What is a snow squall?

Sorry if this is in the wrong section or doesn't even belong here at all but, what is a snow squall?

[Terminal Moraine]

It's a moderate-heavy snow shower accompanied by a temporary increase in wind speed to strong or gale force. During the shower there may be temporary blizzard like conditions but after it the wind decreases and, more often than not, the sun comes out.

A nice description of a snow squall in April 1908 from Philip Eden:
