Allright, I've just completed the developing and texturing phase of my map, and so now only the further detailing phase remains. For those who want to see what I did for the last four hours in texturing phase, here are some pics.

I fixed those two nodraw errors after noticing in this image.

Getting back to the point, I'd like the atmosphere to be during a dark and stormy night, and to pull that off I'd need actual rain. So how do I do this?

Use a particle effect. There is even an option to mark it as weather.

That brings me on to the next topic, how the hell do you open the particle viewer? I saw on a youtube video there is such thing as a particle viewer, but I see no option anywhere to open it.
Also, do I just need one particle in the middle or a bunch?

It is part of the in game tools, launch the game with the "-tools" argument to access those.

Depends on which particle you use. I would recommend Psy's weather effects with collision as they can detect rooftops and such and not pass through them. Then you simply create a info_particle_system and add the rain particle effect name in the name box. According to Psy: "For Sawmill there are 2 rain effects; env_rain_001_collision (1024 units) and env_rain_002_collision (256 units)."

The particle viewer in hammer only exists in newer versions (portal 2+), TF2's hammer sadly is an older version and doesn't have it. You have to browse them with -tools on TF2 itself as henke said.
