GREEN BAY, Wis. (AP) — The death of a man found on a sidewalk outside his Milwaukee home Friday could be the result of bitterly cold temperatures that were expected to plunge even further over the weekend, officials said.
The 66-year-old man was found on the sidewalk Friday morning with a core body temperature of 45 degrees, according to the Milwaukee County Medical Examiner's Office. He was pronounced dead shortly before 8 a.m., authorities said. An autopsy to determine an official cause of death was pending. Overnight temperatures in Milwaukee were in the minus teens.
The deep freeze in Wisconsin was already breaking records ahead of the weekend, even before the coldest air of the season arrives. A record low temperature was set in Green Bay Friday morning, where the mercury dipped to minus 18. The National Weather Service says that tops the 17 below mark last recorded in 1979. Antigo also set a record Friday at minus 25.
School administrators in Wisconsin weighed a decision on whether to cancel classes on Monday due to the dangerously cold weather that's expected to arrive. The coldest air of the season is predicted for Sunday night through Tuesday. Bitter cold wind chills are expected to dip to 35 below to minus 50.
In Minnesota, where high temperatures are not expected to get past the minus teens, Gov. Mark Dayton said all public schools statewide would be closed Monday. It will be the first time that a Minnesota governor closed schools in response to cold weather since 1997.
Life-threatening temperatures that could linger through Tuesday, according to the weather service. Lows on Sunday night could range from minus 10 to minus 25, with wind chills of minus 30 to minus 40. On Monday, highs will still be below zero, ranging from minus 5 to minus 15.
Wisconsin Emergency Management says those conditions could lead to major trauma in a matter of minutes. It says frostbite can occur on exposed skin in less than 10 minutes, and people are especially vulnerable to hypothermia, which is marked by shivering and confusion.
