Imagine driving on a perfectly clear winter day, when suddenly, out of nowhere, you’re engulfed in a blinding blizzard that lasts only minutes.
That, my friends, is a snow squall: a brief, but incredibly intense burst of heavy snow accompanied by strong, gusty winds that can reduce visibility to near zero in mere seconds.
These aren’t your typical gentle snowflakes; they’re a sudden, dangerous surprise, often leading to rapid drops in temperature and slick, icy conditions, making driving extremely hazardous.
They usually form when a blast of cold air moves over a relatively warmer surface, like a lake, creating instability in the atmosphere that quickly generates a narrow, but potent band of snow.
Unlike a blizzard, which can last for hours, even days, a snow squall is a fleeting event, often passing in less than an hour, but its impact can be just as dramatic and perilous.
So, if you ever encounter one, remember: slow down immediately, turn on your headlights and hazard lights, and if possible, pull over safely until it passes. Stay safe out there!
