cumulonimbus clouds block out sunlight!
Nimbostratus clouds are thick enough to blot out sunlight. This type of cloud is associated with heavy, continuous rain or snow.
The clouds you are describing sound like nimbostratus clouds. These clouds are characterized by their thick, low-level appearance and can bring continuous light rain or drizzle as they cover the sky, blocking out sunlight. Nimbostratus clouds are often associated with overcast and gloomy weather conditions.
Clouds can turn black when they are full of moisture and become thick and dense. This can happen before a heavy rainstorm or thunderstorm, as the clouds block more of the sunlight and give the appearance of being black. Additionally, pollution or smoke in the atmosphere can also make clouds appear darker.

During the day, thick clouds can block sunlight and reduce the amount of solar radiation reaching the Earth's surface, which can lead to cooler temperatures. At night, thick clouds can act as a blanket, trapping heat that would otherwise radiate away into space, resulting in warmer nighttime temperatures.

It would block out significant sunlight, lowering the temperature.

Clouds that typically block the sun include thick, dense clouds such as nimbostratus and cumulonimbus. Nimbostratus clouds are low, gray clouds that cover the sky and bring continuous precipitation, while cumulonimbus clouds are towering and often associated with thunderstorms. Other cloud types like stratus and altostratus can also obscure sunlight, depending on their thickness and coverage.
Thick clouds can block sunlight during the day, reducing the amount of direct sunlight that reaches the Earth's surface and keeping it cooler. At night, clouds serve as a blanket, trapping heat that would otherwise escape back into the atmosphere, leading to warmer temperatures. This process is known as the greenhouse effect.
Storm clouds appear dark because they are thick with water droplets and ice crystals that block out sunlight. This causes less light to pass through the cloud, making it appear dark from below.
The grey smooth clouds that cover the whole sky and block out the sun are called nimbostratus clouds. These clouds typically bring overcast skies and steady precipitation. They are thick and uniform, often appearing as a continuous layer, which prevents sunlight from penetrating through. Nimbostratus clouds are associated with gloomy weather conditions.
Low, shapeless rain clouds are often dark gray in color, indicating that they are dense and likely to produce precipitation. These clouds, typically known as nimbostratus, lack the defined structure of other cloud types but are thick enough to block sunlight. Their dark appearance is a result of the moisture content within the clouds, which can lead to steady, continuous rain.
Thick clouds can have a moderating effect on temperature in surrounding areas by trapping heat during the night, which can prevent temperatures from dropping as low as they might under clear skies. During the day, however, these clouds can block sunlight, leading to cooler temperatures. Overall, the presence of thick clouds tends to create a more stable temperature range, reducing extremes between day and night.
Clouds appear dark when they are thick and dense because they block out sunlight. This can happen when there is a lot of moisture in the air or when the cloud is very high in the atmosphere. The darkness of a cloud can also be influenced by the time of day and the angle of the sun.
The shadow above the clouds is caused by the phenomenon known as a "cloud shadow." When sunlight hits the tops of clouds, it casts a shadow on the layer of clouds below. If the clouds are thick enough, the sunlight may scatter, creating a shadow that appears to rise above the cloud layer. This effect can be enhanced by the angle of the sun and the specific atmospheric conditions.
Overcast days appear gray because thick clouds block much of the sunlight from reaching the ground, creating diffuse and dim lighting conditions. The cloud cover scatters the light in all directions, reducing the intensity of sunlight and giving the sky a gray appearance.
