Snow is frozen raindrops.

Nimbostratus clouds...
Cirrus clouds are high enough to be at a low enough temperature for the water droplets to form into ice crystals. However, Cirrus clouds are not precipitation clouds, so no snow or rain can fall from them. The clouds that can cause snow to fall in the right conditions are Nimbostratus and Cumulonimbus clouds.
Those are likely nimbostratus clouds. They are thick, dark clouds that form a continuous layer and often bring steady precipitation, such as rain or snow, over a large area.
Temperatures must be at or below 32°F (0°C) for snow to form and fall from the sky. Snow forms when water vapor in the clouds freezes into ice crystals and then combines to form snowflakes.
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.

Feet. Low clouds form at an altitude of 2000 feet.
Yes, clouds are necessary for snow to form. Snow forms when water vapor in the clouds condenses into ice crystals and falls to the ground. Without clouds, there would be no source of moisture for snow to develop.

nimbostratus
Snow crystals form when water vapor condenses directly into ice. This happens in the clouds.
