NASCAR has a 3:30 PM start time as the latest time they would start the race. Track driers are out I hope this race gets in. Monday and Tuesday do not look good weather wise at all.
This Speed TV article says that if the race is fully rained out this week that it would wind up as the last race in the chase this year.
2PM Update: Does not look good at all at the racetrack rain wise and it takes around 2 hours to dry the track.
