OK, maybe I am dense but I have never seen a radar map for the weather that is going to happen. Just like radar tracking an airplane can't show where the plane is going, only where it is or has been. We can't actually see into the future.
We can look at the last 6 hours of radar and predict/estimate based on that-which is what every radar map, in every weather map shows. The funny part was that she wanted future radar and there is no such thing unless we bend space/time. But I guess it's not funny if it has to be explained. *shrug*
