^Name looking for a tutorial on creating weather effects (snow, rain, etc.) I did a search but couldn't find one. Anyone got a link or some pointers.

To make weather you need to find the .weather_particle_system tag which can be extracted from the campaign maps.

For rain I modified the c10 one to remove the insects. Snow you can get from c40 I believe.
They should be in tags\levels\levelname\

Then edit as you wish.
Now, in sapien, go to cluster properties -> palettes -> weather palette

Then click "New Instance" at the top.
select your new instance and reference the particle system. Set scale function to 1
Then reference the wind. (If you don't the flags wont wave in the wind)
A decent .wind tag can be found in tags\levels\b30\outside.wind

Set the direction to X: 1 Y: 1 Z: 1 the magnitude to 1 as well as the scale function.
Then Ctrl + S to save it. Make sure you save it immediately afterwards, because you are modifying the BSP not the .scenario, if you click on something like "vehicles" it will save the scenario, but if you have anything under "cluster properties" selected it will save the bsp.

aren't there some weather tags in kornmans environment tags DL?

Where exactly can I find wind tags to reference I'm searching my folders and I'm not seeing any.

You can extract them from the campaign maps. I don't think they are installed with the HEK. I just use levels\b30\outside.wind in all of my levels.

there is one wind installed with HEK under levels\test\tutorial\multiplayer.wind.

You can use that tag and rename and play around with the settings to get different effects or rip the campaign like elefant said.

Set it up like you said and I got no snow falling :( , I'm not sure if I did something wrong but when I originally tried to reopen in Sapien it crashed Sapien. I may have set something up wrong?

Cant you just modify the wind magnitude and direction in the scenario tag?
