Snowstorms were in the forecast for Friday, and the Tennessee Department of Transportation was working to keep the roads safe the night before.
Mark Nagi with TDOT said that they were placing a light layer of salt down as rain and snow began to fall. Temperatures were above freezing when they began preparing for the snow, and light rain was falling in many areas. However, officials warned temperatures could drop below freezing Thursday night.
Weather experts were expecting rain to transition to wet snow overnight and into Friday morning, creating a potential for slushy roads in the morning. Many East Tennessee schools were delayed or canceled by Thursday evening, due to inclement weather.
Officials recommended commuters check the weather before leaving home, give themselves extra time to reach their destinations and to check road conditions before heading out.
Heavy snow was also predicted in the mountains, with a chance for a wintry mix during the day in the Valley.
Refreezing was possible Friday night into Saturday morning, as colder air was expected to move in.
