Syntax of weather will the future weather use the simple present tense or the future tense?

The prospect of tomorrow is sunny. It is expected to be sunny tomorrow.

The simple present tense is used in this sentence, but sometimes there will be future tense, such as this sentence, it will be sunny tomorrow, no problem at all.

Therefore, to analyze the specific context, I tend to use the simple present tense in most cases.
