Editor's note: NBC broadcasters will offer opinions on upcoming races the remainder of the season. This week, analyst Steve Letarte discusses Saturday's Bank of America 500 at Charlotte Motor Speedway, starting about 7 p.m. on NBCSN.
As drivers return to Charlotte Motor Speedway for the second time this season, talk centers on two things: Martin Truex Jr.'s dominating run last time the series was at the track, and the potential for rain over the weekend as Hurricane Matthew heads toward the U.S.
This weekend starts the second round of the Chase for the Sprint Cup.
