Saturday is looking dry, but with a few more clouds than today. Highs will reach near 80 again, with winds around 10 mph. There could be a few isolated showers around central Florida, but I don't think they will impact the track while racing is going on.
Sunday continues to have a chance of showers and thunderstorms, but I still think the chances of rain during the racing are low. There are some other forecasts that I've seen that have higher rain chances, but I'm not convinced that rain is a sure thing. There is still some disagreement in the models with how much moisture there will be, and the trend of all the models recently has been toward less moisture and less rain. I'm keeping a 30% chance of rain on Sunday, but that also means that there is a 70% chance that the day will stay dry. So don't let that small chance of rain keep you away from the track if you're thinking about going to the race.
