The episode as NWS IWX wrote it up.
A line of strong to severe storms moved across the area in the afternoon and evening of Wednesday, June 18th, 2025. Damage consisted of tree damage, scattered reports of power lines down, and some associated roof and siding damage to buildings and homes. Wind gusts were estimated to be between 50-60 mph. There were a few reports of quarter to golf ball size hail in northeast Indiana.

NWS Northern Indiana wrote its last area forecast discussion before the first event at Jun 18, 12:49 PM EST, 2 hours 38 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Northern Indiana 149 PM EDT Wed Jun 18 2025 .KEY MESSAGES... - Enhanced risk for severe thunderstorms this afternoon. All hazards possible. - A few lingering showers and non-severe storms tonight into Thursday morning. - Hot and humid conditions developing this weekend into early next week. Afternoon heat indices around 100 degrees, mainly Sunday through Tuesday. && .DISCUSSION... Issued at 149 PM EDT Wed Jun 18 2025 Arcing line segments of convection will track through the area this afternoon (3-9pm EDT) as a well defined MCV and associated sfc reflection lift east-northeast into the lower Great Lakes from west-central IL. Embedded strong to severe supercells and bowing segments remain likely given favorable shear and instability profiles. MLCAPE values likely ranging from 1500-3000 j/kg from north to south by this time, while low-mid level southwest flow also ramps up with favorable deep layer shear pushing 40 knots plus. All hazards are on the table with wind damage remaining the most likely hazard given the strong forcing, though SPC tornado chances have increased given increased 0-3 km shear and SRH with slight backing noted upstream in METARS near the sfc low track. Locally heavy rainfall and large hail also remain a concern. Chances for scattered showers and a few non-severe storms then continue tonight into Thursday morning, especially northern zones as the low center tracks through the Great Lakes through the Great Lakes. Otherwise, synoptic scale gusts into the 35-45 mph will be possible in wake of MCV late this afternoon into this evening into areas mainly south of the Michigan state line. Heat wave remains on target for this weekend into early next week as an upper level ridge expands over the region. Headline worthy (100F plus) PM heat indices possible. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1233 PM EDT Wed Jun 18 2025 We are monitoring storm development in Illinois at this time as these storms move towards our forecast area. A line (or multiple clusters) of strong to severe storms is expected to move west to east across our forecast area between 19Z to 01Z tonight. The primary hazard will be damaging wind gusts with a few tornadoes possible too (especially in northern Indiana south of US 30). Greatest chances for severe wind gusts at KSBN will be between 20-22Z and at KFWA between 21-23Z this evening. Expect MVFR to IFR visibilities and ceilings as the storms move through. Southwesterly winds will be gusty even before storms move through at 20-25kts. Conditions dry out overnight and into the day Thursday. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...None. OH...None.
