I still think that the race on Saturday is most likely to stay dry. However, I did add a slight chance of showers in the afternoon. The reason for this is that the sea breeze is expected to move inland during the day, and depending on where it ends up, it could spark a few showers in the vicinity of the track. Forecasting a small scale feature like the sea breeze this far out is difficult, but it is at least a possibility that it will reach Sebring in the afternoon. If it does occur, any rain should be light and not cause major problems.

On a side note, Scott and I will have some exciting news coming soon about a new venture for Racecast Weather!
