There are a few changes in this update to the forecast for the next two days at Sonoma Raceway. Some higher wind speeds are looking likely in the afternoon for both Saturday and Sunday as a result of a stronger pressure gradient at the surface. The slightly cooler temperatures seen for Saturday's high and Sunday's low are likely caused by these stronger winds as the cooler air moves into the region from the Pacific.
