A rain shower is a brief period of rainfall, often localized and intermittent. It's typically shorter and less intense than a rainstorm. Rain showers can start and stop quickly, often with periods of sunshine in between. They are common during unstable weather conditions and can occur at any time of day. The intensity of a rain shower can range from a light sprinkle to a moderate downpour. Think of a rain shower as a quick splash of water from the sky, followed by a return to normal weather.
