The radar
The Northern Indiana radar (KIWX), 89 km from the middle of the area, began a volume at 16:44 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
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
Cncnati-Daytn, OH (KILN), launched 12:00Z, 4.7 hours before the alert went out and 180 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.

Area forecast discussion, Jul 12, 6:14 AM EDT, 6 hours 28 minutes before
Area Forecast Discussion
National Weather Service Northern Indiana
614 AM EDT Sun Jul 12 2020
.SYNOPSIS...
Issued at 918 PM EDT Sat Jul 11 2020
A few lucky folks may see some passing rain showers tonight,
mainly those toward the interstate 65 corridor. Those headed to
Lake Michigan beaches should note that high waves and dangerous
currents are expected in the afternoon. Heat and humidity increase
through the week.
&&
.SHORT TERM...(Today and Tonight)
Issued at 253 AM EDT Sun Jul 12 2020
Latest radar trends showing convective complex continues to
weaken as it moves south of the forecast area...just clipping our
far SW CWA. Water vapor imagery showing short wave trough axis
rotating out of the mid-MS valley with associated surface frontal
wave near the central IL/IN border. These latest trends casting
doubt on precip chances for our area today...but HREF members
still re-developing convection ahead of secondary frontal boundary
dropping southward out of Michigan...forecast soundings lend
support for this with at least some instability...CAPE around
1000J/kg...and latest KIWX radar loop showing scattered
development just to the NW. So going forecast of slight/low chance
POPs for today still on track and plan to continue. Upper trough
axis exits to the east this evening and surface ridge begins to
build into the area tonight bringing dry forecast along with less
humid air mass that will drop lows down to around 60F.
&&
.LONG TERM...(Monday through Saturday)
Issued at 253 AM EDT Sun Jul 12 2020
Weak surface ridging extending down through the great lakes and
midwest will bring dry weather to the area Mon-Tue. Less humid air
mass will have temperatures comfortably near or just below normal
Monday with highs 80-85 and lows u50s-near 60 before warming back
to at or above normal Tuesday as mid level ridge axis shifts
eastward over the area bringing modest 30-50m height rises. Short
wave energy ejecting from the base of closed upper low over
northern Manitoba will send next system into the great lakes
region mid-week. Latest deterministic model runs ECMWF/GFS/CMC in
pretty good agreement on timing centered around Wednesday night
and majority of GEFS members also favor this timing. Model blend
capturing this trend despite spreading some low chance POPs too
far back into Tue night. Flow then becomes increasingly zonal over
the region and therefore lower confidence in subsequent short
wave timing. Surface frontal boundary takes on more of an E/W
orientation and stalls out in this zonal pattern further
complicating efforts to find targets of opportunity to eliminate
low chances POPs days 5-7.
&&
.AVIATION...(For the 12Z TAFS through 12Z Monday Morning)
Issued at 609 AM EDT Sun Jul 12 2020
A few showers ahead of the cold front did make it into the
vicinity of SBN this morning, and they may even see some rain.
Still kept just VCSH because not confident anything will pass
directly over the terminal. The shortwave responsible for this
activity is diving southeast with the trough axis expected to
follow behind this morning. Thus the better chances for
thunderstorms will be this afternoon near FWA, which will handle
with VCTS for now. Winds will be light variable this morning,
becoming northerly and perhaps slightly gusty in the wake of the
front.
