I'm stuck. How do I create a stormy scene, at night? Anything I come up with looks to dry, and doesn't look realistic/right. Help?

Wet surfaces are reflective using an anistropic Fresnel reflectance. But might not be uniformly wet, so best approach would probably to use a mapped metal or mapped phong shader with variable reflectance.

Just an educated guess, though. I don't think I've actually done a "wet" scene before...

An overcast HDRI or background image might help too.

Im agree with Jack, and another tip can be using few lights and on materials use high shinny values..that helps to get a wet look.. I think Use Mapped Shader for this case is the best option to make some parts wet and others not..

I think you need to work with the lights and materials for a while to find the best settings..

HTH. (TOMG trademark) :D

I've seen people use bump maps to simulate rain running down surfaces like windows but ive never tried it

Have you tried the ripple rain plugin? it simulates rain; but not sure if it actually gives you good water droplets sticking to surfaces.
