I was looking around the Google Play Store and found Zello. Zello is a PTT app that turns your phone in to a Handi-Talkie. You can use it to talk 1-1 with another person, or connect to a Zello channel and talk/listen with a group. I went through the list and there are several weather related channels, or you can start your own, even a WxForum channel.
I haven't tried it yet, but am planning on a 1-1 test with a friend.
