The tornado that touched down in Gordon, Wis., Thursday lifted a few minutes after it formed, but reached wind speeds up to 110 mph and devastated trees in its path, said the National Weather Service in Duluth, which issued a follow-up report on the weather phenomenon on Monday.
The tornado appeared roughly 56 miles southeast of Duluth and was born out of a "supercell thunderstorm" that began in nearby Chaffey, Wis. — 27 miles northwest of Gordon. Following the tornado, the storm moved across southern Bayfield County and dissipated near Namekagon.

The survey of the tornado "picked up the damage path where it crossed Cabin Lane several hundred yards west of Sand Road," the Weather Service said, describing numerous uprooted and broken softwood trees at the tornado's origin.

The damage was consistent with wind speeds of up to 85 mph and intensified from there, reaching "EF-1 intensity," south of the intersection between the aforementioned roads. West of nearby Schaefer Road, the tornado "cut through trees" in a path approximately 80 yards wide and a half-mile in length, with wind speeds reaching 100-110 mph, the Weather Service said.
"The tornado weakened quickly after crossing Schaefer Road," the Weather Service said.
An EF-1 tornado is considered moderate on the tornado spectrum, the Weather Service said, with the most intense EF-5 tornadoes reaching more than 200 mph.
