What was the weather like when the fish scale cloud appeared?

It's sunny, rainy, rainy, etc. Cirrostratus of ichthyosis, also known as cumulus, usually indicates the change of weather, which generally appears between summer and autumn. The clouds are thin and scattered, like fish scales. If there are fish scale clouds, it means that a fast-moving weather system is coming, such as cold air, low-pressure system or rainy days. Therefore, fish scale clouds can usually predict changes such as sunny days, rainy days and temperature drops. Fish scale clouds are caused by upward movement and water vapor condensation, and usually appear in the upper atmosphere. At the same time, cumulus clouds are formed at the intersection of cold and warm air, so there are often signals of weather changes.
