The episode as NWS PAH wrote it up.
Two more rounds of severe thunderstorms affected the Owensboro area after the morning round. During the late afternoon hours, an organized squall line moved southward across northwest Kentucky. Isolated wind damage was reported, with gusts up to 60 mph at a few locations. During the early evening, an isolated severe thunderstorm tracked southeast across northwest Kentucky. This storm produced hail up to the size of quarters. The storms occurred ahead of a southeastward moving cold front that extended from northern Illinois through central Missouri. A low amplitude 500 mb shortwave overspread parts of central Illinois and Indiana during the evening, accompanied by 60 to 70 knots of mid-level wind flow. The strong wind shear supported organized storm structures, including lines and elevated supercells. Even though earlier rounds of storms stabilized the atmosphere, a strengthening low-level jet favored regeneration of convection along and atop the outflow-cooled air.

Area Forecast Discussion
National Weather Service Paducah KY
300 PM CDT Thu Jun 29 2023
.SHORT TERM...(Tonight through Saturday night)
Issued at 300 PM CDT Thu Jun 29 2023
Heat and thunderstorm complexes are the forecast concerns of the
day.
A 500 mb high continues to build northward from the lower
Mississippi Valley today. Moderately strong northwest mid-level
flow around the periphery of the high has proven sufficient for
organized thunderstorm complexes to track from central Missouri
and central Illinois to the Wabash Valley and Pennyrile of west
Kentucky. The first system this morning laid out an outflow
boundary that has moved west across southern IL and western KY.
This boundary is becoming increasingly active at mid afternoon.
Another convective complex has moved into the kmvn area to west
central Indiana as of 19z. This complex will move across southwest
Indiana by 00z, and a Severe Thunderstorm Watch covers this area.
Southeast Missouri has been rather quiet, which is where the
strongest warming aloft has produced more convective inhibition.
The cam models generally quiet things down tonight as the air mass
stabilizes. Skies should generally clear out overnight. South
winds will keep it quite warm, with lows in the 70s.
On Friday, there is the potential for another convective system to
round the periphery of the high. Again, the main corridor should
be from the lower Wabash Valley and southwest Indiana down across
the Pennyrile area of west Kentucky. The cam models favor the
afternoon hours for this to occur. Trailing outflow boundaries
could generate convection as far west as the Mississippi River,
however convective inhibition due to warm 850/700 mb temps should
again be a limiting factor west of the Kentucky Lake area and in
southwest IL. THe strongly buoyant air mass, combined with soupy
dew points in the mid 70s to around 80, will favor more
torrential downpours in the storms, along with some hail cores and
a few downbursts. The activity should again wind down Friday
night.
As far as heat concerns, the convection has mitigated heat
concerns in southwest Indiana and adjoining areas. The Heat
Advisory for that area is now for Friday afternoon only. Further
west, the Excessive Heat Warning has panned out fairly well.
Despite temps not reaching forecast values, heat indices have
locally topped 110 where dew points have climbed to near 80. The
warning will continue through Friday.
On Saturday, convective coverage should be higher as the influence
of a 500 mb shortwave trough over the Plains increases. The timing
of the storms will determine the peak heat index. Once the models
come into better agreement on the convective timing, the peak heat
index values will become more certain. For now, the heat headlines
will only extend through Friday. THe main concern for Saturday
may become the storms, which could be strong or locally severe.
.LONG TERM...(Sunday through Thursday)
Issued at 300 PM CDT Thu Jun 29 2023
Saturday night and Sunday, the convective coverage will peak as
the 500 mb shortwave trough advances across our region. The more
widespread clouds and numerous showers and storms will limit highs
to around 90 Sunday.
In the wake of the shortwave trough passage, a little subsidence
and drying will result in less convective coverage Monday and
Tuesday. The air mass will remain quite hot and humid. Some
isolated diurnal showers and thunderstorms are expected, but a
washout is not anticipated either day. Highs will be in the lower
90s for the most part, with heat indices below 100.
Wednesday and Thursday could become more stormy. There are hints
that a 500 mb shortwave trough will move east across the Plains
into the Mississippi Valley. This trough would act on a
potentially moist and unstable air mass to produce higher coverage
of thunderstorms.

.AVIATION...
Issued at 1235 PM CDT Thu Jun 29 2023
Thunderstorms over southwest Indiana and northwest Kentucky are
gradually ending from the northwest early this afternoon. A
period of dry weather is expected this afternoon, while another
thunderstorm complex moves east-southeast across central Illinois.
This complex could affect the kevv/kowb sites later this
afternoon, but the potential is too low to include in the tafs.
Areas of mvfr cigs have developed across southern Illinois,
southwest Indiana and northwest KY in association with the
rainfall from storms this morning. These lower clouds will
dissipate with loss of heating around sunset.
Most of tonight is expected to be mainly clear. There will be a
small potential for thunderstorms in the warmth and humidity, but
too low to mention in the tafs.
