Straight-Line Winds - generally, any wind that is not associated with rotation, used mainly to differentiate them from tornadic winds.
STRAIGHT-LINE WINDS Any surface wind that is not associated with rotation. An example is the first gust from a thunderstorm, as opposed to tornadic winds.
Damaging straight-line winds often occur near the "crest" or center of a bow echo.
The potential for strong outflow and damaging straight-line winds increases near the bulge, which often resembles a bow echo. Severe weather potential also is increased with storms near the crest of a LEWP.
Plow WindA term used in the midwestern United States to describe strong, straight-line winds associated with the downdrafts spreading out in advance of squall lines and thunderstorms.
derecho"A widespread convectively induced straight-line windstorm. Specifically, the term is defined as any family of downburst clusters produced by an extratropical mesoscale convective system. Derechos may or may not be accompanied by tornadoes.
Supercells are rare, but are responsible for a remarkably high percentage of severe weather events - especially tornadoes, extremely large hail and damaging straight-line winds. They frequently travel to the right of the main environmental winds (i.
A microburst is a very localized column of sinking air, producing damaging straight-line winds similar to, but distinguishable from tornadoes.
Enhanced Wording - An option used by the SPC in tornado and severe thunderstorm watches when the potential for strong/violent tornadoes, or unusually widespread damaging straight-line winds, is high.
A non-rotating 'cloud' of dust raised by straight-line winds. Often seen in a microburst or behind a gust front.
If rotation is observed, then the term dust whirl or debris cloud should be used.

PLOW/PLOUGH WIND The spreading downdraft and strong straight-line winds preceding a thunderstorm. So named in the American Midwest because of its ability to flatten tall grasses as it passes. Related term: first gust ...
Bow Echo - a radar echo which is linear but bent outward in the shape of a bow (i.e., used by an archer). Damaging straight-line winds often occur near the "crest" or center of a bow echo.
DERECHO - A widespread event of very damaging straight-line winds. Usually associated with large squall lines.
Derecho: An hours-long windstorm associated with a line of severe thunderstorms. It is due to straight-line winds, not the rotary winds of a tornado.

Derechos include any family of downburst clusters produced by an extratropical MCS, and can produce damaging straight-line winds over areas hundreds of miles long and more than 100 miles across.
