Saturday looks mostly sunny and warm - a great day for racing and a nice evening for fireworks.
A cold front will be approaching from the northwest late Saturday night and Sunday, and bring a chance of showers and thunderstorms. There are some timing differences in the models with this system. I have a 20% chance of rain mentioned Saturday night only because of the timing uncertainty, but it appears that the majority of showers and thunderstorms will be on Sunday. This far out in the forecast, I don't feel confident enough to pin the timing down any more precisely than that.
