Knoxville, Tennessee – Drivers across East Tennessee should prepare for dangerous travel conditions late tonight into Thursday morning as falling temperatures allow wet roadways to refreeze, creating patchy black ice across the region.
According to the National Weather Service in Morristown, temperatures are expected to drop into the 20s overnight. Any remaining moisture from recent rain or melting snow will freeze, leading to slick and potentially invisible ice on road surfaces. The greatest risk will be on untreated roads, bridges, overpasses, and shaded areas that cool more quickly after sunset.
The black ice threat spans a wide portion of East Tennessee, including Knoxville, Morristown, Oak Ridge, Maryville, Sevierville, Johnson City, Kingsport, and Chattanooga. Major travel corridors such as I-40, I-75, I-81, I-640, and I-24 could develop isolated slick spots overnight, especially near river valleys and elevated terrain.
Commuters heading out early Thursday should be especially cautious, as black ice is difficult to see and can catch drivers off guard at highway speeds. Secondary roads, rural routes, and neighborhood streets are most likely to be affected, though ramps and bridges along interstates may also become hazardous.
Emergency officials urge motorists to slow down, increase following distance, and avoid sudden braking or sharp turns. If possible, delaying travel until temperatures rise later Thursday morning may reduce risk. Pedestrians should also watch for icy sidewalks and parking lots.
School districts and local agencies will be monitoring conditions closely, though widespread closures are not expected at this time. Even so, a few slick spots can be enough to cause accidents during the morning commute.
Temperatures are expected to rise later Thursday, allowing ice to melt and road conditions to improve. Until then, residents are advised to remain alert and stay informed. Additional statements may be issued if conditions worsen overnight, but for now, patchy black ice remains the primary concern through Thursday morning.
