You are not in the mood for grey weather anymore? You are fed up with snow, sleet and roads slippery with black ice? You still have some leftover leave from last year? Lucky you! You could take the next flight to someplace nice and warm. Where the sea sparkles in the sunlight in shades of blue, where you walk barefoot in the warm sand and enjoy colourful sunsets and mild evenings at the hotel bar. At least, that is how it should be. If luck turns bad on you, the winter weather might be following you and your spontaneous trip might be drowned in thunderstorms and rain. That would be a shame, but still not a matter of life and death. Of course.
„At a red moon and a bright star, thunder and lightning are not far“ or „When the sky is sailed by sheep of white, the weather will stay nice and bright”. These and other weather proverbs and sayings have a tradition of many centuries. They are based on experience and weather observation but nowadays, as we are able to make very detailed predictions on our weather regarding time and geography, they seem slightly out-dated.
