The episode as NWS IWX wrote it up.
Slow moving, compact MCV moved off of Lake Michigan during the afternoon hours of the 9th. A residual stationary boundary stretched roughly from Michigan City southeastward to Van Wert in the morning of the 9th. As the MCV moved further off Lake Michigan, the boundary lifted northward as a warm front, which eventually became orientated northwest to southeast across southern Steuben/northern DeKalb counties. Thunderstorms developed with isolated tornadoes occurring in Steuben county.

NWS Northern Indiana wrote its last area forecast discussion before the first event at Jun 9, 1:26 PM EST, 14 minutes earlier.
Area Forecast Discussion National Weather Service Northern Indiana 226 PM EDT Sat Jun 9 2018 .SYNOPSIS... Issued at 128 PM EDT Sat Jun 9 2018 Thunderstorms have fired along an outflow boundary this afternoon across northern Indiana. This convection will push into Ohio. Expect a lull tonight after sunset but additional storms are anticipated for Sunday. There is a low risk for isolated gusty winds but the main threat will be locally heavy rain and isolated flooding in areas that have already seen heavy rain in the past few days. Temperatures will remain near seasonal averages with highs around 80 and lows in the 60s. && .SHORT TERM...(This Evening through Sunday) Issued at 224 PM EDT Sat Jun 9 2018 MCV that moved through Chicago this morning has kicked up storms this afternoon and will continue through this evening as the atmosphere recovers from earlier precip. Better chance for some stronger storms along and east of I-69 where higher instability is present with biggest svr threat of gusty winds likely from precip loading and heavy rain as pwat values are between 1.5-1.75. General storm trend has been progressive which should limit some flooding potential. Overnight looks relatively quiet as the CWA area falls in between two MCS's. Latest trends show another MCS will be developing over MN/IA state line and propagate south and east through IL into IN. Current thinking is that the bulk of the precip will miss our CWA to the south as it rides downs the instability gradient off to our south and west. Best chance to see rain and thunderstorms will be in far south and southwest zones. After the MCS passes through the rest of the day looks dry until near sunset as showers and thunderstorms fire up again across the area along the remnant outflow from the overnight MCS. Severe threat is minimal due low amounts of shear and instability. && .LONG TERM...(Sunday Night through Saturday) Issued at 224 PM EDT Sat Jun 9 2018 Monday it appears the stationary front gets pushed to the south which will keep areas north of US 6 dry while areas south with showers and thunderstorms. Still some uncertainty in how far south the stationary front goes as models have been moving it back and forth. Cold front approaches the area on Tuesday with more showers and storms. Can not rule out a severe threat on Tuesday as instability increases with CAPE values reaching into the 2000 j/kg and near 7 degree mid level lapse rates. However, shear profiles in nearly unidirectional and deep layer shear is under 30 kts which will limit organization and development. Mid week a ridge develops upstream to our west but models disagree on how far eastward the ridge moves. Canadian puts us under the ridge while GFS and ECMWF keeps it just to our west. Placement of ridge axis will determine how wet or dry we become. Kept chance pope at times to due to several waves of energy will ride the ridge and move into our area toward the end of the week bringing additional chances of rain. && .AVIATION...(For the 18Z TAFS through 18Z Sunday Afternoon) Issued at 128 PM EDT Sat Jun 9 2018 Convection has fired along an outflow boundary this aftn that has laid out from ne to sw due to this mornings tstm activity. KFWA is likely to be impacted in the 18-21Z time period before this activity pushes into Ohio for the evening. Conditions are conducive for isolated stronger wind gusts and heavy downpours with stronger storms as precip loading is the likeliest scenario with this pulse type storms. Brief MVFR or IFR conditions will accompany stronger storms this aftn and evening, but otherwise VFR conditions should persist. Passage of the vort max should provide a lull in shower/storm chances late this evening into tonight. There exists a chance for additional upstream convection to impact the terminal sites after 06Z as a more organized convective system moves back into NW Indiana. && .IWX WATCHES/WARNINGS/ADVISORIES...

The Northern Indiana radar (KIWX), 103 km away, was scanning. The volume nearest the first event began at 18:39 UTC.
2 tornado, 1 thunderstorm wind, 1 hail. Local standard time, as filed.
A 10 inch diameter tree as well as numerous tree limbs to six inches in diameter were blown down.
The public reported the hail continued for nearly five minutes.
According to witnesses, a weak, but multi funnel tornado touched down in an empty field, then intensified somewhat as it tracked East Northeast, removing a portion of a roof. It also caused damage to two barn structures as it crossed County Road 150 W. Maximum winds are estimated at around 80 mph.
An EF-1 tornado caused widespread, extensive tree damage, knocking down trees along adjacent railroad tracks. Minor roof damage was noted to a few structures. Maximum wind speeds are estimated around 105 mph.
