Green flag takes place at 2:35 pm EST and there will be no weather worries for the first half of the race. Skies will be mostly sunny with temperatures in the lower 60s at the start, but clouds will slowly be on the increase and those temperatures will eventually begin to drop into the lower 50s by 7:00 PM and will be close to 50 degrees by midnight with mostly cloudy skies.
The system may be close enough to the track that a stray shower or two could pass over, but those chance remain very small through the rest of the pre-dawn hours. Those shower chances will be on the increase as we pass sunrise, unfortunately becoming likely by 8:00 am and through the rest of the race. At this point, the rainfall doesn't look all that heavy with amounts possibly topping out around 1/4 inch by the checkered flag.
Sunday's temperatures will start off around 50 degrees at midnight and only drop into the upper 40s by 8:00 am, then quickly rising to around 60 degrees by 1:00 pm. It should be close to 60 degrees at the checkered flag with rain likely.
The good news is that there should not be any lightning in the area throughout the race and rainfall shouldn't be heavy enough to cause any stoppages, but may be enough for a caution flag or two. Winds throughout the race will start off out of the northeast at 6-12 MPH from start through midnight, then picking up 8-16 MPH out of the north after midnight with gusts up to 20 MPH possible near the finish.
