The episode as NWS DLH wrote it up.
A few isolated thunderstorms developed ahead of a warm front during the evening of the 28th. While most storms were not severe, one storm did knock down a few power lines near Gordon leading to power outages in the area.
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 Duluth, MN wrote its last area forecast discussion before the first event at Jun 28, 11:29 PM CST, 15 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Duluth MN 1229 AM CDT Sun Jun 29 2025 .KEY MESSAGES... - Several opportunities for severe thunderstorms through Sunday evening - mainly south of US 2. - Elevated flooding threat due to heavy rainfall potential through early Monday - mainly south of US 2. - Less active weather next week. && .DISCUSSION... Issued at 234 PM CDT Sat Jun 28 2025 A boundary will set up just south of the Northland this afternoon, becoming the primary focus for late-day severe weather across Northeast Minnesota and Northwest Wisconsin. While current radar shows a weakening Mesoscale Convective System (MCS) across southern Minnesota, its associated outflow boundary is pushing into northwest Iowa and eastern South Dakota. We anticipate the low-level air mass will rapidly recover in the wake of this convection, leading to rapid and intense thunderstorm development by late afternoon. Even with some disorganized directional shear shown in model soundings, convective initiation is still expected. One thing to note is that surface dewpoints have climbed into the low 70s across northern Minnesota where less cloud cover has allowed temperatures to climb into the 80s. Current suite of CAMS drives the convection closer to the W to E boundary south of US 2, but they may be getting the MCS influence a little off, so thinking the threat does indeed extend northward to the International Border for strong to severe storms. Influence from Lake Superior should decrease the wind threat along the North Shore where more stable air resides. Low LCLs and a little low level curvature to the hodographs will maintain a tornado threat south of US 2. Initially, any storms that form will be elevated, making large to very large hail the primary threat, potentially continuing into the early evening. After 4-6 PM CT, storms are expected to become surface-based, bringing a more combined damaging wind and large hail threat. The main area of concern will remain south of Wisconsin Highway 77 in northwest Wisconsin and east of the Brainerd Lakes region, with storms generally moving to the east. High-resolution models continue to suggest another storm complex forming later this evening, potentially lasting into the overnight hours. Additionally, a very moist airmass moving into northern Wisconsin could trigger another round of heavy rainfall (1-3 inches). This is particularly concerning for areas that recently saw 2-4 inches of rain just a few days ago. Well be closely monitoring this flooding threat and will issue headlines if confidence increases in significant rainfall overlapping previously saturated areas. Another disturbance (vorticity lobe maxima) will move through the region Sunday as a broad mid-level trough pushes eastward. This will bring another round of thunderstorms on Sunday, primarily focused on northwest Wisconsin during the afternoon and evening hours. After a seasonable but humid weekend with high dewpoints, westerly flow will enter the region Monday, bringing lower dewpoints and seasonable temperatures. Expect continued scattered diurnal thunderstorm chances mid to late next week. Looking ahead to the holiday weekend, the pattern currently slightly favors a warmer trend for northern Minnesota, with cooler flow over northern Wisconsin. && .AVIATION /06Z TAFS THROUGH 06Z MONDAY/... Issued at 1229 AM CDT Sun Jun 29 2025 Thunderstorms are expected at HYR within the next 3 hours. IFR conditions and gusty and erratic wind gusts approaching 40 kt are expected. Higher winds approaching 50 kt can't be ruled out, though they don't appear likely at this time. Aside from that, it's looking like thunderstorm activity should be pretty much over elsewhere tonight. Some fog may be possible at places like DLH/HIB, though there isn't a terribly strong signal from models. Skies are expected to become partly cloudy after sunrise with winds becoming westerly. The main concern for Sunday afternoon will be the potential for redeveloping scattered thunderstorms, which would most likely affect HYR (~60% chance). && .MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/... Issued at 201 PM CDT Sat Jun 28 2025 Aside from thunderstorms from now through Sunday evening, winds should be fairly light with decreasing wave heights.
