Weather conditions for Sonoma Raceway are mostly consistent in this forecast update with the initial forecast from Monday. Friday morning, the upper level trough mentioned in the previous forecast will still be centered over the region with winds at these levels from the direct west. Moisture will be brought in to the region from the Pacific, resulting in partly to mostly cloudy conditions in the upper levels during the morning. Conditions are expected to clear during the afternoon as upper level winds shift to the northwest.
Warmer temperatures are likely for Saturday as surface and low levels winds will be from the north to northeast, transporting warmer air to the region as they move over the land. Much like in the previous forecast, upper level winds will be from the southwest on Sunday and will cause some cloudier conditions over the track. Recent model runs show increased moisture being moved into area, which will increase cloud cover as a result.
