Nashville, Tennessee – A turn toward colder-than-normal weather during the Jan 20–24 period is increasing concern for winter weather across central and eastern Tennessee, particularly if precipitation overlaps with colder air. While snow is not guaranteed, the evolving pattern raises the risk for snow or ice, especially overnight and at higher elevations.
According to the National Weather Service Climate Prediction Center, Tennessee carries a 50–60% probability of below-normal temperatures during the January 20–24 window. Precipitation probabilities remain above normal at 40–50%, a combination that supports wintry precipitation potential when temperatures dip toward or below freezing.
In Nashville and much of Middle Tennessee, daytime temperatures may remain near seasonal levels but are expected to fall sharply at night. That setup could allow rain to briefly mix with or change to snow if systems move through during colder periods. Farther east, including Knoxville, the Upper Cumberland, and the Tennessee Valley, confidence increases that colder air could support snow or a light accumulation. The highest risk remains in East Tennessee, especially along the Cumberland Plateau and the Smoky Mountains, where colder air tends to hold longest.
Major travel corridors such as I-40, I-24, I-65, I-75, and U.S. 441 could become slick during wintry precipitation, particularly on bridges, overpasses, and mountain roads. Even light snow or ice can cause travel disruptions in the region due to limited winter treatment and rapidly changing conditions.
Residents are encouraged to prepare ahead of the Jan 20–24 window by monitoring updated weather information, checking heating systems, and planning for possible travel delays. While significant snow is not guaranteed, the evolving pattern supports the possibility of at least one impactful winter weather event across central and eastern Tennessee.
This cooler pattern is expected to persist through late week, and additional advisories or alerts may be issued as confidence in timing and impacts increases.
