In real life, a snowstorm has depth. It engulfs things. We can simulate this by adding several layers, increasing or decreasing the scale of each to make it look closer or farther away. I used five layers of snow. You can have more or less, but five was fine for this image. There may be (probably is) a better/quicker/easier way to do this, but I'm going to stick with what worked for me:

1. Duplicate the Snow Layer Set. The default name of Snow Copy is fine for our use. Activate the new layer set.
   
2. Open the set, ungroup the Curves Adjustment Layer from the layer of "snow", and select the layer of "snow".
   
3. Edit -> Transform -> Scale and set the scale to 50% using the boxes at the top of the screen. Make sure you click on the little link icon between the width and height boxes.
   
   
   
   
4. Align the shrunken layer with top-left of the image:
   a) Select -> All
   b) Layer -> Align to Selection -> Top Edges
   c) Layer -> Align to Selection -> Left Edges
   
   
   
   
5. Duplicate the shrunken layer and use Layer -> Align to Selection -> Right Edges to align it with the right side of the image.
   
   
   
   
6. Merge the two shrunken snow layers: Layer -> Merge Down
   
7. Duplicate the merged layer and align it with the bottom of the screen: Layer -> Align to Selection -> Bottom Edges
   
   
   
   
8. Layer -> Merge Down. Group the Curves adjustment layer with this newly filled layer to complete the filling.
   
   
   
   
9. Next Look for vertical and horizontal lines caused by replication. Use a large soft eraser brush with an opacity of 50% or so to clean it up.
   
   
   
   You should now have something similar to this:
   
   
   
   Repeat this set of steps using this newly created layer set as the basis. Itll add another level of depth in the distance. You can do this as many times as you want, but a total of twice should be sufficient, producing something like this:
