A Clear Line

When you live in a narrow valley with 8000+ mountains all around, you get used to not having much warning of weather changes - at least not the visual clues of distant lines of clouds coming.  This morning after the morning fog cleared out, there was a few hours of blue sky and then before you knew it the light changed and I looked up and a front of clouds was rapidly closing in and 'putting the lid back on' the valley for another few days of forecast rain and snow.
