So, if you want to grow up to be a tornado tour group leader, a Jim Leonard hurricane chaser or a tornado chaser you are on your own to study and learn how it's done. If you intend to make it profitable much hard work will be involved. I hope you like physics and math. Currently the government still has a liberal vacation policy for their employees, so chasing on your own time will be possible. Also, summer chase jobs for college students are occasionally available in Oklahoma and Colorado, but they are not offered every year.
TV stations have chaser - on air meteorologist positions.
On air TV is a tough business and not the best job security. Storm chasing and watching the weather is a wonderful hobby. As long as you don't take it seriously or as a full time job you will probably enjoy it. Actually getting in your car and driving after a storm is a big step that most should not take. Just understanding the storms as they come by your house or place of employment can be enjoyable and valuable knowledge.
