What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

Isolated tree damage was noted near the initial touchdown location, but the damage became more concentrated and more intense as the storm approached Constance Lake. Low end EF-1 tornado damage was noted, as the trunks of several trees were snapped at locations on both sides of the lake. An intermittent damage path continued further north, with damage to trees and a small lean-to shelter. The tornado dissipated near the intersection of 85th St NE and Cahill Ave.

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 Buffalo (45.2010, -93.8680).
