You don't have to be a psychic or a scientist to predict the weather.
Just look up and see how the clouds are forming. Clouds observation
can be your guide to weather forecasting.
Fair weather
Cirrocumulus clouds are white clouds at high altitude, from 1,500
feet to 45,00 feet. Though they are made of ice crystals, they
signal fair weather. Those high, thin, and wispy clouds are known as
cirrus clouds. They often indicate fair weather the same with those
fluffy cotton clouds known as cumulus clouds.
Rain and snow
Cirrostratus clouds are thin clouds that cover the sky. With these
clouds, there's a hint of the sun or moon, that are sometimes blocked
by other types of clouds. Thicker cirrostratus clouds can lead to
rain or snow. Unlike the cirrostratus clouds, stratocumulus clouds
don't cover the sky fully. The low, lumpy, gray clouds are seen in
patches or lined in rows. They can produce rain, but not at all
times. Nimbostratus clouds, on the other hand, are dark gray in
color and may indicate rain.
Storms
Altocumulus clouds are known as middle layer clouds that can lead to
thunderstorms when they form. If you see gray clouds with a hint of
blue, what you're seeing are the altostratus clouds that can help
predict storms. Meanwhile, stratus clouds are low layered. They can
lead to drizzles. Cumulonimbus clouds, however, can lead to
thunderstorms, hail, and possible tornadoes. These clouds come with
a flat base and an anvil top.
