Local storm reports filed while the alert was in force, from inside its polygon or its counties.
Did it verify
Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this severe thunderstorm warning; the first came 59 minutes after it went out.
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 00:00Z, 9.8 hours before the alert went out and 164 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.

What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Twin Cities, MN wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 9, 4:07 AM CDT, 39 minutes earlier. Its key messages:
- Scattered showers and thunderstorms to persist through sunrise, a few producing hail and gusty winds, followed by partial clearing this afternoon.
- The next best chance for rain comes early Tuesday morning, then dry for much of the upcoming week.
- Temperatures to remain very close to normal values through Wednesday, then drop below normal Thursday onward.

Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 407 AM CDT Sun Aug 9 2026 .KEY MESSAGES... - Scattered showers and thunderstorms to persist through sunrise, a few producing hail and gusty winds, followed by partial clearing this afternoon. - The next best chance for rain comes early Tuesday morning, then dry for much of the upcoming week. - Temperatures to remain very close to normal values through Wednesday, then drop below normal Thursday onward. && .DISCUSSION... Issued at 407 AM CDT Sun Aug 9 2026 A bit of a nondescript surface pressure pattern sits over the WFO MPX coverage area with some scattered showers/thunderstorms early this morning over far eastern MN through western WI. A few meager troughs at the surface can be analyzed while the main surface low lingers over eastern SD/NE. Aloft, the large trough emanating from Hudson Bay continues to rotate several shortwave disturbances around its western and southern fringes through the Upper Midwest. The most important feature is LLJ in between 900-700mb, helping spark the thunderstorm activity within an environment sporting a roughly 1.50" PWAT. The moisture/instability gradient shows up nicely at the surface with dewpoints into the low- mid 60s in western MN while dewpoints in the mid 50s to around 60 are evident in eastern MN to western WI. The expectation is that going towards sunrise, the push of the surface low into IA within the elevated moisture/unstable environment will help fill in the area over southwestern- southern MN with additional showers/thunderstorms. Not necessarily expecting much in the way of strong-severe thunderstorms but the storms ongoing overnight have generally produced 0.25"-0.50" hail along with frequent lightning and rainfall rates nearing 1 in/hr. The storms are progressive to the east, thus mitigating flooding concerns thus far. However, should storm coverage overachieve, even FFG over 2 in/hr could be realized in pockets. Storms are expected to wane in coverage/intensity from late morning into the early afternoon, with partial clearing thereafter as the low pressure center and its associated fronts move to the E and SE of the coverage area. This will then allow high pressure to nudge southward from Canada. While this scenario will not bring in an airmass change in terms of temperatures/dewpoints, it will push the lingering frontal boundary far south enough to allow for dry weather to prevail from this afternoon through Monday evening. The front does look to retreat back north just enough to spawn another round of scattered showers/thunderstorms early morning Tuesday, in conjunction with one last gasp from the upper low over eastern NOAM. Like this morning, there is the possibility of a few stronger storms but organization is again lacking as is diurnal assistance due to the overnight timing. The rest of the week looks to run mainly dry aside from an isolated chance here or there of a few showers. The topic then changes to one of temperatures as temperatures will remain generally close to normal through Wednesday with highs in the upper 70s to lower 80s, possibly as high as 84-85 degrees. The upper ridge over the western CONUS is expected to flatten/shift southward slightly while the NOAM trough shifts to the eastern seaboard, making for more pronounced northwest flow aloft for the north-central CONUS. Cooler western Canadian high pressure will slide southeast to the Upper Midwest, bringing a cooler airmass to our region from Thursday onward. This will push highs into the 70s area-wide for the latter portion of the week, with lows into the 50s away from the Twin Cities metro (and near 60 within the TC metro). && .AVIATION /06Z TAFS THROUGH 12Z MONDAY/... Issued at 1205 AM CDT Sun Aug 9 2026 Tricky convective forecast over the next 24 hours due to high uncertainty among the CAMs with not only initiation but also projected development during the TAF period. Very isolated TSRA currently ongoing but mostly away from terminals so have been able to start all sites as dry. That said, a variance of PROB30 timing exists across all sites as pockets of TSRA are generally expected but difficult to go with TEMPO certainty as to where/when. Will monitor radar trends and issue AMDs as needed. Otherwise, mid-level clouds will increase underneath upper level passing cirrus/smoke. Ceilings are likely near and after daybreak, and potentially into MVFR level should TSRA occur near any terminals (which also would cause visibility reductions). Winds may be quite erratic owing to nearby frontal boundaries and convective outflows, but overall to remain under 10kts outside of TSRA. KMSP...Best timing for TSRA still looks to be during the early morning hours up through sunrise, but this could be adjusted should additional clusters develop over the eastern Dakotas which shift east across MN and/or over central MN and drift near the TC metro. Will continue to run with the 10z-13z timing but this could be adjusted earlier or later so radar trends will be monitored closely. Otherwise, mid-level ceilings will develop close to sunrise and persist for much of the day before the mid-levels scour out in favor of high cirrus/smoke passing across the area. Winds overall to remain under 10kts but with potentially erratic changes in direction throughout this TAF period. /OUTLOOK FOR KMSP/ TUE...Mainly VFR. Chc early A.M. -SHRA. Wind NE 5-10 kts.
