This is a quick showcase of a few of the ways to create snow in 3Ds Max.
Snow, normal noise with some FFD transformations. This is to bring the snow up in specific areas (where the wind blows).
The bricks, I used a rather cool trick of inverting a displacement map and simple adding a white texture to it. This gives the effect of snow being in-between them. This scene only really took about 10 minutes to make, yet looks pretty cool!
