Snow flurries are minor snowfalls that cause light dusting or no snow accumulation.
During snow showers, the intensity of a snowfall varies and lasts for brief periods. Some amount of snow may accumulate.
Snow squalls lead to, typically, a significant accumulation of snow.
Blowing snow causes serious drifting and visibility reductions.
Blizzards are the most dangerous. They are strong snowstorms characterized by strong winds and poor visibility, lasting for an extended period, usually three to four hours. Blizzards can be enormous and usually extend for hundreds or thousands of kilometers.
