Our streak of dry Sunday race days for the Monster Energy Cup series continues in Southern California at Auto Club Speedway. It will be another race day with plenty of sunshine, but unlike Phoenix last weekend, temperatures should be comfortable, ranging from 65 to around 70 degrees. Winds won’t be an issue either, as they will be out of the southwest between five to 10 mph.
