The weather is not an easy thing to forecast.
All day and night, weathermen are collecting information from ships, planes, weather stations, and space stations.
With the help of this information, they can understand what the weather will be like during the next few days.
Although no two days will have exactly the same weather, some types of weather people can forecast.
