-- Changed Discussion --
Isentropic lift is producing areas of light rain across the southern half of the Tennessee Valley into southwest North Carolina. The light precipitation will continue to spread northeast overnight. Looking at the forecast soundings across the higher terrain...and current conditions at NewFound Gap of 37 degrees and dewpoint of 23...expect a mixture of snow/sleet across the higher elevations. This mixture generally at or above 4000 feet. Places like the Smoky Mountains...Roane Mountain...and High Knob could see a coating of light snow. Since rain is spreading northeast a little faster than expected...have up the time of getting light precipitation this evening. Made some minor changes to going forecast lows for tonight. Will continue wind advisory for the Smoky Mountains for Sunday.
