From an Old Norse word, what term do weathermen sometimes use to describe a brief period of really heavy precipitation?

The term "squall" is typically used by weathermen to describe a brief, fast-moving band of heavy rain or snow that can cause flooding or major traffic headaches as it barrels through an area. Squalls are caused by highly-convective air or a strong cold front.
