On a beautiful and sunny early March afternoon I had been walking through a forested area, when I stopped to look at the surrounding landscape through a gap in the trees. I saw this huge blanket of cloud gradually approaching, cutting the sky in two diagonally, and having my camera with me took the photograph shown above.
I’m not sure about particular weather patterns, whether it was a cold front retreating from a warm one or not, but certainly one type of weather was being replaced by another in a dramatic fashion, and the front line of the new cloud system was incredibly straight.
As the sunshine gradually receded a memory of my schooldays came back to me. Quite frequently I would be in a classroom where looking out the left window I would see rain while there was none to be seen out of the window on the right. Had I been sitting on the front line?
