The path drawn at its surveyed width of 200 yards (0.11 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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

The tornado continued from Wadena County. Trees were snapped along its path, including County Road 2 and 64 up to the west side of Deer Lake.

The wider storm

A significant, widespread severe weather outbreak occurred across a large portion of central and east central Minnesota. A powerful mid summer storm system over the western Dakotas, combined with warm moist air surging northward from the Gulf of Mexico, provided the ingredients for tornadoes, destructive winds, and large hail across parts of the Northland.

In addition, several storms in the Cass Lake and Lake Winnibigoshish area of north central Minnesota produced a large amount of one to two inch diameter hail, which is about quarter to slightly larger than golf ball size.

Began near Poplar (46.6440, -94.7859).
