A large complex of thunderstorms developed across North Dakota during the early morning of Friday, June 17th. These storms moved eastward across eastern North Dakota and produced a large area of severe winds and hail.
As the storms moved into northwest Minnesota Friday morning, a small line started to form and move southeast toward central Minnesota. Several reports of large hail occurred in Todd County before moving southward before noon. During the afternoon, a broken line of storms continued to form south and west across southern Minnesota.
The storms in the afternoon become more multicellular as they expanded further to the south and east toward the Minnesota/Iowa border by early evening. Due to the multicellular nature of the storms, downburst winds and large hail were localized. In central Minnesota, the main damage was associated with large hail, up to golf ball size at times. As they moved farther south, significant wind damage occurred, especially across southern Redwood, northern Blue Earth and western Nicollet Counties where local farms and homes were damaged. By the early evening, damage was near the Iowa border where trees and power lines were blown down. One of the storms caused a semi-truck to blow off the road on I-90 near Fairmont.
Eventually these storms weakened by the evening, but several rounds of torrential rain caused significant flooding to develop, especially near New Ulm and Courtland.
Near New Ulm, a railroad crossing was washed out on Pineapple Lane. Two roads in Courtland were washed out by heavy rains Friday night. These roads were about a mile west of 491st Street, and 506th Street was closed through 511th Street due to flooding. Apple Road, south of Highway 68, was impassable due to a mudslide. An unofficial report of 7 inches of rain fell near Courtland in less than 2 hours.
