The episode as NWS IND wrote it up.
Scattered thunderstorms affected the southern half of the state of Indiana during the afternoon and evening of July 3rd. Storm motions were slow as convection pushed east to southeast during this timeframe. These slow storm motions led to rounds of heavy rain over the same area which produced flash flooding in Shelby County. A couple additional strong storms over the southwest portions of central Indiana produced damaging winds.

Area Forecast Discussion National Weather Service Indianapolis IN 330 PM EDT Wed Jul 3 2019 The SYNOPSIS, NEAR TERM, and SHORT TERM sections have been updated below. .SYNOPSIS... Issued at 330 PM EDT Wed Jul 3 2019 Upper waves, a moist and unstable atmosphere and weekend front will combine to trigger off an on thunderstorms through the Holiday weekend. Meanwhile, next week will be mostly dry as a ridge of high pressure builds across the Plains. Temperatures will be near normal through next week. && .NEAR TERM...(Rest of This Afternoon and Tonight) Issued at 330 PM EDT Wed Jul 3 2019 Upper impulses, outflow boundaries, deep moisture and strong instability will result in continued convection with lesser coverage expected late evening and overnight with the loss of solar heating. A few storms could be severe with damaging winds per the Storm Prediction Center Day1 Marginal Risk over all of central Indiana. Slow storm movement and brief heavy downpours could result in localized flooding. The heat will be another issue. With temperatures in the lower 90s and dew point temperatures in the 70s, the Heat Index will approach 100 degrees at times through 6 pm. && .SHORT TERM...(Independence Day through Saturday) Issued at 330 PM EDT Wed Jul 3 2019 Models in good agreement that upper impulse will move over the area through the weekend, and a cold front will drop southeast across the area Friday night and Saturday. The synoptic lift along with small scale boundaries will interact with a warm, humid and unstable airmass and result in the continued threat of thunderstorms. The best chances will be Friday afternoon and Saturday afternoon as the front enters the equation. Slow storm movement and downpours in the stronger storms will result in the threat for localized flooding. Blend afternoon temperatures in the upper 80s look reasonable and with dew point temperatures in the lower and middle 70s, the heat index will be in the 90s during the afternoon hours. && .LONG TERM (Saturday night through Wednesday)... Issued at 305 PM EDT Wed Jul 3 2019 Ensembles continue to show minimal spread in the 500mb height fields for the medium and longer term periods. The quasi-zonal orientation to the heights will begin to relax a little late in the weekend, then it appears some ridging returns across the Central CONUS for towards the middle of next week. Temperatures will generallly return to more seasonal conditions with highs in the lower to middle 80s late in the weekend through early next week, then current indications are that with some ridging returning highs will once again push into the upper 80s to around 90 by middle of next week. Precipitation chances will continue to be the typical diurnally driven development with scattered thunderstorms occasionally throughout the extended periods. There may be a few periods that remain dry in the extended, but at this distance guidance does not provide a clear picture on which period will be dry. && .AVIATION /Discussion for the 031800Z TAFS/... Issued at 203 PM EDT Wed Jul 3 2019 Light flow at the surface has winds generally from the southwest around 10kt or less. Thunderstorms have begun to develop and remain scattered across the area, and may require a change to TAFs for this evening to include mention of TS. Thunderstorms may briefly create wind gusts in excess of 20kts. Cloud bases will be generally around 5KFT with higher clouds around 10-15kft. Later this evening expect winds to decrease to around 4-6kts and could result in patchy fog deeloping once the afternoon/evening thunderstorms dissipate. For the 4th of July, diurnally driven thunderstorms are expected again. Main timing will be around 18Z Thur. && .IND WATCHES/WARNINGS/ADVISORIES...
