Dramatic sky

On my way home this evening, after experiencing a series of light snow storms high in the Chiltern hills, I saw this dramatic sky-scape over the Vale of Aylesbury. Another snow or hail storm was funneling down somewhere in the Vale as the sun set. I pulled up where a gap in the hedge gave a view over Tring Reservoirs just before the light rapidly diminished and this wonderful cloud scene faded to grey.
