A snowsquall, or snow squall, is a sudden moderately heavy snowfall with blowing snow and strong, gusty surface winds.

- Snowsquall

A cold front, the leading edge of a cooler mass of air, can produce frontal snowsqualls—an intense frontal convective line (similar to a rainband), when temperature is near freezing at the surface.

In the United States, the National Weather Service defines a blizzard as a severe snow storm characterized by strong winds causing blowing snow that results in low visibilities.

Great Lakes Storm of 1913 November 7–10, 1913. “The White Hurricane” of 1913 was the deadliest and most destructive natural disaster ever to hit the Great Lakes Basin in the Midwestern United States and the Canadian province of Ontario. It produced 90 mph wind gusts, waves over 35 ft high, and whiteout snowsqualls. It killed more than 250 people, destroyed 19 ships, and stranded 19 others.

The Snowbelt is the region near the Great Lakes in North America where heavy snowfall in the form of lake-effect snow is particularly common.

The lakes produce snowsqualls and persistently cloudy skies throughout the winter, as long as air temperatures are colder than water temperatures, or until a lake freezes over.

Thundersnow, also known as a winter thunderstorm or a thundersnowstorm, is a kind of thunderstorm with snow falling as the primary precipitation instead of rain.

It can also occur from the lake effect or ocean effect thunderstorm which is produced by cold air passing over relatively warm water; this effect commonly produces snow squalls over the Great Lakes.
