Today will be the warmest day of the race weekend at Sonoma Raceway as team load into the track. Highs are expected to reach into the upper 80s under sunny skies.
A few more clouds will be around the area on Friday as an upper level low pressure trough and surface cold front approach from the west. The rainfall associated with this system is expected to stay north of the track. although I can't entirely rule out some light sprinkles Friday night. If there is any rain, I don't think it will even be enough to measure (less than a hundredth of an inch), so I'm not including a chance of measurable rain in my forecast graphic. Saturday is expected to have mostly cloudy skies as the cold front and upper trough pass through, and temperatures will be cooler, with highs in the upper 70s.
Dry weather and pleasant temperatures will continue for Sunday and the IndyCar championship festivities on Monday, with highs both days in the upper 70s.
