ever daydream while looking at a cloud here are some facts

clouds are found in three types high middle and low.
three high clouds are cirrocumulus, cirrostratus, and cirrus.
three middle clouds are altocumulus, altostratus, and lenticular.
three low clouds are stratocumulus, nimbostratus, and stratus.

The cloud that looks best to me is the cumulonimbus clouds because it takes up most of the sky and blocks out the sun...

these clouds bring hail, rain, sleet, snow, along with cold weather.
