A squall line is an elongated line of severe thunderstorms that can form along or ahead of a cold front. [25] [26] In the early 20th century, the term was used as a synonym for cold front. [27] The squall line contains heavy precipitation, hail, frequent lightning, strong straight line winds, and possibly tornadoes and waterspouts. [28]
A weather radar image of a mesoscale convective vortex (MCV) over Pennsylvania with a leading squall line. A squall line, or quasi-linear convective system (QLCS), is a line of thunderstorms, often forming along or ahead of a cold front. In the early 20th century, the term was used as a synonym for cold front (which often are accompanied by ...
A squall line is an elongated line of severe thunderstorms that can form along and/or ahead of a cold front. [11] [12] In the early 20th century, the term was used as a synonym for cold front. [13] The squall line contains heavy precipitation, hail, frequent lightning, strong straight-line winds, and possibly tornadoes and waterspouts. [14]
A squall line (commonly abbreviated SQLN) is a line of thunderstorms, most or all of which have attained severe limits, traveling in an organized fashion. The greatest threats within a SQLN are damaging winds, large hail, and flash flooding, though tornadoes are possible.
Of the four classifications of thunderstorms (supercell, squall line, multi-cell, and single-cell), supercells are the overall least common and have the potential to be the most severe. Supercells are often isolated from other thunderstorms, and can dominate the local weather up to 32 kilometres (20 mi) away. They tend to last 2–4 hours.
In the forefront, there are different cumulus species evolving from the cumulus mediocris to the cumulus congestus; behind, there are cumulonimbus calvus; finally, the huge cumulonimbus capillatus incus dominates the background showing a strong thunderstorm. A flanking line is an area of cumulus congestus or small cumulonimbus that mark an area ...

Flanking line is a line of small cumulonimbus or cumulus generally associated with severe thunderstorms. An overshooting top is a dome that rises above the thunderstorm; it is associated with severe weather.
