Areas in the upper Midwest experienced temperatures of minus 10 as yet another snowstorm appears to be fast approaching, causing schools to close and killing one man.
At about 8 a.m. Tuesday, temperatures were minus 40 in International Falls and minus 35 in Roseau. Farther south, Minneapolis hit 18 below zero with a wind chill of 32 below and black ice was blamed for numerous accidents.
The cold weather left streets with ice and snow that caused numerous traffic accidents from Minnesota to Indiana, where police said a truck overturned and spilled 43,000 pounds of cheese, closing a busy highway ramp during the night in the Gary area.
The cold burst of weather was also responsible for at least one death on Tuesday.
A 51-year-old man in northern Wisconsin died from exposure after wandering from his Hayward home early Tuesday, authorities said.
He was first reported by son who reported him missing as he knew the father would often sleep walk. Police then followed his footprints in the snow to find him about 190 yards from his house, Sawyer County Chief Deputy Tim Zeigle said.
Schools were closed because of the cold as far south as Iowa, and authorities in Grand Rapids, Mich., issued an extreme cold weather alert.
