The BL news-Life Threatening temperatures blanket the midwest
Record-breaking temperatures are settling across parts of the Midwest after a powerful snowstorm pounded the region overnight Monday, and forecasters are describing the subzero weather on the way as potentially life-threatening.
Minneapolis Public Schools announced there would be no classes through Wednesday when the region will experience frigidly low temperatures not seen in a quarter century.
Subzero temperatures will begin Tuesday but Wednesday is expected to be the worst. Wind chills in northern Illinois could fall to negative 55 degrees which the National Weather Service called "possibly life-threatening." Minnesota air temperatures could hit minus 30 degrees with a wind chill of negative 60.
The unusually frigid weather is attributed to a sudden warming way above the North Pole. A sudden blast of warm air from misplaced Moroccan heat last month made the normally super chilly air temperatures 20 miles above the North Pole rapidly rise about 125 degrees. That split the polar vortex into pieces according to Atmospheric Environmental Research, a commercial firm outside Boston
