Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS IWX wrote it up.
Elevated storms developed north of a warm front that was draped generally along and south of U.S. 24. While sufficient instability existed, weak shear was in place, keeping the storms more of the pulse variety. A few of the storms produced locally damaging winds.
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 8, 12:22 PM EST, 1 hour 26 minutes earlier.
Area Forecast Discussion National Weather Service Northern Indiana 122 PM EDT Fri Jun 8 2018 .SYNOPSIS... Issued at 118 PM EDT Fri Jun 8 2018 Areas of thunderstorms continue this afternoon. Heavy rainfall at times which may lead to localized flooding. Periodic showers and storms will be possible through the weekend. A few of these storms may be strong at times with gusty winds...small hail...and locally heavy rain possible. Temperatures will remain near seasonal averages with highs around 80 and lows around 60. && .SHORT TERM...(Today and Tonight) Issued at 346 AM EDT Fri Jun 8 2018 Fairly typical June-like weather anticipated for today and into the weekend. Large scale synoptic pattern characterized by high amplitude and large wavelength ridge over central NOAM that slowly drifts east before being undercut by seasonably strong Pacific jet just starting to come onshore. High latitude positioning of this ridge opens the door for several convectively-enhanced shortwaves to cut through the central CONUS and impact our area. Morning water vapor clearly shows next shortwave slated to arrive later today and bring another round of convection. This wave is fairly broad/weak and will only weaken further per latest guidance as it is ingested into longwave northeast CONUS trough. Nevertheless it will likely be just enough impetus for SCT thunderstorms today given modest moisture/instability. Mid 60s dewpoints should be easily attainable (upper 60s possible) and forecast soundings indicate little/no CIN by afternoon to prevent free convection. Expect a sporadic and disorganized convective event. 0-1km MLCAPE values of 1000-1500 J/kg could support a few stronger updrafts but they will be very "pulsey" given limited shear and lack of substantive forcing. There is virtually no flow in the lower half of the troposphere and any strong/severe wind gusts (while still possible) will depend entirely on wet microburst processes. Locally heavy rain will be the primary threat given weak flow/slow storm motion, low MBE velocities, and PW values around 1.5 inches. Though storms are possible in the entire CWA, best chances for heavy rain will be along/south of US-30 where better moisture resides. Localized flooding possible but not expecting anything widespread and our southern CWA has been relatively dry. RAP13 and HRRR have been insistent on convection developing early this morning along weak stationary boundary. There is a very weak convergence signal with around 500-1000 J/kg of MUCAPE per latest SPC mesoanalysis. Have low chance PoPs for now but it should be noted that if this early morning convection is as vigorous as hi-res CAM's indicate...it could delay and/or subdue our afternoon activity. && .LONG TERM...(Saturday through Thursday) Issued at 346 AM EDT Fri Jun 8 2018 As is typical in these patterns...forecast confidence decreases substantially beyond day1 owing to uncertainties in upstream convective trends. Periodic showers/storms anticipated through the weekend but exact timing and chances very much up in the air. Deterministic models are all over the place regarding timing and track of these subtle waves. Unfortunately this necessitates a broadbrushed approach to PoPs through early next week. A marginal severe and heavy rain threat will continue to exist given moderate instability/moisture but generally weak shear. Temps during the period will be around seasonal averages with highs around 80F and lows around 60F. Large scale pattern breaks down very quickly by Tue with rapid transition to more zonal flow. This will lead to a hot day on Tue as thermal ridge folds east but cold front arrives and brings cooler/drier conditions for Wed/Thu. Some severe possible with this cold front but timing and mesoscale details far too nebulous for any meaningful discussion at this point. && .AVIATION...(For the 18Z TAFS through 18Z Saturday Afternoon) Issued at 118 PM EDT Fri Jun 8 2018 Mainly VFR flying conditions today with periodic thunderstorms and showers over both TAF sites throughout the forecast period. Heavier thunderstorms may lead to brief drops to MVFR visibility and ceilings. Frontal boundary stalled across the area will result in slow moving storms with storm motion from west to east. Better instability near KFWA may lead to better storm coverage by late this afternoon/evening. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE.
