For all three days at Road Atlanta, expect sunny and clear conditions throughout with a few stray clouds floating around. No threat of showers or thunderstorms. Highs will top out in the middle 80s, with overnight lows in the lower to mid 60s.
If i have to change anything to this forecast, it will be that I'll have to add an increase in cloud cover starting late Saturday afternoon. This is due to the low pressure system may start to move west and on shore. I still do not believe that there would be any rainfall until Sunday. Even then, the chance is very small.
