You could really say we have a "Carbon Copy Forecast" throughout the event week out at Sonoma Raceway for the running of the 2018 SCCA Runoffs. The reason for not much change in the forecast is that a ridge of higher pressure is located to the north of the state in the Pacific Northwest, while a trough of lower pressure is located over the far southern parts of California and into the desert southwest. In weather terms, this is called a "Rex Block" pattern.
With very little movement in the pattern expected throughout the week and weekend, conditions will stay pretty consistent with the only difference being that winds will weaken some after Wednesday. With the weakening of those offshore winds, we may have to include a chance of fog in the forecast during the morning hours later in the week, but it is just too early to know that for certain at this point.
Highs each day will be in the mid to the upper 70s with early morning lows in the 40s. You'll definitely need jackets for the mornings and trade those for shades and sunscreen during the late morning through the afternoon hours. A great week ahead at Sonoma.
