The episode as NWS IWX wrote it up.

What forecasters said that day
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 Apr 17, 6:25 PM CST, 3 hours 52 minutes earlier. Its key messages:
- A line of strong to severe storms is expected to move in later this evening and spread east overnight. The greatest severe threat will exist west of Interstate 69 with damaging winds and possibly a tornado or 2 the main concern.
- Some hydro concerns will exist tonight as locally heavy rain accompanies the line of storms. Overall QPF amounts and expected duration should limit additional impacts, but some areas could see localized flooding issues. Thereafter, no additional significant rain chances are expected into next week.
- Much cooler temperatures arrive and persist into early next week with chances for near or below freezing temps Sunday and Monday morning.
- Rain chances may return towards the end of next week.

Area Forecast Discussion National Weather Service Northern Indiana 825 PM EDT Fri Apr 17 2026 .KEY MESSAGES... - A line of strong to severe storms is expected to move in later this evening and spread east overnight. The greatest severe threat will exist west of Interstate 69 with damaging winds and possibly a tornado or 2 the main concern. - Some hydro concerns will exist tonight as locally heavy rain accompanies the line of storms. Overall QPF amounts and expected duration should limit additional impacts, but some areas could see localized flooding issues. Thereafter, no additional significant rain chances are expected into next week. - Much cooler temperatures arrive and persist into early next week with chances for near or below freezing temps Sunday and Monday morning. - Rain chances may return towards the end of next week. && .DISCUSSION... Issued at 226 PM EDT Fri Apr 17 2026 Primary forecast focus is on the well advertised strong to severe storm threat this evening into the overnight hours in association with a strong cold front and plentiful upper level support. Dry conditions are expected through the remainder of the afternoon and most likely to near or just after 00Z. Numerous thunderstorms are expected to develop upstream (some already underway from Minnesota to NE Missouri) in a strongly favorable environment for all modes of severe. As these storms races ENE, they should congeal into 1 or more lines and most likely establish strong cold pools as they move across IL and eventually into portions of Indiana. It remains to be seen just how strong they are as they arrive later this evening, but concerns have increased some that they make it roughly half way through the area before weakening somewhat. This is depicted by some expansion east of the Slight and Marginal Risk areas in the DY1 outlook. By this point, hail should not be a concern, with areas of wind damage (60 to 70 mph) as well as some brief tornadoes will be the main concern. The main severe threat should wrap up in the 6-8Z time frame with lingering stratiform rain behind the main line. Pops have been adjusted for a somewhat faster trend given the impacts of the cold pool pushing the line along sooner than previous indications. With regards to hydro issues, a Flood Watch was contemplated given the potential for 0.5" to 1" of rain (locally higher possible), but with the line being so progressive feel the concerns will be rather limited and can just be handled by Flood Advisories or Warnings as needed. The front will stall out some Saturday as another wave moves along it. The severe threat should remain to our east but some showers and maybe a storm are still possible in SE areas, especially early. After that, we enter a less active period into at least the middle of next week with the only concern being the monitoring of colder temperatures and frost/freeze potential Sunday and Monday morning. Will sort that out after we get this system out of here. && .AVIATION /00Z TAFS THROUGH 00Z SUNDAY/... Issued at 804 PM EDT Fri Apr 17 2026 VFR conditions should prevail through mid-to-late evening with BKN to OVC ceilings around 10k feet AGL at both KSBN and KFWA. A line of showers and thunderstorms will track eastward across the area overnight, mainly between 04z and 11z Saturday. Occasional MVFR conditions will likely accompany the heaviest precipitation cores, along with gusty and erratic surface winds. Showers will likely linger in the wake of this convection w/ MVFR ceilings at or below 2500 feet AGL. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...None. OH...None. MI...None. MARINE...Small Craft Advisory until 2 AM EDT Sunday for LMZ043-046. && DISCUSSION...Fisher AVIATION...Hammer
