What are unbroken layers of low gray clouds bring light rain snow or drizzle?

Unbroken layers of low gray clouds that bring light rain, snow, or drizzle are typically associated with stratus clouds. These clouds form in stable atmospheric conditions and cover the sky like a blanket, leading to overcast weather. When the moisture in these clouds condenses, it results in light precipitation, such as drizzle or light snow, often lacking the intensity of heavier rain systems.
