While a Pakistani city was busy banningValentine’s Day, Mother Nature put her own chill on the holiday closer to home: Low-temperature records were shattered in parts of the Northeast, with one area in New York registering a wind chill of minus 114 degrees Fahrenheit.
The Big Apple felt the freeze, setting a February 14 record of -1° F (actual temperature). But that was downright balmy compared to Watertown, N.Y., 300 miles north, where the mercury dipped down to -37° F.

AccuWeather.com writes that the arctic temperatures were assisted “by a southward shift in the polar vortex,” which “is a storm that is typically centered near the North Pole and tends to keep the coldest air trapped in northern Canada. Occasionally, this storm weakens or shifts enough to allow frigid air to plummet southward into the United States.”
