Every day, we can see a weather forecast. The forecast tells us what the weather will be like. We can find the forecast on TV, on the radio, and on the internet. The forecast uses information from different places. Scientists called meteorologists study the weather. They look at temperature, wind, and rain. They use computers to make predictions. The forecast helps us plan our day. If the forecast says it will rain, we can take an umbrella. If it says it will be hot, we can wear light clothes. Sometimes, the forecast is not correct. The weather can change quickly. But the forecast is usually helpful. It helps us to be ready for different kinds of weather.
