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 line
A solid or nearly solid band of active thunderstorms. Generally, the distance between individual storms is less than the diameter of the individual storms. Accompanied by strong, squally winds.
squall line - A line of active thunderstorms, either continuous or with breaks, including contiguous precipitation areas resulting from the existence of the thunderstorms.
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 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 - A solid or nearly solid line or band of active thunderstorms.
Straight-line Winds - Generally, any wind that is not associated with rotation, used mainly to differentiate them from tornadic winds.
Squall line Any nonfrontal line or band of active thunderstorms.

Squall Line A line or narrow band of active thunderstorms. The line may extend across several hundred miles. It forms along and ahead of an advancing cold front.
SRH An acronym for Storm-relative Helicity.
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 line—Any nonfrontal line or narrow band of active thunderstorms (with or without squalls).
*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, or other heavy weather, often running parallel to, and ahead of, a cold front.

Squall Line
A line of heavy showers or thunderstorms often accompanied by strong and gusty winds.

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.
3. Squall Lines contain some of the most violent and turbulent weather known.
4. Squall Lines are usually parallel to a front.
Squall line - a solid line or band of active thunderstorms.
7. Anvil - The spreading out (by strong winds) of the upper portion of the thunderstorm. It usually has a fibrous or smooth appearance.
PRE-FRONTAL SQUALL LINE A line of thunderstorms that precedes an advancing cold front. Related term: squall line ...
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.
SPSSevere Weather Potential StatementSQLNSquall LineSquallA 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. 2.
Tail-End CharlieSlang for the thunderstorm at the southernmost end of a squall line or other line or band of thunderstorms.
MCSs may be round or linear in shape, and include systems such as tropical cyclones, squall lines, and Mesoscale Convective Complexes (MCCs) (among others).
It often forms a pseudo cold front or squall line on its leading edges. Also known as a bubble high. MESOLOW A small low pressure center the size of an individual thunderstorm. Its presence may increase severe weather potential.
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.
Four Basic Thunderstorm Types Thunderstorms occur in a variety of forms, sometimes as an isolated cumulonimbus cloud (anvil shaped), sometimes as a cluster of clouds, sometimes as a squall line, ...
A squall line seems to have crossed northern Victoria and the Riverina in the afternoon, because town after town reported a sudden terrifying increase in wind, and dust so thick that it put the town in total darkness for between five and 20 minutes.
Slang for the thunderstorm at the southernmost end of a squall line or other line or band of thunderstorms.
The derecho environment includes dry mid-levels winds that are ingested into a squall line or a segment of a squall line.
Mesoscale Pertaining to atmospheric phenomena having horizontal scales ranging from a few to several hundred kilometers, including thunderstorms, squall lines, fronts, precipitation bands in tropical and extratropical cyclones, ...
line squall"A squall that occurs along a squall line. This term is now confined mostly to nautical usage.
line storm"Same as equinoctial storm.
The scale of meteorological phenomena that range in size from several kilometers to around 100 kilometers. This includes MCCs, MCSs, and squall lines. Smaller phenomena are classified as microscale while larger are classified as synoptic-scale.
Size scale referring to weather systems smaller than synoptic-scale systems but larger than storm-scales ???ystems. Horizontal dimensions generally range from around 50 miles to several hundred miles. Squall lines, MCCs, ...
LEWP - Line Echo Wave Pattern. A feature within a line of storms that resembles a wave with a mesolow at the crest of this feature. Often associated with multiple bowing segments within a larger squall line.
cold front/trough passage/squall line/cloud changes/ppn changes etc.
Wind observations are very important, especially when noting severe convective events. Even without expensive anemometers etc.
