A new phenomenon

To me at least. 
A weird weather day, the forecast big thunder arriving later in the day. 

S set off for a walk with far too much descent for the knee and I went for an amble. I found myself up above the valley but despite different cloud systems above and below me I stayed dry. And then I looked down at this, which for all the world seems to be a rainbow beneath me, where I suspect the lower cloud was producing rain. Odd. 


Then home to some admin ahead of what will almost certainly be a blip next week.
