Origin and History of the Term Snow Squall
The word squall has been used in English since the 17th century to describe sudden, violent bursts of wind or storms.

Today, national weather agencies around the world use the term in official forecasts and winter weather warnings.
What Causes a Snow Squall?
Snow squalls usually form when:
- Cold air moves over warmer air.
- A strong cold front passes through.
- Atmospheric instability develops.
- Moisture combines with freezing temperatures.
These conditions allow narrow bands of heavy snow to form quickly and move rapidly across an area.
How Long Does a Snow Squall Last?
Most snow squalls last:
- 15 to 60 minutes
- Sometimes only a few minutes
- Occasionally just over an hour
Although brief, they can leave roads covered with snow and ice almost instantly.
