Rhymes With Pie

The Mono Monday challenge this week, set by Laurie54 , many thanks for hosting.
My first thought was sky ,but when I looked out it was raining heavily and the sky was a uniform grey.  not at all interesting.  However, by lunch time it was a completely different picture with blue skies and fluffy white clouds.  So even taken with the black and white setting on my camera the sky had more shapes and contrasts.  It is back to grey and raining again now.  I have added the blue version as an extra to remind myself we did have nice weather for an hour or two.
