Twilight clouds
Friday evening, about half an hour before sunset, the low sun hit evening clouds that were blowing up against the Swan Range to my East.
Thunderstorms were pushing the clouds against the ridge.
I was taking these photos as thunder rumbled – barely heard – to the West-Southwest. What a contrast – blue sky deepening to dark with sunlit clouds spread by the wind of the approaching front: twilight clouds.
