From there, it only gets more dicey.
The chance of rain increases to 55 percent by 1 p.m., 70 percent by 2 p.m. and 80 percent by 4 p.m., which is only 30 minutes prior to the scheduled beginning of Monster Energy NASCAR Cup Series qualifying (live on FS1).
The chance of rain, according to weather.com, remains at between 50 percent and 65 percent for the remainder of the day which will likely make it difficult to dry the track even if the rain halts from time to time.
