While snow is in the forecast, NWS says little chance for a ‘white Christmas’

While the forecast calls for snow flurries on Christmas Eve, according to the National Weather Service those dreaming of a white Christmas for Carter County probably won’t get their wish.

The past couple of weeks have been active with several weather systems moving through the Northeast Tennessee region bringing with them quite a bit of moisture, according to Derek Eisentrout, a meteorologist with the NWS office in Morristown. A similar system will be moving into the area on Friday throughout the day on Saturday, but temperatures will be around 60 degrees on both days, Eisentrout said.

On Sunday, Christmas Eve, things will be cooler, with the high predicted to be in the upper 40s.

“We do have a chance of a few snow showers on Christmas Eve into the early morning hours on Christmas Day,” Eisentrout said.

While there are snow showers in the forecast for the holiday, Eisentrout said no accumulation is expected. According to Eisentrout, most of the moisture with the system will have passed before temperatures drop low enough to change the rain over into snow. Also, Eisentrout said, because Saturday’s high is expected to be around 60 followed up with a near 50-degree day on Sunday, the ground will still be too warm for the snow to lay on the ground and accumulate.

Eisentrout said there is “not a whole lot” of a chance for a white Christmas with the current weather conditions.

The last time the Tri-Cities saw what Eisentrout called a “measurable snow fall” on Christmas Day was in 2010 when 1.2 inches of snow was reported at the Tri-Cities Regional Airport.

The largest reported measurable snow for the region came in 1969 when 8.7 inches of snow fell.
