The episode as NWS IWX wrote it up.
An Mesoscale Convective Vortex moved through the US 30 corridor resulting in flooding rain on its northern edge. The Northern Indiana NWS office recorded 0.72 of rain in just under 15 minutes. Rain totals of 3 to nearly 5 inches was common in La Porte, St. Joseph, Elkhart, De Kalb, and Noble Counties.

Area Forecast Discussion National Weather Service Northern Indiana 117 PM EDT Sat Jul 19 2025 .KEY MESSAGES... - Showers and thunderstorm chances will increase this afternoon and evening (mainly between 1 and 7 pm EDT). Some of the storms may be strong to severe, with the primary threats damaging winds, heavy rain and localized flooding. - Additional shower and thunderstorm chances exist later tonight into Sunday evening, but confidence in areas most likely to be impacted is low as influence of today's storms and final frontal position will be key. - A significant period of dangerous heat and humidity is expected to build in from the middle to the end of next week, with heat indices in excess of 100 degrees anticipated. && .DISCUSSION... Issued at 355 AM EDT Sat Jul 19 2025 Showers and storms have been impacting southern MN into N WI the past several hours. The most organized area has remained focused in southern MN where low 70 dewpoints are feeding into the cluster of storms. Models have struggled to handle the overall evolution of the upstream convection, with HRRR finally seeming to have caught on to the overall scenario. This area of storms is likely to drift ESE along the CAPE/theta-e gradient. Thus far these have been sub-severe, with some potential for upscale growth with time as it moves across NE Iowa through 12Z as noted in the most recent SWOMCD. Have trimmed pops considerably through 15Z. Current alignment of likely pops is oriented more SW to NE and progressive across the CWA, but anticipated location of the instability gradient and trends in HRRR suggest SW third to half of the area (roughly US-30 south and east) may have the best chance for a line of strong to severe storms as it arrives during peak heating. Slight risk was maintained by SPC for the entire area, but could see some changes in later outlooks to focus the greatest threat to the area noted above. Locally heavy rain will remain a concern, but progressive nature should limit overall flooding potential. A weak front will drop south into the area tonight into Sunday with yet another gradient in moisture setting up. Inherited likely pops in the south have been capped at upper chance given an increasing likihood that the further SW track of storms this afternoon will effectively limit chances overnight. Effective boundary will likely remain across portions of central IL and IN Sunday, with the bulk of new storm development likely to reside in these areas. Far southern counties remain clipped by a marginal risk for severe on DY2 with axis of excessive rainfall also south of the area. While skeptical on inherited likely pops through the day, will leave them alone to see what transpires over the next 24 hours wrt to the best axis for storms. Upper level flow begins to flatten, briefly for Monday and Tuesday with seasonable temperatures and most likely dry conditions. Expansive upper level ridge will then begin its push north, introducing a period of increasingly hot and humid conditions for mainly Wed and Thur with highs near or above 90 and heat indices of 100 degrees or higher. Can't rule out a stray storm or 2 in what will be a very unstable, but likely capped environment. Models disagree on how soon the ridge will flatten in the Fri to Sat time frame. && .AVIATION /18Z TAFS THROUGH 18Z SUNDAY/... Issued at 1259 PM EDT Sat Jul 19 2025 Upstream MCS has degenerated into rain with a few embeded storms. Some convection was trying to get going near LAF, but strong evidence storm development will be delayed with overcast skies already over most of northern Indiana. Kept a window of active storms this afternoon including SBN, but confidence is building that there may not be thunder there (SBN). Kept lingering thunderstorms at FWA. RAP and HRRR models keep FWA active with a stream of energy topping the upstream ridge. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...None. OH...None. MI...None.
