Widely scattered afternoon thunderstorms are typically associated with an unstable air mass, often containing maritime tropical air with thunderstorms driven by thermals in an unstable atmospheric environment.

Cold fronts and warm fronts can also generate thunderstorms, but "widely scattered" suggests that the storms are not associated with a large-scale weather system like a midlatitude cyclone.
