The episode as NWS IWX wrote it up.
Pre frontal trough and remnant outflow boundaries allowed convection to develop. Moderate to extreme instability was in place with SBCAPE over 3500 J/KG and DCAPE around 1500 J/KG. However, shear profiles were marginal. More concentrated damage occurred in a few spots in northwestern Ohio.
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 Jul 10, 2:20 PM EST, 3 hours 57 minutes earlier.
Area Forecast Discussion National Weather Service Northern Indiana 320 PM EDT Wed Jul 10 2019 .SYNOPSIS... Issued at 319 PM EDT Wed Jul 10 2019 Hot and humid conditions will prevail into this evening with a chance for a shower or storm in some locations. Somewhat cooler and less humid air arrives for Thursday with another small chance for a shower from late morning into the mid afternoon period. && .SHORT TERM...(This Evening through Thursday) Issued at 319 PM EDT Wed Jul 10 2019 Unstable, but capped environment in place across the area with SBCAPE values in the 2500-3500 J/KG range. Cu have popped across the region but remain shallow given the capping and lingering subsidence behind this mornings wave. Challenge remain on coverage/placement/intensity of convection into this evening with the picture really no clearer. Multiple subtle possible triggers (lake breeze far NW, remnant weak convergence in far SE, pre- frontal trough working east through IL. Also possible that nothing is able to develop until upper wave draws closer and just grazes the area this evening. All these factors warrant no more than slgt chc to chc pops until clearer signals appear. Main threat with anything that forms will be heavy rain and maybe locally gusty winds with little shear existing at this point to organize anything. Boundary interactions and arrival of trough this evening may increase shear locally. Hot and muggy conditions will linger into this evening with heat indices in some areas flirting with 100 for an hour or 2 and plenty of mid to upper 90s elsewhere. Pre frontal trough will bring somewhat less humid air to the area, but still leave plenty of moisture around for the day Thursday as another disturbance and more pronounced front arrive late morning into the afternoon. After collaboration, have expanded slgt chc pops further N and W to account for at least some limited potential for a shower (rumble of thunder?). && .LONG TERM...(Thursday Night through Wednesday) Issued at 319 PM EDT Wed Jul 10 2019 High pressure will settle into the region and provide a mainly dry period. Temperatures will slowly warm starting Saturday back well into the 80s with near/above 90 degree temps still likely into next week along with return to at least some humidity. Can't rule out a few chances for a shower or storm next week as weak disturbances ride the edge of the upper level ridge. Will also need to watch how tropical system in the Gulf evolves and possible impacts towards middle of next week. && .AVIATION...(For the 18Z TAFS through 18Z Thursday Afternoon) Issued at 105 PM EDT Wed Jul 10 2019 KIWX radar indicating morning showers have either dissipated or exited east of the area and latest VIS satellite showing clearing skies over both TAF sites along with sct diurnal CU. Best synoptic scale forcing well to the north as water vapor imagery depicting upper trough over southern Ontario/northern great lakes with mid level speed max rounding base and pushing through northern WI this afternoon. Meanwhile convective complex continues pushing southeast through MO/E KS into very unstable airmass where surface based CAPES are over 5000J/Kg. So while our area does continue to destabilize this afternoon...lack of focus for organized convection should keep any development scattered over the area. Arrival of cold front later tonight will have unfavorable timing for instability but does have better moisture/mass convergence. Will therefore continue trend from current TAFs and keep mention confined to VC and monitor development and amend as needed. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE.
