Ask The Weatherman for July 29, 2013:
Question: When looking at radar, what do you look for in identifying a tornado?
Answer: The best way to identify a possible tornado is to look for a hook shape echo in the storm pattern. This will be one indicator of a tornado. Secondly you can use the velocity option and look for the dark colors and the light colors coming together on the velocity chart.
