Perhaps you are thinking of one of these terms:
* Snow squall: A brief, intense burst of snow that can significantly reduce visibility and make travel hazardous. These are often associated with lake-effect snow events.
* Blizzard: A severe winter storm characterized by heavy snowfall, strong winds, and low visibility. Blizzards can be extremely dangerous, causing power outages, transportation disruptions, and hypothermia.
* Whiteout: A condition where snow and wind create a blinding white haze, making it impossible to see. Whiteouts can be very dangerous, especially for outdoor activities and transportation.
If you can provide more context or information about what you are referring to, I might be able to give you a more specific answer.
