The forecast throughout the weekend can't really be any better for racing. Cooler temperatures will make it better for the drivers, but those same temperatures will warrant the need for jackets at multiple times throughout the event. The only concern that we may have is smoke from the nearby fires.
Friday will be a rather cool and quite breezy day, with winds starting out of the northeast and shifting out of the northwest at 5-15 MPH with gusts up to 20 MPH likely. According to how strong the system that will be moving into Nevada, we may have to increase those winds speeds.
Ridging will start to build in for Saturday and Sunday, bringing warmer daytime highs and lighter winds. Conditions will remain really dry throughout the weekend, and those jackets will be needed for the mornings. Highs on Saturday will be in the lower 70s, with upper 70s expected for Sunday.
Radar will be up and running starting on Friday morning, but it will not be needed.
