A weather forecast is a prediction about the atmospheric conditions in a specific area over a certain period, usually a day or a week. It tells us what to expect, such as whether it will be sunny, rainy, or snowy. Meteorologists use various tools and data, like satellite images and weather stations, to make these predictions. Knowing the weather forecast helps people plan their activities. For example, if the forecast predicts rain, you might decide to carry an umbrella or stay indoors. It’s an essential part of daily life, guiding decisions about clothing, travel, and outdoor events.
