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

Nascar_2013_fontana_forecast_medium

Unlike last year where rain shortened the NASCAR Sprint Cup race at Auto Club Speedway, California will live up to its nick name of “Sunny California.” The sunny weather of Friday will continue through the rest of the weekend. While there may be areas of patchy fog in the morning, there will be lots of sunshine during the afternoon. Afternoon temperatures will also be very pleasant reaching the low to mid 70s. After the challenging forecast last weekend at Bristol Motor Speedway, this meteorologist is going to enjoy watching the NASCAR race and not looking at the radar.
