Spring & Summer Severe/Hazardous Weather Terms. The air condenses as it cools forming water droplets. As the temperature drops below the freezing point, the droplets become cool and freeze on contact with condensation nuclei. [1] It is distinct from ice pellets (American English "sleet"), though the two are often confused. For large hail, you need a strong updraft, or an upward column of air, to keep hail lofted into the colder parts of the clouds. Ice pellets generally fall in cold weather, while hail growth is greatly inhibited during cold surface temperatures. Hail forms when strong currents of rising air known as updrafts carry droplets of water high enough that they freeze. This is why it can still hail in the summertime - the air at ground level may be warm but it can still be cold enough higher up in the sky. Cold air moves down towards the ground, freezing raindrops into ice balls. They all work about the same way, though: The sun heats up water vapor until it rises, cools and condenses into huge cumulonimbus clouds, which gradually collapse on themselves, leading to rain,.
