Overall, good weather is expected at IMS for the combined INDYCAR and NASCAR events for Brickyard Weekend. The main risk of rain at the track will come on Friday night as an upper level trough swings across the area. The most likely timing of this rain should not affect any on-track action, however a few showers will be possible into Saturday morning. The chance of rain should be gone by the time the INDYCAR race starts at 2 PM. Sunday's weather looks great for the NASCAR race, with mostly sunny skies. Temperatures through the weekend will peak in the mid to upper 80s.
