Overcast

Overcast is a weather condition characterized by a uniform gray sky where clouds cover the entire sky, blocking direct sunlight. It typically indicates thick cloud cover associated with overlying weather systems like rain or snow. Overcast skies can lead to cooler temperatures and reduced visibility but generally do not produce severe weather by themselves. This state results from extensive cloud layers, often in the form of stratus clouds, creating an even, diffuse light environment. Overcast conditions are common in various climates and are an important factor in weather forecasting and planning outdoor activities.
