Meteorologists called it "weather whiplash" – a drop of roughly 50 degrees in a matter of hours that took temperatures from 55 in Central Park on Monday morning to a record low of 5 overnight and an expected high on Tuesday of only 10. The last time temperatures in New York fell that much in such a short time, Warren G. Harding was in the White House…David A. Robinson, New Jersey’s state climatologist and a professor at Rutgers, said the huge one-day temperature swing was not particularly surprising given the other weather extremes of recent weeks. "We’ve had this amplified pattern for the past six weeks or so," he said. "With it, we’ve had record warmth. We’ve had record cold. The fact is it’s happened, and we don’t know exactly why."
