Beautiful imagery of snow in Sansa and Theon's chapters:
Yet she stepped out all the same. Her boots tore ankle-deep holes into the smooth white surface of the snow, yet made no sound. Sansa drifted past frosted shrubs and thin dark trees, and wondered if she were still dreaming. Drifting snowflakes brushed her face as light as lover's kisses, and melted on her cheeks. At the center of the garden, beside the statue of the weeping woman that lay broken and half-buried on the ground, she turned her face up to the sky and closed her eyes. She could feel the snow on her lashes, taste it on her lips. It was the taste of Winterfell. The taste of innocence. The taste of dreams. (Sansa VII, ASoS)
--
Outside the snow was coming down so heavily that Theon could not see more than three feet ahead of him. He found himself alone in a white wilderness, walls of snow looming up to either side of him chest high. When he raised his head, the snowflakes brushed his cheeks like cold soft kisses. He could hear the sound of music from the hall behind him. A soft song now, and sad. For a moment he felt almost at peace. (A Ghost in Winterfell, ADwD)
