Here are the average temp in Yosemite Valley (where CV is located) by month: www.nps.gov/yose/planyourvisit/climate.htm. Also beginning of September is usually still quite warm. Nights can have a bit of a chill, but nothing a couple of blankets can't handle.
September's weather is a lot like July and August, only a bit cooler. Temperatures typically range between 55 degrees and 70 degrees and average precipitation during the month is 3.7 inches. It gets a little cooler later in the month, so bring along a light jacket.
