Editing Alberta clipper (section)

==Effects==
The storms sweep in at high speed over whatever land they encounter, usually bringing with them sharp cold fronts and drastically lower temperatures. It is not uncommon for an Alberta clipper to cause temperatures to drop by {{cvt|16|C-change|0}} in as little as 10 to 12&nbsp;hours. Often, the storms bring biting winds with them, only increasing the effect of the lower temperatures. Winds in advance of and during an Alberta clipper are frequently as high as {{cvt|56|to|72|km/h}}. These conditions would cause [[wind chill]] values to drop into the {{cvt|-30|to|-45|C|0}} range across the upper Midwest and Great Lakes.<ref name="Islandnet">{{Cite web

Snowfall amounts with these systems tend to be small (on the order of {{cvt|2.5|-|7|cm|disp=sqbr}}), as the relative lack of moisture and quick movement inhibit substantial snowfall totals. However, several factors could combine to produce higher snow accumulations ({{cvt|15|cm}} or more). These factors include access to more moisture (which raises precipitation amounts), slower system movement (which increases snowfall duration), and colder temperatures (which increases the snow to water ratio). The southern and eastern shores of the [[Great Lakes]] often receive enhanced snowfall from Alberta clippers during the winter, due to lake enhancement. The [[lake-effect snow]] can add substantially to the overall snowfall total.<ref name="Islandnet"/>

Occasionally the clippers, when reaching the upper [[East Coast of the United States|Atlantic seaboard]] (usually north of Delaware), "[[bomb (meteorology)|bomb out]]" and can cause severe winter weather along the coast from Boston northward as Atlantic moisture is tapped. Snowfall amounts can approach {{cvt|6|–|12|in|order=flip}} or more when this happens. However, typically, Alberta clippers are not large snow producers south of Boston.

During the winter, Alberta clippers can occur somewhat frequently, with system intervals on the order of two to four days common during active periods.
