Chances of Snow for Christmas at USA Cities





Among America's large cities, only one has a really good chance of having a white Christmas. For most cities the odds of seeing any snow at Xmas are pretty slim.

The major urban area with the best chance of enjoying a traditional Christmas landscape is Minneapolis — St Paul Minnesota, where there's a 74 percent probability of having at least one inch of snow on the ground. In fact, the city is likely to have three or more inches of snow.

Three other large cities are also more likely than not to have some snow around on December 25: Buffalo, Rochester and Salt Lake City. Rochester even has a fifty-fifty chance of seeing fresh snow falling at Xmas.

The table below gives the probabilties of Christmas snow for 51 US cities.

While less than even, the odds of snow blanketing Milwaukee, Cleveland or Denver on Dec 25th are still pretty high, at 40 percent or more. For Pittsburgh, the chance of snow is nearly one in three, for Columbus about one in four and for Boston almost one in five. At New York, Cincinnati, Louisville and Baltimore, the likelihood of a snowy Xmas runs close to one in ten.

Not surprisingly, for many cities in Texas, California and Florida, there's zero chance of a white Christmas. At a few cities, such as Las Vegas and New Orleans, snow on Dec 25 isn't entirely impossible, but would make an astonishing event as the odds of it happening amount to much less than one percent.
