     On My Future Radar you can see the future, or at least what the weather forecast models think the future will be. Data is displayed using Rapid Refresh and NAM forecast models to provide simulated future radar imagery. 
     Rapid Refresh is the continental-scale National Oceanic and Atmospheric Administration (NOAA) hourly-updated assimilation/modeling system. The Rapid Refresh model is run hourly and is useful for short term forecasting. 
     The North American Mesoscale forecast system (NAM) models provide simulated future radar imagery and is one of the major weather models run by the National Centers for Environmental Prediction (NCEP) for producing weather forecasts. NAM uses dozens of weather parameters from temperature and precipitation to lightning and turbulent kinetic energy to generate multiple grids of weather forecasts over the North American continent and forecasts are generated using additional numerical weather models. NAM is run 4 times a day and typically has data from the present to 2.5 days in the future.
