A White Christmas is looking more likely in the Tri-Cities

Weather

(WJHL)- Historically, our chances of a White Christmas aren’t that great in the Tri-Cities area. Since 1937, there have only been 9. That’s a 10.8% chance of a White Christmas in a given year. In other words, we usually have one every 9 or 10 years on average.

Each person may have a slightly different belief of what constitutes as a White Christmas. The National Weather Service in Morristown says for us, it’s at least one inch of snow on the ground and/or at least one inch of snowfall recorded on Christmas.

Models are coming together and showing the likelihood of snow on Christmas Eve into Christmas Day. Now will we have enough to verify the definition of a White Christmas? Most of the snow will fall on Christmas Eve. The Tri-Cities will likely see a couple inches. While higher elevations and the Cumberland Plateau may see 3-7″. These are subject to change, stay with Storm Team 11 with the latest updates.

As far as timing, models are in good agreement that rain moves in first until about lunchtime. Then the cold air plunges in. Snow begins in the afternoon for most.

After the main line of precipitation, snow showers will be possible for the rest of the night Christmas Eve and even into Christmas Day.

Cold air is no question for the Tri-Cities come Christmas Day. High temperatures will likely remain in the teens and 20s. Wind chill values will be brutal in the single digits around the Tri-Cities and even below zero!

Another impact is strong winds. There is a High Wind Watch going into effect tomorrow for the east Tennessee mountains and nearby foothills. It will be windy all around, but gusts up to 60 mph are possible in the watch locations.
