The episode as NWS DLH wrote it up.
A cold front crossing the region during the overnight hours of the 20th into the 21st brought a band of showers and storms to northwest Wisconsin. A low level jet ahead of the front led to the storms becoming more intense as they moved across the area. These storms produced damaging winds that resulted in sporadic reports of downed trees and powerlines.

Area Forecast Discussion
National Weather Service Duluth MN
1232 AM CDT Tue Jun 21 2022
.DISCUSSION...(This evening through Sunday)
Issued at 406 PM CDT Mon Jun 20 2022
Summary: Hot and humid conditions continue tonight. Strong to
severe thunderstorms are expected over central and north-central
Minnesota tonight and may affect the remainder of the Northland
before sunrise Tuesday morning. Temperatures trend cooler
starting Tuesday with periodic shower and storm chances later
this week into the weekend.
A high-amplitude ridge axis stretched from northwest Ontario into
southeast Missouri this afternoon. At the surface, an area of low
pressure was centered over northwest Ontario with a cold front
extending southwest to a secondary low near Aberdeen, SD to a
third low center near Sidney, NE. Thunderstorms have developed
along and either side of the boundary in the past few hours as
far south as northwest Kansas. Meanwhile elevated convection has
begun to percolate over north-central Minnesota in a zone of 800-
700 mb convergence ahead of a northward moving shortwave trough.
The trough axis was roughly from near Fargo to northern Iowa and
was visualized well in the GOES-East Band 8 upper-level water
vapor imagery. The elevated showers should slowly migrate
northward through 21.01Z. I don't expect those showers to pose
much risk of severe weather. The 20Z SPC RAP analysis shows 2000-
3500 J/kg of MLCAPE with almost no MLCIN remaining. However, even
with the mid-level height falls, there appears to be insufficient
convergence and forcing for ascent to support surface-based
convection east of the cold front at this point. Effective bulk
shear is maximized to the west of the front and marginal over
central and north-central Minnesota this afternoon.
Look for showers and thunderstorms to become more numerous near
the cold front and eventually grow upscale into one or more
MCSes. South-southwesterly steering flow oriented parallel to
the front will support this upscale growth and a general storm
motion to the north-northeast. These MCSes will bring a
potential for damaging wind gusts of 60 to 80 mph. The effective
shear will increase later tonight as the front pushes eastward
and a south-southwesterly low-level jet develops. If a few storms
develop ahead of the main lines, they may produce large hail,
perhaps as large as golf balls. SPC upgraded portions of central
and north-central Minnesota to an "Enhanced" Risk of severe
storms, mainly focused on that damaging wind risk tonight and
early Tuesday morning.
The uncomfortable heat indices will continue into this evening
for the Northland, and perhaps overnight in northwest Wisconsin.
Did not make changes to the expiration time of the Heat Advisory
this afternoon and will let the evening shift trim it as
temperatures cool tonight. The cold front will progress slowly
eastward overnight and will likely be over the Arrowhead to
central Minnesota to northwest Iowa by 12Z Tuesday and will move
through northwest Wisconsin during the afternoon. A few storms
may linger through the night and into Tuesday morning, weakening
as they move out of the Northland by late morning. Heat and
humidity will be a concern for portions of northwest Wisconsin
Tuesday with high temperatures in the upper 80s to low 90s and
heat indices in the middle 90s. If showers end earlier and skies
remain clear over those areas, dangerous heat will be possible
ahead of the front on Tuesday. Elsewhere on Tuesday temperatures
will trend cooler with less humidity. Continued cooler on
Wednesday with highs in the 70s and low 80s.
A progressive upper-level pattern is expected for the remainder
of the week into the weekend. There will be additional chances of
showers and thunderstorms for at least portions of the Northland
each day Thursday through next Monday.

.AVIATION...(For the 06Z TAFS through 06Z Tuesday night)
Issued at 1232 AM CDT Tue Jun 21 2022
The first wave of storms continue to work through the Arrowhead and
the Twin Ports this evening. A secondary push of storms is expected
to crawl up from the south in conjunction with a low level jet and a
cold front moving in from the west. Primary threat with these storms
continues to be damaging winds. Excessive rainfall at BRD may lead
to minor flooding. Storms are expected to taper off before sunrise.
Some MVFR ceilings will move in from the north impacting INL and
possibly BRD in the morning. Lastly, gusty winds out of the west
will be prevalent at all terminals tomorrow with speeds in excess of
25 kts.
&&
.MARINE...
Issued at 406 PM CDT Mon Jun 20 2022
Southwesterly winds will continue tonight at around 5 to 15 kt,
strongest along the immediate shorelines particularly near the
Twin Ports. Winds will remain southwest through Tuesday with some
stronger gusts up to around 25 kt possible especially near the
Twin Ports and the Apostle Islands, which may be hazardous for
small craft. Wind speeds will lessen a bit Tuesday night. Areas of
fog may be possible at times, especially tonight, along with
chances for showers and thunderstorms tonight.
