I don't know if oldradioguy2010 is still following this thread, but any time I see someone with questions about storm chasing, it sends a chill up my spine. I have lost count of the number of storm spotter classes I have taken and have even attended storm spotting seminars held at the University of Oklahoma and the one thing they all have in common is that they emphasize that under no circumstances whatsoever do they even remotely suggest that anyone "chase" storms.
For anyone who thinks it would be "cool" to chase storms, I have two words for you; Tim Samaras.
Although he did not have a college degree in meteorology, he was one of the foremost experts in the world in the study of tornadoes and convective storms. He, along with professional meteorologist Carl Young and his son Paul were killed on May 31, 2013 while chasing storms near El Reno, Oklahoma.
My point is that there are very few people who have an understanding of the nature of tornadoes and Tim was one of them. Now he's dead.
Do you still want to chase storms?
