The forecast for this weekend's Inaugural Western States Championship at Sonoma Raceway still looks awesome. The only changes were to the temperatures for Friday through Sunday. Looks like highs will stay in the mid 70s, and lows in the mid 40s. There will be a few clouds floating overhead on Wednesday from the 3PM to 9PM timeframe, but no precipitation expected at all.
