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 3, 2:37 PM EST, 2 hours 55 minutes earlier.
Area Forecast Discussion National Weather Service Northern Indiana 337 PM EDT Wed Jul 3 2019 .SYNOPSIS... Issued at 114 PM EDT Wed Jul 3 2019 A few showers and thunderstorms will dot the area through the evening hours. Otherwise mostly cloudy skies with a few peeks of sunshine are expected. The remainder of the week continues to offer some thunderstorm chances with high temperatures in the upper 80s. Cooler air arrives on Saturday. && .SHORT TERM...(This Evening through Thursday) Issued at 322 PM EDT Wed Jul 3 2019 Instability showers and thunderstorms continue to be main challenge in the short term. Cloud cover under dirty ridge in wake of last nights convection has kept temps down and instability lower than expected today. In turn, shra/tsra have been more widely scattered and focused more in the northeast where a bit more sun was realized along with some low level convergence. Expect more of this activity to continue into mid evening before diminishing. Cannot rule out isolated tsra overnight given so many subtle short waves and low level moisture in place. Same story again on Independence day with amount of afternoon convection dependent on amount of heating and instability. Expecting more sun than today so think coverage will be a little greater in afternoon and evening. Shear remains quite low with only 10 to 15 knots of 0-6km deep layer at best this period. PWATs continue to be near 2 inches so pulse storms with locally heavy rain and isolated wet microbursts remain primary hazards. Storms this afternoon have shown a very slow motion with weak wind fields so any stronger updrafts that can persist will likely produce torrential rainfall and localized flooding. && .LONG TERM...(Thursday Night through Wednesday) Issued at 322 PM EDT Wed Jul 3 2019 Same pattern and hazards continue into Saturday until main short wave drifts past and takes cold front south with it. High pressure will build over the western lakes and we should finally see cooler temperatures and lower dew points/RH for second half of weekend. Drier weather expected Sunday through Tuesday before next low chance of pcpn toward day 7 with approach of short wave in northwest flow aloft. && .AVIATION...(For the 18Z TAFS through 18Z Thursday Afternoon) Issued at 114 PM EDT Wed Jul 3 2019 A stationary boundary draped over the area, trapped underneath an upper-level ridge can be the focus for isolated showers and thunderstorms through this evening. This boundary looks to be near to perhaps south of SBN. As such, highlighted FWA with a TEMPO TSRA. Should the storm be strong enough, MVFR conditions would be possible. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE.
