Squall Lines
Squall lines generally form along or ahead of cold fronts and drylines and can produce severe weather in the form of heavy rainfall, strong winds, large hail, and frequent lightning.
Squall Line - Any line or narrow band of active thunderstorms. The term is usually used to describe solid or broken lines of strong or severe thunderstorms.
Squall
A squall comprises a rather sudden increase of the mean wind speed which lasts for several minutes at least before the mean wind returns to near its previous value. A squall may include many gusts.

squall - 1. A strong wind characterized by a sudden onset, a duration of the order of minutes, and then a rather sudden decrease in speed. In U.S.

Squalls: 1) A strong wind which arrives suddenly, lasts minutes and ends with a sudden decrease in speed. 2) A severe local storm with strong. gusty winds and usually precipitation, may be accompanied by thunder and lightning.
SQUALL LINE: A non-frontal band, or line, of thunderstorms.
STATIONARY FRONT: A transition zone between airmasses, with neither advancing upon the other.
STORM: In marine usage, winds 48 knots (55 mph) or greater.
Squall Line - A solid or nearly solid line or band of active thunderstorms.
SQUALL A sudden onset of strong winds with speeds increasing to at least 16 knots (18 miles per hour) and sustained at 22 or more knots (25 miles per hour) for at least one minute. The intensity and duration is longer than that of a gust.
SQUALL LINE
A narrow band or line of active thunderstorms that is not associated with a cold front. It may form from an outflow boundary or the leading edge of a mesohigh.
Squall line Any nonfrontal line or band of active thunderstorms.

Squall
Atmospheric phenomenon characterized by an abrupt and large increase of wind speed by at least 18 mph and rising to 25 mph with a duration of the order of minutes, which diminishes rather suddenly.
SQUALL LINE - A line of thunderstorms or squalls extending over several hundred miles.
STABLE AIR - air with little or no tendency to rise, that is usually accompanied by clear dry weather.
Squall line A line of intense thunderstorm cells parallel to and ahead of a fast-moving well-defined cold front.
squall—A sudden increase in wind speed by at least 15 knots to a peak of 20 knots or more and lasting for at least one minute. Essential difference between a gust and a squall is the duration of the peak speed.
Squall- A strong wind characterized by a sudden onset in which the wind speed increases at least 16 knots and is sustained at 22 knots or more for at least one minute.
*Squall Line - A solid or nearly solid line or band of active thunderstorms.
Staccato Lightning - A CG lightning discharge which appears as a single very bright, short-duration stroke, often with considerable branching.
Squall Line - A line of solid or nearly solid thunderstorms or strong winds that might extend for several hundred miles.

Squall Line- A line of thunderstorms that forms along a front.
Stable Air- Air in which temperature and humidity at various levels discourage the formation of convection currents.

Squall Line - A line of thunderstorms sometimes several hundred miles long that can produce strong thunderstorms and sometimes severe weather.
Stable Air - Air that is colder than its surroundings and is resistant to upward movement.
SQUALL LINE - A line of convective clouds, such as thunderstorms, characterized by an abrupt change in wind speed and direction along the line. Structurally, squall lines are a "curtain" of updrafts along a relatively narrow path.
Squall Lines
1. A Squall Line is an area some 50 to 200 miles ahead of a front.
2. It is characterized by a formidable wall of turbulent clouds building to 40,000 feet or higher.

Pre-Hurricane Squall Line It is often the first serious indication that a hurricane is approaching. It is a generally a straight line and resembles a squall-line that occurs with a mid-latitude cold front.

Snow squallsIntense, but of limited duration, periods of moderate to heavy snowfall, accompanied by strong, gusty surface winds and possible lightning. In Canada, it is described that a snow squall brings strong winds, flurries and poor visibility.

Tail-End CharlieSlang for the thunderstorm at the southernmost end of a squall line or other line or band of thunderstorms.
West African Disturbance LineA line of convection about 300 miles long, similar to a squall line. It forms over west Africa north of the equator and south of 15 degrees North latitude. It moves faster than an Easterly Wave between 20 and 40 mph.
Lake Effect Snow SquallA local, intense, narrow band of moderate to heavy snow squall that can extend long distances inland. It may persist for many hours. It may also be accompanied by strong, gusty, surface winds and possibly lightning.
Strong cold fronts can set off atmospheric disturbances such as thunderstorms, squall lines, tornadoes, high winds and short duration snowstorms ahead of the moving cold front and cooler, drier weather as the front passes.
