KNOXVILLE, Tenn. — A developing low pressure system will track across the Southern Appalachians Sunday bringing East Tennessee wet and wintry weather.
This system will have a pocket of colder air causing the rain to become mixed with wet snow at times. Lows Sunday morning will be above freezing in the middle 30s in the Valley. Higher elevations, including the Mountains, Foothills and Plateau, will see temperatures closer to freezing which will cause the rain to change to all snow in these locations Sunday morning into mid-day.
Meanwhile, mainly a cold rain mixed with wet snow at times is expected for the lower elevation Valley, including Knoxville. Little to no snow accumulation is expected in the Valley areas. If anything did accumulate, it would likely be confined to elevated grassy and deck surfaces. Highs will be in the upper 30s to near 40 degrees, minimizing the impacts in the Valley.
However, more moderate to heavier snow is expected for the Mountains and Foothills, as well as the Plateau up into Southeast Kentucky. These areas are expected to have the higher impacts from the wintry weather. For the Mountains and Foothills, 3"-6"+ is possible, with locations above 5,000 feet possibly seeing 6"-12" of wet snow.
