What will the weather be like tomorrow? I am surprised by this sentence in the book. What's the weather like now?

How's the weather? What is the weather like now? )

What will the weather be like tomorrow? What will the weather be like tomorrow? )

This sentence uses the simple future tense. The future tense consists of will and verb prototype, for example:

We will take the exam tomorrow.

He will come this afternoon.

It will be fine tomorrow.

In interrogative sentences, the future tense usually puts will before the subject, and other verbs are still behind the subject. The above example becomes a general question:

Do you have an exam tomorrow?

Will he come this afternoon?

Will the weather be fine tomorrow?

Your question "Can you change the ordinary future tense to what will the weather be like tomorrow?" "

The answer is no, because will can only be placed in front of the subject the weather, and the prototype of the be verb should still be placed behind the subject the weather. You think these sentences are a little strange. As long as you accumulate more correct English sentences, you will be familiar with them.
