Outflow from thunderstorms in the area resulted in a possible gustnado.
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 May 24, 4:57 PM EST, 2 hours 18 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Northern Indiana 557 PM EDT Fri May 24 2024 .KEY MESSAGES... - Shower and thunderstorms return this afternoon, moreso this evening, with severe storms possible, mainly west of Indiana 15/US 131. - Greater chances for showers and thunderstorms Sunday afternoon and night with both severe storms and possibly heavy rain/hydro issues existing. - Lingering showers may impact activities on Memorial Day and Tuesday. && .UPDATE... Issued at 554 PM EDT Fri May 24 2024 The strong to severe threat looks isolated/limited locally into this evening, though will have to monitor a multicell cluster and associated outflow wind segment(s) that could bring isolated wind damage to areas east into our northeast/central IN zones through 8-9 pm. The main cold front, upstream near the IA/IL border, is currently active and will shift slowly east through the area later tonight with additional chances for storms. Not expecting much in the way of a severe threat though given poor timing and worked over air mass (small hail possible given lingering steep mid level lapse rates). && .DISCUSSION... Issued at 210 PM EDT Fri May 24 2024 A low pressure system moving through the Midwest today is expected to bring thunderstorms to the area this afternoon and evening. A line of storms currently moving through northern Illinois could reach the western extent of our forecast area as early as 3 pm. However, isolated storms are beginning to pop up ahead of this line, in the vicinity of a warm front draped from Berrien County southeast through Allen County and into Ohio. This will lift slowly northward this afternoon, and sfc CAPE will increase to over 2000 J/kg with dewpoints rising into the 60s. Yet bulk shear is marginal at only around 25-30 kts, so main threat will be strong outflow winds. High- res models have not done a very good job capturing the ongoing convection, so confidence is low in the exact timing and location of storms, but still think the best chances for rain will be between 8 pm and 4 am when the cold front pushes in. The front will still be over the area Saturday morning with lingering showers, but as it makes its way east, drier air under northwesterly flow will dominate through Saturday night. Another low pressure system will arrive on Sunday afternoon with more showers and thunderstorms. This has a better chance of severe weather with NAM sfc CAPE up to 4000 J/kg and bulk shear 50+ kts. There is also a greater threat for heavy rain on Sunday evening with precipitable water increasing to around 2 inches. Rain may be slow to move east Monday morning, but by Memorial Day evening, most locations should be dry. It will also be much cooler behind this system with highs only in the low 70s and breezy winds. Large scale troughing over the eastern half of the US means that unsettled weather will continue on Tuesday. On Wednesday, high pressure will build over the plains, and drier conditions will return, though it will remain cool. It will stay dry on Thursday, but warm a bit as the ridge shifts east. && .AVIATION /00Z TAFS THROUGH 00Z SUNDAY/... Issued at 554 PM EDT Fri May 24 2024 Outflow boundary and thunder chances have pushed east of KSBN with dry conditions expected to start. Upstream cold front near the IA/IL border does push east through KSBN late this evening into the early overnight thunderstorms possible, though confidence on this activity hanging together remains low. Will continue to monitor multicell cluster now west-southwest of the KFWA that will have the potential to bring a round of convection and possibly some brief gusty winds this evening. Mainly VFR and trending dry otherwise through the day tomorrow. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...None. OH...None. MI...None.
