You somehow don't expect there to be sky in Leeds. There is so much going on above eye level that the sky seems just an insignificant covering over the top. So when it is actually interesting, it makes the view over stimulating.

Today the slice of sky filling the void between the towering Yorkshire Bank and the wide Norwich Union was a detailed mesh of overlaping greys. Each fractal edged cloud was of a contrasting grey to the next, the lighter ones evenly dispersed among the darker to make a checker board over the sky. it was like an intricate line drawing or a precise Escher print - not like weather at all.

In the next slice it was entirely different - a patch of pure blue framed by sharp edged white sheep clouds, their outlines brightly illuminated by the hidden sun. One stray grey wisp spoiled the summery view - its indistinct boundaries messing with the cut glass scene.
