The episode as NWS IWX wrote it up.
Weak shortwaves moved across the area within westerly flow during the afternoon and evening hours. Inverted trough and diffuse stationary boundary stretched from Northwest to Southeast across the area. SBCAPE around 2000 J/KG, poorly sheared, in the 0-3 KM and 0-6 KM shear yet locally enhanced low level helicity (100m*2/s*2) existed near the boundary.

NWS Northern Indiana wrote its last area forecast discussion before the first event at Aug 14, 2:22 PM EST, 1 hour 3 minutes earlier.
Area Forecast Discussion National Weather Service Northern Indiana 322 PM EDT Wed Aug 14 2019 .SYNOPSIS... Issued at 320 PM EDT Wed Aug 14 2019 Showers and storms will be possible this evening with damaging winds and heavy rain being the main threats. Then, showers and thunderstorms will be possible mainly during the afternoon and evenings over the next several days. Temperature-wise, highs will be around 80 up until the weekend with highs into the 80s during the weekend and into next week. The humidity will also return for this weekend. && .SHORT TERM...(This Evening through Thursday) Issued at 320 PM EDT Wed Aug 14 2019 An area of cyclonic flow develops across the region and an area of low level convergence across the forecast area coupled with low decent level lapse rates and CAPE values over 1500 J/kg along with 0-6 km bulk shear over 30 kts will provide an environment capable of producing strong to marginally severe thunderstorms this afternoon ahead of sunset. With DCAPE between 800 and 1000 J/kg and inverted-V profiles, wind damage would be the primary threat along with locally heavy rain. With surface vorticity and some low level MLCAPE, a brief funnel cannot be ruled out despite limited low-level turning in the hodograph as evidenced by lacking SRH. Behind the chance for showers and thunderstorms, we'll have to watch for some low stratus to develop. Models are indicating the potential for fog to form with favorable cross-over temperatures and light winds overnight, but cross-sections are not as moist as one would expect for fog development so will hold off on fog mention for now. The most likely place for stratus development appears to be in areas south of US-30 by Thursday morning where models are picking up better low level dew point depression values. Then we'll have to watch the afternoon on Thursday for another chance at showers and thunderstorms as the region of cyclonic flow shifts to our east. This would make the southward translation of an instability trough possible allowing portions of our northeast to see a storm or two. && .LONG TERM...(Thursday Night through Wednesday) Issued at 320 PM EDT Wed Aug 14 2019 The long range period will continue to be characterized by blocking in the Pacific as atmospheric wave breaking allows for the wave train in the Pacific to essentially stall out and for a ridge to build in the East Pacific. Closer to home, Friday appears to start the day dry until a theta-e surge associated with a northwestward traversing shortwave can bring in some cloudiness before sunset. There still is some variance about the location for showers and storms overnight Friday, if at all, so will cap PoPs at chance for now. The blocking in the Pacific likely isn't helping model predictability this weekend with the thunderstorm chances, but a shortwave is able to traverse to the northwest from the Central Plains towards the Great Lakes and has the looks of being a convective complex with it being on the edge of the low level jet, accompanied by large scale convergence and traversing along the gradient of instability. As a result, will continue the chance for showers and storms later Saturday in an area closer to the forcing. The aforementioned blocking allows the trough in the Western US to build somewhat off the East Pacific ridge from late week in the weekend. This allows a trough associated with a low in southwestern Canada to attempt a negative tilt. With the ECMWF and GFS ensemble more limited precipitation-wise than the GFS-op, am more apt to side with the drier solution for Sunday. Still, can't rule out an afternoon shower or storm within an environment with CAPE over 1500 J/kg, shear near 30 kts closer to the lake, temps in the upper 80s to 90 and dew points in the low 70s. For the early work week next week, expect afternoon chances for showers and thunderstorms with highs in the 80s as the trough in the west lifts north and the subtropical high builds into the south. && .AVIATION...(For the 18Z TAFS through 18Z Thursday Afternoon) Issued at 110 PM EDT Wed Aug 14 2019 VIS satellite imagery depicting SCT/BKN diurnal cu over the area this afternoon with cigs primarily VFR with a few MVFR noted on 17Z obs. Diffuse frontal boundary with weak frontal wave continues to meander over the area and will provide focus for potential convection later this afternoon as KIWX radar indicating a few cells already developing just south of KAOH. Uncertainty remains in extent of aerial coverage so plan for now is to stay with VCSH and continue to monitor/amend as needed. Other concern will be overnight and early Thursday morning as forecast soundings indicating saturated boundary layer beneath weak low level inversion which will bring potential for IFR cigs/vsbys near daybreak...especially for KFWA where more residual boundary layer moisture already in place. && .IWX WATCHES/WARNINGS/ADVISORIES...
