Hail is formed through a sort of roller coaster ride through intense thunderstorms. Strong convection currents lift small ice pellets high into the middle and upper portions of a cumulonimbus cloud. This is where super-cooled water droplets collide and the ice pellet grows through a process called accretion. Once the pellet is too heavy for the updrafts to keep it within the cumulonimbus, it begins to fall, and if it does not melt completely before reaching ground level, it comes out as hail. Hail can be classified into three stages of development, grauple, small hail, and hail stones.[Citation Needed]
