The wider storm
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.
Began near Ellendale (43.8481, -93.3260).
