The average temperatures in 2022 were above the normal temperatures in East Tennessee, but there were record cold temperatures reported on Christmas Eve, the National Weather Service said.

The number of cold hours around Christmas in late December might have seemed long, but it was not a record-breaker, the NWS said.

“The arctic front that ushered in this outbreak of cold weather moved through during the early morning hours on December 23,” the NWS said. Between then and the end of the cold streak, several locations recorded more than 100 consecutive hours at or below freezing (32 degrees Fahrenheit). Wise, a city in southwest Virginia north of Tennessee’s Tri-Cities, reported 107 hours below freezing, the NWS said. That’s equivalent to about 4.5 days. Oak Ridge was below freezing for 106 hours and Knoxville for 104 hours, both also close to 4.5 days.

Snow and cold temperatures are likely in Oak Ridge on Thursday, the National Weather Service in Morristown said, and many schools in the area, including in Oak Ridge, are closed.

Here is the NWS forecast for the Oak Ridge area on Thursday, when the high is expected to be 36 degrees Fahrenheit, with a mostly cloudy sky and a wintry mix of precipitation:

  • Rain, snow, and sleet before 4 p.m. Thursday.
  • Rain between 4 and 5 p.m.
  • Rain and snow after 5 p.m.

The chance of precipitation is 100%, but the Weather Service does not expect much snow or sleet to accumulate. The NWS said it has “moderate confidence in the start time for snow since minor changes in temperature can affect when rain turns to snow.”

But this evening, there could be one to two inches of snow that accumulate, the NWS said. Snow is likely mainly before 8 p.m., the forecast said. The chance of precipitation is 60%.
