Weather forecasting isn’t one-size-fits-all. Different weather models analyze the atmosphere in unique ways, leading to variations in predictions. Now, with RainViewer’s latest feature, you can switch between multiple forecast models to get a more complete picture of what’s coming your way. The update is available in versions 6.6 (iOS) and 6.9 (Android). What Are Weather Models? Weather models are advanced computer simulations that predict atmospheric changes based on current conditions. They process massive amounts of data, including temperature, wind, pressure, and humidity, to generate forecasts for different regions and timeframes.
