Here is the current radar. Everything seems to be moving directly west-to-east. The speedway is located roughly under the center of the letter "n" in "Daytona".
There seems to be a dry-ish patch over Ocala right now. That will take about 2 hours to reach the speedway. Track drying could begin then. After that point, we just have to hope that the batch in the Gulf just north of Homosassa Springs (that's a city, not a slur) tracks slightly to the north. If so, we could get a little lucky and get this in tonight.
I remember the 97 Indy 500.
Day 1 was a washout.
Day 2 ran 15 laps and then done for the day because of more rain.
Day 3 (Tuesday) you could pretty much sit in any seat you wanted, the crowd was about 40% of normal.
Well... this radar update looks a lot more promising... appears that a bunch of the rain has dissipated. Hopefully the dryers are already running!
