What can I see at night to know whether it will rain or sunny tomorrow?

Seeing the stars, the next day is likely to be sunny.

Look at the red clouds It rained the next day.

Look at the moon. It may be sunny or cloudy.

Seeing walking in the moon cloud may be cloudy or cloudy, and it may be cloudy or sunny when it is windy.

Look at 19: 30, weather forecast. All the above are known. Ha.
