Later in the day, the Coca Cola 600 will be held at the Charlotte Motor Speedway. There is a chance for a thunderstorm during that race too, but again it will be very much a hit-or-miss sort of thing.
Individual thunderstorms have well defined edges, and so do the rain patterns they produce. Why, just the other day my son (works at a local golf course) reported heavy rain on 17th fairway and 18th tee, but not a drop of rain fell at the clubhouse (less than 500 yards away).
