Forecast for the Go Pro Grand Prix at Sonoma

8/25/2015

Comments

 
By Doug Schneider
It is difficult to think about the next IndyCar race today after the horrible news of last night. With heavy hearts and prayers for the Wilson family, the series moves on to Sonoma.

The weather pattern for the second half of this week along the Pacific coastline will feature a high pressure ridge over the desert southwest and Rocky Mountains, with a low pressure trough moving east across the eastern Pacific Ocean. Temperatures will be warm Thursday and Friday ahead of the approaching trough, then cool down a little beginning Saturday as the trough moves through. Any rain associated with the trough is expected to stay well north of the Bay area at this time, and it should only bring some more clouds to Sonoma on Friday and Saturday. Mostly sunny skies return for Sunday, with temperatures remaining pleasantly comfortable in the upper 70s. Nice weather continues into Monday for the IndyCar championship celebrations.
