Hey, just thought I'd throw out the suggestion of adding a weather effect layer. (. . .)
As Jonathan the Black has said above, this has been discussed previously.
For instance, you can check these threads:

It occurs to me that an overlay layer would be good for more than just map items. (. . .)
I agree. It would add more versatility to the use of images in the Roll20 page canvases, for map purposes or for handling background and descriptive images with more options.
It is possible now to create these effects using existing resources, through, element manipulation, like resizing, applying auras, and using sound FX.
Of course you can place an Aura for a token and tell to your players: "this represents smoke".
But for instance, if you place a smoke image intended as an overlay into a map, you'd need to place tokens over the smoke (spoiling the overlay effect . . .) or you will be unable to select them --you will select the smoke image/token/overlay instead.
This was raised in the Environmental Effects (Smoke) Suggestion thread by @John_Marshall (I'm quoting from there):
it dawned on me that this will get complicated when it comes time to use this set up. Selecting and moving tokens will inevitably end up dragging smoke around. Ideally the 'smoke' layer would sit on top of the other layers and not be selected. Tokens would move around 'under' the smoke. I was thinking of how to overcome this when a simple answer occurred to me.
Diverse ways of locking tokens (making them unable to be selected/moved) or using an extra layer for handling this have been discussed in the aforementioned threads.
But one thing lacking is some artistic person to create some good smoke, mist, and fog tokens. I have only found one green smoke token, which works alright for, well, green smoke or mist. Would be nice of someone could recolor it to white, gray, red, etc.
I can make color variations of already existing smoke tokens easily. Perhaps you can send that green smoke token to me, then.
Although creating new tokens would require more time and I'm lacking of it at the moment.
