Why does google's weather forecast in Melbourne differ from the Bureau of Meteorology?

Different sites have different predicitons for each forecast. For the most part, they're usually almost the same. I would go with the Bureau of Meterology for Melbourne's forecast.|||Google's weather forecast is usually based strictly on the data the models spit out. So, basically a computer program looks at what the "computers" are saying and just reformats the info into a template.





The Bureau of MET actually takes the time to look at a number of factors. They look at models, local effects, typical model error, among other things. They base their forecasts on not just the models but on their own personal forecasting skills and knowledge.





As a result, the Bureau will be more accurate in the long run.|||There are countless models that a forecaster can use to predict weather. A forecaster uses the model he or she thinks is representative of current conditions and best describes what is going on at the surface and upper atmosphere.
