2013 NASCAR at Auto Club Speedway race day weather forecast: Lots of sunshine

Sunny skies and warm temperatures for the 2013 NASCAR Sprint Cup race at Auto Club Speedway

When you think of the perfect NASCAR weekend you think of weather like this, lots of sunshine and warm pleasant sunshine. One year ago, rain shortened this race but not this year. Mostly sunny skies for Auto Club Speedway in Fontana, California. Temperatures to start the race will be in the mid to upper 60s, but warming into the low to mid 70s by the afternoon. Skies will be mostly sunny, so instead of rain gear fans are going to need sun block.
