As the sun rises over Daytona Sunday morning, there could be a few more spits of rain, but they are unlikely to have any impact on the racing. In the afternoon, there is a better chance of getting more rain, however I still expect that before the race ends, the amount of rain will be less than a tenth of an inch. It may require a change to wet tires in the closing stages of the race, or perhaps create some difficult strategy calls for teams deciding if they need to make the change to wet tires. The overall impact of any rain on the race will be low, as I don't expect it to be heavy enough to warrant any delays or interruptions.
The timing of heavier showers today looks a little slower than the past few days, which is good news. I think that any chance of thunderstorms or heavier rain will hold off until after 4 pm. From 4 pm to sunset, around a quarter to a half inch of rain may be possible. But I'm feeling pretty confident that the heavier showers and storms will hold off until after the race has ended.
