The episode as NWS MPX wrote it up.
This episode is part 1 of 2 from two rounds of severe weather that occurred during the early morning of June 10th.
A line of strong thunderstorms which had caused widespread wind damage across Minnesota continued into western Wisconsin. The strongest wind gusts had decreased as the line of storms progressed across central and eastern MN. However, emergency managers and law enforcement reported downed trees within their municipalities.
Wind damage for this episode was focused across Pierce, Dunn, and Eau Claire Counties. Estimated wind gusts between 50-55kts produced damage to a couple of farm outbuildings just northeast of Rock Elm (Pierce Co). While farther east, several trees and powerlines were downed between Menomonie and Downsville.
The local office's own words before the first event, 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 the first event at Jun 10, 7:42 AM CST, 3 hours 43 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 842 AM CDT Wed Jun 10 2026 .KEY MESSAGES... - Additional rounds of severe thunderstorms today. All severe modes are possible including damaging wind, large hail, and tornadoes. Greatest severe threat favors far eastern Minnesota into western Wisconsin Wed afternoon into Wed evening. - Slightly cooler than normal temperatures forecast for Thursday through the weekend. && .UPDATE... Issued at 842 AM CDT Wed Jun 10 2026 After the early morning storms the current environment still looks quite unstable across southern Minnesota. Depending on how much we clear out this morning that will impact how much the instability spreads across eastern Minnesota and western Wisconsin. This area is the main area of concern due to the forcing with the cold front expected to be well into central Minnesota by this afternoon when storms are expected to form. There should be just enough of a cap out there that we will need either or a combination of surface heating and/or stronger forcing from the front to cause CI. Current CAM and high resolution ensembles suggest 18Z/1pm as when this CI occurs and the cap is broken. With ample deep layer shear available in the area along and ahead of the cold front all modes of severe weather will be possible. These initial storms will be in an environment capable of supercells and then as more cells initiate upscale growth is expected with the wind threat becoming the main risk. With upscale growth the hail threat would diminish and the tornado risk will be more QLCS quick spin up in nature. These storms are expected to move at a fairly quick pace like the storms we saw early in the morning. This would leave some elevated instability for this evening. This could trigger a second round of storms, mainly for western Wisconsin by this point as the front continues to move east. With the likely more elevated nature of the storms hail would be the main concern with this round of storms. Instability will fall off tonight and the storm concern will come to an end. In summary for eastern Minnesota, including the Twin Cities metro, this afternoon could see another round of strong to severe storms. It is farther east into western Wisconsin with the greater confidence in storms as the CI could occur in either eastern MN or western WI. If the main axis is more to the east, the Twin Cities metro could escape today without much of an impact. Current CAM guidance does favor this second wave starting in/near eastern MN/TC metro at the moment. If you are in eastern Minnesota or western Wisconsin make sure to have a way to receive warnings this afternoon and evening. && .DISCUSSION... Issued at 1244 AM CDT Wed Jun 10 2026 The next 24 hours will feature the potential for multiple rounds of severe thunderstorms across the Upper Midwest. Current regional radar mosaic highlights a line of thunderstorms stretching from Winnipeg south through the Dakotas and into northern Nebraska. A decaying MCS moving northeast out of Nebraska has begun to merge with the easterly moving convection over SoDak. These storms will then track ENE into SW/W MN shortly by 1 AM and continue through the MPX forecast area tonight. A Severe Thunderstorm Watch is in effect across portions of western MN until 4 AM. Locations further east may need an additional watch, but that will be determined at a later time. Tonight's severe threat comes in the form of a squall line that is driven by a potent 50+ knot low level jet. The squall line will have a reservoir of abundant instability to tap into with guidance suggesting 2000+ J/Kg MLCAPE present over W & C MN. A quick mesoanalysis highlights 1500 J/Kg DCAPE over W MN, 35-40 kts of effective wind shear, and steep mid-level lapse rates. While the environment will gradually wane, the dynamics associated with the LLJ should support a severe threat through much of tonight. Damaging wind gusts looks to be the main severe weather hazard with the line of storms, but a few quick QLCS tornadoes can't be ruled out within the line. The apex of the squall line should track from W MN through E MN and into W WI by daybreak. How much severe threat will the line have when it makes it into the Twin Cities and western Wisconsin is difficult to say, but there should be some severe potential despite the early morning time frame. This line has a history of producing severe wind gusts of 75+ MPH over SoDak earlier tonight and is moving into a more favorable low level kinematic environment that short lived QLCS tornadoes will be possible, especially over W MN. My immediate concern is that the merger between the north-northeast moving decaying MCS/MCV and the easterly moving squall will merge and enhance the wind threat... at least initially across far E SD and W MN. On Wednesday, we'll dry out by mid-morning in the wake of the MCS. How much convective debris is left over to limit the atmospheric recovery will ultimately impact Wednesday afternoon's severe weather potential. Guidance does limit how much additional convection fires up through the morning hours, allowing 2000 to 3000+ J/Kg MLCAPE to pool ahead of the approaching cold front. This will support a higher end severe weather environment with 40+ kts of bulk shear, sufficient lapse rates, and favorable wind profile aloft. There are a few questions that remain less certain. When and where will the initial storms develop in the afternoon? Current thoughts are for convection to fire early afternoon along I-35 before moving into W WI. Initial storms will be supercells capable of all severe modes including large to very large hail, damaging winds, and tornadoes are all possible. A favorable environment for tornadoes will be in place across W WI that will have the potential for a few strong Tornadoes. Initial supercells will quickly grow upscale into a linear complex that'll primarily pose a damaging wind threat across W WI. Severe threat wraps up late Wednesday evening and we'll look to dry out & cool down overnight. Another chance of precipitation arrive behind the cold front Thursday afternoon. Severe threat will be low, but an additional round of rain is likely. A much cooler & drier airmass will settle in Friday and stick around for the weekend. The mid level ridge will shift from the Upper Midwest downstream to the eastern CONUS. This will place zonal westerly flow over the northern Plains and Upper Midwest. Temperatures will run 5 to 10 degrees below normal (that's high temperatures in near 70) with lows in the 40s and 50s... a welcome break for the AC units across MN and W WI. A few additional chances of rain will exist, primarily on Saturday, but over a much drier pattern will persist into next week. && .AVIATION /12Z TAFS THROUGH 18Z THURSDAY/... Issued at 557 AM CDT Wed Jun 10 2026 VFR to start for all MN sites and RNH but EAU will start off MVFR-IFR with TSRA. VFR conditions likely for much of the day today. Another round of thunderstorms looks to develop in far eastern MN this afternoon then progress eastward across WI this evening. Severe weather this afternoon looks to more heavily impact the WI sites, possibly as far west as MSP. Leaning on PROB30s for E MN and WI sites and can adjust when confidence increases one way or another. VFR conditions will return post TSRA with winds turning light and variable tonight into Thursday morning. KMSP... VFR to start the period as TS have moved off into western WI. Another round of storms looks to develop over eastern MN early this afternoon and slide east. There is still some uncertainty as to whether MSP will be impacted, thus have maintained the PROB30. Even if the storms do not directly impact MSP, routes eastward of MSP will be impacted. /OUTLOOK FOR KMSP/ THU...VFR. -RA likely. Slight chc PM -TSRA. Wind SW 5-10kts becoming W 10-15G25kts.
