What time does the weather forecast mean during the day?

"Today's daytime" means 12h from 8 am to 20 pm.

======================================

Radio and TV stations have weather forecast programs every day. Here is a little common sense: "Today's day" means12h; 8 am to 20 pm; "Tonight" means 12h from 20:00 to 8:00 the next morning. "Cloudy" means that the amount of clouds accounts for 40% ~ 70%; "Yin" means that the cloud cover accounts for 80%,100%; "Clear" means that the cloud cover accounts for 10% ~ 30%.

The forecast time shall not exceed 12h, and refer to the precipitation level standard of 12h. For example, it is predicted that there will be thunderstorms at noon or at night today, which means the precipitation within 12h. If it is predicted that there will be moderate to heavy rain from day to night today, it refers to the precipitation within 24 hours.
