The aurora may be visible in the sky again Saturday night, depending upon the weather, federal forecasters said.

Severe and extreme geomagnetic storms associated with coronal mass ejections, or solar eruptions, are likely Sunday, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center.

When the material from the sun arrives at Earth, it can cause a geomagnetic storm. During the storm, an aurora may be visible. An aurora is a natural electrical phenomenon characterized by shimmering lights in the upper atmosphere at night, usually near the northern or southern magnetic pole. They happen when energetic particles from the sun interact with atoms in the upper atmosphere.

Aurora may be visible in sky

It appears that the chances are low in Tennessee, but an aurora may be visible in the sky over the northern half of the country this weekend, and possibly as far south as Alabama.

The National Weather Service Space Weather Prediction Center has issued a watch for a severe geomagnetic storm, saying it is possible later in the day Friday and continuing through the weekend. At least seven Earth-directed coronal mass ejections are in transit, the NWS said.

However, “exact timing remains somewhat uncertain,” forecasters said.

A coronal mass ejection is a solar eruption. When the solar materials arrive at Earth, a geomagnetic storm can result.

The region’s tornado watch is in effect until 2 a.m. Wednesday, and it includes Anderson, Campbell, Knox, Loudon, Morgan, Roane, Scott, and Union counties, among others. Oak Ridge is in Anderson and Roane counties.

Roads, schools, and businesses closed as snow fell for hours in Oak Ridge. The snow began about 8:30 p.m. Sunday, and snow continued to fall at about 6 p.m. Monday.

Oak Ridge Today measured almost seven inches of snow at about 5 p.m. Monday. The National Weather Service in Morristown had forecast between four to six and six to eight inches of snow in the Oak Ridge and Clinton areas.

“Very cold air is moving in across the region with sub-freezing temperatures continuing through Thursday,” the National Weather Service said. “Temperatures Tuesday night will be around zero!”

Roads, even main streets like Oak Ridge Turnpike, had a thick layer of snow on them, with a wet, slippery surface underneath. Traffic was light when normally it would be heavy, and most drivers drove slowly and cautiously, with some turning on their hazard lights.

“With significant snow accumulations across much of the area and very cold temperatures, hazardous travel conditions may develop,” the NWS said. “Avoid travel, but if you must, use caution.”

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, cold likely, NWS says

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%.
