@sdetweil I think I actually managed to implement it—so now snow falls whenever “Current conditions” report any of the various “snow” messages.

I renamed the module and uploaded it as a standalone: “MMM-DynamicSnow”

It should work with all weather providers. I created a separate dictionary for it, but so far, I’ve only had time to test it with Swedish SMHI. Also not easy to test during this mild winter, but I did finally manage to find a place where it snowed up north here in Sweden.
