Future with will,going to and may / might
will/won't + infinitive is used to talk about a future prediction based on a personal viewpoint:

Adverbs of possibility
definitely,almost certainly,probably and possibly are often used when making predictions.See how they are used in a sentence:

The first conditional
We use the first conditional to talk about real possibilities in the present and future:

You'll have to pay more if you want an eco- friendly car.
There are two clauses. The if clause, is the possible condition and the second is the result of that condition:
We do not use future forms in the if/condition clause:
If global warming continues the sea level will rise
For results that are not certain, we can use may/might instead of will:
If you don't put out your cigarette properly, you might start a forest fire.
