The weather continues to look great for the 25 Hours of Thunderhill. The only weather impact may be some windy conditions on Thursday for the testing sessions. Winds from the north will be sustained at 15 to 25 mph, and may gust to around 30 mph at times. It will still be breezy on Friday, but not as windy, with winds between 10 and 15 mph most of the day. Temperatures for the start of the race will be mild for Northern California this time of year, reaching the mid 60s by the afternoon. On Sunday, an upper level trough will be approaching, and it may bring a few more clouds. But any rain associated with it will not arrive until long after the race is over.
