Quote of the Day “Life changes like the weather. You just have to predict and adapt.”
Weather Witchcraft- Many, many years ago, predicting the weather was considered witchcraft…what do YOU think? Proverb is a short pithy saying in general use, stating a general truth or piece of advice People have been forecasting the weather for centuries. They once looked to plants and animals for hints about what the weather would do.
Weather Proverbs When looking at weather proverbs, keep this in mind: They are usually based on someone’s observations and not on scientific studies. Because climates and weather patterns differ throughout the world, a weather proverb based on observations in one location may not be valid in another location. Some proverbs arose simply from coincidence, not weather patterns, and therefore may seldom hold true. But under certain circumstances, some proverbs do hold up to science. Here are some that, under the right circumstances, have proven valid.
