I was first introduced to the term ‘DEF CON’ (defense condition) by the movie War Games. On a scale of 1 to 5, DEF CON 1 is the most severe…the most dangerous. DEF CON is not a term used in weather forecasting, but meteorologists at the Storm Prediction Center in Norman, Oklahoma have released their latest outlook for severe weather today and tonight, and it is the most severe, the most dangerous on their scale of 1 to 5.
