Question

Quizplus · Accepted Answer

Thunderstorms require a combination of moisture, instability, and a lifting mechanism. Solar heating during the day causes the air near the surface to warm, creating unstable conditions. As the warmer air rises and cools, it forms cumulus clouds which can grow into thunderstorms under the right conditions. Therefore, afternoon and early evening are the most likely times for the development of thunderstorms due to the increased instability.
