A squall is a powerful, usually brief, burst of wind that usually brings rain or snow with it. When a snow squall blows across the mountain, skiers take a break in the ski lodge.
A squall is a violent, windy storm, often involving driving rain or snow. You can also describe a storm-like commotion as a squall, or the sound a wailing child or baby makes. In this case, you're using onomatopoeia, or a word that sounds like what it describes. Squall was originally a nautical word, used primarily by sailors to talk about weather at sea.
