“Conditions can literally go from sunny and calm to snowy with absolutely zero visibility in a matter of minutes, if not seconds.”

Surreal timelapse video posted by Aspen Snomass of a snow squall blowing through town Monday morning.  The National Weather Service defines a snow squall as the following:

“A snow squall is an intense short-lived burst of heavy snowfall that leads to a quick reduction in visibilities and is often accompanied by gusty winds. They may be characterized by one main squall or multiple squalls.”

ABC57 reports during the Aspen squall visibility was reduced to no more than 50 feet as the intense burst of snow moved across the city. Snow squalls can be incredibly dangerous and if there are warnings issued you should seek cover immediately.  The National Weather Service has its own special Snow Squall Warning Alert it issues to drivers when one is on the way.
