| Brief Description: A tornado touched down just northwest of Lewiston (Winona County), then moved into the middle of town and intensified. Numerous homes along Main Street had extensive damage with broken windows, damaged roofs and downed trees. One home had the entire roof taken off, while at least 4 cars were demolished from debris landing on them. A farm southeast of town had every building destroyed, except the house. Of the 1,300 population in Lewiston, only two people sustained minor injuries. Elsewhere across southeast Minnesota, spotters and law enforcement officials reported hail up to 2 inches in diameter along with trees and power lines knocked down. | |||||||||||

| Brief Description: EVENT NARRATIVE: This EF-2 tornado touched down and tracked east-northeast, and soon crossed the path of the Blooming Prairie EF-3 that had moved north-northeast about 10 minutes earlier. A manufactured home was obliterated by the EF-2. A woman inside the home was blown about 20 feet, but was found under debris, rescued by law enforcement, and survived. The tornado continued moving east-northeast, and several outbuildings were destroyed, along with many broken trees. The tornado continued into Dodge County. 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: A small but intense supercell thunderstorm produced three tornadoes in northeast Iowa. The first tornado touched down about 4 miles southeast of New Haven (Mitchell County), south of 320th Street and between Walnut and Windfall Avenue. It tracked north, primarily in open fields, and lifted between 350th and 360th Street east of New Haven, or just west of Windfall Avenue. The tornado was rated an F1. The second tornado touched down just east of the Mitchell-Howard County line, about 4 miles south of Riceville (Howard County), and also moved straight north. It downed a few trees, but primarily crossed open fields until it reached the southeast side of Riceville. It damaged a few sheds and buildings in Riceville, with mainly tin roofing material and siding blown off. The tornado lifted in Riceville and was rated an F0. The third and most significant tornado formed about 2 miles north of Riceville, again just east of the Mitchell-Howard County line. The tornado tracked north, just east of the county line or Addison Avenue. It grew in strength and at one point was approximately 150 yards wide, hitting several homes and farms (F2 damage). One home lost the roof and all buildings. The tornado was so close to the county line that debris was thrown across Addison Avenue into Mitchell County at times. The dirt and young crops were scoured by the tornado. The tornado crossed into Minnesota just southwest of Le Roy (Mower County), hitting a home directly on the state line. The home, which was built in1900, and several buildings on the lot, were completely demolished (F3 damage). | |||||||||||

| 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.

| Brief Description: EVENT NARRATIVE: Several barns and sheds were destroyed, and structural damage was noted at some homes. Many trees were broken or snapped. This tornado was accompanied by strong rear flank downdraft winds, which also knocked down trees and damaged some sheds. EPISODE NARRATIVE: The morning of Wednesday July 14th had a complex of severe thunderstorms moving across eastern North Dakota, into portions of west-central and central Minnesota. This complex moved eastward during the morning, and intensified across portions of east-central Minnesota and west-central Wisconsin. Several waves of severe thunderstorms developed across west-central Wisconsin and began to reform westward into Minnesota by the early afternoon.
