| You could see rain/snow falling from the clouds (beautiful dark grey clouds, winter sky) all day as they created a line against clear sunny skies right along the foothills. But none of the rain/snow ever got to the ground. It just created veils that disappeared as they got close. Anyway, colder than I expected with the wind gusts. |
