DISCUSSION: In light of the moderate risk issued for much of Oklahoma and northern Texas for the afternoon and evening hours today, the WeatherTAP Facebook team was inspired to post a series of graphics which help to explain how supercell thunderstorms work in typical large-scale convective situations. Attached below is a compiled explanation of how supercell thunderstorms are typically approached by storm chasers and what reasons that approach is taken.
"With a moderate risk for severe storms in western Oklahoma today, you're likely to see some radar images of some supercells. Supercells are uniquely structured and quite complex. I found three images that I hope will help you understand the complex structure of supercells. Often, the best place to be as a chaser is just to the south of the hook. Before we can even get supercells we need four things to happen: wind shear, instability, moisture, and lift."
