2015 NASCAR All-Star Race and Nationwide at Iowa Speedway weather forecasts

The weather forecast for Saturday night’s Sprint All-Star race at Charlotte Motor Speedway and the Xfinity series at Iowa Speedway aren’t all bad. Only one track has a chance of rain this weekend.

The weather forecast for Saturday night’s Sprint All-Star race at Charlotte Motor Speedway looks warm and dy. We will have partly cloudy skies and temperatures will be in the 70s during most of the race. Weather will not be a concern tonight in Charlotte.
