The episode as NWS PAH wrote it up.
A strong cold front moved through SW Indiana around 0200-0300CST on Feb 28th as strengthening low pressure moved towards the Great Lakes. Gusty gradient winds occurred ahead of the front during the evening and behind the front towards early morning. Thunderstorm activity in SW Indiana overnight was most organized with the frontal passage.
The local office's own words before the first event, 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 the first event at Feb 27, 6:02 PM CST, 58 minutes earlier. Its key messages:
Area Forecast Discussion
National Weather Service Paducah KY
602 PM CST Tue Feb 27 2024
.KEY MESSAGES...
- Wind Advisory remains in effect through 3 AM CST for gusts up
to 40 mph possible. Winds will shift to the northwest after a
cold front makes passage late tonight and early Wednesday,
with 30 mph or higher gusts still possible.
- The main severe thunderstorm risk begins this evening and
continues into the night. A few discrete cells with tornado
potential are possible this evening, then overnight it shifts
more to a line of storms along and just ahead of the cold
front, with damaging winds, large hail, and isolated tornado
hazards.
- Temperatures turn sharply colder after the cold front's
passage. Wednesday and Thursday highs will struggle into the
40s, with Wednesday night lows in the 20s and Thursday night
lows in the lower half of the 30s.

.DISCUSSION...
Issued at 115 PM CST Tue Feb 27 2024
CAM modeling shows two camps for convective action...one is warm
sectored, cap busting discrete cells that would carry a higher
tornadic threat and commence early-mid evening. The HRRR and
the FV3 are the most robust with this, shall we call it,
conditional output. All model solutions then go more certain
with linear development as the cold front moves in, with squall
line damaging winds/large hail/isolated tornado threats into the
overnight. A slight to now enhanced risk covers our area and we
agree with that uptick based on the latest data. Compared to
previous instances of February severe weather outbreaks, there
is good consistency in signal, particularly with respect to wind
fields. CGI tied their all time dew point maximum in the month
of February, reaching 65 degrees (previous record February 28,
2017). That was the day of the Perryville, MO EF4.
Gradient tightening continues as the low evolves and drives the
approaching cold front. The Wind Advisory will remain in place
until late tonight. As the front moves in, (gradient) wind gust
maxima will briefly wane. Then after fropa, winds shift to the
northwest and stiffen/get gusty again. It looks like these gusts
will be to 30 mph or better, but maybe stay just shy of
headline extension. This is something to monitor closely though,
in case that becomes warranted on future updates.
The souped up environ includes >1" PW's for 90th percentile
climo, but the speed of movement of the system means the quick
1/2-1" of locally heavy rainfall should preclude anything more
than localized impacts that are commonplace for prone areas.
A significantly colder air mass draws in behind the cold front
for Wednesday and Thursday. Highs will struggle into the 40s
with lows Wednesday night in the 20s, and the lower half 30s for
Thursday night. This precedes another moderating period over the
weekend where we return to 60s (Saturday), then 70s (Sunday)
heading into early next week.
