Sunday's ABC Supply 500 has been postponed due to persistent rainfall and thunderstorms. The weather radar indicates that rain may not dissipate until after 6:00 p.m. local time. With sunset coming at 7:51 p.m., there was no chance of drying the track in time to begin racing.
However, the Monday forecast looks much better, with sunny conditions and an ambient temperature above 70 degrees. The race is slated to begin at 12:00 ET on NBCSN.
