an ice storm has as much to do with hail as a rain cloud does to a dust cloud. hail is produced when rain droplets typically during the spring and summer months, are drawn up into large thunderstorms by the updrafts. the updrafts lift the rain to such a height that it then turns to ice. the stronger the storm, the more this process is repeated and larger the stone will become.
In 1979 in fort collins, colorado, the only fatality occurred when a stone the size of a grapefruit hit an infant as her mother rushed into a nearby mall for cover. an ice storm is rain that turns to ice on contact with the ground. as described herein, a hail storm drops hail which is already in the form of ice which hits the ground as ice, not freezing rain, which occurs during the cold months of the year, opposite of when hail storms occur.
