I went up to Dickson, TN to meet up with some other friends that are into tornado sirens and weather (my main hobbies). While we were there, at around midnight, a Severe Thunderstorm Warning was issued for our location. Of course, with all of us being into weather, we ran outside to record the constant CG lightning. We noted slight rotation about 2 miles north of us. None of us were even thinking about CMAS, but there were no alerts ever sent out for the Severe Thunderstorm Warnings. We went inside, and we saw a Flash Flood Warning pop up in the NWS Chat (by far the quickest way to get warnings). Within about 5-10 seconds, we hear the
EAS attention signal playing in the pattern of 3 on, 1 off, repeating for about 5 times. We were all confused...we thought it was some kind of EAS alert playing from a hidden radio or something. One of our friends from Central Georgia was there, and he pulled out his phone (Verizon Android) to reveal the message "CMAS ALERT - Flash Flood Warning for this location until 4:15 AM CT". Again, no Severe Thunderstorm Warning CMAS, only Flash Flood Warning. o_O I don't know what was stranger: the tone they picked, or the lack of warning for the Severe Thunderstorm Warning. I do have to say that I was VERY impressed with the quickness of the warning being sent out. It is rumored that the iPhone will allow CMAS messages for iOS 6.
Sorry for the long message, I got carried away a little bit
