Is it possible to 'slant' a noise function?

[pokoy]

I'm trying to get clouds to look slightly slanted so you can tell they travel with the wind direction. Right now I'm using a mask for the noise function which I scale in Y-direction and then rotate so it looks like it's slanted slightly but it's sometimes too obvious and needs a lot of babysitting to look OK. And of course, stretching a noise can easily look fake.

Is there a way to slant the noise without any tricks like scaling?

Here's an example of what I want to achieve:

Use a Twist and Shear shader as the warper for a Warp Input Shader or Warp Merge Shader.

Thanks Matt! I tried this actually but didn't see any effect and assumed it was only meant to work with terrains. Seems I gave up to fast
