"I feel from the plains eastward, more people than normal will have a white Christmas," said senior meteorologist Joe Bastardi, Accuweather's chief long-range forecaster.
Weathermen -- and bookies -- are even betting that England, which has had unusually early cold and snowy weather already this year, will have a winter wonderland on Christmas Day.
"As it stands, this year we've got the shortest prices we've ever had, the most number of bets we've ever had," said Rupert Adams of William Hill, a British sports betting website. "It's literally a wild kingdom at the moment. Over 10,000 bets on whether it will be a white Christmas in the U.K."
At the beginning of December, Bastardi said he was predicting snowstorms that would dump snow on the eastern half of the United States later in the month. He predicted temperatures would remain cold enough to keep the while stuff around until Christmas. Sounds eerily familiar to when an enormous blizzard, dubbed "Snomageddon," dumped several feet of snow on the Northeast last year.
Typically a quarter to a third of the United States is blanketed with white over the Christmas holiday, but Bastardi is predicting about half of the country will see snow.
Long range forecasting is a huge business and everyone from big company executives to farmers and even brides trying to plan their weddings months out are among those buying three million copies a year of "The Old Farmer's Almanac." It's been predicting the weather for 219 years.
"A perfect wedding day. Thanks for your accurate prediction," read one letter from a happy bride to the Almanac staff.
"Ours is the oldest continuously published periodical in North America, and by virtue of its popularity, we can only guess it's the most accurate, reliable and entertaining," said Janice Stillman.
Stillman is only the 13th editor of "The Old Farmer's Almanac" since it's been in publication. Its offices are located in Dublin, New Hampshire, where they have a copies of some of the first editions.
"This is 1793," Stillman said as she pointed out a very worn book. "1793 is the first edition. It was produced in 1792."
Among several useful facts and figures -- times for sunrise and sunset, ocean tides, even poetry -- the thick book also contains a year's worth of weather, region by region.
"The almanac we put together in one year's time, so our weather forecasts, which are in each almanac, are predicted 18 months in advance," Stillman said.
So how do the almanac writers make their weather predictions months in advance when TV weather forecasters have trouble figuring out tomorrow's weather? Stillman said it's just science.
"We use scientific disciplines," she said. "We use solar science, which is the study of activity on the sun and in particular the sunspots. We use climatology, which is the study of prevailing conditions over time and we're talking decades, centuries and even longer. We use meteorology, which is the study of the atmosphere and the oscillations and ocean temperature and such as that."
