Large balls of ice can fall from the sky

Ice is not normally associated with San Diego, but on the morning of February 27, 2018, areas including Carlsbad, Escondido, Ramona and El Cajon experienced a passing hailstorm. Hail starts as rain droplets that freeze at high altitudes. With the right conditions, these frozen rain droplets combine with other droplets and grow larger until the hail gets heavy enough to drop from the storm cloud.

How does hail stay suspended in the air? Is hail always the same size? Why or why not?
