Wishes about the future

wish / if only + would

This pattern is used for wishes about the future when there is a chance that something may happen or somebody (but not the person who wishes) may change their behaviour:

I wish it would stop snowing.
I wish Mark would call me back.
I wish more people would read my blog.

Wish + would can also express not-so-polite requests or complaints:

I wish you wouldn't smoke in here.
