The events include a Winter Fest set for Saturday at Perrot State Park near Trempealeau; a skiing, hiking and snowshoeing event at Governor Dodge State Park near Dodgeville; and candlelight events at Lake Wissota State Park near Chippewa Falls and Whitefish Dunes State Park near Sturgeon Bay.
The DNR recommends checking its website to make sure other events are still scheduled.
In Green Bay, several of Saturday's Winterfest events have been called off.
Even colder weather is on tap for early next week. Some Wisconsin school districts are considering whether to cancel classes Monday. Wind chills in Madison, for example are forecast for minus-33 early Monday and 41 below early Tuesday.
