The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
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
Minneapolis, MN (KMPX), launched 12:00Z, 1.6 hours before the alert went out and 107 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.

NWS Twin Cities, MN wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 10, 5:58 AM CDT, 2 hours 38 minutes earlier.
Area forecast discussion, Aug 10, 5:58 AM CDT, 2 hours 38 minutes before
Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 558 AM CDT Mon Aug 10 2020 .UPDATE...For 12Z Aviation discussion below && .SHORT TERM...(Today through Tuesday) Issued at 349 AM CDT Mon Aug 10 2020 Large hail, heavy rainfall, and wind-producing storms that formed ahead of an approaching cold front (and provided an impressive lightning show for parts of the area Sunday night) will continue to develop east/southeast early this morning, riding along the instability gradient along the MN/WI border. By mid-morning the severe threat will have diminished, but a few showers could persist along the Iowa border. Drier air works into the area this afternoon bringing clearing skies, and reducing dewpoints into the 40s and 50s. High temperatures today will be a few degrees cooler than climatological normals, with highs in the 75-80 degree range. Lows tonight will be pleasant in the low to mid 50s. Dry weather continues on Tuesday as weak ridging influences the local weather, although temperatures will moderate several degrees with highs in the low to mid 80s. .LONG TERM...(Tuesday night through Sunday) Issued at 349 AM CDT Mon Aug 10 2020 Semi-zonal flow prevails through much of next week, with precipitation opportunities supplied by ripples of shortwave energy in the fast-moving westerly flow. The first of these chances for showers and thunderstorms arrives Wednesday as return flow ensues, and then chances persist through the weekend as western troughing shifts into the north central CONUS. Temperatures will be near to slightly above normal through the period. && .AVIATION...(For the 12Z TAFS through 12Z Tuesday morning) Issued at 558 AM CDT Mon Aug 10 2020 After showers and thunderstorms exit west central Wisconsin (KEAU) this morning, clearing skies and VFR conditions are expected at sites through the remainder of the period. Expect northwest winds with gusts to 20 knots at MN sites this afternoon. Winds will gradually back to the west then southwest this evening. KMSP...No concerns. /OUTLOOK FOR KMSP/ TUE...VFR. Wind SW at 5-10 kt. WED...VFR. Wind SE at 10 kt. THU...VFR with MVFR/TSRA possible. Wind SE at 10G20 kt. && .MPX WATCHES/WARNINGS/ADVISORIES... MN...None.
