Nashville, Tennessee – A clear shift back to midwinter conditions is on the way for the Tennessee Valley as a strong cooldown arrives this weekend, replacing recent mild temperatures with much colder air heading into early next week.
According to the National Weather Service Weather Prediction Center, a surge of cold air will move southeast out of the Midwest beginning Saturday, spreading across Tennessee, northern Alabama, and southern Kentucky by Sunday. High temperatures across the Tennessee Valley are expected to drop 15 to 25 degrees compared to late-week readings.
In Nashville, highs in the upper 50s to near 60 late this week will fall into the mid to upper 40s by Sunday, with overnight lows dipping into the upper 20s and lower 30s. Chattanooga and Huntsville are expected to see similar changes, with daytime highs settling into the 40s and colder mornings becoming more widespread. Farther north toward the Cumberland Plateau, some locations may struggle to climb out of the upper 30s.
The colder air will be reinforced by brisk northwest winds, making mornings and evenings feel noticeably colder. While widespread snow or ice is not the main signal at this time, the temperature drop increases the risk of patchy refreeze on bridges, overpasses, and untreated roads during early morning hours.
Residents across the Tennessee Valley are encouraged to prepare for colder mornings, protect exposed pipes and sensitive plants, and adjust travel plans for slick spots during the early commute. The colder pattern is expected to hold into early next week, with additional cold air reinforcements possible as January continues.
