Consider the following sentence with a first conditional:
If it rains tomorrow, I will go to the cinema.
All the examples of first conditionals that I found use "will" instead of "would." Is it possible to replace "will" with "would" while retaining the same exact meaning, i.e.,
If it rains tomorrow, I would go to the cinema.
Or, would I have to put the inflected verb in preterite form (as mentioned in this related posting), like this:
If it rained tomorrow, I would go to the cinema.
[Edit 1: I clarified that I want to retain the same meaning among these examples.]
[Edit 2: Corrected silly mistake where the first example was the same as the second example.]
