A squall line refers to a line of rigorous thunderstorms, which may form along or to the fore of a cold front. The term was used in the early twentieth century, as a synonym for a cold front. It consists of heavy precipitation, frequent lightning, hail, strong straight line winds, along with tornadoes and waterspouts. Ruthless weather conditions along squall lines may be expected in case, it reveals a line echo wave pattern or in case the line is in shape of a bow echo. The best warning of the occurrence of severe weather conditions down a squall line is when it morphs into a line echo wave pattern. A line echo wave pattern is a special arrangement in a streak of convective squalls, which indicates the incidence of low pressure area along with the probability of large hail, damaging winds, and tornadoes. Along every curve of the line echo wave pattern is a meso-scale low pressure area.
