From Alaska to Amarillo to Atlantic City, here’s how she sees it.

Spaccio said:

“If you’re dreaming of a white Christmas, Pinkham Notch, N.H., has a 93 percent probability of fulfilling your dreams. Another high probability is Caribou, Maine, at 90 percent. If you’d rather not deal with the snow, stick closer to the coast: Lewes, Del. (5 percent), Salisbury, Md. (7 percent), Philadelphia, Pa. (8 percent), Washington, D.C. (8 percent), Atlantic City, N.J. (9 percent), Dover, Del. (9 percent).

“Looking outside the Northeast, Alaska is the clear choice for snow – Fairbanks has a 100 percent probability. Alternatively, a few cities have 0 percent probability: Augusta, Ga., Las Vegas, and Columbia, S.C.

“If you’re planning to hit the streets in New York City on New Year’s Eve, there’s a 50 percent probability of precipitation. Not as bad as Buffalo, N.Y. with 66 percent probability. If you’re looking to stay dry, weather speaking only, Las Vegas is the place to be, with only 2 percent probability for precipitation.

“These statistics are based on the previous 50 years of historical data. They provide a best estimate without looking at current conditions and forecast models. The U.S. has already  seen some snow this year, so some cities are already white. It’s also been an active period for storms, so even if the probabilities are low for your city – don’t give up hope – Mother Nature always surprises us.”
