Turn the calendar back 5,000 years and think about it: those who planted rice and barley knew the right time to plant, knew when the rivers would flood their banks, and could tell pretty well what the weather would be like on the next day.
Many of us are surrounded by concrete; we're not looking up at the sky, we're looking at our IPhone. We listen to the weather forecasters on TV and complain about how often they are wrong. But we can regain the lost art of forecasting the weather if we want to, with no gadgets to assist. Amaze your family and friends! Marisys has a lovely page on how to forecast the weather. Give it a try.
