@Tiv-3film Thanks for chiming in and trying to help. I'm a professional meteorologist so I can help clarify. A weather radar is a giant piece of actual equipment (giant pertaining to the WSR-88Ds that make up the land-based US network) that show current and past distribution of atmospheric "stuff" - it can see water vapor, rain, snow, bugs, dirt, debris, etc etc.
A weather model, like the ECMWF "Euro" or GFS or NAM, are merely algorithms (equations) or AI-based machine learning software that run on supercomputers that predict the future. So "future radar" is really just a weather model showing what the radar could look like in the future. Not anything you could use an actual radar to compute. Hope that helps and happy weathering!
