 Brief Description: EVENT NARRATIVE: This tornado moved from Freeborn County and into Steele County and began moving to the north-northwest, thereby missing the city of Ellendale. At about (43.9255, -93.3453), it began moving toward the northwest, and at about (43.9407, -93.3627), it actually turned some more and moved toward the west-northwest until it finally dissipated. Accounting for the change in direction, the tornado had an actual path length of 7.7 miles in Steele County. Along the way, several homes experienced significant structural damage, with one house completely destroyed and the roof removed from two others. Many outbuildings were destroyed, and hundreds of trees were uprooted and snapped. EPISODE NARRATIVE: Several strong storms developed in west-central Minnesota during the mid afternoon hours of June 17th. These storms quickly become severe and produced softball size hail northwest of Alexandria and a tornado near Leaf Valley that became the EF-4 that moved through Wadena, Minnesota. By the late afternoon, numerous thunderstorms developed across southern Minnesota along the leading edge of extreme instability. Numerous funnel cloud reports and a few brief tornado touchdowns were noted prior to 5 pm, but once the low level shear (0-1 km) increased significantly from 15 knots, to over 35 knots, strong tornadoes developed along the Iowa border. These storms along the Iowa border produced a series of long-lived tornadoes near Albert Lea, Minnesota. Very large hail also accompanied some tornadoes along with flash flooding.

 Brief Description: EVENT NARRATIVE: This tornado damaged several farmsteads. A barn was caved in on a side, roofs of hog barns were blown off, trees were snapped or uprooted, and a wood pole was snapped. 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.

 Brief Description: EVENT NARRATIVE: The tornado initially moved northeast to approximately 3.5 miles west of Conger, where at about (43.6156, -93.6015), it began to move more to the east-northeast. West of Armstrong, at about (43.6597, -93.4938), it began tracking nearly due north to just west of Manchester, where at about (43.7357, -93.4801), it began to move to the north-northwest, before dissipating 1.5 miles west of Hartland. Accounting for the changes in direction of this track, the actual path length covered by the tornado was 19.95 miles. Near 180th Street and County Road 2, a home was likely in the outer circulation of the tornado, as it sustained some roof and siding damage. A barn was also destroyed to its brick foundation and a car was also flipped over lengthwise. Some evidence of tree debarking was noted. The tornado continued to the northeast and caused extensive crop damage approximately 500 yards in width. Near County Roads 17 and 63, the tornado intensified to produce EF-3 damage, impacting a farmstead and causing the complete destruction of three swine barns and the loss of 12 head of swine. Two empty grain bins were completely blown away at this location. The house at this location had some roof damage but appeared to be northwest of the main tornado path. Approximately 100 feet northeast of the house, a 150 foot tripod style wind turbine tower was twisted and toppled. This location also marked the beginning of crops being completely raked, with only stalks of corn left, and soybean fields being almost unrecognizable. After passing through this farmstead the tornado took a more easterly path across County Road 63, and maintained EF-3 strength. After passing County Road 63, another farmstead was hit, and two empty harvester silos were toppled. The tornado continued to the northeast across County Road 4, where continued raking of the fields was noted with significant deposition of debris along the tornado path. Numerous trees were toppled at County Road 89 where it turns to the north. The tornado continued to the north-northeast, grew to 1000 yards, and around 1750 LST impacted a farmstead along County Road 12 two miles north of Conger, where EF-4 damage was observed. The house at this location was completely destroyed, as was the barn and several other buildings. Extensive tree damage was noted with nearly all branches being removed from the trunks. Debarking of trees was widespread at this location. A car was also tumbled a distance of 3200 feet, coming to rest in a field east of County Road 12. The tornado continued to the northeast across County Road 69 and County Road 46, where it weakened slightly to EF-3 intensity. As it crossed County Road 46, a house was rotated off the foundation. The tornado was approximately 700 yards wide at this point. To the north-northeast, a swine barn was destroyed with sheet metal being carried off to Interstate 90. At this same time, a satellite tornado developed and caused damage in the town of Armstrong (see separate entry). The main tornado continued to the north-northeast and was 500 yards in width. The tornado crossed County Road 74 and caused EF-2 damage to three farmsteads. One farmstead with a manufactured home was hit, resulting in one fatality and one severe injury. The tornado crossed Interstate 90 just west of County Road 14 as it grew to one third of a mile in width and re-strengthened to EF-3 intensity. Several farmsteads saw significant damage between Sugar Lake and County Road 14, with a house and two barns completely destroyed. From this point the tornado continued to the north, growing to one mile in width. Around 1800 LST, a house and barn were destroyed approximately one mile west of Manchester on County Road 25, where extensive tree and structural damage was also noted at several properties in the area. Additionally, west of this tornadic damage, a separate area of tree and structural damage was caused by strong thunderstorm winds associated with a rear flank downdraft (see separate entry). About one mile north, the tornado weakened slightly to EF-2 Intensity, where it damaged three full grain bins near County Road 29. The tornado was approximately 1300 yards at this point. Further north, at County Road 95, the tornado continued to weaken, although a farmstead still received EF-1 damage to trees and structures. Finally, the tornado continued north and began to narrow and weaken. It dissipated west of Hartland. One person was killed and 14 injured from this tornado.

These storms quickly become severe and produced softball size hail northwest of Alexandria and a tornado near Leaf Valley that became the EF-4 that moved through Wadena, Minnesota. By the late afternoon, numerous thunderstorms developed across southern Minnesota along the leading edge of extreme instability. Numerous funnel cloud reports and a few brief tornado touchdowns were noted prior to 5 pm, but once the low level shear (0-1 km) increased significantly from 15 knots, to over 35 knots, strong tornadoes developed along the Iowa border. These storms along the Iowa border produced a series of long-lived tornadoes near Albert Lea, Minnesota. Very large hail also accompanied some tornadoes along with flash flooding.

 Brief Description: EVENT NARRATIVE: A damage survey, plus photo and video evidence from storm chasers, showed that this tornado formed south-southwest of Kiester, near the intersection of 20th Street and 570th Avenue, then wrapped around another tornado (which developed about one mile west of Kiester) and dissipated. While southwest of Kiester, it did EF-2 damage to a couple farmsteads, including tree damage and destruction of several grain bins. EPISODE NARRATIVE: Several strong storms developed in west-central Minnesota during the mid afternoon hours of June 17th. These storms quickly become severe and produced softball size hail northwest of Alexandria and a tornado near Leaf Valley that became the EF-4 that moved through Wadena, Minnesota. By the late afternoon, numerous thunderstorms developed across southern Minnesota along the leading edge of extreme instability. Numerous funnel cloud reports and a few brief tornado touchdowns were noted prior to 5 pm, but once the low level shear (0-1 km) increased significantly from 15 knots, to over 35 knots, strong tornadoes developed along the Iowa border.

 Brief Description: NWS damage survey rated the tornado an F2. Tornado touched down briefly in downtown Northfield, flipping over a semi trailer truck and lifting the roof off of one business. Three-fourths mile later, it touched down again on the east side of Northfield, and then remained on the ground for 11 miles. After being in Rice County for 5 miles, it crossed Highway 19 into Dakota County and then dissipated in Goodhue County 4 miles west of Cannon Falls, for a total of 12 miles. Numerous rear flank downdraft gusts estimated at 90 mph caused damage alongside the southern periphery of tornado track. One man sustained minor injuries when he was blown from a tractor, but did not require hospitalization. A total of 8 homes received major damage, 22 more had minor damage, and a turkey processing plant was destroyed.

 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. The tornado continued east- southeast and strengthened in intensity just south of County Highway 25, where it produced EF-2 damage to multiple farmsteads. 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.

 Brief Description: EVENT NARRATIVE: A tornado caused damage on the north and northeast side of the city of Austin. Specific reports included minor tree damage, as well as debris blown into fences and bent poles on the northwest side of Austin. Several power poles were snapped off or bent along Highway 218 on the north side of the city. Several metal work buildings were heavily damaged along 243rd St, along with numerous trees and some minor roof damage to nearby homes. Large debris, such as metal dumpsters, were tossed large distances. There was straight-line wind damage noted south of the tornado path, or along Highway 218 and 4th St NW. Several homes had minor damage, with numerous trees blown over or sheared off along 236th and 237th Street directly north of downtown Austin. There was considerable damage done in Todd Park, including athletic equipment, small buildings and hundreds of trees toppled and uprooted. The north side of the park, including the northern softball fields had the most damage. There was also considerable tree damage along 21st St NE or 555th Ave, which continued into the Austin Country Club. Minor damage was noted about a half mile east of the Austin airport and about 2 miles southeast of the airport. One minor injury was reported when a man sustained scrapes and bruises when he took shelter in a shed that rolled over twice. EPISODE NARRATIVE: Severe thunderstorms were triggered along a warm front during the evening of June 17. One of the storms produced two known tornadoes, one that initially touched down near the Dodge and Mower County line, northwest of the city of Austin. The tornado then moved through far north sections of Austin to areas about 3 miles east of Austin. The worst tornado damage was considered EF2 about 3 miles north of downtown near the intersection of 243rd and 4th street northwest. The bulk of the remaining damage was considered EF0 and EF1. The tornado was on the ground from approximately 8:00 p.m. until 8:23 p.m. Path length was about 10 miles long and had a maximum width of 120 yards. Another small tornado touched down southeast of this track in open country in rural Mower County.

 Brief Description: An unstable airmass was in place over Iowa during the afternoon and evening hours of the 9th. Satellite and sounding data suggested the atmosphere was capped at about 775 mb by a warm layer of air with temperatures as high as 18 C. or more. Thunderstorms had a hard time firing off. A cold front moved southeast into the state as rich low level air with dew point temperatures in the mid 70s preceded the front. While the front moved southeast, a speed max near 100 kts in strength moved into the north central U.S. This combined with an upper level short wave helped a few of the storms break the cap. The wind profile was favourable with a strong shearing environment. Thunderstorms moved into north central Iowa and became tornadic quickly. There was basically one cell that produced at least two tornadoes as it slipped southeast into Iowa. The first tornado touched down in Winnebago County near Scarville. The tornado moved southeast across the county and advanced into Worth County by a few miles. The tornado caused crop damage and some building damage along its path. The corner of a bank building was torn off in the town of Joice in Worth County for example. The same cell produced another brief tornado touchdown near Burchinal in Cerro Gordo County near the intersection of I-35 and County Highway B-43. No significant damage was reported with this tornado. As the large cell that produced the tornado moved on, the rear flank downdraft produced high winds once again in the Scarville area. Power lines were downed and a few buildings were damaged by the high winds in the town of Scarville. High winds also struck the airport in Mason City with a wind gust of 58 MPH.
