Not all clouds produce thunderstorms. There are two different types of clouds: 1) cumulus and 2) stratus. Thunderstorms are most likely to be found in cumulus clouds but not all cumulus clouds produce thunderstorms. A thunderstorm is a product of convection cells that surge to great altitudes, transporting heat within the atmosphere. Convective storms occur when warm air rises and is replaced with cooler air. This sometimes results in air moving in a vertical circular motion. As a result, towering cumulus clouds will most likely result in a thunderstorm.
