Brown Christmas doesn't have the same ring

So according to QI, England had a grand total of 4 white Christmases in all of the 20th century. However, there was an entire decade of very cold winters early in the 19th century, which just happens to have coincided with Charles Dickens' formative years - 6 of his first 9 Christmases were white. It was Dickens' portrayal of white Christmases that led the rest of us to associate the day with snow.
