How can I create a Thunderstorm ?

I was wondering if anyone knows of any tutorials or could advise me as to how I can go about creating a Thunderstorm?

I don’t need the rain part, I just want more like a Lightning & Thunder kinda Storm where it’s dark and eerie looking.

I’ve kinda figured out how to take the skybox + volumetric fog to create a dark and eerie look.

I also found a tutorial I like for lightning but, I wanna create a blueprint script or something that would cause a thunderstorm to occur in the map once someone’s character walks through a trigger box for a haunted house map.

Any ideas or advice would greatly be appreciated, thanks so much!

if your in a house all you really need to do is to make a light flash and have a sound play. put that on a random play interval and you got what you need. its seems pretty simple you would make the light flash by setting its intensity.

Thank you for the suggestion. I may use that for another project but, for this I need to figure out something similar to an actual thunderstorm and just leave out the rain, more like a before it gets ready to rain with lighting and thunder because in my project map the player can go inside and also outside the house. I was looking around a tutorials but haven’t found anything yet so I am not sure currently how to do it.
