There is always a chance of rain interrupting things at any outdoor event, but as the previous post shows, this site is ready to take on the weather with minimal impact.
The rain on Sunday totaled 1.1" at the site, and was welcomed by the organizers as conditions were very dry and the risk of field fires was high. The grounds are already back in good condition, and ready to go.
The forecast does hold some possibility for rain, but also of moderating temperatures with highs in the mid-70's predicted for Saturday.
