Forecasting Models
The next step that forecasters use is to look at computer forecasting models, which show different scenarios of what might happen with the weather. Every day, millions of observations from satellites are recorded into these models, and they are frequently updated to improve future weather forecasting. Meteorologists have dozens of these models to look at, each of which can produce a different result every time atmospheric conditions are altered slightly. This collection of models, called a model ensemble, gives meteorologists an even greater number of possible predictions.
