Hail is produced exclusively within tall, towering cumulonimbus thunderclouds driven by strong atmospheric instability and severe updrafts of warm, moist air. When violent upward wind currents carry raindrops high into the freezing sub-zero upper regions of a thunderstorm cloud, the water droplets freeze instantly into ice pellets. As these pellets cycle up and down multiple times inside the turbulent cloud, they accumulate successive layers of moisture and ice, growing steadily heavier until the updraft can no longer support their massive weight, causing them to plummet violently to the ground.
