The episode as NWS IWX wrote it up.
The passage of a weak shortwave earlier in the day left a subtle boundary across northern Indiana. This resulted in a few multicell clusters producing sporadic damaging winds. An occupied mobile home was destroyed in San Pierre (Starke County) with the male inside killed and his wife injured.
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 Jun 19, 7:03 PM CST, 1 hour 12 minutes earlier.
Area Forecast Discussion National Weather Service Northern Indiana 903 PM EDT Sat Jun 19 2021 .SYNOPSIS... Issued at 1235 PM EDT Sat Jun 19 2021 There is a chance for widely scattered showers and thunderstorms this afternoon into this evening. Better chances for thunderstorms, potentially severe, arrive late Sunday afternoon into Sunday night. Trending slightly cooler and mainly dry then early next week. && .SHORT TERM...(This Afternoon through Sunday Night) Issued at 300 PM EDT Sat Jun 19 2021 A surface trough will trail a potent shortwave tracking ese toward the eastern Great Lakes this afternoon into tonight. Erosion of lingering MLCIN should favor widely scattered convection in the vicinity of this trough (and/or outflow boundary) by late afternoon-early evening, with latest ob/satellite trends and CAMs favoring our northeast zones (far ne IN/nw OH/sc MI). A few cells could trend strong to severe (hail/wind main threats) given seasonably strong wnw flow in the mid levels, and 1-2k j/kg of MLCAPE. Mainly dry and warm elsewhere in a drier, initially well mixed, environment south of this boundary. The main front then settles south into our southern zones, or just south of the area, later tonight into Sunday morning with quiet wx and lighter winds anticipated CWA wide. Attention by late Sunday afternoon into Sunday night will turn to increasing chances for two rounds of convection. Synoptically speaking, there be an upper level trough amplifying into the north- central CONUS, with ramping downstream southwesterly flow forcing the aforementioned frontal boundary back north toward the Michigan state line by this time. The associated northward flux of moisture and instability, in tandem with increasing deeper layer shear, could set the stage for a severe convective complex (or two). Forcing during the late aftn-eve periods will rely on a small scale lead vort max (or MCV), with the main cold front to follow overnight with additional convective chances if full overturning doesn't occur with the lead wave. Damaging winds and hail appear to be the primary threats, though a few tornadoes remain possible, especially near the warm front late aftn-eve. SPC did increase Day 2 severe wind probs, favoring our nw IN and sw MI areas in a high shear/moderate CAPE environment. && .LONG TERM...(Monday through Saturday) Issued at 300 PM EDT Sat Jun 19 2021 Drier and cooler air will advect in post-frontal Monday into Tuesday, though low chances remain for showers Monday as the upper trough axis translates through. High pressure then dominates into Wednesday and Thursday with temps on the rise. The late week period will then feature the next decent chance for convection. && .AVIATION...(For the 00Z TAFS through 00Z Sunday Evening) Issued at 724 PM EDT Sat Jun 19 2021 Weak low level moisture transport being fed into weak low level front has been sufficient for isolated/scattered shower/storm development over past few hours across southern Lower Michigan. This boundary should continue to slowly sag south this evening as Great Lakes upper wave continues to depart to the east. Some question as to coverage of these showers and thunderstorms into this evening with northern Indiana on the southern periphery of the stronger forcing with the departing wave. Instability gradient is rather strong however, with greater instability along and south of US Route 6. Threat of isolated thunder does exist at KSBN through around 03Z, with some potential possibly working into KFWA for a time mid/late evening. With lesser confidence in coverage at KFWA will continue to omit with the 00Z TAFS, but will need to watch trends as outflow interactions from far northern Indiana storms could be enough to give KFWA brief shower/storm after 03Z this evening. Some patchy fog is possible late tonight along and just in wake of southward sagging frontal boundary and will include late MVFR mention at KSBN. Otherwise, warm front retreats to the north on Sunday with pre-frontal forcing yielding better chance of thunderstorms across northwest/portions of north central Indiana after 21Z Sunday. && .IWX WATCHES/WARNINGS/ADVISORIES...
