Testing this afternoon at Thunderhill is going to be wet, as rain will be spreading across northern California from the late morning through tonight. Expect rain to start at the track between 11 am and 1 pm. It could come down fairly heavy at times this afternoon. It will be breezy, with south winds of 10 to 20 mph, and gusts up to 30 mph possible. The rain will continue through tonight and early Friday morning. Most of the rain should be gone by sunrise, so I expect that Friday's testing will be rain-free, although the track may be wet in the morning. The total amount of rainfall at the track from today through Friday morning will likely be around a half inch.
Saturday's weather looks great, with plenty of sunshine. It will be chilly in the morning, with lows in the upper 30s, but highs will reach the upper 50s by the mid afternoon.
Sunday continues to have a lot of question marks. There is a good chance of seeing some rain during the day, but the big question is when. The race will end at noon, and it will be close as to whether the rain arrives before the end of the race. I have a 50% chance of rain mentioned through the day, I think that the morning will have lower rain chances than that, but I can't rule it out entirely. While I said in earlier forecasts that all 25 hours would likely stay dry, I'm not as confident about that happening today. There is still no clear consensus among the models about the rain, so stay tuned for updates as we get closer to Sunday.

I plan on having another update Saturday morning, unless there is a major change before then.
