Big Sky

(Back-blip)
On the way to Beddgelert from Capel Curig, (near the Pen-Y-Pass trurn off),
I saw a huge black cloud developing behind Snowdon with Blue skies above, it looked dramatic.
By the time I had pulled over and got my camera out, the Snowden Horseshoe had dissapeared in a new low grey cloud that had moved in from right to left.
For a while it was fascinating to watch two cloud levels moving in different directions.
This lower cloud settled and filled the valleys and hung around till the next day. This gave me the temperature inversion I experienced in the next blip.
