Having a cavalier attitude isn't part of my job description. The convective picture was a concern. A thunderstorm system is a dynamic event. When questioning our dispatchers regarding the wisdom of routing that aimed directly at the weather, the actual flight proved their planning to be appropriate. On the majority of occasions, the storm moves away. It's a strategy used by water-skiers. What do I mean exactly? If a water-skier is towed near the shoreline on one side of a flat, calm lake, the tactic is to return back to the same side for the reverse run after a minute or two. The reasoning is that the wake will travel to the opposite side of the lake, dissipating from the original side first. In that regard, a line of thunderstorms will move its wake away from the flight route by the time the airplane arrives. If the water-skiing strategy proves wrong, it is rare that a break in a line of thunderstorms can't be found. A modest deviation would be all that is required. In our circumstance, extra fuel had been added for just such a contingency.
