Just a random idea, what about making rain random prop (well, not some huge cars, something like melons ?) all over the map.
Usage :
[command] -> prop spawn on the sky by X number each Y seconds for Z time -> fall on the map (can dammage player, cvar ?) -> destroy all prop after X seconds.

This is just a random idea, so if someone : have time/think it's funny/wanna make me happy/have drink too much coffee and MUST script something/???/all of those option at once and he is going to do it, well, thanks.

Lots of physics props can lag pretty bad, esp if they use collision

Sounds like a fun idea though

maybe this is a good start

There would need to be away to determine where the skybox is. I think this is only determined by texture on the brush? Might be some way to find what texture the brush is using and loop through all brushes to find the skyboxes then pick random points at random intervals below these skyboxes and spawn a prop.

traceray upwards to the sky and get the endpoint... you have to get the mask right though.

then only spawn 'rain' within a radius of any player, that way sometimes it may be outside the map but there'll always be some near people

Trace ray might hit ceiling instead of sky.

Why shouldn't it hit the ceiling?

Rain doesn't go through the ceiling in most cases. Unless you meant using the filter for checking if the brush is indeed the skybox. Ceiling of a map != skybox always.

Traceray wont return if it is skybox.
