In today's highly developed science and technology, how to look at the weather from the clouds?

Knowing the weather from the clouds can predict the short-term (no more than 24 hours) weather changes, which is scientific in itself.

People who live in a certain place for a long time and observe the weather changes for a long time (such as farmers, fishermen and hunters) can predict the climate for a long time if they combine the climate changes at that time, the past years and the local meteorological changes.

There is no contradiction between empirical prediction and scientific attitude. Science itself relies on repeated experiments to find laws.
