The episode as NWS PAH wrote it up.
Isolated thunderstorms formed during the heat and humidity of the late afternoon hours. One of the storms produced minor wind damage. The storms dissipated by sunset as solar heating decreased.

Area Forecast Discussion
National Weather Service Paducah KY
241 PM CDT Sat Jun 16 2018
.SHORT TERM...(Tonight through Monday night)
Issued at 241 PM CDT Sat Jun 16 2018
Most of the region has reached 100 heat indices as of 19Z, with the
exception of west Kentucky where readings are only in the upper 90s.
The current heat headlines look good at this point and do not plan
on any adjustments at this time.
A decent cu field has developed and a few isolated showers have
developed on opposite ends of the CWA. The latest CAM guidance
really does not show much, but the bottom line is that very
isolated thunderstorms cannot be ruled out over much of the
region through the remainder of the afternoon. We will maintain
the slightest of PoPs for it.
Tonight will be dry with light or calm winds. This should allow
temperatures to drop into the lower 70s, if not the upper 60s in
some locations, which should provide some relief from the heat.
Given the good radiational cooling conditions, some patchy light fog
will be possible.
Despite the mid and upper-level ridge holding strong over the area
12Z NAM and GFS soundings indicate a little better chance of deep
convection developing Sunday afternoon over southern portions of
the region and Monday as well. This is not saying much, but will
result in a very slight chance diurnal PoP over mainly southern
portions of the area each day.
Afternoon heat indices will climb into the 100-105 range Sunday
and Monday. The lone exception may be the southern Pennyrile. We
may need to consider expanding the Heat Advisory based on the
4-day 100+ threshold, but we will let the midnight shift consider
this further.
.LONG TERM...(Tuesday through Saturday)
Issued at 241 PM CDT Sat Jun 16 2018
Relatively good agreement among operational and ensemble model
solutions lends to somewhat higher than average confidence in the
overall synoptic pattern during the long term. This confidence is
tempered by less certainty over more specific temporal and spatial
placement of precipitation chances inherent in the type of pattern
forecast.
Starting with Tuesday, the upper level ridge over the southeastern
U.S. will be in the process of breaking down as energy from an upper
low over the Great Basin begins to spread east into the Plains.
Nevertheless, the influence of the ridge should keep much of Tuesday
dry, with only isolated thunderstorm chances primarily during the
heat of the day. It will be another hot one with highs forecast in
the lower 90s on Tuesday and lows Tuesday night from 70 to 75.
From Wednesday through the remainder of the week, the increasing
influence of energy approaching from the Plains paired with a weak
stationary frontal boundary draped just north of the forecast area
should help to focus greater shower and thunderstorm coverage. Even
though better chances should stay aligned with peak diurnal heating,
chances really cannot be ruled out at any time given the proximity
of the nearby frontal boundary and timing of individual vorticity
maxima. Very warm and muggy conditions are expected to persist with
forecast highs in the upper 80s to near 90 and lows in the lower
70s.

The 18Z TAFs are VFR. An isolated thunderstorm cannot be ruled
out this afternoon. Some patchy MVFR fog also cannot be ruled out
throughout the area near sunrise in the morning. Confidence in
these possibilities is too low to mention in the forecast.
