 Brief Description: A tornado touched down on the western edge of Sylvan Lake and moved quickly northeast. It produced F0 damage to some farms and rural residences in Hassan Township before strengthening and entering the northwest corner of Rogers. It gained F2 status briefly as it moved through a residential neighborhood in Rogers, where it took the life of a 10 year old girl in a home. A home weather station 2/3 mile southeast of the tornado at this point measured 65 mph inflow winds. The tornado crossed Interstate 94 and entered another neighborhood, where F1 damage was produced. One house with significant damage had a home weather station in the back yard. Once the data were retrieved, its peak gust was found to have reached 105 mph. The tornado then moved into the northern tip of Dayton, alternating between F0 and F1 damage, then exited Hennepin County, crossed the Mississippi River and entered the city of Ramsey in Anoka County (see separate entry). The maximum width in Hennepin County was 100 yards, although its maximum width in Anoka County was only 25 yards. F10PH

 Brief Description: EVENT NARRATIVE: The tornado touched down on the eastern side of Lino Lakes, at the eastern shore of Peltier Lake. The tornado felled trees and lifted boat docks, then tracked east and crossed Interstate 35E. As this occurred, a few barns, grain bins, and silos were damaged. The tornado then intensified as it moved into northwestern Washington County and a subdivision (Creekview Preserve), about two miles north of downtown Hugo. It was at this point (around 16:01), that the twister caused EF-3 damage. The tornado dissipated in the eastern portion of Hugo, just north of Irish Avenue and 140th Street. Seven hundred and ninety four homes, including mobile homes, were affected by the storm in some way. A total of 91 homes sustained minor structural damage, numerous broken windows, and damage to small sections of roof. Twenty seven homes were destroyed, totally collapsed, or not economically feasible to repair. A two year old boy in Washington County (see corresponding entry) died after being blown out of the first floor of his home in Creekview Preserve. A 62 year old woman in Washington County died an indirect death due to a heart attack during cleanup in Hugo a few days later. Some important information provided by the Pioneer Press, Star Tribune, and other local newspapers. EPISODE NARRATIVE: A cold front was the catalyst for numerous reports of severe weather on this date.

 Brief Description: EVENT NARRATIVE: The tornado touched down on the west side of Courtland, near Highway 14. The tornado produced EF-1 damage in the town of Courtland, where numerous trees were uprooted and many large tree branches were downed.

Damage included total destruction of a barn just west of the intersection of 511th avenue and County Highway 25. Widespread tree damage and snapped electrical transmission lines were also noted. EPISODE NARRATIVE: During the morning of Friday June 25th, a small complex of thunderstorms developed across west-central Minnesota, and quickly moved eastward across southern Minnesota. Isolated severe weather occurred with these storms in west-central Minnesota during the morning hours. During the afternoon, a larger complex of storms developed across western Minnesota, and moved quickly across portions of central and southern Minnesota during the evening. Damage was extensive as several bow echoes, supercells, and squall lines raced across the area. There were numerous reports of structural damage to farms and homesteads, very large hail, and very large trees blown down. Softball to baseball size hail was reported near New Ulm, Minnesota, with several reports of wind damage throughout southern, and east-central Minnesota. Several significant tornadoes occurred in portions of south central Minnesota during the late afternoon, and early evening hours. Two separate severe storms moved across the Twin Cities area, one produced minor damage with hail in the late afternoon, but the second that occurred in the early evening caused more straight-line wind damage throughout the area, along with flash flooding.

EPISODE NARRATIVE: During the morning of Friday June 25th, a small complex of thunderstorms developed across west-central Minnesota, and quickly moved eastward across southern Minnesota. Isolated severe weather occurred with these storms in west-central Minnesota during the morning hours. During the afternoon, a larger complex of storms developed across western Minnesota, and moved quickly across portions of central and southern Minnesota during the evening. Damage was extensive as several bow echoes, supercells, and squall lines raced across the area. There were numerous reports of structural damage to farms and homesteads, very large hail, and very large trees blown down. Softball to baseball size hail was reported near New Ulm, Minnesota, with several reports of wind damage throughout southern, and east-central Minnesota.
