Soonerdave... Also, Slight, moderate, and high refers to all types of Severe weather. I understand in a way the torcon does also, but for the most part torcon gives the casual observer the chances of a tornado happening within a 50 mile radius of whatever destination they choose (e.g. Eastern OK/Central OK). It helps people understand in a way what the chances of tornadoes are. Some people get confused with slight, moderate, and high cause that could mean different things. It's kind of like people not knowing the difference between watches and warnings if that makes since to you. I never said it was a perfect system though sir
