Cold sky

It was 16° F when we went out in the field this afternoon with a cold north wind. We have not been a proper walk but Pete has plenty of room to nose about at home.

The sky was grey but there were clouds and I did see what I think is Kelvin-Helmholtz formation, the rope-like cloud at the bottom of the sky. It isn't the besr example and if anyone has another suggestion, please let me know.
