Tornado warnings have become a regular event each spring and even into the summer in Middle Tennessee. This month, we sit down with Jason Wright, senior meteorologist with the National Weather Service, for an in-depth discussion on severe weather. Questions about how weather patterns are observed, interpreted and predicted are sure to come up, as well as how technology for tracking weather has improved. We may even touch on how weather patterns have changed over the years and what all those severe weather warnings really mean. This brings our three-month series on Forces of Nature to a close.
