What is Weather?       


What is the weather like today? Is it cloudy, windy, warm, or wet? Weather is what we see when we look out the window. It describes outside conditions at a particular time for a specific area. Weather forecasts predict sun, heat waves, storms, tornadoes, rain, sleet, hail, and snow that may occur on a certain day or during a week. When we understand weather, we can prepare for it and change our plans accordingly.
