A squall or series of squalls extending along a squall line or instability line. The word squall is used to describe a strong wind that rises and dies away quickly. A line squall is a squall advancing on a wide front, sometimes hundreds of miles long, caused by the replacement of a warmer body of air by one colder. It is accompanied by a rapid rise in barometric pressure and a sudden fall in temperature.
