The weather in winter can be different in different parts of the world. The USA is so vast that at the same time in winter it can be freezing cold in New York City and warm in Los Angeles, California or Miami, Florida.
First, watch the winter forecast 2014-2015 USA, published on 5th August 2014: https://www.youtube.com/watch?v=jnWnNeLKdh0. As you can see the weather varies depending on the state.
As they predicted, winter is really tough! Watch the film presenting an epic snowfall for US and Canada with 15 dead after massive US snowstorm. About 345,000 homes and business remained without power as the U.S. Northeast and Canada dug out from a blizzard that dumped up waist-deep snow. You can see all that here: https://www.youtube.com/watch?v=OtpAUqoJ8Vw
