In this image the snow is very visible, snowing sideways into the picture. On a windy day it can be tempting to stand with your back against the wind, but the snow is more visible if you turn 90 degrees and stand with your shoulder against the wind. Try out slow(er) shutter speeds. The slower the shutter speed, the longer "stripes" of snow. You need to use a lenshood, and bring a micro fibre cloth to clean your lens continuously.
