Thursday will feature the most sunshine of the event weekend, while there will be more clouds than sun from Friday through Sunday. There will be a small chance of rain starting during the afternoon hours on Friday afternoon, then increasing for the evening through the overnight hours.
Saturday morning will start off with a small chance of showers and maybe a thunderstorm, but those chances will decrease some for the afternoon. Sunday will be a dry but mostly cloudy day to start, but will become partly cloudy by the late afternoon.
Early morning lows will be in the 50s throughout the event weekend, with daytime highs topping out in the mid-60s to the lower 70s.
I'll have radar for the event up and running on our site and on the Pirelli World Challenge website (world-challenge.com) by Thursday morning.
