The StrikeFinder can also help identify serious convective activity, but
then again, so can NEXRAD + Echo Tops.

... except Nexrad is at least seven minutes old, and sometimes fifteen.
What prompted the question was watching hearing boomers out my window,
and seeing that Nexrad had only light rain showing. On the next update,
seven minutes later, some moderate rain was showing. Meanwhile, it was
thunder and lightning outside my window.


NEXRAD can be a couple minutes old, or up to several minutes old
(assuming you receive the 5 minute updates.) It isn't "at least seven
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.
