 Brief Description: EVENT NARRATIVE: Two farmsteads were hit near the intersection of 260th Street and County Road 10, with one receiving considerable damage. A barn was 2/3 destroyed, a harvestore silo was dented in about 70 feet off the ground, a corn crib was flattened, multiple wagons were displaced approximately 50 yards, and a wooden pole rated to 118 mph was cracked at the base. 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.
