Tennessee weather is as unpredictable as it is powerful, and few people understand its nuances better than retired meteorologist Davis Nolan. He joins host Chip Walters on the sixth anniversary of the devastating Cookeville and Nashville tornado outbreak, we look back at the meteorological anomalies that defied standard expectations. Nolan breaks down the "gasoline and engine" theory of storm development—explaining how a night with low instability and mid-50s dew points managed to produce an EF-4 monster that changed Middle Tennessee forever.
Beyond the history, this conversation serves as a masterclass in modern storm tracking technology. From the "debris signatures" on correlation coefficient radar to the specific apps the pros use when the sirens go off, you will learn exactly how to interpret the red and green velocity maps on your phone. Whether you are prepping for the upcoming spring season or curious about how La Niña transitions affect tornado frequency, this episode provides the data-driven insights you need to stay weather-aware.
