Mid-altitude clouds, usually between 7,000 and 20,000 feet. They create a uniform white to grayish sheet covering the sky, often preceding steady rain or snow.

High-altitude clouds, typically above 20,000 feet. Thin and wispy, they indicate fair weather but can signal approaching fronts or storms when they thicken.

Low-altitude clouds, typically below 2,000 feet. Layered and uniform, these clouds often cover the sky like a blanket, leading to overcast conditions and drizzle.

High-altitude clouds, normally above 20,000 feet. Small, white patches, often arranged in rows, these clouds are rare and do not usually produce precipitation, indicating fair but cold weather.
