(SOUTHERN COLORADO) — A source from the National Weather Service defines a white Christmas as having one inch of snow (or more) on the ground by Christmas morning. Different cultures and regions may have different definitions, but for now, that's the one that we will compare the area to. The map above, from the National Weather Service, shows what the typical chances are of a white Christmas across the United States. Notice, there is a pretty sharp and clear line around the midpoint of the nation. States south of Kansas, Missouri, and the Great Lakes region generally don't have the best chance for snowfall on Christmas. Colorado is in a unique position. The Rocky Mountains almost certainly have a white Christmas every year but the foothills and lower elevations are a bit trickier. The terrain and climatological factors of Colorado often work against areas along I-25 and to the East. One of the big limiting factors is moisture. Colorado is well known for being abnormally dry. Let's talk specifics. For Colorado Springs, the National Weather Service notes that there is historically about a 30% chance for a white Christmas. Data, dating back to the 1950s, shows 49 out of nearly 70 holidays without snow. That is a pretty significant chunk of Christmas time without at least an inch of snow on the ground. The last white Christmas for the area happened back in 2012 - which was twelve years ago now! Similar statistics exist for folks in Pueblo. The last white Christmas was recorded twelve years ago with a more significant amount of snow occurring in 2011. The Pueblo area historically only sees a white Christmas about 20% of the time. Lower elevations and even drier air often inhibit adequate dynamics for snowfall. This year, snowfall on Christmas isn't out of the question - especially if you have a bit more of a loose definition of what a white Christmas is. Current models are indicating some incoming energy on Wednesday. Timing has been inconsistent with recent model runs but the strength appears to be on the lower side. As of Sunday evening, the FOX21 Storm Team is watching for snow potential at the lower elevations sometime in the evening on Christmas Day. The mountains will likely see snow throughout the morning and afternoon.
