Hey guys. I want to go racing this weekend, but the problem is, the closest track is 7 hours away. I really want to make sure I hit the best air possible. The only two viable options right now are Friday evening from 7 to 11pm, or Sunday from 11am to 4pm (they are calling for rain all day Saturday). I know Barometric pressure plays a big role in DA. Since they are calling for rain Saturday, I'm assuming the Barometric pressure will be decreasing Friday evening, therefore, rising the DA. Sunday is the opposite, with the forecast calling for nicer weather until Wednesday, but with warmer temperatures and sunny. I'm not sure when to go, and I really want to make it count because it is the last test and tune session of the year. I included the link to the local weather so you can check out the forecast. Any input would be greatly appreciated!
