Cool air rising through warm air (apex)
A cold front advancing
A thunderstorm typically requires moisture in the atmosphere, atmospheric instability, and a lifting mechanism. However, a lack of warm, moist air would not be conducive to thunderstorm formation. Therefore, dry air or stable atmospheric conditions would not be part of the recipe for a thunderstorm.
Ingredients that are not part of the recipe for a thunderstorm include flour, sugar, and eggs. Instead, a thunderstorm forms due to the combination of moist air, instability in the atmosphere, and a lifting mechanism such as a front or a mountain range.
