Dangerously cold wind chills could drop to between 0 and -10 degrees Fahrenheit in the Tennessee Valley tonight through Sunday morning and even lower, between -10 and -25, in the mountains, forecasters said. And there is a chance of snow near Oak Ridge this week.
Those not dressed appropriately overnight could be susceptible to hypothermia or frostbite. Exposed pipes may freeze, and the cold poses a threat to outdoor pets and livestock, according to the National Weather Service in Morristown.
The NWS said exposed pipes should be insulated or covered, and pets and livestock should be brought in or provided shelter. Forecasters also recommended checking on the elderly or those without sufficient heat.
“Dress appropriately if outdoors, especially children waiting for the school bus,” forecasters said Saturday afternoon.
The Weather Service said dangerously cold arctic air is moving into the region this weekend, with winter weather likely early next week.
The low near Oak Ridge was forecast for 15 on Saturday night and Sunday morning, with a north wind of around 10 mph.
The high Sunday is forecast at 29 under mostly sunny skies, with wind chill values between 5 and 15 and a north wind between 5 to 10 mph.
There is a chance of snow from Sunday night through Wednesday.
On Sunday night, the NWS said, there is a 50 percent chance of snow, mainly after 1 a.m. Skies are expected to be mostly cloudy, with a low around 18, and the forecast calls for a northeast wind around 5 mph.
The forecast calls for an 80 percent chance of snow on Monday, with a high near 30 and a northeast wind around 5 mph becoming calm in the morning. The chance of precipitation is 80 percent, and a new snow accumulation of three to five inches is possible.
