KNOXVILLE, Tenn. (WATE) — Dangerously cold wind chills are expected to move into East Tennessee late tonight and continue through the weekend.

This weekend, the WATE Storm Team is anticipating frigid temperatures and below zero wind chill values. Meteorologist Victoria Cavaliere shared that all of East Tennessee is under a Wind Chill Warning which will go into effect late Thursday night.

When talking about wind chill, it is important to note that it is different than the actual temperature found in forecasts as it also takes into account some other factors.

“Wind chill tells you how cold it feels outside. It takes into account the actual temperature, wind speed, the human face model and how the body loses heat.” Cavaliere explained.

The National Weather Service’s website says that the temperatures heading into the weekend will likely be the coldest seen in this area in the month of December since 1989.

From Friday morning through much of Saturday wind chill values are expected to be below zero. The higher elevations could have wind chill values as low as 25 to 40 below zero, Cavaliere said.

Cavaliere also shared that these wind chill values are dangerous and unprecedented for our area. Cold like this can result in frost bite and hypothermia. She added that people can prepare for the frigid weather by making sure to dress in layers, cover exposed skin, and limit time outdoors. Also be prepared to bring plants and pets indoors and make sure to protect your pipes.

“Additionally, this system may result in power outages. In order to prepare for the potential for power outages make sure to have a winter weather kit which includes food, water, a flashlight, medication, etc. If you do lose power, be sure to close the blinds to keep in heat, close off rooms so that you don’t waste heat, wear layers of loose but warm clothing, put rags and towels in cracks of doors and be sure to eat and drink.” Cavaliere said.
