The episode as NWS DLH wrote it up.
A deepening low pressure system over the Northern Plains moved northeast across the Northland late on the 24th. Fueled by strong southerly flow, the thunderstorm complex began to bow as the cold front advanced to the east. This line of storms produced damaging winds which lead to many trees downed and power outages across northern Minnesota.

Area Forecast Discussion National Weather Service Duluth MN 1010 PM CDT Fri Jun 24 2022 .MESOSCALE UPDATE... Issued at 1008 PM CDT Fri Jun 24 2022 An MCS continues to spread east to southeast over northwest Minnesota as of 10 PM. A few wind gust reports to around 70 mph, as well as funnel cloud sightings, have been reported east of Thief River Falls and northwest of Bemidji. Plenty of surface- based CAPE around 2-3k J/kg persists out ahead of the MCS with temperatures in the mid 70s and dew points in the mid to upper 60s from roughly Koochiching County south to Aitkin county and points west. Further east, onshore flow from Lake Superior has resulted in temperatures and dew points about 10 degrees colder, and surface-based CAPE drops to near zero within about a 20 mile periphery of Lake Superior. Low-level lapse rates are favorable for the MCS to continue mostly unimpeded where higher CAPE and 0-6km shear to around 30-40 knots exists. Areas from Koochiching south to Aitkin counties and areas west will have the best chance at seeing damaging wind gusts to around 70 mph as this line of storms comes through. The highest PWAT values and moisture transport around 1.6" are centered over east-central Minnesota, with relatively drier air further north over the Boundary Waters. The MCS will most likely follow the CAPE gradient to the southeast, bringing both the severe threat and heavy rain threat down towards the Brainerd Lakes region. While storms will likely still persist as the MCS moves east towards Lake Superior, they are more likely to become elevated and thus the threat for strong winds will be lessened a bit. Storms are expected to move into western portions of the region within the next hour, then towards the Twin Ports/North Shore around 1 to 2 AM. Storms are expected to weaken considerably as they move into northwest Wisconsin due to diminishing surface-based CAPE. && .DISCUSSION...(This evening through Thursday) Issued at 347 PM CDT Fri Jun 24 2022 Summary: Severe weather is expected tonight mainly over our western area, with large hail, strong winds, and minor flooding possible. An active pattern continues through the rest of the forecast period, with periodic chances for showers and storms throughout the weekend and next week. Convection throughout the morning has made a dent in today's severe potential, but has not eliminated it completely. The environment will still have upwards of 2500 J/kg of MUCAPE across the area this evening. Wind shear is a little lacking, but 0-6km bulk shear values between 25-35 kts could still present a marginally supportive shear to the storms. The best wind shear is expected to be around the Brainerd Lakes area. Hodographs show a small turning of the winds in lower levels in the areas where the best chances for severe weather exist, but it is questionable whether storms will be able to tap into that as a developing cap is expected to keep the storms elevated. Finally, the tall, skinny CAPE profile throughout model soundings along with PWATs up to 1.25 inches indicate the threat for some minor flash flooding in isolated areas. Currently stationary in ND, a line of storms along a warm front will be swept across the Northern Plains into the Upper Midwest along the system's cold/occluded front as an upper level shortwave moves east to meet it and provide the upper level support for the storms. The line will move through the Northland starting late this evening and through most of Saturday. The main threats from this system will be large hail and damaging winds. Some of our far western counties could see winds over 70 mph. Once this system moves out of the area, slight chances for showers along the international border will persist into Sunday under cyclonic flow aloft. These would be light showers with occasional rumbles of thunder and are not expected to be severe. Subsident conditions will settle over the Northland for most of Monday, with sunny and dry conditions. Since flow aloft will still be out of the northwest, temperatures should remain seasonal in the mid 70s. Overnight, a shortwave trough starts us off on an active pattern with showers and thunderstorms possible Monday night through Tuesday afternoon across the area. This active pattern will continue for the rest of the week with multiple rounds of showers and thunderstorms. && .AVIATION...(For the 00Z TAFS through 00Z Saturday evening) Issued at 610 PM CDT Fri Jun 24 2022 VFR conditions for all terminals initially before showers and thunderstorms work their way in from the west after 02Z and move eastward. Expect the showers and thunderstorms to drop ceiling and visibilities to a mix of IFR and MVFR through the afternoon. Once showers and thunderstorms exit the region, VFR conditions will again dominate the weather for all terminals. && .MARINE... Issued at 347 PM CDT Fri Jun 24 2022 Thunderstorms are expected tonight through the most of Saturday. Some storms could be severe with hazards including strong winds, large hail, and frequent cloud-to-water lightning. On the back end of the system, winds are expected to increase to above 20 kts Saturday night into Sunday. If these persist, a Small Craft Advisory may be needed for that time period. && .PRELIMINARY POINT TEMPS/POPS...
