NASCAR Phoenix International Raceway Race Day Weather Forecast: Scattered Shower Or Two

Scattered showers remain in the forecast for Phoenix International Raceway on Sunday. Storm system is expected to move through northwest Mexico on Sunday. Most of the showers will be south of the Phoenix area along the Arizona, Mexico border. There will be a few scattered rain showers during Sunday morning but I expect most of the afternoon to be dry as the morning activity moves east and south of the race track. Worst case scenario for Sunday afternoon is if a isolated shower moves over the track causing a yellow-flag caution or maybe a brief red flag. Skies will be cloudy, and temperatures will be cooler as highs only reach the upper 60s to near 70.

SUNDAY:
3 p.m ET
Sprint Cup Race – Mostly cloudy, cooler, possible shower – temp: 66
