Editing Alberta clipper (section)

==Formation==
[[Image:MN weatherpatterns.svg|thumb|right|Typical winter storm tracks in Minnesota.]]

A clipper originates when warm, moist winds from the [[Pacific Ocean]] come into contact with the mountains in the provinces of [[British Columbia]] and then [[Alberta]].<ref name="Thurlow"/> The air travels down the [[lee side]] of the mountains, often forming a [[chinook wind|chinook]] in Alberta, then develops into a storm over the Canadian prairies when it becomes entangled with the cold [[air mass]] that normally occupies that region in winter. The storm then moves east-southeast riding the [[jet stream]], and passes off the upper Atlantic Coast, normally north of [[Delaware Bay]].

The chinook, which in part originates the Alberta clipper, usually brings relatively warm weather (often approaching {{cvt|10|C}} in the depths of winter) to southern Alberta itself, and the term is therefore not used in Alberta.
