It actually depends on where in the world your continent is situated to depend on where the rain comes from. (However, in the United States, your NW to SE is very accurate.)

What is important is that you choose a direction for your wind and rain to travel in, and notice that rain will dump on the first mountain range it reaches, leaving a rain shadow behind it.

desert vs grassland and Forest vs jungle will depend on a lot of things, so you can play around with a lot of things as long as you get the general patterns right.
