A life-threatening cold spell began to ease its grip on the northeastern United States on Saturday, but only after a new national windchill record was set in New Hampshire.

The record was set at Mount Washington Friday night when it felt like minus 108° F thanks to a temperature of minus 46° F and wind gusts of 127 mph.

Wind chill records are not historically tracked as closely as temperature records, but the mark would beat what most meteorologists believe to be the US record (minus 105° F in Alaska).
