Fair to partly sunny skies and your July 4th forecast with only isolated thunderstorms around East Tennessee. Hot and humid with heat index readings well above 90° and near 100 in parts of East Tennessee. That kind of heat can be dangerous so be sure and stay hydrated. Thunderstorm chances increase to 40% Thursday and 60% Friday. I will be on 105.7 Wednesday afternoon and will let you know if any thunderstorms show up on radar
