Most common cause would be the plus wires. Dampness causes them to arc and the cylinder that the wire is arcing on won't fire causing a miss/sputter.
A car could sputter in the rain if the car needs new seals. There could also be a spark plug or wire that needs to be replaced.
A vehicle may sputter after a heavy rain due to rain water getting into the gas tank. This can be fixed simply by purchasing a fuel injector cleaner from a local automotive store.
