The leaves here have been so slowly turning color that it's almost as if it wasn't happening. While the saplings and short young trees have been exploding in red, orange and yellow, the large trees haven't been in a hurry.
Today, driving home, however, I noticed that the larger trees seemed to be converting to fall color rapidly. Part of this may have been from the temps in the 30s we had a few nights ago, but I think it was more because it was overcast, the sky a high, light grey. I have noticed this even in New England with the trees at their "glowingest" of scarlet, melon, and goldI remember the Columbus Day weekend we went to Lake George, and it rained and rained, but nevertheless the trees seemed to be alight from within. One maple tree at a rest area had the most breathtaking crimson leaves I had ever seen. They never seem so bright on sunny days.
Perhaps it's because the trees have to compete with the too-brilliant sunlight and the bright blue of a fall sky, for certainly the trees didn't appear yesterday as colorful as they did today with a monochrome backdrop. Each maple in the neighborhood had at least one side that was bright with red or yellow shading into orange.
