When water vapor in the atmosphere cools, it becomes tiny droplets of water light enough to float in the form of clouds. As the droplets collect, they become heavier and may fall to the earth as precipitation (rain, snow, hail, sleet, etc).
If the air temperature is cold enough, the droplets will actually freeze before falling all the way to earth, producing snow or hail. The difference in what you get depends on what is happening in the atmosphere where the vapor is freezing. If things are relatively calm, then the vapor turns to thin crystals, floats down, bounces into others, and you have snowflakes.
However, if the atmosphere is turbulent with updrafts, the vapor can be frozen, start to fall, pulled back up, recoated with more vapor, and frozen again. If this occurs repeatedly, when the crystal is too heavy to be pulled back up, it will fall as a hail stone.
Many thunderstorms, hurricanes and tornadoes produce hail stones because of the turbulence they create in the upper atmosphere.

A hail storm has nothing but hail, which hits hard. A snowfall just has nothing but snow.
If you're going out in the snow, be sure to bundle up and hope there's no blizzard forecasted. If you're going out in a hail storm, go find a helmet, put on the darn helmet!

Hailstorm: is basically a thunderstorm with crystals of hailstones fall. It is fatal most of the times. Rain always accompanies hailstorm
Snowfall: is the shower of snow due to reduction of temperature in winters of some subtropical and polar regions. It is not fatal. Rain does not occur.
