OK, thanks so much, kekert. I actually looked at the hidden layers to see if it might be there, but didn't see it. I missed it in it's current location because it doesn't have a header like Radar & Satellite and I'm used to that one being at the top. It's really a terrific feature.
And for what it's worth, the Rain Accumulation layer is dynamite for anticipating a system's next move. Way better than trump with a Sharpie.
Thanks again for the help.
