Fog Sandwich

Its been a fog sandwich of a day. Way into work on the train the tops of tallest buildings were obscured by the low hanging cloud and the air had that moist grey feeling of fog (even though the visibility wasn't bad). Middle of the day the sun managed to brighten up the sky, warmth came through. Seemed very much an end of summer day, rather than the autumnal we have started to become accustomed to. By home time the cloud has come down again and in the distance the tall buildings have disappeared once again into the sky.
