Episode Narrative A very hot and humid day occurred across southern Minnesota, and western Wisconsin Friday, July 1st. A frontal boundary held across the southwest part of the state, then northeast across east central Minnesota, and into portions of west central and northern Wisconsin.
During the afternoon, a large thunderstorm complex developed across southeast South Dakota, along this frontal boundary and moved into far southwest Minnesota. Several long duration super cells and bow echoes occurred along a path from the southwest, to the northeast across southern Minnesota, and into west central Wisconsin. A secondary area of thunderstorms moved across southern Minnesota, and into west central Wisconsin during the evening hours and produced additional severe wind gusts and damage.
Most of the damage was associated with large trees blown down.
Event Narrative Numerous reports of downed power lines and trees occurred across Polk County from near Osceola, north and east to Dresser, Wanderoos, Balsam Lake, Milltown, Luck and Clam Falls, Wisconsin. A spotter measured a wind gust near Wanderoos at 59 knots.
