A shower developed in northern Marshall County along the outflow from another shower farther southeast. This shower then collided with a trailing boundary of a Mesoscale Convective Vorticity Max that tracked across northeast Illinois into southern Lake Michigan.

The episode as NWS IWX wrote it up.
A shower developed in northern Marshall County along the outflow from another shower farther southeast. This shower then collided with a trailing boundary of a Mesoscale Convective Vorticity Max that tracked across northeast Illinois into southern Lake Michigan. These boundary interactions within a very moist axis lended support for rapid intensification and enhanced low level rotation within this shower. This additional low level rotation allowed the shower to produce 2 brief tornadoes. Lightning was never observed with these showers with cloud tops remaining below 18,000 feet.

NWS Northern Indiana wrote its last area forecast discussion before the first event at Jun 23, 6:00 PM EST, 1 hour 10 minutes earlier.
Area Forecast Discussion National Weather Service Northern Indiana 700 PM EDT Sun Jun 23 2019 .SYNOPSIS... Issued at 700 PM EDT Sun Jun 23 2019 Scattered showers and perhaps a thunderstorm this evening will diminish overnight. A few showers and an isolated thunderstorm are possible mainly Monday afternoon. Lows tonight will drop into the upper 60s, with highs on Monday generally in the upper 70s and low 80s. Mainly dry and seasonable conditions will follow into Tuesday and Wednesday. && .SHORT TERM...(This Evening through Monday Night) Issued at 219 PM EDT Sun Jun 23 2019 Showers and thunderstorms will likely spread sw to ne across the area late this afternoon into this evening. MCV emanating from Mid MS Valley convection will lift northeast into the Lower Lakes in increasing southwest flow. This will finally force a warm front (now just nearing our western zones) northeast through the area with a respectable shot of low-mid level theta-e advection. Highest PoPs/QPF were generally confined to our IN/MI zones given the track of the shortwave and positioning of the moisture axis during this time. Locally heavy rainfall will be possible as precipitable water values near 1.80 inches, though limited residence time of convection in any one spot should limit this to an isolated/minor threat at best. There also remains non-zero chances (Marginal Risk) for an isolated strong/severe storm in our IN counties on the leading edge of this activity 21-01z. A lull in precipitation chances/coverage is then expected behind this upper wave and warm front later tonight into Monday morning as muddled warm sector overspreads. A prefrontal trough, and eventually the main weak sfc cold front, will then sweep east Monday afternoon into early Monday evening with renewed chances for a couple rounds of showers and thunderstorms. Again, SPC has most of the area in a Marginal Risk for isolated strong/severe storms given increasingly favorable/unidirectional deep layer shear and the potential for of a modest ribbon of MLCAPE to develop in advance of either feature. Meager lapse rates and plenty of lingering cloud are definite limiting factors, with greater surface heating and possible positioning of the pre- frontal trough anticipated east of the area by peak heating. With that said, held onto higher PoPs in the afternoon as the main synoptic scale upper trough lifting ne toward the Western/southern Great Lakes takes on a negative tilt. && .LONG TERM...(Tuesday through Sunday) Issued at 219 PM EDT Sun Jun 23 2019 Broad, low amplitude, troughing will linger over the region Tuesday and Wednesday with seasonable temps/humidity. Weak disturbances embedded in this quasi-zonal flow regime make it difficult to completely rule out chances for iso-sct convection late Tuesday into Wednesday. Held PoPs generally in the 10-20% range (mainly diurnally driven) given weak signal(s) and expectations for the bulk of the mid week period to be dry. Increasing humidity and afternoon highs generally in the mid-upper 80s still appear likely late this week as upper ridging over the South-Central US expands northeast into the Midwest/Western Great Lakes. Most of the period(s) should be dry, though once again cannot rule out convection given the potential for small-scale/convectively aided perturbations to ride on the northern fringe of the ridge. The bulk of medium range model guidance has now come to the idea of more substantial troughing into Northeast US next weekend into early next week. The process may send a stronger backdoor cold front through the local area sometime over the weekend, with less humid conditions to follow. && .AVIATION...(For the 00Z TAFS through 00Z Monday Evening) Issued at 700 PM EDT Sun Jun 23 2019 Destructive interference in wake of lead linear squall line pushing through wrn/sw OH along with wwd diminishing/narrow theta-e ridge in ern IL had quashed more vigorous shower/storm development across the terminals. Doubtful this changes later this evening in light of secondary line of upscale intense convection ovr wrn KY. Thus have abandoned most of prior precip mention. Otherwise severely curtailed low level moisture advection calls into question extent of MVFR cig development overnight. Sfc based moisture has ticked up and onset of diurnal cooling this evening will aide in some boundary layer RH increase yet perhaps not enough to warrant implied lower bound MVFR cig heights. Given expectation is toward or after 06z routine issuance will again follow guidance suggestion especially should small area of showers in ern IL expand newd as suggested by RAP/HRRR later this evening. && .IWX WATCHES/WARNINGS/ADVISORIES...

The Northern Indiana radar (KIWX), 58 km away, was scanning. The volume nearest the first event began at 00:11 UTC.
2 tornado, 1 thunderstorm wind. Local standard time, as filed.
The public reported tree limbs were blown down with one tree uprooted.
Video footage indicated a separate wall cloud outside the parent |mesocyclone spawned a brief, thin tornado that touched down near the |intersection of Roosevelt Road and Hawthorne Trail. West facing barn |doors were slightly pushed in as the narrow circulation moved north |across the property with the only other damage noted occurring to |small branches on a nearby tree. The tornado moved north and impacted a outdoor screened structure, destroying it as well as removing siding and shingles from a detached garage. A resident was outside at the time the tornado struck and had to hold onto a beam as the wind hit. A dog was picked up a few feet off the ground and carried to the side of the home and placed down, unharmed. The tornado then lifted shortly after this, also supported by video footage.
The tornado, initially weak and narrow, developed on Cranston Street, just east of Ironwood Drive. The tornado continued to strengthen as it traveled north crossing U.S. Highway 20. By far the greatest damage occurred at the Growing Kids Learning Center on East Ireland Road, just east of South Ironwood Drive. Thereafter the |tornado continued to track north while weakening. The tornado narrowed and dissipated along Ewing Road, just east of Ironwood Dr.
The descent of the tornado into the valley along Ireland Road aided in the rapid intensification of this shallow, low-topped tornadic circulation.
