What weather does the burning cloud portend?

There is a proverb that goes like this: "Don't go out at sunrise, but it will take thousands of miles at sunset." It means that if there are fiery red clouds in the morning, it may rain; If it is night, it will be sunny tomorrow.

There is also a proverb: "Burn it in the morning and water it at night." It means there will be flaming clouds in the morning, but it may rain at night. This is similar to the first half of the previous proverb.
