As you probably heard on the news, Flagstaff got pounded by a blizzard the past week. We received about 4 feet in Kachina Village. It's always challenging making good snow pictures - the camera's meter wants to make the white snow 18% grey, falling and blowing snow soak your gear, fingers go numb, and then when you bring the cold camera back into a warm house, moisture condenses on it. (Put your cold camera and lenses in a plastic bag outside before bringing them inside.)
Once you check your histogram and maybe "add more light" using the exposure compensation button to get the snow bright and white, then you may want to play with white balance. For example, setting the WB on tungsten will give your image a bluish cast making the scene look extra cold. Experiment and stay warm.
