structure such as a 
basement or small interior room.

For your protection move to an interior room on the lowest floor of a
building.

Large hail and damaging winds and continuous cloud to ground
lightning is occurring with this storm. Move indoors immediately.
Lightning is one of nature's leading killers. Remember, if you can
hear thunder, you are close enough to be struck by lightning.

Torrential rainfall is occurring with this storm, and may lead to
flash flooding. Do not drive your vehicle through flooded roadways.

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 Paducah, KY wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 8, 3:30 PM CDT, 3 hours 17 minutes earlier.

Area forecast discussion, Jul 8, 3:30 PM CDT, 3 hours 17 minutes before

Area Forecast Discussion
National Weather Service Paducah KY
330 PM CDT Thu Jul 8 2021

.SHORT TERM...(Tonight through Saturday night)
Issued at 325 PM CDT Thu Jul 8 2021

Ongoing convection along advancing weak frontal system will
continue to need to be monitored for a few isolated
strong/marginally severe cells/clusters/segments late this
afternoon into the early evening. Low level lapse rates of 8-8.5 C
have developed along and ahead of the activity, with marginal
effective shear of 25-30 kts.

The activity should gradually diminish as we lose the low level
instability during the evening hours, as the surface front stalls
out most likely somewhere over western KY. This boundary could
supply enough low level forcing on Friday to generate additional
isolated to scattered storms, esp during the heat of the day.
However, higher chances of convection will come Friday night as
some mid level energy within northwest flow aloft interacts with
the low lvl boundary. Highest rain chances will lie along and
north of the surface boundary as west-southwesterly flow at H85
overruns the front. Not expecting amounts to get too far out of
hand, but would not be surprised to see some locations pick up a
good 1-2 inches of rain by Saturday morning, esp over portions of
sw IN into se IL.

The next major feature that will develop Saturday and Saturday
night will be a fairly deep mid/upper level trof and associated
surface low over MO as the old surface front in our forecast area
finally lifts north out of the region. This will likely put us in
more of a warm sector regime during the day Saturday, with
additional showers and scattered thunderstorms from time to time.

A surface front associated with the system in MO could approach
portions of se MO later in the afternoon, and serve to enhance the
storms in that region. Will need to monitor for the possibility
of at least a few stronger to severe storms as a mid level short
wave energy ejects east beneath the main trof and increases the
forcing along the surface front.

.LONG TERM...(Sunday through Thursday)
Issued at 325 PM CDT Thu Jul 8 2021

Models show the upper level low over the northeast Kansas/northern
Missouri/southern Iowa vicinity Sunday through Monday night, finally
lifting into the Great Lakes region by Tuesday night. This will be
followed by a couple more weak upper level trofs. Southerly flow at
the surface will continue to bring plenty of low level moisture into
the middle Mississippi and lower Ohio valleys Sunday and through the
work week.

Widespread showers and scattered to numerous thunderstorms are
expected across the PAH forecast area through the day Sunday. This
time period will be our highest chances and precipitation amounts in
the extended.  Chances will decrease from west to east Sunday night,
then increase again Monday with daytime heating, with the highest
chances remaining across our eastern counties. This pattern will
continue Monday night and Tuesday.  As the upper low finally lifts
northeast Tuesday night, convective activity will be primarily
diurnally driven, with isolated to scattered showers and
thunderstorms Wednesday and Thursday.

High temperatures will be below normal Sunday and Monday due to
clouds and precipitation, then readings will trend back upward by
mid week.  Highs Wednesday and Thursday will be near to a little
above normal from around 90 degrees to the lower 90s. Overnight lows
will be near to a little below normal Sunday night and Monday night,
the increase to a little above normal Wednesday night.

&&

.AVIATION...
Issued at 1235 PM CDT Thu Jul 8 2021

A cold front will bring scattered TSRA development this
afternoon. Included VCTS at all terminals, but will likely need to
go with groups an d or tempos with time as the convection
develops during the afternoon hours. Convection will end during
the evening as the cold front settles along the AR/TN borders.
SSW winds this morning will become WSW this afternoon behind the
cold front, all at around 5-10 kts.
