Many of us are wondering whether we will have a white Christmas or not. The snow-free record streak continues at 292 days as of Wednesday. With a streak like that, it doesn't look very promising for a white Christmas, but let's discuss probability.
The National Climatic Data Center has put together a chart that uses stations with at least 25 years or more of snow data. The following chart using the 1981-2010 data shows that in our part of the country we have a white Christmas less than 40 percent of the time.
In Omaha, the probability of a white Christmas (an inch or more of snow on the ground) is 33 percent (39 out of 119 years of snow records through 2011 using current data available).
Barbara Mayes, National Weather Service meteorologist in Omaha says, "In any given year, our chance of a white Christmas is around 40 percent. This year, the chance of a white Christmas is getting lower as no snow is in the forecast."
