What happened
The episode as NWS IWX wrote it up.
A cold front slowly dropped south into our area. Aloft, multiple shortwaves rippled along and ahead of the front which resulted in several rounds of showers and thunderstorms. While no severe storms occurred in Northern Indiana during this period, a rather persistent supercell moved out of Carroll county, moving into far southern Cass county near Young America. While a brief tornado occurred in Carroll county, it lifted before reaching Cass county, yet a very well defined, rotating wall cloud with occasional funnel clouds was followed by spotters into Cass county before weakening.
What forecasters said that day
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 Northern Indiana wrote its last area forecast discussion before the first event at Jun 25, 6:48 PM EST, 1 hour 37 minutes earlier.

Area Forecast Discussion
National Weather Service Northern Indiana
748 PM EDT Fri Jun 25 2021
.SYNOPSIS...
Issued at 249 PM EDT Fri Jun 25 2021
Moderate to heavy rain and isolated strong to severe thunderstorms
will continue at times through the weekend and into next week. A
Flash Flood Watch remains in effect west of I-69 where heavy rain
has already fallen and more heavy rain is expected tonight. There is
a moderate swim risk for Lake Michigan beaches along the Berrien
County, Michigan shoreline today and Saturday. Breaking waves and
currents are expected.
&&
.UPDATE...(This evening)
Issued at 710 PM EDT Fri Jun 25 2021
Evening vis imagery along with sfc ob trends indicate robust
destabilization ongoing where late day sunshine has materialized. In
addition outflow boundary from morning storms was located from ern
IL into wrn IN with aggravated cumulus clouds noted. Moisture rich
boundary layer exhibits low LCL heights and in combination with
increasing mixed layer CAPE suggests robust storms likely to fire
over sw zones towards sunset. Shear, especially in the 0-2km layer
suggests a brief tornado threat for a time invof nwd mixing outflow
besides a damaging wind risk with deeper/moisture laden updrafts.
Evolution of this convection through this evening is likely to train
and presents a heavy rain/flood risk near a MCY to ASW line in the
least.
&&
.SHORT TERM...(This Evening through Saturday)
Issued at 249 PM EDT Fri Jun 25 2021
Showers continue this afternoon with a surface low moving into
southern lower Michigan with a psuedo-warm front extending south
through northern Indiana, and a quasi-cold front draping back
westward across northern Illinois. Between these two fronts there
has been some clearing with diminished convective activity. To the
south, behind the warm front, the theta-e ridge is starting to
nose up into the area, increasing instability. This zone should
become coincident with the low-level jet as it increases over
northeast Indiana and northwest Ohio this afternoon and evening.
Should there be enough clearing in this area to provide sufficient
destabilization, isolated supercells or sustained multicells
capable of producing a tornado or damaging downbursts. Even though
MLCAPE is currently marginal at only around 500 J/kg, it is
projected to increase, effective shear is very favorable at 40 to
45 kts, and effective helicity is above 200 m2/s2. SPC has
therefore added this region into a slight risk for severe storms.
Later this evening another shortwave will move up from the
southwest, bringing more heavy rain, especially west of I-69. High
pressure will push up from the southeast on Saturday, and the axis
of heavy rain should lift somewhat to the northwest, but will
still impact northwest Indiana and southwest Michigan.
Have extended the Flash Flood Warning a bit farther northeast to
account for forecast guidance. Have also extended the watch in
time through Sunday morning. As far as river flooding concerns go,
as of now, several rivers are forecast to reach at least action
stage on Saturday, but major flooding is not anticipated.
&&
.LONG TERM...(Saturday Night through Friday)
Issued at 249 PM EDT Fri Jun 25 2021
A moist baroclinic zone will remain stalled over the area through
much of the long term period with upper troughing to the northwest
and high pressure to the east. Convection may die down some on
Saturday night, with most activity expected to the northwest with
the high pressure ridge still pushing up from the southeast.
Convection should increase again though on Sunday afternoon with
diurnal heating. A similar pattern will follow for Sunday night
and Monday. Gulf moisture will then continue to advect into the
region through the end of the week with persistent southwesterly
flow both at the surface and aloft. This will keep precipitable
water values generally at or above 1.5 inches, which is around 150
percent above normal. Therefore, expect diurnally enhanced
showers and thunderstorms each day.
&&
.AVIATION...(For the 00Z TAFS through 00Z Saturday Evening)
Issued at 748 PM EDT Fri Jun 25 2021
Primarily MVFR this period. Next round of storms imminent as LLJ and
late day destabilization yield an expanding cluster of
showers/storms out of ern IL. Otherwise gusty sw flow expected to
develop by late Sat morning in response to upstream frontal wave
deepening through IA.
