I have created a pretty good looking snow effect (that DOESN'T lag) and I will release it for modders to enjoy. Just pack into your mod (or map) and place on the map in patches of 1 per 500 meters. Do NOT attempt to place more then one in any 500 meter area or risk a CTD. The game CTDs if there is more then 5000 sprites on the screen. (it won't crash if there was 5000+ particles though, but it would lag to hell.
)
So this is the most snow you can get, but it's better then nothing and still looks great!

(free imaginary cookie if you can guess the map I'm testing this in!
