Abstract : The duration of temperature as low as -60F over North America is presented. Data from 106 stations across the United States and Canada were tabulated to provide the longest period of temperature at or below eight 'threshold' temperatures in ten years. Also depicted are expected (approximately 50 percent probability) duration of six 'threshold' temperatures during any single winter season. Durations at or below -60F have exceeded 48 hours in the Yukon, but the longest duration of -40F over the contiguous United States was only two hours along the Canadian border of North Dakota.
