Flurries are a light snow which falls for a short time. Snow which falls at different rates for short periods of time is known as showers. Different rates means different speeds. Thus, snow may fall quickly and heavily for a time and fall slowly for a time. Some snow may accumulate on the ground.
Squalls are snowstorms which have heavy snow showers and only last for a short time.
They also have strong, gusty winds. A good deal of snow may accumulate on the ground. Squalls are most often seen near the Great Lakes Region. Blowing snow makes it hard to see, and it can pile up into drifts. This can happen when the snow is falling, or by the wind picking up snow which is already on the ground.
