Skywatch - Mackerel sky

The striking chimney of Saltaire's New Mill (see also yesterday's photo) and one of the old lamp-posts (once gas, now electric) outlined against a 'mackerel sky'.  These clouds, properly termed altocumulus or cirrocumulus, are known as a mackerel sky as they resemble the scales of the fish. There is much folklore attached to them, rooted in fact, as they often herald a bout of wet weather on the way in 6 or 8 hours.  I have a particular fondness for them.  My old geography teacher - an inspirational man - once enthusiastically dragged me outside on the way out of the school morning assembly to show me just such a sky and teach me about it.  I've never forgotten that special little lesson.

"Mackerel sky - never long wet, never long dry."
