the forecast is a prediction 24-48 hours in advance. In most locations, this
prediction is only 70% accurate and it is a good idea to consult the
National Weather Service for more accurate weather forecasts. In some
locations, this prediction may be less or more accurate. However, it is still
an interesting educational tool for learning why the weather changes.
The National Weather Service (and other weather services such as
Accuweather and The Weather Channel) have many tools at their disposal
to predict weather conditions, including weather radar, weather models,
and detailed mapping of ground conditions.
