Tail of the Dragon, Cherohala Skyway, and Moonshiner 28 summer weather: It is typical throughout the summer months for the weather reports in the mountains of western North Carolina to call for 60% chance of thunderstorms. What this really means is there will POSSIBLY be an afternoon shower. These scattered cells are small and short lived. They occur in the period of 2 pm to 4 pm and then the sun returns quickly drying the roads. There is no need to cancel your trip here because the weather says 60% chance of thunderstorms. Many days we don’t even see any rain when its predicted.
