In the United States, there is often—but not always—snow on the ground at Christmas in the northern states, except in the [[Pacific Northwest]], with [[Alaska]] the most likely to see snow on the ground at Christmas. In the contiguous United States, the highest probabilities are in the [[Upper Midwest]] and parts of [[northern New England]], along with higher elevations of the Rockies. Some of the least likely white Christmases that have happened include the [[2004 Christmas Eve Snowstorm]], which brought the first white Christmas in 50 years to [[New Orleans]]. The 2004 storm also brought the first measurable snow of any kind since 1895 to [[Brownsville, Texas]], and its [[Twin towns and sister cities|twin city]] of [[Matamoros, Tamaulipas|Matamoros]], [[Mexico]]. The Florida winter storm of 1989 also occurred immediately before Christmas causing a white Christmas for cities like [[Pensacola, Florida|Pensacola]] and [[Jacksonville]]. <!--Hard to believe, but actually, it was Miami too.--> The same storm buried [[Wilmington, North Carolina]] and the rest of southeastern North Carolina under {{convert|15|in|cm|abbr=on|order=flip}} of snow.

In the United States the notion of a white Christmas is often associated in the American popular consciousness with a Christmas celebration that includes traditional observances in the company of friends and family. "[[White Christmas (song)|White Christmas]]" is an [[Irving Berlin]] song reminiscing about an old-fashioned Christmas setting.

According to research by the [[CDIAC]], the United States during the second half of the 20th century experienced declining frequencies of white Christmases, especially in the northeastern region.<ref>{{cite news|last=Dye |first=Lee |url=http://i.abcnews.com/Technology/story?id=99617 |title=Study: White Christmases Have Become Rare |work=[[ABC News (United States)|ABC News]] |date=18 December 2003 |url-status=dead |archive-url=https://web.archive.org/web/20081210062952/http://i.abcnews.com/Technology/story?id=99617 |archive-date=10 December 2008 }}</ref> The National Climatic Data Center based the probability of a white Christmas ({{convert|1|in|cm|abbr=on|disp=or}} of snow on the ground) at selected cities upon the 1981–2010 numbers from stations with at least 25 years of data.<ref name="ncei" />
