CEDAR RAPIDS, Iowa (KCRG) - The prospects of a white Christmas are looking awfully slim. As we’ve mentioned before, though, the long-term odds in any given year are only about 50-50, and the past couple of years have had at least an inch of snow on the ground on December 25.
Snow depth data are a little tricky – they’re not as straightforward as temperatures, since there’s some room for error that thermometers don’t have. For example, snow can blow around or melt or compact, or it can be measured incorrectly. However, we can still use the information to get a decent sense of historical weather.
This is a chart showing how much snow was on the ground each Christmas going back to 1925. Only three years had at least 10 inches of snowpack: 2010, 2000, and 1951. 2010 was the big winner with 14 inches! About 40 years were bare, with another dozen years coming in with just an inch. In reality, it’s more common to have little or no snowpack on Christmas than it is to have a bunch.
