KNOXVILLE, Tenn. (WATE) — Those looking for a white Christmas have a reason to be hopeful as the latest forecast models show colder air is expected in East Tennessee for Christmas Eve and Christmas Day.
WATE Chief Meteorologist Ken Weathers said that the chance for snow is still extremely low, but computer models that help predict what could happen are fairly consistent in forecasting highs in the low 30s and overnight dips into the teens for Knoxville on Dec. 24-25.
In an update from the National Weather Service at Morristown on Thursday, they warned that “Very cold Artic air masses will envelop much of the nation during the week 2 period, including the busy holiday season.” A graphic shared with the announcement showed a 90-100% chance of below average temperatures between December 22-28, and NWS Morristown called the system an “upcoming dangerous cold wave.“
Keep in mind that cold air is just one aspect of snow. For a white Christmas, cold air would need to be in place before the moisture arrives, Weathers said.
If the cold weather comes through after the moisture, it will rain — much like what we have been seeing lately. Currently, less than half of forecast models are showing a chance for snow, which is low. You can see that data in this image:
According to Weathers, since most of the models show low temperatures, the odds are high that it will be much colder. While there is still plenty of time to wait and watch if the snow will become more likely in the forecast, Knoxville has about a 10% chance of a white Christmas.
“We did see one just a few years ago, so it is possible, just not likely,” Weathers shared on Facebook.
