Which one can I use?

Hi guys, Can I borrow your knowledge in English?

I was playing catch with my friend and I was about to throw the ball to my friend.

I said something like "Here it comes" to my friend right before throwing the ball.

Then it occurred to me that there might be other expressions that I could use.

Possible expressions I come up with are:

1. Here it goes.

2. Here goes.

3. Here we go. (slightly different in meaning, but it's possible, isn't it?)

Am I right? Is ther any other similar expressions I can use in this situation.

Any replies are appreciated.

Thanks you,
