Wider weather episode

A low pressure system in the northern plains approached Michigan's Upper Peninsula on August 28. The strengthening south wind ahead of this system drew moister air northward. Clouds increased quickly in the morning, and showers and thunderstorms broke out over western Upper Michigan by noon. One of these thunderstorms spawned a waterspout on Lake Superior near Eagle Harbor in Keweenaw County.
