What's the best station around ATL to watch for severe coverage? I've got 11 on right now.

 

Please take jokes to the banter thread.

 

But if you want to see Glenn Burns show case his exclusive broadcast right to show GRLevelX images over the air in Atlanta (or at least I thought that was true at one point)...tune in to him.

 

I'm born and raise and the ATL area and have since realized how bad our TV weather stations are.
