Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Green Bay/Straub, WI (KGRB), launched 12:00Z, 12.0 hours before the alert went out and 153 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Jun 10, 2:58 PM CDT, 3 hours 59 minutes before
Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 258 PM CDT Fri Jun 10 2022 .SHORT TERM... (Issued 258 PM CDT Fri Jun 10 2022) Tonight through Saturday night: Messy northwest flow continues across the region, with numerous shortwaves rotating across the area. The bulk of the rain has pushed southeastward as of early afternoon, but some additional development is taking place along a weak boundary across the northern portion of the CWA. Bottom line, expect to see isolated to scattered showers and a few thunderstorms into early evening. Most of the overnight is expected to be dry, before additional showers and storms move in from the northwest tomorrow morning. Showers and storms will likely be more widespread tomorrow compared to today, with better upper level support and a front settling in from the north. Precipitation will persist into Saturday evening before coming to an end Saturday night. Highs tomorrow should be similar to today, with low to mid 70s expected. Boxell && .LONG TERM... (Issued 258 PM CDT Fri Jun 10 2022) Sunday through Friday: High pressure centered north of Lake Huron will nose into the area on Sunday, bringing mostly dry and pleasant conditions. There is a low chance for a few showers, especially south and west of Madison, but suspect that the vast majority of the area will be remain dry on Sunday. A strengthening warm front is expected to start lifting north through the area on Monday, which will likely result in a pretty significant temperature gradient, depending on the exact timing and frontal position. A few thunderstorms are possible with the advancing front as well. Tuesday continues to look like a very hot and humid day, with increasing potential for heat indices to approach 100 degrees across portions of the area, as air temperatures warm into the mid 90s. Thunderstorm chances will return to the area Wednesday as a front starts to move through. The airmass ahead of this front will be very unstable, but weak convergence along the front and mid level dry air might limit thunderstorm coverage. That said, anything that does develop could be on the strong side given the instability in place. An additional front may push through the area on Thursday or Friday, with a return to more typical temperatures. Boxell && .AVIATION... (Issued 258 PM CDT Fri Jun 10 2022) VFR will prevail through tonight with just a few scattered showers and thunderstorms through early evening. Dry weather is expected tonight. Additional showers and thunderstorms are expected to move through the area during the day on Saturday. Ceilings are generally expected to remain VFR, but may fall to MVFR in and around the heavier shower activity. Visibility restrictions are also expected with any showers/thunderstorms. Winds through the next 24 hours will generally remain from the southwest. Boxell && .MARINE... (Issued 258 PM CDT Fri Jun 10 2022) High pressure will continue to move east over the Ohio Valley today, reaching the Mid Atlantic by tomorrow morning. Weak low pressure then moves from the Dakotas into Wisconsin tonight into Saturday night. A weak cold front will shift south across the region Saturday night into Sunday. Winds should remain relatively light through the weekend. East to southeast winds increase a bit on Monday into Monday night, ahead of a warm front lifting north across the area. South winds will then increase through middle parts of next week. Boxell && .MKX WATCHES/WARNINGS/ADVISORIES... WI...None.
