ST. LOUIS (KMOX) – For many people, it just doesn’t seem like Christmas without some snow on the ground.
The nostalgia-free analysts at the National Weather Service office in Weldon Spring keep statistics on virtually everything, including the odds of snow falling on Christmas Day.
“In the St. Louis area, our chances of having a white Christmas is right around 20 percent or so,” meteorologist Scott Truett explains.
Truett says there is a slight chance for some flurries early Christmas Day, what he calls “a mood snow,” but that doesn’t count as a white Christmas, according to NWS guidelines.
“Our definition of a white Christmas is if there’s an inch of snow or more on the ground at 6 a.m. on Christmas morning,” Truett says.
By that measure, only one-in-five Christmases in St. Louis can be considered “white.”
This year marks the 100-year anniversary of the snowiest Christmas here; 9.2 inches fell back in 1913.
The coldest Christmas in St. Louis occurred 30 years ago when the temperature fell to -13 degrees in 1983.
