Severe Thunderstorm Ingredients. The development of a thunderstorm is dependent upon three primary ingredients: atmospheric instability, moisture and a lifting mechanism. Severe thunderstorms, and supercell thunderstorms in particular, also require vertical wind shear.
A thunderstorm will form first and develop toward the region that has the best combination of: high PBL moisture, low convective inhibition, CAPE and lifting mechanisms. The difference between a thunderstorm and a severe thunderstorm is the wind field. For a severe thunderstorm, the ingredients that must be present are moisture, instability, lift and strong speed and directional storm relative wind shear. Ideally, wind will have a veering directional change of 60 degrees or more from the surface to 700 millibars, upper level winds will be greater than 70 knots, and the 850 to 700 mb winds (low level jet) will be 25 knots or greater.
