The radar

The Minneapolis radar (KMPX), 75 km from the middle of the area, began a volume at 02:37 UTC, the scan nearest the moment this went out.

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.

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 28, 6:28 PM CDT, 3 hours 10 minutes earlier.

Area forecast discussion, Aug 28, 6:28 PM CDT, 3 hours 10 minutes before

Area Forecast Discussion...UPDATED
National Weather Service Twin Cities/Chanhassen MN
628 PM CDT Sun Aug 28 2022

.DISCUSSION...(This evening through Sunday)
Issued at 253 PM CDT Sun Aug 28 2022

KEY MESSAGES:

- Slight risk of severe storms today with the best chance for severe
  in central Minnesota.

- Dry weather and near normal temperatures for the week ahead.

Today and tonight... Persistent low stratus has limited the heating
somewhat across much of Minnesota today. Dew points are lining up
with forecasts though as they are around 70. This has lessened the
instability some, but we are seeing some signs of these clouds
scattering out from southwest to northeast. We should still warm
enough to achieve ML CAPE in the 2000 J/kg area before the frontal
passage later today. Areas farther southwest could even still see
3000 J/kg or more as they have had greater surface heating today.
This front has initiated some convection to our northwest even with
the cooler temperatures. Although we did think that the cooler
temperatures after morning showers yesterday would suppress
instability, but strong WAA changes that quickly. This could happen
again today, so we will be keeping an eye on trends later this
afternoon into the early evening. The latest HREF suggests convection
to occur ahead of and along the cold front moving from west to east
across Minnesota and Wisconsin. The biggest area of uncertainty right
now is how far south along the cold front will see activity. Based
on the newest CAMs and the HREF it suggests that the best chances for
severe weather will be to the north of the Twin Cities in central
Minnesota. Thunderstorms will continue farther south and the Twin
Cities are on the edge of where severe appears most likely.
Regardless of severe potential, thunderstorms still look likely along
much of the front. This afternoon we are still seeing a cap that has
yet to break and it will likely require the lifting mechanism of the
frontal passage to trigger convective initiation. As with other
frontally forced setups it will likely grow upscale quickly into a
linear threat. We could also see some QLCS tornadoes again like last
night. Behind the cold front we begin our cooler and drier period.

Monday through next Sunday... With a ridge building in and surface
high pressure this next week will be cooler with few chances for
precipitation. Monday still has a chance for some showers, mainly
central Minnesota and north, as the weekend's upper low moves out.
This pattern looks to hold until the very end of the period where a
shortwave could move down into the Upper Midwest from Canada. It is
still early to say much about this. Bottom line expect dry weather
and near normal temperatures through at least next weekend. The next
change in pattern looks like it could arrive then with changes in
precipitation chances and temperatures.

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 628 PM CDT Sun Aug 28 2022

Thunderstorms are beginning to develop near AXN-RWF. These will
become more numerous through 02Z, mainly across central MN, then
spread east as clusters, impacting the remaining TAF sites in the
late evening to early overnight. Otherwise, VFR conditions are
expected through the period although some light fog may develop at
EAU early Monday morning.

KMSP...Timing on TS this evening appears to be in the 03-05Z window.
Severe gusts to 50+ kts are possible if one of the clusters moves
through.

/OUTLOOK FOR KMSP/
Tue...VFR. Wind WNW 5-15 kts.
Wed...VFR. Wind NNW 5 kts.
Thu...VFR. Wind S 5 kts.
