Data from NOAA, via Paul Douglas' On Weather blog.

  1. I was just wondering aloud last night - do the tornado counts include the all the times where "the radar shows a possible tornado", or just the visually confirmed ones? Because, based on the weather reporting around here, there are LOTS of possible rotation images in the radar that never actually become a tornado.
