It can snow or rain for days but, in my experience, hail showers rarely last very long.

those balls of ice come down at a pretty good rate of speed. golf ball sized hail can easily break car windows. anything bigger than that, u could wind up gettin severely hurt.
the biggest stones come from supercell's. those dont just drop hail, they can spawn tornadoes. the hail is dependant on a strong updraft. the stone gets blown back up in the freezing layer until the flow cant hold it. the bigger the hail, the stronger the updraft....and that also means the storm itself is extremely strong.
hail has also been known to kill. a golf balled sized stone could be at 70 mph by the time it hits the ground.

Hail falls from severe thunderstorms. Typically severe thunderstorms are moving relatively fast (20-40mph) because of the fast winds aloft, and are small (as apposed to broad scale rain or snow). Therefore when hail falls it does not last long because the storm producing it passes by pretty quickly.

hail is not temp related like snow. Hail is caused by thunder clouds. water is pushed up through the clouds spinning and bouncing around it freezes, and when it get heave enough it will fall to ground but these things only happen for short periods of time.

The formation of hail in the cloud is such that the updraught keeps them 'up there'. They collide and get bigger inside the cloud and when they become so heavy that the updraught can't hold them - they fall.
