The snowstorm that hit the East Coast with frigid, wind-whipped whiteness and ice that wouldn't melt seems to pick a different bull's eye target each day, with a wind chill close to minus 100 at the top of New Hampshire's Mount Washington vying for world's coldest place with the Canadian town of Armstrong, Ontario.

On Saturday, jaw-clenching temperatures throughout the Northeast hit Burlington, Vermont, at minus 1 and a wind chill of minus 30. Both Philadelphia and New York were shivering at 8 degrees.

And in Hartford, Connecticut, a brutal cold of 10 degrees yielded a wind chill of minus 20. Weather experts say that Mount Washington in New Hampshire could hit -100f with wind chill - colder than the surface of Mars.

Winds swirled Mount Washington at more than 90 mph at a temperature of minus 37 degrees and a wind chill of minus 93 on Saturday.

Meanwhile, New York City is projected to experience its worst winter cold of the year, with temperatures expected to hit 3 degrees by night fall with a windchill between -10 and -20 degrees, according to NBC News.
