Hello! Jim

I would like to consult you some confusing questions. They are not confusing but could be. I thought I could handle most of the subjunctive moods after reading lots of rules. But I still find some examples hard to understand once in a while. I think I understand it but I am not sure about my interpretation. I need your help.

If the weather is good, I'll go hiking.
--> This is the most popular pattern that occurs in the grammar books in the market. It points out that there's a possibility that the weather is going to be nice. So using "will" works well if I mean to say I'll go hiking definitely;the possibility of going hiking is almost 100 per cent sure.
If the weather is good, I might go hiking.
-->With "might" used here, I am not so sure of the possibility of going hiking. I might go hiking or I might go jogging. It depends on my mood.
If the weather is good, I would go hiking.
--> I don't know if this one is 100 percent correct. I'd like to add one more word, "If the weather is good, I would probably go hiking." How do you like it? I mean to point out the possibility of going hiking as well as the possibility in my previous example.
Are these three sentences all right for you?
Regards,
Pastel
