The episode as NWS IND wrote it up.
During the afternoon hours, a series of thunderstorms moved across north central Indiana. A few of these storms became severe and produced isolated wind damage to portions of Howard and Tipton counties. Most storms remained sub-severe and had limited impacts.
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 Jul 8, 3:09 PM EST, 36 minutes earlier.
Area Forecast Discussion National Weather Service Indianapolis IN 409 PM EDT Wed Jul 8 2020 .UPDATE... The SYNOPSIS...NEAR TERM and SHORT TERM Sections have been updated below. && .SYNOPSIS... Issued at 344 PM EDT Wed Jul 8 2020 The hot and humid pattern with daily chances for periodic showers and thunderstorms will continue the next few days. The shower and thunderstorm chances will increase from Thursday night through Friday though as an upper low tracks southeastward across the Great Lakes Region. Temperatures will dip a bit over the weekend in the wake of the associated cold front, but not by much. High temperatures will still top off in the mid to upper 80s from Friday through Monday. Another warming trend will then commence Tuesday with the 90s returning. After some brief ridging on Saturday, a second wave will bring additional chances for showers and thunderstorms on Sunday. && .NEAR TERM /Tonight/... Issued at 344 PM EDT Wed Jul 8 2020 Diurnally driven showers and thunderstorms have been pulsing all afternoon and will continue to do so through early evening. So far, the main threats have been small hail, gusty winds, and brief downpours. But, of course, cannot entirely rule out an isolated storm reaching severe levels through the evening hours, will continue to monitor. Any storms that have formed so far though have exhibited little movement. Will continue with an SPS through this evening to highlight the heat and humidity. Currently, temperatures are still in the upper 80s/low 90s outside of rain showers/thunderstorms. Areas that have had thunderstorms have had significant drops in temperature though with Indy currently sitting at 74 degrees. && .SHORT TERM /Tomorrow through Saturday/... Issued at 344 PM EDT Wed Jul 8 2020 Much of the same can be expected tomorrow, diurnally driven showers and thunderstorms in the heat of the day. Highs will top off in the low 90s again with dewpoints in the low 70s. Unlike tonight though, shower and thunderstorm chances will increase further tomorrow night as an upper low drops into the Lower Great Lakes Region. Forcing with this low and associated cold front will be from Friday morning through Friday afternoon, and this was captured well by the latest National Blend of Models. As a result, did not deviate from the likely and categorical Pops across the area on Friday. In addition, the slightly lower daytime highs in the mid to upper 80s also look reasonable for Friday. As the aforementioned upper low pushes farther east and brief ridging strengthens over central Indiana, precipitation chances will end across the western half of central Indiana by Friday night with only low chances for showers and thunderstorms into Saturday across the eastern half. The slightly cooler temperatures will continue through the end of the short term period with highs in the mid to upper 80s. && .LONG TERM /Saturday Night through Wednesday/... Issued at 158 PM EDT Wed Jul 8 2020 ECMWF shows NW flow in place aloft on Saturday night through Monday Night due to strong Ridging in place over the western plains. This will allow a cooler and drier flow across Central Indiana for the latter half of the weekend and start of the work week. Chances for rain should be minimal as mainly subsidence will be in play on the lee side of the ridge aloft. Furthermore a significant surface system fails to be present as the surface remains unorganized. There will also be lower chances for diurnal convection as we will be dealing with a less humid air mass. The upper flow is suggested to return to southwesterly by Tuesday and into Wednesday by the ECMWF. Meanwhile at the surface low pressure is suggested to develop over the plains...allowing the return of a very warm and humid air mass to Indiana. You know what that means...BACK TO THE SWEATBOX! Anyways...Expect daily chances for storms to return by midweek with above normal temperatures. && .AVIATION /Discussion for the 082100Z Tafs/... Issued at 500 PM EDT Wed Jul 8 2020 Thunderstorms are firing across parts of central Indiana, but none are currently occurring at a TAF site. Thus will continue with VCTS at all sites and monitor for anything more explicit. Winds will gust some and change direction as outflow boundaries move through. Will try to adjust these as necessary but predictability of new wind direction and exact timing of outflow moving through is pretty low. Previous discussion follows... Mainly VFR Conditions are expected to continue this taf period. The very warm humid air mass in place across Central Indiana will continue to remain in place across Central Indiana this afternoon and through Thursday. Diurnal afternoon convection will continue as convective temps will be reached. Have used VCTS to account for these storms...as confidence for precise locations and timing is low. Any storm that strikes a Taf site may produce brief MVFR to IFR conditions...but the far majority of hours this Taf period will be VFR. After heating is lost this evening...skies will again become mostly clear until heating resumes on Thursday. && .IND WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS...TDUD NEAR TERM...TDUD SHORT TERM...TDUD LONG TERM....Puma AVIATION...JP/CP
