Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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, 9.7 hours before the alert went out and 221 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, May 31, 2:48 PM CDT, 1 hour 56 minutes before
Area Forecast Discussion National Weather Service Duluth MN 248 PM CDT Mon May 31 2021 .DISCUSSION...(This evening through Sunday) Issued at 247 PM CDT Mon May 31 2021 Summary: Possible fog moving inland from Lake Superior for tonight and Tuesday morning. Gradual warm up ahead with more summer- like weather. Mostly dry conditions as we move through the week. A cold front has moved through the region this afternoon sparking a few showers and thunderstorms over northwestern WI. Also, showers and thunderstorms have developed along the higher terrain over the Minnesota Arrowhead which will drift southeastward. Do not expect any severe thunderstorms at this time as the best instability will continue to shift into northeast Wisconsin. Skies will likely clear out as we move into the evening hours as diurnally driven clouds fade. We will likely again see fog in the morning, especially near Lake Superior and northwest Wisconsin with good radiational cooling. Not expecting a dense fog advisory over the land at this time, however, this cannot be ruled out near Lake Superior where rather dense fog over the lake may develop. Temperatures will be on a steady increase through the week as winds continue to be out of the south/southwest. Drier air will funnel in from the west allowing relative humidity values to drop off over the western counties of our CWA through the week. However we probably will not need any fire weather headlines because the winds will be less than 10 knots. Towards the end of the week is when we will start to see some warm air return to the Northland as a strong upper level ridge axis over the west will tilt towards northeast Minnesota/northwest Wisconsin allowing temperatures to be in the upper 80s/low 90s for next weekend away from Lake Superior. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 1250 PM CDT Mon May 31 2021 Mostly VFR conditions for all terminals today with west/northwest winds 5 to 10 knots. Slight chance for showers and thunderstorms for DHYR as a cold front continues to push through the region this afternoon. Patchy fog will likely move back in Tuesday morning for KDLH and KHYR. && .MARINE... Issued at 1250 PM CDT Mon May 31 2021 Mostly clear skies with winds out of the northwest 5 to 10 knots with waves less than 2 feet. Some areas along the south shore could see showers and thunderstorms this afternoon. Severe weather is not expected, however some strong wind gusts and small hail are possible. Fog will likely develop along all western lake superior near shore waters during the overnight hours of Monday into Tuesday morning. A dense fog advisory is possible. && .PRELIMINARY POINT TEMPS/POPS...
