NEXRAD can be a couple minutes old, or up to several minutes old

minutes old." However, you have no idea HOW old it is, so I certainly
wouldn't use it to navigate around thunderstorms unless I was VMC.

In that case, why have it at all. In VMC, one doesn't need radar to
avoid the stuff.


Because you have no idea what's up ahead, and whether or not you need to
divert now, or will be able to complete your flight.
