The radar

The Northern Indiana radar (KIWX), 29 km from the middle of the area, began a volume at 02:06 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 tornado 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

Detroit, MI (KDTX), launched 00:00Z, 2.1 hours before the alert went out and 262 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, Aug 20, 6:27 PM EDT, 3 hours 36 minutes before

Area Forecast Discussion
National Weather Service Northern Indiana
627 PM EDT Sat Aug 20 2022

.SYNOPSIS...
Issued at 250 PM EDT Sat Aug 20 2022

Upper low crossing the southern Great Lakes will continue to spark
showers and storms at times through Sunday. High pressure follows on
Monday with dry and seasonable weather through midweek.

&&

.SHORT TERM...(Tonight through Sunday night)
Issued at 250 PM EDT Sat Aug 20 2022

Potent upper low over nrn IL this aftn will wobble east into the ern
lakes by Monday. Narrow plume of sfc based instability far se/e from
morning insolation will support the greatest concentration of
showers/storms this aftn. Otherwise prior rain and extensive cloud
cover suggest little more than a shower elsewhere.

Low level warm advection ewd of upper low should promote another
round of shower/storms this evening west/north and overnight
elsewhere as secondary theta-e ridge advects in concert with decent
deep layer forcing.

Upper low pivots overhead Sunday with additional showers/storms
mainly se half in the aftn especially where morning sun can boost
sfc destabilization. A few showers likely to linger far east Sunday
evening yet drying elsewhere.

&&

.LONG TERM...(Monday through Friday)
Issued at 250 PM EDT Sat Aug 20 2022

Backside of upper low may provide one more bout of additional
rainfall far east Monday aftn. Otherwise high pressure ridges in out
of the nrn plains and will yield a dry and seasonable period through
midweek.

&&

.AVIATION...(For the 00Z TAFS through 00Z Sunday Evening)
Issued at 622 PM EDT Sat Aug 20 2022

Brief lull in convective activity to start off the 00z TAF cycle.
Do expect to see convection over west-central IL to move across
northern Indiana over the course of the overnight hours. KSBN
would be the first to experience this next round of convection
around the 2-3z hour with KFWA lagging until closer to 5z. Expect
heavy downpours as well as gusty and variable winds while
convection is over the terminals. Another lull looks possible near
the 12z hour before scattered convection redevelops mid/late
morning hours and persists into the afternoon.
