Nashville, Tennessee – A sharp turn toward winter is expected across Tennessee beginning Thursday, as Arctic air drives temperatures well below normal and raises concerns for icy roads and possible snow through the following Wednesday.
According to the National Weather Service Climate Prediction Center, Tennessee is expected to experience a sustained period of below-normal temperatures during the Jan. 15–21 window as a large Arctic air mass settles over the central and eastern United States. While precipitation is expected to remain near seasonal averages, the cold air will allow even light snowfall to create hazardous travel conditions.
Middle Tennessee, including Nashville, Murfreesboro, and Lebanon, is expected to see some of the coldest readings of the season. Overnight wind chills could drop into the teens or lower, increasing the risk of black ice on bridges and elevated roadways along Interstate 40, Interstate 24, and Interstate 65 during morning commutes. Prolonged cold could also stress heating systems and raise the risk of frozen pipes.
In West Tennessee, including Memphis, Jackson, and Dyersburg, temperatures are expected to trend sharply colder than normal. Light snow or freezing moisture could lead to slick conditions along Interstate 55 and U.S. 51, particularly overnight and early morning. Farther east, the Cumberland Plateau and East Tennessee mountains may see enhanced snow potential, especially in areas such as Crossville, Oneida, and Gatlinburg, where elevation can worsen travel impacts.
Residents across the state are urged to prepare now by checking furnaces, insulating exposed plumbing, and stocking vehicles with winter emergency supplies. Limiting outdoor exposure during overnight and early morning hours will be important, especially for vulnerable populations and outdoor workers.
Cold-related advisories and possible winter weather alerts may be issued as confidence increases. Additional updates are expected as the Arctic pattern becomes more firmly established across Tennessee late next week.
