For those who are curious, some enterprising Modder made a snow mod. It doesn't actually cause snow like a weather expansion would, but it can give the appearance of it. However, considering modders work alone, or in small times, I have to give kudos to this modder, especially with Christmas around the block.
Be aware the main site is in French:

Here is an item on this mod:
I did not give a release date for now
This mod is intended primarily for people who play in neighborhoods like Newcrest and Willow Creek because Oasis Spring is a rather warmer world. But instead it will be a little changed also because the developers have used the same objects to the world.
Hello everyone I invite you to discover very soon a winter mod I would suggest for download on the site! Know that I have nothing at all to change the operation of the game. All the trees have been recolored, I also played with the layers (alpha) to give the trees as branches! This makes for some days that I am about this project, I have shared many pictures on twitter. But that changed a little between yesterday and today! I'm still working on it, but I'm looking forward to release it! In all cases a very big thank you to Zerbu for his help!
Here is an item on this mod:* All items could not be recolored (it's not for lack of trying)
* It works like the autumn mod, it replaces the textures of trees and objects (in the neighborhood)
* It will not snow in your game (am not competent enough to create such big things! Haha)
* I made the snow mod for the basic game for now. I'll see later if I would do for Granite Falls Magnolia Promenade.
* To play with the mod simply removing it from the mods folder, period!
* I did not manage to alter routes for their particular texture of snow! If someone already found I am interested!
