What is the best way to predict the weather?
Meteorologists also use satellites to observe cloud patterns around the world, and radar is used to measure precipitation. All of this data is then plugged into super computers, which use numerical forecast equations to create forecast models of the atmosphere.
How do weather forecasters predict the weather?
Predicting the weather is a process involving many different methods that meteorologists , also known as forecasters, and scientists who study weather, use, including: forecasting tools – satellite, radar, and surface maps (which show high and low-pressure areas).

Either it rained when it wasn’t supposed to, or the amount of rain/snow was different than predicted.

What causes the weather?
Weather occurs primarily due to air pressure, temperature and moisture differences between one place to another. These differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics.
