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 Indianapolis, IN wrote its last area forecast discussion before the first event at Jun 13, 9:38 AM EST, 1 hour 17 minutes earlier.
Area Forecast Discussion National Weather Service Indianapolis IN 1038 AM EDT Tue Jun 13 2017 .UPDATE... The AVIATION Section has been updated below. && .SYNOPSIS... Issued at 311 AM EDT Tue Jun 13 2017 A series of upper impulses will move around the edge of an upper ridge. These will not only break down the ridge but also interact with a hot and humid atmosphere to bring chances for showers and thunderstorms through the work week. A cold front will bring more chances for rain for the weekend. Temperatures will remain above normal until early next week, when near average temperatures return. && .NEAR TERM /Today/... Issued at 941 AM EDT Tue Jun 13 2017 Update reflects higher POP axis in vicinity of current showers developing in our area. No capping inversion today and with sufficient instability tied with dry air aloft, gusty winds in stronger storm downdrafts appear in play. Otherwise no real changes. Still expecting 90 given the very warm start. && .SHORT TERM.../Tonight through Thursday night/ Issued at 311 AM EDT Tue Jun 13 2017 Models are close enough that the model blend initialization was accepted for most items. Not a lot of change is expected tonight and Wednesday as additional upper impulses erode the upper ridge and also generate scattered convection at times. Will continue with chance PoPs. A more potent upper wave moves through Wednesday night into Thursday. With better forcing, went high end chance category to low end likely category PoPs Wednesday night into Thursday. As forcing weakens behind this wave, ended PoPs by overnight Thursday night. With the stronger wave moving in, could see some strong to severe storms later Wednesday afternoon into Wednesday evening. The Storm Prediction Center has placed the forecast area into a Marginal Risk in its Day 2 Outlook. Stayed with the model blend for temperatures. Again, high temperatures will likely depend on the amount of convection that develops. It will still be hot and humid regardless. && .LONG TERM /Friday through Monday/... Issued at 253 AM EDT Tue Jun 13 2017 Long term models and ensembles support pops all weekend as a warm, moist and unstable atmosphere interacts with and approaching cold front and upper impulses in zonal flow, around the base of a south central Canada low. The thunderstorms should be ending Sunday night as the cold front is finally expected to move through. After that, the trend will be for not as warm temperatures and dry weather. Blend handles the overall scenario nicely. && .AVIATION /update to KIND TAF/... Issued at 1033 AM EDT Tue Jun 13 2017 VFR with wind near or below 10 knots except within storms where Ohio observations have shown visibility below 2 miles in heavy rain and wind gusts as high as 35 mph. Scattered thunderstorms in this unstable air may be tied with weak convergence in wind field. Current slight scattering of cloud deck as main cluster of storms in eastern Indiana moves away but increasing sunshine will trigger more showers and storms as the day wears on. && .IND WATCHES/WARNINGS/ADVISORIES...
