Why is the temperature in the morning weather forecast from high to low?

The forecast during the day is from high to low, because the coldest time of the day has passed. People who forecast the next day at night will report from low to high, and the coldest time will appear around midnight.

If it is a noon forecast, it will report the situation from afternoon to evening, so it will report the high temperature in the afternoon first, and then the low temperature in the evening, which is actually the temperature the next morning. If it is night, it will report the temperature from night to the next day. Usually within 24 hours. For example, after CCTV news broadcast, the weather is reported from 8: 00 that night to 8: 00 the next night.
