Dreaming of a White Christmas?

It is less likely than ever in many parts of the country, read here for some exact figures, based on data since 1948. Here is the geographic distribution of the changes, snow is less likely in the east but more likely in some mountain states:

The decrease in the number of snow days has been especially pronounced east of the Mississippi River, where 117 of 125 stations reported an average of five fewer days with snowfall.

“Five fewer days of snowfall over a 30-day period may not seem all that significant until you consider that, in many regions, snow days occur relatively infrequently,” Kaiser said.

One region that is more wintry between the holidays, however, extends from the Central Rocky Mountain states (Utah, Colorado and Wyoming) eastward into the Central Plains (mainly Nebraska), where the number of days with snow has increased significantly.

“The area across the Central Rockies and Central Plains is the one part of the country that is bucking the trend, with a few stations in Utah and Colorado seeing nearly 10 more days with snowfall,” Kaiser said.

The researchers caution against thinking that this is a tale of global warming, one way or the other.
