Switchable weather on multiplayer maps?

[AradorasXeon]

Is there a way to switch on/off fx_rain or snow in multiplayer? I thought it would be just a simple targeting issue, but if I go to the trigger the snow and rain just gets thicker, Also it start to rain and snow from the beggining.

MP doesn't support this out-of-the-box unfortunately, and no amount of entity hacking in maps will get it working. You'll need a server-side mod such as Makermod which implements this using its /mweather command. Makermod doesn't offer an entity for controlling weather though, but perhaps another mod such as Lugormod does.
