This thread scares me just a bit. I hope everyone understands that NEXRAD weather and ads-b are planning and big picture aids. They should not be used to avoid convective activity while flying in actual IFR conditions. The NTSB has attributed quite a few fatal accidents to pilots who attempted this. The time delay is simply to long. Here is a link to a article on the subject.

Maybe I'm missing it, but I don't see anyone talking about skirting wx in this thread. Just discussing ADS-B performance
