The episode as NWS IWX wrote it up.

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Northern Indiana wrote its last area forecast discussion before the first event at Jun 19, 1:17 PM EST, 1 hour 16 minutes earlier.
Area Forecast Discussion National Weather Service Northern Indiana 217 PM EDT Tue Jun 19 2018 .SYNOPSIS... Issued at 125 PM EDT Tue Jun 19 2018 Shower and thunderstorm activity will increase this afternoon and evening, with highs climbing to around the mid 80s south of US 30. Elsewhere, expect temperatures to linger in the mid-upper 70s. Cooler temperatures will round out the work week. && .SHORT TERM...(Tonight and Tomorrow) Issued at 217 PM EDT Tue Jun 19 2018 Vigorous storms developing quickly this aftn within a zone of substantial sfc based instability and weak forcing invof stationary frontal zone. Lack of flow/shear will keep potential storm severity in check however similar to last evening water loading within high moisture content airmass poses a local microburst threat especially along ern flank of small scale cold pools in more cluster convection. Bulk of near term activity expected to follow south of US30 with additional development later this aftn invof trailing outflow boundary extending swwd from short convective segment over srn MI. More uncertain scenario overnight with varying CAMS based solutions/evolutions. Near term convective overturning and stabilization after sunset suggests a waning in additional shower/storm development especially from late evening through Wed morning which lies counter to some deterministic solutions like the RAP which are much more bullish stemming from ewd progression of large scale disturbance out of IA. At the least will give a nod toward near term guidance/trends and knock likely pops down overnight. Passage of upstream disturbance will push frontal zone south into cntrl IN Wed. Some risk for additional showers south of US24 in Indiana mainly late morning into early aftn tied to diurnal heating/destabilization but focus appears much better through cntrl IN. Nonetheless drier and cooler across the remainder of the area within post frontal airmass. && .LONG TERM...(Thursday through Monday) Issued at 217 PM EDT Tue Jun 19 2018 Development of vigorous upper low over the mid MO valley and ewd evolution primary challenge this period. Surprisingly med range spectral solutions fairly similar aloft and suggest dry wx holds Wed night and Thu before active frontal zone bucks back north into the srn lakes Thu night with following showers/storms through Friday night. Ridging sfc and aloft then build through next weekend with moderating temps and dry wx. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday Afternoon) Issued at 125 PM EDT Tue Jun 19 2018 A warm front is draped northwest to southeast just south of the MI/IN border with remnant MVFR CIGs continuing to slowly erode from the southwest toward VFR conditions. Sfc heating will allow for thunderstorms to move in with ample DCAPE and PWs close to 2in. As such, a heavy rain and a thunderstorm wind threat is possible this afternoon with the most likely area south of US-30, including FWA, but SBN could get into a few thunderstorms before evening timeframe. VISBY could also be reduced in storms with heavy rain. Cooler air begins to sag south overnight allowing some lowering of CIGs into MVFR conditions. Some lowering of VISBY is also possible by Wed AM into VFSkipperR. Winds will remain below 10 kts for the period. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE.
